Research Of Parameters Theory Based On Prism Monocular Stereo Vision System

Stereo vision is a big branch of computer vision.After researching and developing for more than 40 years,is has been played a more and more important role in industry,medical treatment and aerospace.Monocular stereo vision measurement based on prism was proposed as the development of stereo vision.The theory’s proposing accelerates the development of stereo vision’s research and it has a wide future of system theory.With the hard work of researchers in this field,monocular stereo vision research has experienced from the theoretical derivation to the system implementation,from the parameter estimation to precise calculation,from simple system to complex system.The method that has been proposed has become an important branch of stereo vision measurement.However,many problems have occurred in the Monocular stereo vision measurement system during the research,including the imperfection of calibration,the difficulty of adjust the distorted images and the uncertainty of results of pictures taken by the system.Facing these problems,this article has proposed an optimization of system parameters based on prism,aiming at refining the results of pictures taken by the system.The main research contents come below:Step 1,Put forward the change of public area.Analyze the different situation of public area using the basic principal of Monocular stereo vision.With the help of principle of geometrical optics,compute the optical system parameters,which was stimulated by OpenGL,and come out with the effect of public area by system parameters.Step 2,Research on parameter optimization.Use the program to stimulate the change of the system as the angle of prism changes and come out with a regularity analysis,with which we can get the condition of imaging of five different Monocular stereo vision systems.Under these conditions,the law of change of public area using different distant parameters can calculated,which becomes a principal law.Step 3,Experiment of proofing the theory.Using experiments to proof the effect of parameters on public areas of images.Camera calibration principal and parameter configuration have been used during the building of the systems.Reasonable parameters can be get by several experiments of taking photos for calculating public areas.Use matlab to deal with the pictures and calculate the pixels of public areas,from which we can get the principal of changing of public areas.The results of the experiments show that the optimization method of Monocular stereo vision system based on prism is reasonable.By theoretical calculation and experiment,different imaging results can be get by different system configurations.The principals of changing of public areas are influenced by the changing of object distance.As a result,we can get the best optimized configuration of Monocular stereo vision system parameters according to the request of practical applications.
