Abstract:

The paper analyses the algorithm of camera self-calibration. In the virtual studio, a calibration algorithm based on planar points is put forward. App  lying the experimental method designed by ourselves, we can compute the intrinsic camera parameters. The results prove the precision of the algorithm fo r camera calibration in virtual studios.

Key words:  （camera calibration, self-calibration, intrinsic parameters, virtual studio）
