As the virtual class studio system core technology, camera positioning and tracking technology is a hot topic at present. Graphics identification camera positioning and tracking system has data processing time is long, a large amount of video delay. Virtual class should be used for electromechanical sensing mode to realize the camera positioning and tracking. Analysis of the camera calibration method, gives the electrical sensor tracking process and precision based on. The scheme has the camera positioning and tracking with little delay, parameter precise and reliable advantage. This is a virtual class studio more appropriate positioning and tracking method.
