System and method for front vehicle collision early warning based on visual sense

Abstract

The invention discloses a system and method for front vehicle collision early warning based on a visual sense. The system comprises a vehicle front scene obtaining module, an effective area calculation module, a vehicle detection module, a vehicle positioning module and a collision early warning module. The vehicle front scene obtaining module is used for recording the real-time road condition scene in the front of the vehicle; the effective area calculation module is used for calculating projection positions of detection areas a bicycle road ahead of the vehicle and a left lane and a right lane which are adjacent to the bicycle road in an image; the vehicle detection module is used for detecting vehicles inside the effective areas and determining a vehicle candidate area; the vehicle positioning module is used for obtaining the confidence coefficient of the vehicle inside the vehicle candidate area and an accurate position of the lower rim of the front vehicle; and the collision early warning module is used for publishing early warnings of different levels according to the collision times. The system and the method are applicable to various server weathers, provide vehicle collision time, set the early warning level and timely and accurately make early warning prompt.

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...
