Stereo Matching of Single-lens bi-Prism Based Stereovision System
the equivalent of a stereo pair of images is formed synchronously as the left and right halves of a CCD image by a passive single-lens bi-prism based stereovision system. In the paper, we investigate the virtual cameras concept which is defined by two boundary lines: optical axis and CCD camera field of view (FOV) boundary line. Subsequently, a new geometry-based method which employs two fundamental theories: geometrical analysis of ray sketching in which all the pertinent points, lines and planes are expressed in 3D Camera Coordinates and the Rules of Refraction is presented, to achieve the stereo correspondence of the binocular stereovision system. By landing on the unique geometrical properties of the imaging system, the proposed method is free from the complicated camera calibration procedures and furthermore can be easily generalized to tri-ocular and multi-ocular stereovision systems to facilitate the solving of the computer vision problem. The performance of the proposed method is demonstrated in experiments and comparison with results from Projection method allows the assessment of our novel contributions.
