How 3D structure is reconstructed from multiple images of same 3D scene?

1.2 The principle behind stereo-based 3D reconstruction is very simple: given two images of a point, the point's position in space is found as the intersection of the two projection rays. This procedure is referred to as 'triangulation'. yields the 3D shape and configuration of the objects in the scene.

How are 3D images reconstructed?

3D reconstructions can be obtained by directly interfering with the environment using light projectors. Active reconstruction systems that include an integrated RGB camera are called RGB-D sensors as both a color and a depth value can be associated with each image pixel.

What is image based 3D reconstruction?

In this project we developed a purely image-based approach to fusing foreground silhouette information from multiple arbitrary views for applications like 3D reconstruction. Our approach does not require 3D constructs like camera calibration to carve out 3D voxels or project visual cones in 3D space.

Which are the methods associated with 3D reconstruction?

The survey takes a look at the major reconstruction methods, which are; Laser triangulation, Stereoscopy, Conoscopic holography and Moiré Interferometry. A review of the major producers of scanning technology for 3D reconstruction is also carried out. 3D reconstruction methods are classified into passive and active.
