免棱镜全站仪在建筑立面测绘中的应用研究

Application research on method of building elevation surveying and mapping using non-prism total station

针对常规建筑立面测绘方法作业强度大,不适于大规模建筑立面测绘的难题,提出了一种基于免棱镜全站仪的建筑立面测绘方法,该方法可以根据现场情况自由设站,构建独立坐标系,只需采集必要的点、线特征数据即可,数据采集后经过坐标变换与处理即可得到建筑平面及各个立面的正射投影数据并实现统一展点与绘制,可显著提升数据可视化效果以及作业效率,并从实践上验证了该方法在建筑立面测绘工作中的优越性和适用性。

Because the conventional method of building elevation surveying and mapping had some shortcomings such as needing more measurement personnel,higher labor intensity while lower efficiency,was not suitable for the large-scale elevation surveying and mapping. A new method based on non-prism total station was presented in this paper,the method only needed one observer and one non prism total station,could freely set the control station according to the project actual situation and construct independent coordinate system,only needed collect necessary points and lines. The building plane and each facade of ortho projection data of the building elevation surveying and mapping can be obtained through coordinate transformation after data collection and processing. The operation efficiency and visualization can be significantly improved and the superiority and applicability of the method was verified through the practices.
