In this paper, the visual servo based and the lateral steering radius, etc. This measurement measurement method for vehicle geometric parameters system is not sensitive to the camera's calibration is studied. Sobel operator is applied to get the edge error, thus the precise relative position of the vehicle enhanced image. The characteristic points, such as wheel center and rim point , are detected with the tthe test rm is nced application of Hough transformation . A servomechanism is carried out , which is driven by the deviation between feature point and the camera optical axis.
