Video stream based detection method for high-beam headlamps

Abstract

The invention discloses a video stream based detection method for high-beam headlamps. The method comprises the following steps: 1, a video stream is obtained and decoded; 2, high-beam headlamp areasare detected; 3, whether high-beam headlamp turn-on images of a vehicle are to be acquired is judged, when the high-beam headlamp areas are discovered, a camera is controlled by a data processor to perform shooting to obtain the high-beam headlamp turn-on images of the vehicle, and the images are used as evidence of misuse of the high-beam headlamps; when the high-beam headlamp areas are not discovered, the high-beam headlamps of the vehicle are not turned on, and detection for next traffic video stream is started. The method adopts simple steps and is reasonable in design and good in use effect, the high-beam headlamp areas in each frame of the traffic video streams are detected, so that whether the vehicle turns on the high-beam headlamps can be detected effectively and accurately in real time, and the evidence of vehicle traveling with the high-beam headlamps turned on is obtained timely.

Description

technical field [0001] The invention belongs to the technical field of high-beam detection, and in particular relates to a high-beam detection method based on video streams. Background technique [0002] According to the analysis of traffic accident data over the years, among traffic accidents at night, traffic accidents caused by car drivers abusing high beams account for about 30%-40%. Automobile high beams have become an important hidden danger of road traffic accidents at night. one. The hazards caused by high beams of automobiles to traffic safety mainly include instant blindness, decreased perception of distance and speed, and decreased ability to judge width. Regarding the use of high beams of vehicles not in accordance with the regulations, it is clearly stated in Article 48, Paragraph 5, Article 51, Paragraph 3, and Article 58 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China". According to the legal requir...
