A Survey of Image-based 3D Reconstruction
Xinfang Fu, LI Yue-qiang · 2017
Image-based 3D Reconstruction is the inverse process of geometric drawing, however, the lack of information makes it difficult to reconstruct the 3D image.The methods of 3D reconstruction using object contour information contain manual interactive operation, stereo vision, motion image, photometric stereo.Based on the degree of automation of image-based 3D reconstruction technology, the difficulty of the algorithm and the quality of 3D reconstruction, the researchers analyzed and studied the advantages and disadvantages of various methods, respectively.Technical difficulties mainly in three aspects contain matching problems, precision problems, speed problems.The researches pointed out the challenges and the future development direction of the 3D reconstruction based on vision.This technology is still in the exploratory stage and there is a long way to put it into practice.
