Abstract

The invention provides an abnormal traffic light recognition method and device, equipment and a computer storage medium in the field of automatic driving technologies. The method comprises the steps that a state sequence of a traffic light which a vehicle is about to pass by in a travel process is acquired; the state sequence of the traffic light is matched with preset abnormal characteristics, and when a matching result is acquired, it is determined that the traffic light is an abnormal traffic light; and position information of the abnormal traffic light is acquired and recorded. Through themethod, recognition steps of the abnormal traffic light can be reduced, and recognition efficiency of the abnormal traffic light is improved.

Description

【Technical field】 [0001] The present invention relates to the technical field of automatic driving, in particular to a method, device, equipment and computer storage medium for identifying abnormal traffic lights. 【Background technique】 [0002] In the prior art, when identifying abnormal traffic lights, usually after the vehicle collects the driving data, the collected driving data is uploaded to the cloud server, and the cloud server performs data analysis, thereby realizing the identification of abnormal traffic lights. Therefore, the process of identifying abnormal traffic lights in the prior art is relatively cumbersome, and the identification efficiency is low. 【Content of invention】 [0003] In view of this, the present invention provides a method, device, device and computer storage medium for identifying abnormal traffic lights in the technical field of automatic driving, which are used to simplify the identification steps of abnormal traffic lights and improve th...
