Abstract
The binocular stereo vision measurement system with two CCDs, whose optic axes are parallel, is presented in this paper to measure the 3D profile of a dynamic object in long distance. Two key technologies in the binocular stereo vision measurement system are dissertated. The first technology is to extract the features of two images which are separately gathered by two CCDs. The second technology is to process the feature pairs to build a corresponding relationship of different feature points of the same space point and get the disparity image. Experiment results of stereo matching and 3D profile of measured object are given. These results show that the mathematic model is simple relatively, stereo matching is easy comparative, and the measurement is rapid. And the presented binocular stereo vision measurement system can be used to measure the attitude and 3D profile of flying missile, and the measurement system which requires some hardware, can be realized easily, operated stably and is of high measurement precision.
