TRAFFIC LIGHT RECOGNITION METHOD AND TRAFFIC LIGHT RECOGNITION DEVICE Russian patent published in 2022 - IPC G08G1/00 G08G1/09 G08G1/16 B60R21/00 G06K9/00 H04N7/18 

FIELD: traffic light recognition.

SUBSTANCE: invention relates to a traffic light recognition method and a traffic light recognition device. A traffic light recognition method, comprising the steps of obtaining a plurality of images by repeatedly forming a traffic light image, obtaining a sequence of results consisting of a plurality of determination results in the order of time sequence, obtaining a stop line location, calculating a first distance from the vehicle location to the stop line location . When setting the numeric threshold based on the first distance, the first threshold is set as the numeric threshold in the case where the first distance is equal to or greater than the distance threshold. Setting the second threshold less than the first threshold as a numerical threshold in the case where the first distance is less than the distance threshold, and outputting the last determination result in the case where the number of determination results identical to the last determination result exceeds the numerical threshold, from the results of the determination, constituting the sequence of results. The traffic light recognition device comprises an imaging unit and a controller.

EFFECT: increase in the accuracy of image recognition is achieved.
