This paper introduces the vision technology for auto-navigation on the lunar surface in CE-3 project. The basic principle of stereo vision by navigation cameras and hazard cameras is explicated. The idiographic reality including inner parameter correction, epipolar line rectification, DOG filter, dense matching, disparity map filter and 3D coordinate calculation are described in details and the process...
Video transmission is a key technology of security monitoring systems used in underground constructions. The video transmission based on carrier wave is an emerging and promising technology compared with the widely used technologies using coaxial cable, twisted-pair wire, optical fiber, and wireless wave. The study presents a novel design scheme of image transmission system based on carrier wave....
An articulated hand tracking method which can be used in virtual touch screen system (VTSS) using monocular camera is proposed. The VTSS is a novel vision-based interactive surface without the need for physical touch screen. The articulated hand model provides more information than fingertips to be in touch with the interactive surface. Using a simplified kinematic model of the hand, a rough estimation...
