The invention discloses a method for establishing a relation between a scene
stereoscopic depth and a vision difference in a binocular stereoscopic vision
system. the method comprises the steps of firstly, solving inner parameters, and relative rotary matrixes and translation vectors of left and right cameras; then, analyzing a main error source and an error model of the binocular stereoscopic vision
system; then, analyzing influences of the main error on a
base line length and the vision difference of the parallel binocular stereoscopic vision
system; then, establishing a common relation model of the scene
stereoscopic depth and the vision difference in the binocular stereoscopic vision system; obtaining depth information by a
laser distance
measuring instrument by selecting a certain amount of demarcation points and carrying out demarcation based on a least square method to solve a relation model between the scene
stereoscopic depth and the vision difference in the binocular stereoscopic vision system; and finally, solving the vision difference in left and right images through a corresponding fixed matching method so as to realize accurate
recovery and three-dimensional reestablishment of the scene stereoscopic depth. The method has the beneficial effect of directly, simply, accurately and extremely improving the accuracy of the stereoscopic depth
recovery and the three-dimensional reestablishment.
