摘　　要：针对测量机器人在自动搜索、识别、跟踪和精确照准合作棱镜时,由于目标棱镜的灵活性和对中杆气泡难以居中等影响实际测量点位精度的问题,提出一种球心拟合点位坐标的方法,并建立模型,采用编程计算和现场试验的方法进行了试验研究。结果表明,模型最大拟合相对误差为优于1×10-4 mm,该方法可在一定的距离内对中杆水准气泡不严格居中情况下得到正确的点位坐标,能够在提高效率的同时满足现代化工程建设和自动化变形监测系统对高精度数据获取的需求。For measuring robot during automatic search,identification,tracking and accurate sighting cooperation prism,target prism because of the flexibility of the pole and the bubble is centered and so difficult to affect the actual measurement point accuracy problem,a ball center point fitting coordinates methodologies and models used to calculate the programming and field test methods were studied.The results show that the maximum relative error fitting model is better than 1×10^（-4） mm,this method can be internal to a certain distance in the rod leveling bubble without strict centered properly point coordinates,to improve efficiency at the same time satisfy the modern engineering construction and the automatic deformation monitoring system for high precision data acquisition requirements.
