DEVICE FOR DETECTING TRAFFIC LIGHTS AND METHOD OF DETECTING TRAFFIC LIGHTS Russian patent published in 2017 - 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 light detecting module (12) specifies reference signals (L01-L03), the number of which is a multiple of three and the phases of which are offset relative to each other by the time obtained by dividing the AC power cycle applied to the traffic light by a multiple of three, and adjusts the reference signal phase (L01), which is the closest to the phase of the AC power, to the AC power phase. The traffic light detecting module (12) extracts a synchronized pixel from the image (53b) with a brightness, which varies synchronously with the reference signal (L01) having the phase adjusted to the AC power phase, and determines that the traffic light is present at the position of the synchronized pixel.

EFFECT: detecting traffic lights from a long distance with high accuracy.
