Abstract

The invention provides a vision-based front vehicle collision warning system and method, including: a vehicle front scene acquisition module, an effective area calculation module, a vehicle detection module, a vehicle positioning module, and a collision early warning module; the vehicle front scene acquisition module is used for recording The real-time road condition scene in front of the vehicle; the effective area calculation module is used to calculate the projection position of the detection area of ​​the self-lane in front of the vehicle and the left and right lanes adjacent to the self-lane in the image; the vehicle detection module is used to detect vehicles in the effective area, Determine the vehicle candidate area; the vehicle positioning module is used to obtain the confidence of the vehicle in the vehicle candidate area and the precise position of the lower bottom edge of the vehicle ahead; the collision warning module is used to issue different levels of warnings according to the collision time. The present invention can be applied to various bad weathers, provide vehicle collision time, set early warning levels, and timely and accurately make early warning prompts.

Description

technical field [0001] The invention relates to automotive electronics and collision warning technology, in particular to a vision-based front vehicle collision warning system and method. Background technique [0002] With the rapid growth of China's economy, the number of cars in China increases by millions every year. With the increase of road vehicles, the driver cannot in time discover the danger of rear-end collision with the vehicle in front due to fatigue, negligence and other reasons, causing rear-end collision accidents to occur from time to time. The front vehicle warning provides the driver with a front vehicle collision warning through the camera installed in front of the vehicle, and uses the on-board processor to process the image of the scene video in front of the vehicle, thereby improving driving safety. The vision-based collision warning system obtains the scene in front of the vehicle by the camera installed in front of the vehicle, so the vehicle detecti...
