| Abstract: | A new method for automated detection of position error of vehicle headlight shape is introduced,by using the image manipulation edge recognition,introducing arithmetic method of outline track to obtain the image edge of vehicle headlight,and analyzing with curve approximation method,and then the sub-pixel matching point is obtained through evaluating its derivative function.The experimental results show that the method can accurately locate the image edge of vehicle headlight shape and enhance the speed of calculation.The method is better than the traditional measurement. |
