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

FIELD: traffic light recognition.

SUBSTANCE: invention relates to a traffic light recognition method and a traffic light recognition device. The 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. When setting a numerical threshold value based on the specific determination result that is the last determination result of the determination results constituting the sequence of results, the first threshold value is set as the numerical threshold in the case where the specific determination result is the determination result that the display state is display permission that allows the passage of a stop line corresponding to a traffic light. A second threshold value smaller than the first threshold value is set as a numerical threshold value in the case where the specific determination result differs from the determination result that the display state is a resolution display. The traffic light recognition device comprises an imaging unit and a controller.

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