Abstract

The invention relates to the field of intelligent traffics, and discloses a signal lamp state detection method and a signal lamp state detection system based on video processing. The detection method and the detection system are secure and effective, and are low in complexity, so that a signal lamp state can be detected reliably with relatively high precision in real time, and powerful enforcement evidences are supplied to public security traffic departments. The method comprises the following steps of: determining a signal lamp region position in a video frame image comprising a signal lamp by using a positioning algorithm; analyzing chroma information, brightness information and saturation information in the extracted signal lamp region position, and determining the state of the signal lamp according to an analysis result; and sounding an alarm for the signal lamp in an abnormal state. Aiming at the shortcoming of relatively complicated mounting process of the conventional traffic signal lamp detector for signal lamp state detection and the shortcoming that the hardware cost of a product is increased because an extra signal lamp power line is required to be connected, the signal lamp state detection method and the signal lamp state detection system have the advantages of mounting simplicity, high detection stability and high precision, and extra hardware cost is not required.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to an electronic police signal light state detection technology. Background technique [0002] As an important branch of the intelligent transportation system, the electronic police system comprehensively uses advanced technologies such as digital image processing, pattern recognition and artificial intelligence to capture and deal with traffic violations such as running a red light, and provides strong law enforcement evidence for the public security and transportation departments. It has played an important role in traffic order, ensuring traffic safety, improving the capacity of road intersections and reducing traffic accidents. [0003] At present, the state of the signal light in the electronic police system is mainly obtained through the traffic signal light detector. The traffic signal light detector collects the state of the signal light at the intersection of the r...
