Abstract

The invention discloses a traffic light state recognition method and device, electronic equipment and a storage medium, and relates to the technical field of automatic driving. According to the specific implementation scheme, the method comprises the steps that 1, determining that a current frame image acquired by a target vehicle-mounted camera on the vehicle detects traffic light equipment; andwhen it is determined that continuous N frames of images acquired by the target vehicle-mounted camera before the current frame of image track the traffic light equipment, traffic light state identification is performed in combination with the image area where the traffic light equipment is located in the current frame of image so as to obtain the traffic light state identification result of the current frame of image. Therefore, the traffic light equipment is tracked in a continuous multi-frame mode; false detection and missing detection are reduced; the accuracy of identifying the state information of the traffic light holder can be improved; and control planning can be carried out in combination with the determined state information of the traffic light holder.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the technical field of automatic driving, and in particular to a method, device, electronic device, and storage medium for identifying traffic light states. Background technique [0002] In the autonomous driving technology, in order to ensure that the autonomous driving vehicle can safely pass through the intersection, the autonomous driving vehicle needs to be able to detect the status of the traffic lights at the intersection in real time, and recognize the red, green, and yellow lights. The control system of the vehicle, the control system issues a pass or stop command according to the state of the light. [0003] In the traffic light state recognition method in the related art, because the traffic light equipment detection algorithm or model is prone to detection errors (such as false detection and missed detection of traffic light equipment), the output traffic l...
