A accurate measurement method of laser total stations based on vision gui dance

In order to improve the measurement efficiency and measurement accurac y,a laser total station measurement system based on vision guidance is proposed.The measurement system consists of a non-orthogonal laser total station and a zoom camera.This paper firstly introduces the structure design of the measurement system,followed by the analysis of measurem ent method of non-orthogonal laser total station and precise guiding strategy,finally stabil ity and accuracy of the measurement system is verified through real experiment.The experiment shows tha t the method is simple and effective,improves the measurement efficiency,and has a measurement accuracy of millimeters,which demonstrates proposed measurement system has high practical v alue in large space measurement of tunnels,buildings and so on.
