Research Of The Method Of 3D Reconstruction Based On Binocular Stereo Vision

In the field of computer vision research, binocular vision technology is a hotspotreseaching content that make use of computer software and hardware to simulate thebinocular vision of animals. According to the triangular geometric principles binocular visionobtains the object depth information, then reconstructs three-dimensional model of object. Itcan be applied in many areas such as reverse engineering, television animation, medicine,virtualreality, robot vision and so on. Binocular vision technology has a great value in thetheoey research and practical applications.The main work is as follows:(1) First build a hardware platform, including of binocular camera, optical len andcomputer.(2) Based on the principles of the calibration binocular camera employ chessboardcalibration method to obtain the internal and external parameters of Camera.(3) According to stereo matching method of feature points, make use of SIFT matchingalgorithm and SURF matching algorithm to match the corresponding pionts between twoimages.(4) Making use of the Bumblebe binocular camera, obtains two-dimensional images andcalculates the disparity map of the two images, then acquires the depth information of theobject.
