Abstract 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.
