|
摘要
为了降低制造成本和提高测量效率,提出了基于视觉引导的激光全站仪测量系统。此系统由非正交激光全站仪和一台变焦相机组成。介绍了此系统的结构设计,分析了基于视觉的精确引导策略,最后通过与激光跟踪仪的对比测量实验,验证了该测量系统方法简单有效,并有毫米级的测量精度。在隧道、建筑与室内等空间测量方面有很高的实用价值。
In order to improve the measurement efficiency and measurement accuracy,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 measurement method of non-orthogonal laser total station and precise guiding strategy,finally stability and accuracy of the measurement system is verified through real experiment.The experiment shows that 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 value in large space measurement of tunnels,buildings and so on.
