Stereo vision three dimensional reconstruction system and method

Abstract

The embodiment of the invention provides a stereo vision three dimensional reconstruction system and method. The stereo vision three dimensional reconstruction system includes a first camera, a second camera and a computer, wherein the first camera and the second camera are fixedly connected; the first camera and the second camera synchronously move around an object to be reconstructed, and synchronously acquire the images of the object to be reconstructed at a plurality of visual angle positions; and the computer determines the motion relationship of the first camera at the plurality of visual angle positions according to the images acquired by the first and second cameras, and reconstructs the three dimensional model of the object to be reconstructed according to the motion relationship and the images acquired by the first camera at the plurality of visual angle positions. The scheme of the stereo vision three dimensional reconstruction system and method has the advantages of avoiding usage of the third party calibration equipment, thus being conductive to reduction of cost, improving the accuracy of data, being conductive to recovery of the real-dimension surface morphology of the object to be reconstructed, and avoiding usage of object motion control equipment.

Description

technical field [0001] The invention relates to the technical field of three-dimensional reconstruction, in particular to a stereoscopic three-dimensional reconstruction system and method. Background technique [0002] At present, the methods of multi-view reconstruction using stereo vision technology mainly include: single-camera / dual-camera multi-view reconstruction around object movement, single / dual camera fixed object rotation to achieve multi-view reconstruction, multi-camera fixation and acquisition from multiple angles Object surface image reconstruction, etc. The first method is flexible to use, but requires third-party equipment to calibrate the movement of single / dual cameras, and the restored 3D shape often cannot obtain the real physical scale of the measured object, and can only obtain an approximate model; the second method requires additional Object motion control equipment is expensive and inflexible in use; the third method often requires pre-calibration o...
