Research on 3D Object Reconstruction Method based on Deep Learning

Abstract

3D reconstruction is a classic task in the field of computer graphics. More and more researchers try to replicate the success of deep learning in 2D image processing tasks to 3D reconstruction tasks, so 3D reconstruction related research based on deep learning has gradually become a research hotspot. Compared with the traditional 3D reconstruction methods that require precision acquisition equipment and strict calibration of image information, the 3D reconstruction method based on deep learning completes the matching of 2D images to 3D models through deep neural networks, and can reconstruct 3D models of various categories of objects from RGB images obtained by ordinary acquisition equipment in a large number and quickly. This paper introduces the state of the art of 3D voxel reconstruction, 3D points cloud reconstruction and 3D mesh reconstruction, respectively. According to the different representation methods of 3D objects, the 3D object reconstruction methods based on deep learning are classified and reviewed, the characteristics and shortcomings of existing methods are analyzed, and three important research trends are summarized.
