The image processing section allows adjusting the camera BW image to get the best point detection, depending on your lighting conditions and your setup. Therefore there are no recommended settings; you will always have to modify different parameters to get the best result.
The point detection will take effect for the white parts of the black & white image, not for the black parts.
The tracking can be done with two different methods:
1. Based on all colors in the camera image,
2. Based on a color you picked.
The default setting is based on all colors in the camera image. If you want to use the Color Tracking, please tick the check box [ColorTracking].
To set a color that should be tracked, activate the “CAM”-Mode in the camera settings section so that you see the colored camera image above.
Picking a color directly from the camera image:
Proceed a mouse-click on the desired color in the camera image. The box next to the ColorTracking check box will overtake this color.
Picking a color from the color picker box:
Click on the colored box next to the ColorTracking check box. Now you may choose a color from the list.
The inverted mode is enabled by default. In BW-Mode all lighter parts of the camera image will be shown in black, the darker parts will be shown in white, depending on the Threshold value. To disable the color inversion please remove the check.
As already mentioned above: The point detection will take effect for the white parts of the black & white image, not for the black parts.
Set up here the value for the threshold. The threshold defines which parts of the camera image will be converted into white and which ones into black parts when turning on the BW-Mode. It is related to the camera images luminance value by default. When Color Tracking is enabled, it is related to the special color chosen.
In the setup above the Color Tracking is enabled. The color was picked from the darker pink plane inside the camera image. The two pictures below show the tracking result depending on the threshold value.
Left image: The threshold value is very small (17), only the darker pink plane is tracked.
Right image: The threshold value is increased to 53. The lighter pink plane is now tracked as well.
Use this option to smooth the detected areas, so that rough pixels become smooth spots (0 = minimum blur, 15 = maximum blur).
Please be aware that increasing the blur value takes more performance!
This option inflates the detected areas (0 = minimum inflation, 15 = maximum inflation).
The result of the (eventually blurred and inflated) areas will be shrunk when using this option (0 = minimum shrinking, 15 = maximum shrinking).
There are no recommendations which values would be best to enter for Blur, Inflate and Shrink. It depends on your setup and especially the lighting conditions.
