System Fault finding and Issues

1. The system states "no cameras detected"

Possible cause 1.

You didn't install the driver software as described above.

Possible cause 2.

You didn't select the option "using SSi Cameras" in the Setup Window as described above.

Possible cause 3.

You are not using the USB3 cables that are supplied with the system

and/or the cable power adapter is not plugged into the extension cables.

Possible cause 4.

You are not connecting the cameras to USB3 ports on the PC

(Usually only on the front of the PC)

2. I have two cameras but only one is detected

Possible cause 1.

You are not using the USB3 cables that are supplied with the system

and/or the cable power adapter is not plugged into the extension cables

Possible cause 2

You are using an older PC that can't supply sufficient power to power 2 cameras

Fix: Use the optional extra external camera power supplies

3. The CP states that the cameras are not registered

Cause

You are using an older version of the CP.

Cameras are registered in the CP software.

To fix: Install the latest version of the CP from the Tech News page on this website.

4. Cameras are detected but run slow and/or skip frames

Ensure you are only using the supplied USB3 cables with the 5v power adapter and that the cables are connected to only USB3 ports on your PC

If USB2 extesnion cables are used or the cameras are connected to USB2 ports, then the running FPS speed will be too low.

Also check that your camera exposure (shutter speed) settings are below 350 fps in the CP's camera panels.

Right Click on the "Defaults" button to automatically set this

Check the minimum PC requirements

Intel i5 or above Processor

Warning! Do not use PC's with AMD processors!

8GB RAM Nvidia 1070 Graphics Card or equivalent

25GB of Hard Drive Space

Windows 10 or 11 (Required)

Internet Connection

(Required if using 3rd party game software such as E6, TGC or GSPro)

USB3 ports (Required)

Note: The cameras are USB3 cameras

and will only run at the correct speed when connected via USB3 cables directly to separate USB3 ports

at the front of the PC.

USB Ports at the back of the PC don't usually work well

Checking the cameras speeds with the camera manufaturer's application

You can use the HuaTeng Vision application to check that the SSi cameras on your PC are running at the correct speed

Select "Continuous" in the Trigger panel to start grabing frames

Select "Manual" in the Exposure panel.

Set gain to 8.00 and Exposure time to 299 us

You should see at least a camera FPS rate of 790 FPS.

If not, then you are not connecting the cameras to USB3 ports on the front of the PC

or you are using USB2 extension cables

or you are not using the 5v adapter with the extension cables

If all else fails, unplug cameras, wait 2 seconds and plug them back in again

We have noticed that if a camera loses connection and comes back online again,

one of the cameras may start to run slow.

Currently we do not know what is causing this sporadic slow down

but unplugging the cameras and plugging them back in usually fixes the issue.

When doing this, ensure that the CP and/or HuaTeng app is shut down beforehand.

Camera speed check summary

1. All cameras are connected to USB3 ports in the front of the PC

Ports at the back of the PC don't usually work well

2. All cameras have a shutter speed setting of at or below 300 micro-seconds

Right click on the Defaults button in the camera panels to ensure this.

3. You are only using the supplied USB3 cables and not adding on additional extension cables

Adding addition extension cables will slow the frame rate down

4. You have tried connecting each camera separately

i.e. running the system with just one camera at a time to see if the problem is being caused by a one camera but not the other.

You may have to switch to VisTrak Eagle mode in the setup window for this test

5. You are using the current version of the CP

4.1

Each camera runs at full speed when connected to the PC separately

but when a second camera is connected,

the frame rate drops significantly.

This would indicate that your PC USB3 bus has insufficient bandwidth to cope with 2 cameras running at full speed.

You can try setting the cameras to 1500 fps in the CP's main panel and restarting the CP.

As the frame size is halved when setting the cameras to 1500 fps, you may be able get 600 fps or more when running the 2 cameras.

While not ideal, at least the system will then be playable.

5. I only see black or very dark blurry images

Possible cause 1.

Insufficient lighting

If using an overhead system like the Eagle, SCX or EVi, ensure all 4 lights are ON and pointing directly down on to the hitting mat,

that all brightness settings on the lights are set to 5000K

and that the spot size on the lights are set to 15 degrees

Possible cause 2

The cameras are not aimed at the ball on the mat

Important ! Both cameras have to be aimed such that the ball apears near the center of the screen

when the system is in "Full Ball Frame mode" as shown below

To help with aiming the cameras, switch to "Full Ball Frame" mode,

increase the camera exposure time by either right-clicking on the "Shutter Speed" button

(this will significantly increase the exposure time from its default 300 us to 5000 us)

or manually increment the exposure time by clicking on the UP Arrow key on you PC' keyboard.

