基于全站仪自由设站的建筑立面测绘方法研究及应用

Research and Application of Building Elevation Surveying Based on Total Station with Free Station Method

针对建筑立面测绘,提出了一种基于全站仪自由设站的测绘方法。采用全站仪自由设站,建立自定义坐标系对建筑各立面进行直接测量,通过对投影变形的后处理,获得无变形的立面图。利用建筑物特征点或粘贴反射片作为公共联结点,实现多个自由测站数据的精确拼接,完成了复杂条件下的建筑立面测绘。该方法可省去建立地面控制网的过程,实现单人立面测绘作业,大大节省了人力,提高了效率,并通过大量的实践验证了其精度和适用性。

Aiming at building elevation surveying,a method based on total station free station is proposed.The total station is adopted to set up the station freely and establish a custom coordinate system for direct measurement of each facade of the building.Through the post-treatment of projection deformation,the elevation without deformation is obtained.By using the characteristic points of the building or pasting the reflector as the joint node.The data of several free stations can be accurately spliced.Building elevation surveying under complex conditions is realized.This method can eliminate the process of building ground control network and realize the surveying by single person.The manpower is greatly saved and the efficiency is improved.Its accuracy and applicability have been verified by a lot of practice.
