The utility model discloses a return mechanical return difference eliminator for tracking system of virtual studio, comprising a zoom gear arranged on the camera lens and a yawing gear arranged on the cloud platform. The cloud platform is provided with two return difference gears engaged respectively with the zoom gear and the yawing gear through a gear shaft. The return difference gear is a pair of identical double gears with certain dislocation on the tooth face. The assembly discards the remedial method of the later stage interpolation of the computer, and tracks the server to obtain the attitude parameters of the every time physical camera from the front end of the sampling directly, and without losing. The tracking speed of the physical camera for the virtual camera is no longer limited and the tracking precision is improved.
