| Abstract: | In this paper, the typical structure of virtual studio is introduced, the method of obtaining the parameters of the moving camera based on the radial alignment constraint and the pinhole camera model which concerned radial lens distortion is analyzed. A new advanced algorithm which based on the union encoding method of the comparing and scaling value between two characteristic point is put forward, A core technology of virtual scene of high level virtual studio is realized. Through actual application, it demonstrates that this algorithm has better performance in speed and stability comparing to all the others. |