Then set to "Video Stream Mode".

With the exposure time set to 5000 us, the images will be very bright and you will be more able to see what the camera is aimed at.

The above image (from a customer support session) shows how off the camera aiming is.

The system won't function with camera aiming this far off.

Possible cause 3.

The camera lens is not focused

It's important that the camera lenses are in focus.

To focus, place a ball on the center line of the enclosure and point the camera at the ball.

Switch to "Video Steam Mode" in the CP's camera window so that you see the captured images.

Rotate the outer dial on the lens in or out until you see that the ball is in focus.

Possible cause 4

The camera gain or shutter speed setting is set too low.

Default setting is 300 db for Gain

Default Shutter speed is 300 micro seconds

Possible cause 5

The lens aperture setting is not in the fully open position

(Only relevant if the lens you are using has an aperture dial)

7. The system finds the ball on the mat and shows the message

"Ball detected. Waiting for swing"

but doesn't detect a shot or the shot is way off

Possible cause 1.

Camera orientation is incorrect.

Ensure that when a club is placed behind the ball, the club is indeed shown behind the ball in the camera panel.

Use the X rev and Y rev options to flip the image

Note that direction of play is always shown right to left in the camera images.

Possible cause 2.

Insufficient lighting spread

The light spread should be sufficient to detect the ball anywhere in the FOV of the camera.

To test, put camera in Video Steam Mode and place ball at far ends (left and right, top and bottom).

You should see that the ball is detected in all of the FOV of the camera

Possible cause 3.

Shutter speed (exposure time) is set too high.

Max shutter speed should not exceed 400 micro seconds.

Default is 300 micro seconds.

If shutter speed is set too high, then motion blur will occur and the ball in flight won't be detected and thus no ball launch will occur.

Possible cause 4

The cameras are not aimed at the ball on the mat in Full Ball Frame mode

Switch to "Show Full Ball Frame" and Video Stream Mode mode

and aim the camera(s) so that the ball appears near the center of the image,

The above image (from a customer support session) shows how off the camera aiming is.

The system won't function with camera aiming this far off.

Important!

Only aim cameras when in "Full Ball Frame" mode

Do not try to aim cameras when not in full frame mode

System won't function in this case

7.2 The Control Panel detects the shot

but there's no launch in the golf game software

After a ball valid strike, the CP will show the Launch sent message

Probable cause:

The CP is not connected to the golf game software you are using.

When using GSPro, E6 Connect, TGC or Creative Golf game software,

an Internet connection has to be established.

You should therefore see the "Connected" message as shown above.

5. The system doesn't detect putts or small chips.

The message "Ball did not leave launch zone area" is displayed

Possible cause 1.

The system is not in putting or chipping mode.

For putts and small chips, the camera frame rate has to be slowed down.

The system is automatically set to Putting Mode when the ball is on the green or a putter is selected.

The system is automatically set to Chipping Mode when the ball is near the green or the user designated chipping club selected.

Possible cause 2.

The delay frames for putting or chipping modes are not set higher enough.

Adjust the "Putting delay frames" to 15 or higher in the VisTrak Video panel when in putting mode

Adjust the "Chipping delay frames" higher in the VisTrak Video panel when in chipping mode

To get into chipping mode, press the C key or designate a certain club as a Chipping mode club.

i.e. from the CP's main panel, select the club (left / right click on the club image)

and click the "Chipping Mode Club" radio button

Possible cause 3.

Your head is blocking the camera's view of the ball when you are bending down over the club.

Possible cause 4.

Even though the delay frames are set to their max value, ball still doesn't make it to the end of the launch zone

Note. A valid shot is only detected if the ball has been seen to leave the launch zone area.

In this case, place the ball closer to the forward edge of the launch zone area.

Chips not being detected?

Probably cause

You are using an older version of the CP software

Ensure you are using CP version V 10.0.7.1 or higher

Possible cause

The system is not in Chipping mode

and thus ball images are not detected outside the Launch Zone

To correct, either

1. Play the ball closer to the front edge of the launch zone.

2. Move the launch zone back.

3. Select a specific club as a chipping mode club in the CP’s main panel

(i.e. select the club you want to use as a chipping club by clicking on the image of the club and select “Chipping Mode Club”

4. Use TGC, E6 or GS Pro software

and select the “Chip Distance from Pin” in camera 1 panel.

