In robot location, it is necessary to determine the three-dimensional position and orientation of a calibration object relative to the camera from its monocular image.This paper presents a new method for such determination. A rectangular parallelepiped which exists in most scenes is chosen to be our calibration object.The advantages of our method arc as follows: 1. Our calibration object can be in any arbitrary position and orientation relative to the camera without requiring some of the camera parameters to be known beforehand.Even now most authors still require that calibration object be placed in special position and orientation relative to the camera, and also that some of the camera parameters are known beforehand.Zhou et al in 1986[4] and Chen et al in 1989[5] waived the requirement that the calibration object be placed in a special way but they still required that some of the camera parameters be known beforehand. In the present paper,it is shown that all camera parameters can be calculated uniquely. 2. Unlike Ganapathy's method [8],our method can estimate the camera parameters uniquely. It is known that constraint in the perspective projection transformation and the orthogonal matrices should be exploited as fully as possible so as to improve estimation. Ganapathy makes partial use of such constraint and his method has gained wide acceptance. But some of Ganapathy's calculation equations are still nonlinear and the solution is not unique. Our method makes full use of such constraint in addition to the fundamental equations of perspective projection. Because full constraint is utilized, all the equations are simple and non-trigonometric and the solution is unique. Because full use of constraint is made,our method also gives accurate estimation even in the presence of disturbance.

A camera calibration method for stereoscopic disparity metrology is described and discussed. It uses stereoscopic images of same objects with known position as input. Based on the projective geometry,and initial estimate of camera parameters is determined,and then the accurate estimate of camera parameters is computed by an iterated algorithm using the least square method.

本文提出了一种摄像机参数的测定方法,该方法利用已知实际相对位置的几个物点的左右两幅图像,根据投影几何学的定理确定摄像机参数的初值,通过最小二乘方估计和逐步逼近的方法算出满足精度要求的摄像机参数.
