摘　　要：为提高视觉测量系统的测量精度,针对双目视觉系统结构,采用三角法建立了双目视觉测量系统的结构参数模型,分析了双目视觉系统结构参数与空间被测点之间的关系特性,研究了各结构参数对测量精度误差分布的影响,根据仿真结果给出了小误差时的结构参数的最佳取值范围。In order to improve the measurement precision for visual measuring system, tne influence of binocular vision structure was investigated. A structural parameter model of binocular visual measuring system was investigated with the trigonometric method. Through analyzing the measuring accuracy of the measuring point in binocular visual measure system, the effect of the structural parameters and the error transfer rules on the visual measurement were probed. According to simulation results, optimal value range of structural parameters is supplied while the error is small. Enough theoretical research is offered for optimization design of binocular visual measure system.
