摘　　要：为了验证激光跟踪在位测量过程中路径规划的正确性,避免误操作,基于OpenGL图形库建立了被测齿轮的三维模型,利用3DsMax建立了三维平台和激光跟踪仪的模型并导入到所研发的测量仿真系统中;利用轴对齐包围盒(axis aligned bounding box,AABB)法实现测头与被测齿轮的触碰检测;系统可与雷尼绍UCC2控制器通信,读取当前测头坐标以更新计算机仿真测量系统中三维平台的状态,实现测量过程仿真.测试结果表明:该系统运行稳定,实现了特大型齿轮激光跟踪在位测量的仿真和测头与齿轮的触碰检测.To verify the path planning in the laser tracking in-situ measuring process and to avoid fault operation, the simulation of the measuring process was realized. A 3D model of the measured gear was built based on the OpenGL graphics library. The models of the three-dimensional measuring platform and the laser tracker were built by using 3DSMAX and then they were imported into the simulation system. The touch detection between the probe and the measured gear was carried out using the Axis Aligned Bounding Box（AABB） method. The simulation system could communicate with the Renishaw＇ s UCC2 controller, reading out the real-time coordinate value to update the status of the three-dimensional measuring platform model in the simulation system. Results show that the system ran stably, super-large gear measuring simulation and touch detection between the probe and the gear is realized.
