Abstract

The invention discloses a method for tracking and identifying a headlight and a taillight of an automobile under visual perception. The method comprises the steps of video image acquisition, local space automotive light detection, global space automobile detection, automotive light track real-time tracking, and matrix type LED particle control. On the basis of intelligent image recognition and tracking technologies, a camera is used for collecting and storing an automotive head target and an automotive tail target in front of an automobile; with a target detection and tracking technology and a feedback correction model, orientation, speed, and position motion parameter detection of the automobile by a vehicle in front of the automobile can be realized; and with an image view and an LED illumination area mapping model, adaptive controlling of single or grouped light brightness in a matrix type LED headlamp is realized by using a visual image sensing parameter as a control input. Therefore, stable multi-target vehicle tracking can be realized on the condition of complex light and the headlight of the automobile can be adjusted in real time based on a tracking result, so that the method can be applied to a headlight intelligent control service in auxiliary automobile driving.

Description

technical field [0001] The invention relates to a method for detecting automobile lights, in particular to a method for identifying and tracking automobile headlights and taillights under visual perception. Background technique [0002] With the rapid development of computer technology, sensor network technology, new energy, and intelligent control technology, the application of automotive advanced assisted driving, safety interconnection and other technologies has been continuously expanded. Driven by the drive to promote innovation in the entire automotive industry. As an important part of car design, vehicle lighting is the most important information received by the driver's visual nerve during night driving. The main problem of driving a vehicle at night is the problem of sight of the road ahead. Although the traffic flow is generally low at night, the traffic The accident rate is relatively high. The reason is that due to the too far exposure range of the high beam or...
