|Abstract:||The ability to acquire the accurate camera matrix of each frame of a video clip is essential if virtual content is inserted into the images in a believable way. This paper presents our system for inserting projected virtual content into broadcast tennis video based on camera matrix acquired. To achieve the accurate camera matrix, we develop a new algorithm for the 3D camera calibration of broadcast tennis video, which improves the accuracy of camera matrices via the proposed techniques of clip-wise data analysis and Hough-like search. We divide all the camera parameters determining a camera matrix into two categories: clip-varying and frame-varying. For the clip-varying ones, we use a clip-wise data analysis procedure to achieve their accuracy. For the framevarying ones, we use a Hough-like search to tune them for each frame. Preliminary experiments results show that we can seamlessly insert projected virtual content into each frame.|
