The research of vehicles´ rear-view mirror contours´ visual pattern based on machine vision

In the process of dealing with traffic accidents, the contour of the car body parts is very important to the information of the vehicle body. By using image processing techniques and methods, this paper proposed a new type recognition system of rear-view mirror outline. We also designed the way of active and passive vision measurement in the image acquisition phase; discussed the way of using the Harsdorff distance of the fragments and the standard parts´ profile curve for image matching; and designed a database to achieve the query and comparison of fragments and standard parts.
