Abstract

An embodiment of the invention discloses a method and a system for recognizing traffic lights by an automobile data recorder. The method includes acquiring to-be-recognized images captured by a frontcamera of the automobile data recorder; if the to-be-recognized images include traffic light identities is confirmed, recognizing passing indication information in the traffic light identities; providing the passing indication information to on-vehicle users. By the method and the system, the automobile data recorder can have an automatic traffic light recognition function, and the passing indication information of the traffic lights is provided for the on-vehicle users, especially the on-vehicle users with color blindness or color weakness or driving with fatigue, so that traffic safety levelis further improved, and the possibility of accidents is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle equipment, and in particular to a method and system for identifying traffic lights through a driving recorder. Background technique [0002] With the continuous development of the economy, the transportation is more and more convenient, and more and more cars enter ordinary families, which makes people's quality of life continue to improve, but on the other hand, the number of cars on the road is increasing, and the distance between pedestrians and vehicles There were also some contradictions. Traffic lights have become a very important tool for traffic safety and traffic hubs. For drivers, especially color-blind, color-weak or fatigue drivers, it is very dangerous to run a red light because they cannot distinguish the color of the traffic light when crossing a traffic light intersection. , can easily cause traffic accidents. [0003] However, the current driving recorder i...
