摘　　要：讨论基于高精度免棱镜测量技术确定圆管轴线点的测量方法和数据处理方法。采用模拟数据计算比较基于几何距离和基于代数距离对不同椭圆扫描范围的中心点确定结果,并通过实际测量结果验证该方法的可行性和高效性。The surveying technique and data processing method for axis determination of round normal section based on reflectorless distance measurement are discussed.A new train of though that is the calculation and comparison of the determined results from the simulative data of the center point of different elliptically scanning range based on geometric and algebraic distance is presented.Simulation and practical results show its feasibility and high efficiency.
