The automatic rotating pan-tilt controller 107 is mounted on the tripod 112; the digital camera 101 is fixed on a digital camera fixing bracket 102 at the top of an automatic control rotating platform 106, and the pitching angle of the digital camera can be controlled through a pitching angle fixing knob 103. The automatic rotating pan/tilt controller 107 is mounted on a tripod 112. A panoramic photo shooting program is written in the memory of the automatic rotating pan-tilt controller 107, and the automatic control of the pause and the rotation of the rotating pan-tilt 106 and the control of the whole shooting process action of the digital camera 101 are controlled. The portable computer 121 is provided with a full-automatic intelligent control instant synthesis software program, and automatically and intelligently controls the identification, loading, image alignment, image correction and image synthesis from the image just shot by the digital camera 101 until each link of image output is sequentially linked and operated.
The digital camera 101 is connected to an automatic control circuit board 111 in an automatic rotation pan/tilt head controller 107 via a digital camera shutter control line 105 and a shutter signal PC sync line 106. The digital camera 101 and the USB interface in the portable computer 121 are connected via a dedicated USB data transmission line 104.
