An image composition apparatus includes a synchronization unit for synchronizing a motion capture equipment and a camera; a three-dimensional (3D) restoration unit for restoring 3D motion capture data of markers attached for motion capture; a 2D detection unit for detecting 2D position data of the markers from a video image captured by the camera; and a tracking unit for tracking external and internal factors of the camera for all frames of the video image based on the restored 3D motion capture data and the detected 2D position data. Further, the image composition apparatus includes a calibration unit for calibrating the tracked external and internal factors upon completion of tracking in all the frames; and a combination unit for combining a preset computer-generated (CG) image with the video image by using the calibrated external and internal factors. |
