The Vcam C is a ceiling mounted vertical launch angle detection camera.
It is either an Add-on to VisTrak Base or VisTrak IR system.
The Vcam C is a high resolution camera that measures the ball image size of the ball in flight
and translates this size to a ball height that is then used to calculate the launch angle of the ball.
The system functions for both left and right handed players.
The Vcam C is a standard feature of the VisTrak IR VC
The Vcam C uses a 25mm lens for close up hi-resolution images of the ball
If you see the above warning message in the camera windows, then the camera assignments are not correct.
With the VisTrak IRVC, camera 1 is the ball launch angle camera and camera 2 is the VisTrak camera.
Follow the above instructions to re-assign the cameras to their correct positions.
If the camera assignments aren't correct, then the CP may hang and just show a white screen when started.
1. unplug all cameras from the PC.
2. restart the CP and switch the "Fixed Assigns" option OFF.
3. shut the CP down.
4. plug the cameras back into the PC and restart the CP.
5. Check that assignments are correct.
If it's a 2 camera system, then camera 1 is the Vcam camera and 2 is the VisTrak camera.
If it's a 3 camera system, then camera 1 is the Vcam camera, camera 2 the Hcam camera and 3 is the VisTrak camera.
If re-assigning cameras then the "Fixed Assigns" should be switched back ON again and the CP re-started
Initial Setup Process
Ensure that the ball size has been correctly detected as in the above screen shot.
The default calibration table was made with the camera mounted at a height of 8.5ft.
Re-calibration shouldn't be necessary as the table is essentially linear.
If you would like to re-calibrate then press the * key to start the recording mode.
Start with the ball at ground level and the row cursor set at 0 height.
The calibration table is made in 2cm height increments.
Repeat this process 25 times
Mounting the Vcam C
The Vcam C is mounted next to the VisTrak Eagle Base or VisTrak IR
If using a VisTrak IR VC, then the Vcam C is already mounted in the LED panel
Vcam C frames
The Vcam C captures 2 frames of the ball.
1. At floor level before ball strike
2. Shortly after ball strike
In frame 1, the size and position of the ball image is captured when the VisTrak camera detects a ball on the hitting mat.
In frame 2, the ball image is captured shortly after ball strike
and its size and position is compared to the size and position it was in frame 1.
Alternative vertical launch camera systems
Stereoscopic camera system
A floor mounted camera that views the ball from the side.