Set the number of yards from the pin where Chipping Mode should kick-in. Default is 25 yards from pin.

Doing this will cause the system to automatically go into Chipping mode when the ball is within this distance but not on the green.

If the ball is on the green in the game software, the system will automatically go into Putting mode

5.2 The system doesn't detect small tap-in putts.

Probably causes

1. The ball wasn't detected leaving the launch zone area.

2. The ball didn't attain the minimum ball speed for a putt or shot

Even though the system maybe in "Putting Mode" so that the camera frame rate is reduced,

this reduction in frame rate may still not be sufficient to see the ball leaving the launch zone area.

A solution would be to place the ball very close to the forward edge of the launch zone area when attempting a tap-in putt.

Generally speaking - and to the best of our knowledge - no overhead camera tracking system can detect a 4 inch or so tap-in putt.

(and certainly no radar system, which at the best of times can't even detect a regular putt let alone a tap in putt)

Reason is because no system can differentiate between the player intentionally playing (i.e. tapping) the ball

and not just repositioning the ball on the mat with a club or foot if the ball is not seen to have left the launch zone area.

6. The cameras are reversed or images appear upside down

Possible cause 1.

The Cameras assignments are incorrect

With EVi and LX systems, the overhead camera is camera 1 and Vcam camera is camera 2.

If this appears to be reversed, click on the Swap Camera Positions.

With SCX systems, the left camera is camera 1 and right camera is camera 2.

If this appears to be reversed, click on the Swap Camera Positions.

After swapping, click the Fixed Assigns option ON

Possible cause 2.

The Xrev and or Yrev options are incorrectly set.

Change the Xrev and / or Yrev options to correct so that the orientation of the images appear as shown above

SCX camera orientation and direction of play

The direction of play in both left and right cameras is always from right to left in the image frames

To Check:

place and ball on the mat and lay a club down behind it.

After clicking the "Soft Trigger" button. your image in the left camera should look like the above image.

7. When I strike a ball, the CP always states "Ball did not leave the Launch Zone"

and shot is not detected.

Probable cause 1

Camera orientation is incorrect and the system is seeing the ball going backwards.

See the above section 6

Probable cause 2

You are using an older version of the Control Panel

Update to the latest CP version from the Tech News page

8. The CP stays in "Looking for ball in the Launch Zone" mode

Probable cause 1

The ball is not in the Launch Zone

Probable cause 2

The ball is in the Launch zone but the ball itself is not being detected

When the ball is placed on the mat, it should appear within the launch zone in both cameras after the cameras have detected it

Probable cause 3

The cameras are not aimed at the ball when in Fulll Ball Frame mode

With the "Show Full Ball Frame" and "Video Stream Mode" options switch on in the camera window,

ensure that the ball in both cameras appears approximately in the center of the images as shown above.

It doesn't have to be exact as the cameras will position the ball automatically.

Important!

Only aim cameras when in "Full Ball Frame" mode

Do not try to aim cameras when not in full frame mode

System won't function in this case

8. Ball not detected (1)

Bright objects or flooring in FOV of camera

Ensure there are no reflective objects or parts of flooring that reflect light in the FOV of the camera.

9. Ball not detected (2)

Measured Ball size not within limits

In the above example, the measured ball size was 46 pixels but the "Ball Max Size" setting was set at only 40 pixels.

10. Ball not detected (3)

The system cannot find the ball on the mat

System stays in "Looking for ball" mode

Ensure the ball is placed in the Launch Zone area in both cameras.

In order for a ball launch to be detected,

the ball must first be detected within the Launch Zone and then seen to have left the Launch Zone.

Ensure that the ball on the mat is within the launch zone area in the camera window in both cameras.

11. Ball not detected (4)

Do not use soccer balls!

The system requires the ball to be predominately white and balls with large black soccer markings on them

cause the system to either not detect the ball at all or the ball is detected as too small.

12. Ball not detected (5)

Insufficient lighting, cameras and lighting are mounted too high on the ceiling or shutter speed set too low

In the above case, the 150 us shutter speed is set too low for the amount of lighting.

Increasing to 300 us will fix the issue.

