Abstract	Optical positioning system is an important part in the computer aided surgery system. Under the previous research of the three linear CCD positioning system prototype, this paper proposed a new way to implement three-dimensional coordinates reconstruction of a marker in the digital signal processor while not in a computer as before. And the experiments were designed to calculate the markers' three dimensional coordinates in the DSP chip and the computer respectively, the results of the three dimensional coordinates' reconstruction showed that the calculation precision in DSP chip and the computer had no difference within 0.01mm error limit. Furthermore, the method that the three dimensional coordinates' reconstruction implemented in the DSP chip can improve the stability of the optical positioning system, and to the greatest extent to increase the calculation independent of hardware, while not depend on computer processing as before.
