The traffic_light_map_based_detector Package#

Overview#

traffic_light_map_based_detector calculates where the traffic lights will appear in the image based on the HD map.

Calibration and vibration errors can be entered as parameters, and the size of the detected RegionOfInterest will change according to the error.

traffic_light_map_based_detector_result

If the node receives route information, it only looks at traffic lights on that route. If the node receives no route information, it looks at a radius of 200 meters and the angle between the traffic light and the camera is less than 40 degrees.
