摘　　要：为精确规划激光跟踪仪的测量站位,提高飞机装配效率,本文提出基于虚拟力场的激光跟踪仪可测性量化判定方法。首先,根据测量中的距离约束、垂直测量角约束和障碍物可视性约束,构建激光跟踪仪可测性约束表达式。然后,引入虚拟力场,改进虚拟斥力公式,并定义阈值公式,构建障碍物可视性判定模型。最后,构建可测性矩阵,以实现激光跟踪仪的可测性量化判定。试验结果表明,与势能场法对比,基于虚拟力场的激光跟踪仪可测性量化判定方法具有较强的可行性和较高的准确率。In order to plan the laser tracker measuring station accurately and improve aircraft assembly efficiency, a method is proposed to judge the laser tracker measurability quantitatively based on the virtual force field. Firstly, the constraint expressions of the laser tracker measurability are constructed according to the constraints of distance,vertical measurement angle and obstacle visibility of measurement. Secondly, an obstacle visibility judgment model is constructed by introducing a virtual force field, improving the virtual repulsion formula and defining a threshold formula. Finally, the measurability matrix is constructed to realize the quantitative judgment of the laser tracker measurability. The experiment results show that the proposed method has better feasibility and higher accuracy than potential energy field method.
