Problems solved by technology

However, using the above two methods to restore the color of the signal light, it is impossible to avoid false detections of red and yellow lights, and it is also impossible to restore the shape of the traffic signal light, and the algorithm of the second method is highly responsible, so it is difficult to apply it to real-time scenarios

Abstract

The invention discloses a traffic signal lamp image processing method and a traffic signal lamp image processing device. The color and shape of an abnormal traffic signal lamp are recovered, and falsedetection of a red lamp and a yellow lamp are avoided. The accuracy of traffic signal lamp image processing is improved. The traffic signal lamp image processing method provided by the invention comprises the steps that the status of a current traffic signal lamp is determined, wherein the status of the traffic signal lamp comprises a red lamp status, a green lamp status and a yellow lamp status;the long exposure frame image and the short exposure frame image of the status of the current traffic signal lamp are collected; according to the long exposure frame image and the short exposure frame image of the status of the current traffic signal lamp, the shape of the current traffic signal lamp is recovered to acquire the shape recovery image of the traffic signal lamp; and color recoveringis carried out on the shape recovery image of the traffic signal lamp.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a traffic signal light image processing method and a traffic signal light image processing device. Background technique [0002] Electronic police cameras are generally high-definition digital cameras, which are connected to the traffic light signal system to monitor and detect vehicles at intersections. When a vehicle violates traffic lights, the electronic police camera will capture pictures of the illegal vehicle through image processing technology. Snapshots not only need to clearly record the process of vehicle violations, but also ensure that the vehicle number, signal light status, etc. can be clearly identified, so that the snapshots can be used as effective evidence for vehicle violations. However, when collecting illegal images of vehicles at traffic intersections, due to the dark light in some scenes, in order to clearly identify vehicle information...
