This paper proposed a new algorithm intituled a two-step method to estimate the posture of cameras located in multi-point of view. Firstly
the algorithm reconstructed the local 3D models of an object with the feature points in the first and second images. Secondly
the world coordinate frame was centered at local 3D models of the object
and every posture of the camera was estimated from the correspondences between the 3D feature points and the image feature points of the object. Experimental results on real images showed that the presented method is effective and the error of re-projection was less than 1 pixel.
