【Abstract】 In this paper, a method based on stereovision for measuring the pose of multi-degree freedom mechanisms is put forward. In the method, the camera model has the parameters, with definite physical meanings, and the deformation of the lens is also taken into account. These parameters can be obtained by the least-square algorithm. Furthermore, the 3D reconstruction of multi-points is simple. Since the matching of points and their reconstruction can be completed simultaneously, less calculations are needed. Experimental results show that the method can achieve pose measurements with higher precision.更多还原