Ceiling mount height too high

If the cameras and lighting on the ceiling are mounted too high, then the amount of light getting down to the ball will be diminished.

Try to keep the mounting height below 9ft.

You can also adjust the Video Brightness/Contrast setting to increase the brightness of the ball

If the Brightness/Contrast setting is set too high, the ball will appear washed out. i.e. all white without any markings visible.

Improving image ball and club detection

using higher Contrast settings

Click the above image to see more examples of how higher contrast settings can improve image brightness with IR lighting

How the Floor GS (Grey Scale) setting effects the brightness/contrast setting.

If your lighting is insufficient to illuminate the ball so that it is detected when using fast shutter speed,

you will have to increase the Brightness/Contrast level.

In so doing, you may find that only the center of the ball is showing an increase in brightness.

This is because the brightness procedure is only increasing the brightness of pixels that have a GS above the floor GS level.

The idea is to only increase the brightness of the ball itself and not the surrounding floor so that a stronger contrast is made between the ball and the floor.

It is thus important that the Floor GS setting is set closer to the actual floor gray scale in order to increase the brightness of the complete ball.

Track lighting

Ensure all lights are pointing directly down onto the ball on the mat,

that all brightness settings on the lights are set to 5000K

and that the spot size on the lights are set to 15 degrees

IR lighting

If using IR lighting and the images seem dark,

you can do one or all of the following:

1. Increase the camera contrast setting

2. Use the optional extra Computar Lenses (that let in 30% more light)

3. Add additional CM Vision IR lights ($39 to $69 each)

- -

The above images were captured using only the standard IR lighting (3 x CM Vision 24 850nm)

at a distance of 8ft but with the new Computar M1214 lens.

13. Ball launches a shot immediately after detecting the ball

The system detects a ball strike by looking at 2 points on the ball on the mat.

A dark point and a light point.

The dark point is the pixel ahead of the ball - shown by the orange cross hair.

The light point is a pixel near the center of the ball.

The threshold is the Floor GS (Grey scale) which is user adjustable.

i.e. the dark point must be darker than the Floor GS level

and the light point must be lighter than the Floor GS level

When a ball is struck, the ball will move over the dark point, causing it to become light

and - as the ball has moved forward, the light point pixel will point to the floor and become dark.

If the Floor GS setting is set lower than the dark pixel point, then this will cause a ball struck detection

and the system will try to launch the ball.

To Fix:

Increase the Floor GS level so that it is greater than the dark point GS.

You can see the dark point GS by placing the mouse cursor over the area immediately ahead of the ball.

14. Ball launches when placing ball on mat

Fix: use CP version 10.0.5.3 or higher

CP Version 10.0.5.3 has improved valid shot check

to prevent inadvertent ball launches when bending down to place the ball on the mat.

15. Ball and Club speeds are too fast or too slow

Probable cause 1

Main cause of this problem is incorrect scaling factor

The scaling factor is used to convert distances measured in image pixels (as the camera sees them)

to real world distances measured in cm.

As a reference, the fixed diameter (42.67mm) of a golf ball is used.

In the above example, the ball size was measured at 50 pixels but the scaling factor of 0.1570 falsely converted the ball size to 78.50mm and not 42.67mm.

In this case, all distances will appear to be too long and thus ball and club speeds will be too fast

After setting the scaling factor correctly, ball and club speeds are correctly calculated

To Fix:

To set the scaling factor, place a ball on the mat and click the soft trigger in camera 1 panel.

Ensure that the ball has been correctly detected (as shown above with the aqua blue box lines around it)

and then just click the "Set Scale" button.

The scaling factor is then stored and shouldn't require any more adjustments.

Probable cause 2

Club Carry Factors are set ON and the setting for the particular club is not correct.

To Fix:

Swtich "Club Carry factors" OFF

set the factor with the slider bar to a setting that produces the correct carry results for the particular club being used

Possible cause 3

The vertical launch angle is not being correctly detected

16. I don't see the minimized CP after clicking on the Minimize button

If you don't see the Minimized CP after clicking on the Minimize Window button,

press the ctrl / Z to restore its position to the top left hand corner of the monitor screen

17. The system is not detecting correct club face, path or speed

Click the above button to read how to setup the system to detect club data with or without reflective stickers

18. Cameras run okay for a while and then stop running or go off-line

Probable cause 1

Your PC is not supplying sufficient power to the camera

Solution

Add external 12v power via the camera GPIO (General Purpose Input Output) cable

Possible cause 2

The supplied USB3 extension cables are not connected to the 5v power adapters that come with the cables

Possible cause 3

You have added additional extension cables other than the supplied cables to the cameras

19. Ball does not appear on the center line in the camera panels

The ball is only centered after the cameras have been started from the CP's main panel

and the ball has been located.

