Multi-camera complex scene self-adaptive vehicle collision early-warning device and early-warning method

Abstract

The invention provides a multi-camera complex scene self-adaptive vehicle collision early-warning device and method. The multi-camera complex scene self-adaptive vehicle collision early-warning deviceis characterized in that a multi-camera sensing module includes three fixed focus cameras whose focal lengths are sequentially reduced, and the multi-camera sensing module transmits the detected front image information to a data processing and calculation module; the data processing and calculation module performs vehicle detection, vehicle tracking, and front and rear distance calculation on theimage information according to a set built-in collision warning method, and generates collision early-warning information; and a collision warning module receives the collision early-warning information, and generates warning information to a driver for warning prompt. As the three fixed focus cameras of the multi-camera complex scene self-adaptive vehicle collision early-warning device cover thewide detection range, and also avoid the problems of high cost and large size caused by using a zoom camera. The multi-camera complex scene self-adaptive vehicle collision early-warning method performs scene classification on classifiers to enable the cascade classifiers to be small in volume, high in detection efficiency, and more highlighted in vehicle features in the corresponding scene, so that the complex scene adaptive ability of the system is high.

Description
