Abstract：In order to improve the measurement precision of binocular stereo vision measuring system, a new structural parameter model of this system was investigated with the trigonometric method to analyze the structural parameters affect on the vision measurement accuracy. Then, by simulation, the precision influence trend of these structural parameters was got to conclude the range of the structural parameters with a small error. And, the simulation result could be applied to the meridian visualization. By pasting the location target on the electrode probe, the coordinates of the probes was calculated by using the relationship of target and electrode probes to indirectly get meridian point position. Also, by analyzing the accuracy of the X corners on the target, this experiment obtained an effective work area which laid a good foundation for the meridian visualization. Finally, according to the theoretical and experimental results, the method of improving system precision was summarized.
