What is 3D reconstruction computer vision?

In computer vision and computer graphics, 3D reconstruction is the process of capturing the shape and appearance of real objects. This process can be accomplished either by active or passive methods. If the model is allowed to change its shape in time, this is referred to as non-rigid or spatio-temporal reconstruction.

What is the method that can create 3D internal image of an object?

3D laser imaging – also known as 3D laser scanning, 3D laser imaging is the process of capturing data using laser beams which are exposed to the surface of an object. The captured data develops a 3D rendering with the assistance of a software.

Where is 3D reconstruction used?

3D reconstruction is used in the medical field through medical imaging equipment. This input data can then be used to create a 3D reconstruction of the original object or objects. A scan of a person’s body, for example, can be used to create a 3D model of that person in a computer system.

What is image based 3D reconstruction?

The goal of image-based 3D reconstruction is to infer the 3D geometry and structure of objects and scenes from one or multiple 2D images. Recovering the lost dimension from just 2D images has been the goal of classic multiview stereo and shape-from-X methods, which have been extensively investigated for many decades.

How is a 3D image made?

The traditional way of creating a 3D image is to capture two photos from slightly different angles to simulate the way our eyes perceive depth. If you’re shooting a stationary subject, that can be done by simply moving the camera slightly to the side in between shots.

What is SfM and MVS?

In essence, both techniques emerge from two different approaches: SfM aims to perform a 3D reconstruction using a structured (but theunknown) sequence of images while MVS is a generalization of the two-view stereo vision, based on human stereopsis.
