Overview of 3-D Reconstruction from Images

This article summarizes recent advancements of the theories and techniques for 3-D reconstruction from multiple images. We start with the description of the camera imaging geometry as perspective projection in terms of homogeneous coordinates and the definition of the intrinsic and extrinsic parameters of the camera. Next, we described the epipolar geometry for two, three, and four cameras, int...

Reconstruction of 3-D Figure Motion from 2-D Correspondences

We present a method for computing the 3D motion of articulated models from 2D correspondences. An iterative batch algorithm is proposed which estimates the maximum aposteriori trajectory based on the 2D measurements subject to a number of constraints. These include (i) kinematic constraints based on a 3D kinematic model, (ii) joint angle limits, (iii) dynamic smoothing and (iv) 3D key frames wh...

3-D Map Reconstruction from Range Data

When 3 D Reconstruction

3D reconstruction from a single image is a classical problem in computer vision. However, it still poses great challenges for single-view reconstruction of daily-use objects with irregular1 shapes. In this paper, we re-consider the problem of single-view 3D reconstruction in terms of two CV areas: category modeling and knowledge mining from big visual data. Category modeling & task output: For ...
