Abstract:
    The invention provides a calibration method of the model parameter for the single camera dummy mouse system. It bases on the two-dimension entity drone and the two-dimension dummy drone. The entity drone coordinate system is as the agency to get the equation of the screen plane of the non-visible field in the camera coordinate system. At the same time it sets the mapping relation of the figure coordinate of projection point which is the three-dimension control point in single camera dummy mouse system and the screen coordinate. The screen coordinate is input into the computer system to control the computer. The method does not need the assistant adjusting device and is easy to operate, has the high calibration ratio. So it has improved the available visible field and the operation time.
