[0044] Reference figure 1 The system of the present invention is mainly composed of a camera platform, an angle acquisition and platform control unit and a computer. among them:
[0045] The camera platform is composed of a camera, a pan / tilt and two absolute photoelectric encoders. The camera is placed on a fixed-position pan / tilt with a fixed optical center. It can perform 0 to 360 degree rotation and plus or minus 90 degrees of tilting movement. The camera transmits the collected real-time video data to the computer and the angle acquisition and platform control unit. Two absolute photoelectric encoders provide the rotation angle and pitch angle of the camera respectively.
[0046] The angle acquisition and platform control unit consists of a single-chip microcomputer, a serial port and a synchronization signal separation chip. The synchronization signal separation chip separates the frame synchronization signal from the video information and transmits it to the single-chip micr...
