Q: Does the camera have to be postion towards the red traffic lights..or is it triggerd once lights go red?

A: Color recognition is triggered when it detects the selected (any) color in the specified area in real time. The module is designed for independent work to intercept an object by a color, or to work in conjunction with other modules like License Plate Recognizer, for example, detecting violations of traffic rules in combination with a traffic light (detection of drivers ignoring the red signal).

Choose a color for detection from the suggested basic ones or input a color in the RGB or HSV color scheme. Use the Sensitivity threshold slider to allow detection of undertones of a selected range. Paint the area where color should be monitored in red with a brush. Areas not marked in red will be ignored when searching for colors. Select the “Analyze only the changing areas” to ignore static objects in camera image (the module will look for moving objects only then). You will need a “Motion Detector” module in the chain before module if you want to use this feature.

Did you face issues while testing? You may send us some video examples from your camera and your
settings.dat file, so that we can hold experiments on our side.
