Abstract: The thesis used the geometric characteristics of collinear points to get the intrinsic parameters of the came-ras.Firstly,the homographic matrix between space collinear points and its image points is used to get the linear constraints of the intrinsic parameters and the intrinsic parameters for multiple cameras.Then,according to the coordinates of collinear points before and after movement in each camera,the rotation matrix and translation vector of the camera relative to the reference camera are obtained,and the outside parameters of the cameras are solved.Finally,simulation data and real image experiments show the feasibility and effectiveness of this method.

Key words: Multiple cameras, Collinear points, Homographic matrix
