Abstract: Epipolar geometry and projective geometry between uncalibrated images in stereo vision system is analyzed and a geometrical method for projective reconstruction of stereo vision is presented after proving the relationship between the plane projective coordinates and stereo projective coordinates. The accurate nonlinear algorithm is adopted to compute the homography and projective coordinates . Experimental results demonstrate a high degree of accuracy of 3D reconstruction. -
