摘要
点结构光主要用于一维距离的测量,也适于物体的一维定位。文中基于代数射影几何中的交比不变性,提出了由点激光器和CCD相机构成的视觉系统的新的标定方法、它不需要计算CCD相机的内外参数,减少了测量误差源、提高了测量的可靠性。最后进行了相应的实验。
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.
