Research on the 3D Reconstruction Method Based on Scale-invariant Feature Transform Feature Matching Algorithm

Hu Yingfeng  
In order to improve the precision of the 3D reconstruction for parts in reverse engineering based on binocular stereoscopic vision,the method of 3D reconstruction based on scale-invariant feature transform(SIFT) algorithm is proposed.With this method,through SIFT algorithm,two of the matching pixel points in corresponding digital images are found;and the image feature points are mapped into space lines using calibrated camera parameters.The coordinates of the three dimensional points are derived with approximation of the middle point of the common perpendicular line in different planes.This method does not require extra equipment to assist feature matching.The result of experiments shows that the method offers excellent robustness.