When you then go back to camera panels, the ball will appear centered.

The centering (i.e. ROI) is done separately for every shot as the next time you place the ball on the mat,

it is unlikely to be in the exact same position as the last shot and thus has to be centered again.

You can also manually center the ball by clicking the "Auto Center Ball - ROI" option off and on again

or clicking on the new "Center Ball in Image" button

Another reason could well be that your cameras are not aimed at the ball when in Fulll Ball Frame mode

Check your camera aiming

With the "Show Full Ball Frame" and "Video Stream Mode" options switch on in the camera window,

ensure that the ball in both cameras appears approximately in the center of the images as shown above.

It doesn't have to be exact as the cameras will position the ball automatically.

Important!

Only aim cameras when in "Full Ball Frame" mode

Do not try to aim cameras when not in full frame mode

System won't function in this case

20. How can I tell which camera is the Left

and which is the Right camera with an SCX system

When facing forward, the Left camera is on the left and right camera is on the Right

To confirm that the Control Panel is viewing this as such,

go to camera 1 in the camera panel,

select "Show Full Ball Frame" mode,

select "Video Stream mode"

and place an object (i.e. a club head) over the lens of the left camera.

You should see that the images go dark.

If not, then the camera positions are incorrect.

Click the "Swap Camera Positions" button to correct this.

Also, check the camera mounting orientation

Ensure that the cameras are mounted or rotated such that the silver label on the cameras are pointing outwards on both cameras

21. Balls go to the left or right even though I hit straight shots with an SCX

Probable cause

Cameras are out of alignment

Check camera alignment as shown below using 2 balls placed directly in-line with each other

Aim and rotate each camera until you see that the 2 balls

are pointing directly forwards towards the screen and in-line with each other.

Note that the balls don't have to appear exactly on the center line. Just relatively near is sufficient

The ROI ball centering will automatically do this for you.

Do this procedure for both the left and right cameras

22. Ball vertical launch angles are either too low or too high with my SCX

Probable cause 1

The stereo calibration tables haven't been initialized to their default values.

To fix

Download and install the latest CP update if using a CP version lower than 10.0.8.5

Probable cause 2

Cameras are out of alignment

To fix

Check camera alignment as shown above in section 21

23. Shots not being detected

There are a number of reasons why a shot is not being detected.

The first thing to check is whether or not the issue is caused by the CP not detecting the shot

or is it the game software not receiving the shot data?

To test, try making several shots with just the CP running. After every shot you should see the above message in the CP's main panel.

The CP should show an error message if the shot was not dected as a valid shot.

"Ball did not leave the Launch Zone"

A common problem is the above error message when making small chips.

See section 5 and 7 on this page for solutions to this problem.

If you're seeing other error messages

send us the shot video of the shot that is not being detected for analysis

see below section 24 below for this.

24. Other Shot accuracy issues

In order to resolve any other shot inaccuracy issues, we'll require you to send in the shot replay video for analysis

Shot Replay Videos

Important !

If your system is not detecting a valid shot, click the option

"Save non-valid shot videos" ON

in the CP Setup Panel

Retry a shot and make note of the shot Video number being saved.

After a shot, the shot video file name and number is displayed in the CP's main panel

The Vistrak system stores a shot video after every shot.

These shot videos can be re-called by clicking on the video number.

GSA Golf Technical support often requires the user to send us a copy of one or more of these shot videos

as an email attachment for analysis when issues occur.

The shot video files are stored in the C:\GSAgolf folder on your PC

25. Other issues

In order to resolve any other issues,

we'll require you to send in screen shots of the main panel, setup and camera panels.

How to make Screen shots

GSA Golf Technical support often requires the user to send us a control panel screen shots

To make a screen shot, press the PrtSc button on your keyboard.

Note: some CP screens have a Screen Shot button too.

This places a copy of the screen image into the PC's Clipboard.

You can then paste the image into the Paint application and save it.

Alternatively

You can then either paste or attach the image in an email to us for analysis
