Passive position specific information of the camera a wide studio environment

摘要

In one embodiment of the present invention, the one camera, to send a signal detectable by multiple receivers, the method includes the step of placing the transmitter of the at least one. Is placed in a fixed position for the distance measurement of the camera relative to the receiver, multiple receivers performs the localization process of the distance measuring. The method further includes the step of the measurement range from range measurements collected based on a plurality of receivers located at known positions, to detect which point the movement of the transmitter in response to a signal from the transmitter get.
