Problems solved by technology
[0003] Because the relationship between the focal length of the camera and the angle of view cannot meet the appropriate shooting conditions, it is easy to cause traffic accidents. For example, when the traffic light exceeds the angle of view of the camera, the visual perception recognition system will mistakenly believe that there is no traffic light; or when the traffic light is small in the angle of view of the camera , will cause the visual perception recognition system to be unable to clearly recognize the traffic light

Embodiments of the present invention provide a method and device for traffic light recognition, involving multiple cameras, and the fields of view of any two cameras have an overlapping relationship. The method includes: acquiring image data collected by the multiple cameras; A camera collects image data to determine a target camera; the target camera is used for traffic light recognition. Through the embodiment of the present invention, multi-camera fusion visual perception recognition for traffic lights is realized, and image data is collected through multiple cameras to screen out the most suitable camera for traffic light recognition, avoiding traffic light omissions caused by viewing angle restrictions, The accuracy and reliability of traffic light recognition are improved, which can effectively reduce the occurrence of traffic accidents.
Description
technical field [0001] The invention relates to the field of image technology, in particular to a traffic light recognition method and device. Background technique [0002] In the traffic light visual perception recognition system, the pictures taken based on a single forward-looking camera are usually used for traffic light recognition. [0003] Because the relationship between the focal length of the camera and the angle of view cannot meet the appropriate shooting conditions, it is easy to cause traffic accidents. For example, when the traffic light exceeds the angle of view of the camera, the visual perception recognition system will mistakenly believe that there is no traffic light; or when the traffic light is small in the angle of view of the camera , will cause the visual perception recognition system to fail to clearly recognize the traffic lights. Contents of the invention [0004] In view of the above problems, it is proposed to provide a traffic light recognit...
