DEVICE FOR DETECTING LIGHT SIGNALS AND METHOD FOR DETECTING LIGHT SIGNALS Russian patent published in 2018 - IPC G08G1/16 

FIELD: physics.

SUBSTANCE: device for detecting traffic lights includes a module (11) of the image capture configured to capture the image in the direction of the vehicle movement, and a traffic light detecting module (12) configured to detect the traffic light from the image. The traffic signal detection module (12) extracts the synchronized pixel (51) with a brightness that varies synchronously with the alternating current cycle of the electric power supplied to the traffic light and sets a predetermined range including the synchronized pixel (51) as the pixel group (50). The traffic signal detection module (12) then determines from the synchronized pixel (51) whether or not the traffic light is present when the synchronized pixel (51) is continuously extracted from the pixel group (50) during the predetermined detection period.

EFFECT: detection of even a remote traffic light with high accuracy.
