Aiming at the problems of the vehicle collision that happened in lane changing,a method of detecting the road area behind the vehicle including side blind zone is proposed.The method divides lane marks side-back into two parts inside and outside to research sequentially.Therefore,it solves the problems that the left and right regions of interest(ROI) are dissymmetrical which is caused by the position of the camera.The closing vehicles are identified through shadow detection which is based on the gradient characteristics in the lane area.Based on these,the distance between two vehicles is computed based on their geometrical position and monocular vision.Experiment show that the methods can detect the lane marks and vehicles exactly,meantime the distance between two vehicles is estimated effectively when their real distance was within 55meters.
