In this paper, we propose a method for generating graphic objects having realistic shadows inserted into video sequence for the enhanced augmented reality. Out purpose is to extend the work of [I], which is applicable to the case of a static camera. to video sequence. However, in case of video, there are a few challenging problen~s, including the camera calibration problem over video sequence. false shadows occurring when the video camera moves and so on. U7e solvr these pro1)lrms using thr convenient calibration trchnique of [2] and the information from video sclclucnce. We present the experimental results on real video sequences.
