Surface Texture Reconstruction for 3D Object Based on Cylindrical Back-Projection Algorithm

Extracted texture from the image used for texture mapping is a commonly used method of 3D reconstruction.However,the texture obtained by camera will usually distortion,can not be directly used for texture mapping,so study the texture correction is necessary.An cylindrical back-projection algorithm was proposed for cylindrical objects,image texture on the cylindrical surface was projected onto 2D plane,and the defect pixels were corrected with linear interpolation algorithm,then SIFT algorithm was used for feature extraction and matching on corrected texture image.Finally,the seamless automatic image mosaic was completed with smoothing algorithm,wide viewing angle image was got.Experiments show that these methods can effectively generate the texture for 3D reconstruction.
