Simplified 3D Motion Tracking

詳細技術說明

This new method is an inside-out vision-based tracking system based on cameras arranged in an orthogonal configuration of two opposing pairs. The arrangement of cameras moves along with the object being tracked, and can be mounted on a mobile platform for use in robotic applications such as tracking, localization, and mapping. A computing device receives a series of images from each camera and calculates successive positions for the object, simplified by the arrangement of cameras in conjunction with polar correlation of optical flow, in order to determine an objectΓÇÖs three-dimensional motion.

*Abstract

UCF researchers have developed a motion tracking method independent of external components commonly relied upon by conventional approaches by utilizing environmental markers as reference points or pre-loaded models of the physical environment instead. The method consists of four cameras, such as digital video cameras, capturing a series of images from each quadrant of view when arranged in a square-shaped setup. The images are used to compute a series of positions and orientations of the object with attached cameras, reducing the complexity of computing an objectΓÇÖs three-dimensional motion. Simplified positions and motion tracking applications include video game controllers, human-computer interaction input devices for scrolling, pointing, and tracking, and input devices for interacting with virtual environments.
