Along with the economical development, the automobile enhances unceasingly in our country's inventory. The automobile profession takes the national support the pillar industry, has the very big promoter action to national economy's development. In recent years, the independent road sense's research and the application in domestic and foreign developed rapidly, was honored as the automobile profession the next technological revolution. This topic basis independent road sense's demand, studied one kind to be possible to use in independent driving the range measuring system. This system take the binocular range finder as a principle, may supply around the automobile body the object distance information, the precise periphery object distance information is the independent road sense foundation, thus this topic research results have the broad application space. Carries on regarding the binocular range finder's analysis under the OpenCV environment, OpenCV takes one kind to open the source the machine vision function storehouse, in the last few years along with the edition renewal, the function strengthened gradually, has involved machine vision nearly all domains. The research on two-sided visual in the OpenCV environment, simplified the binocular vision development step, sped up the development progress.
