Structure from motion (SfM) is an important task in computer vision. Two-view SfM, which means SfM from a pair of images, is the foundation of incremental SfM methods and is quite useful in some real applications. Based on the analysis of camera geometry, this paper proposes a two-view SfM algorithm. The proposed algorithm is able to use the rotation information naturally. Simulation and experimental...
Pose estimation from points with unknown correspondences currently is still a difficult problem in the field of computer vision. To solve this problem, the SoftSI algorithm is proposed, which can simultaneously obtain pose and correspondences. The SoftSI algorithm is based on the combination of the proposed PnP algorithm (the SI algorithm) and two singular value decomposition (SVD)-based shape description...
Controlling robots based on human motion recognition visually has attracted much attention recently. Classical methods are mainly with single viewpoint, like interaction via Microsoft Kinect depth sensor. However, such methods will strictly limit the interaction range and human users have to face the visual sensor. Stereo vision methods are helpful to implement a viewpoint-free system. Visual hull,...
