A Survey of Depth Estimation Based on Computer Vision

Currently, the method based on computer vision for depth information extraction and depth estimation is widely used. It can get depth information from 2D images, depth maps, or binocular vision images and has been a popular application in the field of artificial intelligence such as depth detection, pose estimation, as well as 3D reconstruction. This paper introduces the basic theory and some implementation methods of depth information acquisition based on computer vision. As well, it briefly summarizes the existing research results and makes an outlook on the future development trend of the field.
