How it works
Calibration
The calibration calibrates the camera which is used to detect the balls thrown on
the wall. Once the system is calibrated, it is not necessary to repeat the operation
for each use if you don’t move the mobile unit. At the slightest movement of the
camera, a calibration will be necessary for a good detection.
Calibration can also be performed when balls detection on the wall is not accurate
or when there are false detections. To calibrate the system, follow the steps below:
01 Select the gear icon from the home page.
02 Click on the button.
03 Press the “I” button on the Lü keyboard remote to display the camera’s
stream. Move the position of the stand to adjust the camera feed with the
projection surface. Make sure the red area is outside the green rectangle.
Note : The red area represents the undetected area of camera detection.
04 Choose the calibration method that suits you best: Automatic or Manual.
05 If the calibration fails, try the other method.
06 After the calibration is complete, select Test mode. Throw a few balls
at different places in the projection to test the detection accuracy.
