| Abstract(in English) | Virtual studio is a popular technology for TV programs, that makes possible to synchronize computer graphics (CG) to live action shot with camera motion. Most popular method to obtain the camera parameters for CG drawing is utilizing the special platform and lens with rotary encoders, that can measure pan/tilt angles, zooming and focusing. However, any existing calibration methods for such camera systems have not enough accuracy. We developed the new calibration method for such camera system with high-power zoom lens and platform. To solve the camera parameters, we enhanced the bundle adjustment algorithm to fit the camera/lens model, and using pan/tilt data as known parameters. This paper clarifies our calibration method with concrete data, and discusses its effectiveness. |
