Abstract

The invention discloses a traffic signal lamp fault detection method. The method comprises the following steps: obtaining an electronic police video stream under various weather conditions, and decoding the electronic police video stream to obtain traffic signal lamp image information, position information of a traffic signal lamp group in an image, and type information and position information ofeach signal lamp in the traffic signal lamp group; and setting a detection area and a lamp group area of the signal lamp group, If the detected signal lamp position is in the set lamp group area, counting the type and position information of the signal lamp in the set lamp group area. The method has the characteristics that the problems of small-range camera jitter and position offset are effectively solved, the false alarm rate of signal lamp fault detection based on the video is reduced, and the alarm accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of traffic signal lamp status monitoring, in particular to a traffic signal lamp fault detection method. Background technique [0002] At present, the correct setting and stable operation of traffic lights in cities are the basis for ensuring traffic safety and smoothness. A large number of existing traffic lights are still non-intelligent traffic lights without fault self-diagnosis capabilities. The fault detection of this type of traffic lights is mainly through on-duty traffic alarm repairs, traffic facility unit inspections and repairs, and citizen alarms. The above-mentioned fault detection method has problems such as high maintenance cost of traffic lights, and failure to be found in time. According to the actual application needs of urban road traffic signal lamp fault detection and maintenance, the automatic detection methods commonly used are: electronic circuit detection method and video recogniti...
