What is 3D model reconstruction?

What is 3D model reconstruction?

October 2019) 3D reconstruction from multiple images is the creation of three-dimensional models from a set of images. It is the reverse process of obtaining 2D images from 3D scenes.

Why 3D reconstruction is important?

Three-dimensional object reconstruction Reconstruction allows us to gain insight into qualitative features of the object which cannot be deduced from a single plane of sight, such as volume and the object relative position to others in the scene.

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.

Where is 3D reconstruction used?

The task of generating fast and accurate 3D image reconstruction has found its application in the field of computer vision like robotics, entertainment, reverse engineering, augmented reality, human computer interaction and animation.

What is the 3D reconstruction?

The 3D reconstruction consists of the following sections: 2D digital image acquisition is the information source of 3D reconstruction. Commonly used 3D reconstruction is based on two or more images, although it may employ only one image in some cases.

Is it possible to reconstruct 3D structures from 2D video sequence?

3D reconstruction is a major problem in computer vision. This paper considers the problem of reconstructing 3D structures, given a 2D video sequence. This problem is challenging since it is difficult to identify the trajectory of each object point/pixel over time.

Are there any real-time algorithms available for 3D reconstruction?

Mostly algorithms available for 3D reconstruction are extremely slow and cannot be used in real-time. Though the algorithms presented are still in infancy but they have the potential for fast computation. Delaunay method involves extraction of tetrahedron surfaces from initial point cloud.

How does reconstruction work?

Reconstruction of the surface is performed using a distance function which assigns to each point in the space a signed distance to the surface S. A contour algorithm is used to extracting a zero-set which is used to obtain polygonal representation of the object.
