TRAFFIC-LIGHT RECOGNIZER AND TRAFFIC-LIGHT RECOGNIZING METHOD Russian patent published in 2017 - IPC G08G1/09 

FIELD: physics.

SUBSTANCE: traffic-light recognizer (100) receives (11) the image data (D08), forming an image of the vehicle environment, detects (12) the vehicle own position and detects, in the image, the traffic-light near the vehicle. The traffic-light recognizer identifies (23) two or more traffic-lights that, as predicted, are to be captured in the image, based on the home position information (D05) and map information (D02) containing the position information on the traffic-lights, and assigns (24) the priority level to each of the two or more traffic-lights identified in this way, based on the probability of blocking the traffic-light in the visibility zone. When two or more traffic-lights are identified, the traffic-light detected (15) in the image is the traffic-light with the highest priority level among two or more traffic-lights.

EFFECT: improving the probability of detecting traffic-lights, when it is predicted to capture two or more traffic-lights in the image.
