Study On The Environment Of Measurement And Spatial Localization Based On Binocular Stereo Vision

Along with the development of the application of spatial data in many fields, the traditional 2-dimension expression of spatial information is not able to satisfy the request on the usage of spatial information. The binocular stereo vision has provided a direct analog of biological vision, which not only could realize the "real 3-dimension", but also can express the spatial location and relationship accurately. The construction of the binocular stereo vision environment is the basis of the deep research and concrete application for itself, this paper has seriously proposed the research on a series of critical problems involved.In this paper, the environment of measurement and spatial localization based on binocular stereo vision has been researched. According to the biological vision mechanism, this paper has proposed three basic foundations to construct the binocular stereo vision environment, including the degree of overlap, the separation picture and the parallax. Analyzing the quantitative relation between the axis and the depth perception to naked eyes under natural conditions, the relationship between the depth perception and parallax in the computed imaging system has been proposed. The horizontal parallax, vertical parallax and resolution power are three critical sides that influence stereo visual comfort. Combing the study on the Panum fusion area, this paper puts forward the constraint conditions of visual comfort of binocular on them. Central projection is the most important imaging modes in image gain. Based on the study on the principles of photogrammetry, this paper has analyzed the effect of degrees of freedom of central projection on the effective angular field and the parallax of homologous image point. The binocular has received frequent usage in the satellite remote-sensing positioning, so this paper has made a detailed research on the method that gets the geodetic coordinates of object from its picture coordinates by the RFM normal form.This paper has gotten the quantitative relationship between the picture parallax and the object depth, and the related formulas have been also derivate. The constraint conditions of visual comfort on the related influence factors have also been gotten. The quantitative relationships between the degrees of freedom of central projection and the effective angular field and the parallax of homologous image point are derivate. Finally the solution to the problem how to get the accurate geodetic coordinates by the Rational Function Model has been given, and on the foundation of the research a practical system has been designed. Finally the application program has been realized by the programming language.
