| Abstract: | Dot structured light is mainly applied to measure one-dimensional distance and to obtain the location of object in one direction. In this paper, a novel calibration method on vision location system is presented based on the unvariance of cross-ratio in algebraic and projective geometry. It is unnecessary to calculate the intrinsic parameters and extrinsic parameters of CCD camera with this method. Therefore, the number of error sources is decreased and the reliability of the system is increased. Also, Experiment is shown in the paper. |
