Texture based 3D shape reconstruction from multiple stereo images

摘要

Describes a 3D shape reconstruction method including an improvedstereo matching technique and a new shape connection technique. Toreconstruct the 3D shape for an object, a stereo camera is moved aroundthe object and several stereo images of the object are captured fromdifferent view points. Each stereo image is then analyzed to obtain therange data using the improved stereo matching technique. Each obtainedrange data represents shape for a part of the object. These object partshapes are connected to reconstruct the 3-D shape for the object, usingthe proposed shape connection technique. The shape connection techniquereconstructs the shape for an object using object part shapes themselvesand textures on the object part shapes. It is not necessary for thistechnique to measure camera positions and directions accurately whenstereo images are captured
