摘　　要：针对双目立体视觉测距中产生误差的问题,分析了系统中的各个参量,并建立了双目立体视觉测距系统的误差模型。得出引起测量系统误差最大的两个参量是CCD摄像头的对准程度和测量的距离;在视场中心的距离测量精度低,边缘测量精度高,在视场中心的水平和纵向的测量精度却远高于在边缘的测量精度两个结论。基于本文建立的误差模型可以指导适用于具体应用场合的双目立体视觉测距系统的设计。The parameters that caused errors in stercoscopic measurement system were studied. Measuring error models were established. There were two important factors that cause big measuring errors, the degree symmetry of two cameras and the measuring-distance. The measuring-accuracy of distance in the center of view field is lower than the edge of view field. But the measuring-accuracy of endwise and crosswise in the center of view field is much higher than the edge. Based on this errormodel two eves stereoscopic measurement svstem is designed.
