建筑摄影测量系统及其应用案例

Architectural Photogrammetry System and Application Case

将摄影测量技术与无人直升机平台结合,可以消除"地面拍摄"这一瓶颈,在建筑领域更好地发挥摄影测量低成本、高效率的优势。紫竹林教堂是天津现存最古老的教堂,因该教堂的沉降、变形情况复杂,测绘难度高,所以使用"建筑摄影测量系统"对该建筑进行测绘。这是国内使用这一新技术对古建筑室内外进行整体测绘的第一个实例。通过对作业过程的分析、总结,归纳出建筑摄影测量系统的使用方法、作业流程,同时还介绍了该系统的主要构架,并简述研发历程以及将来的主要发展方向。

Combining photogrammetry with unmanned helicopter vehicle is the best way to lift the camera position and get aerial photographs for ancient buildings.After 4 years of research,the author established the'Architectural Photogrammetry System(APS )'by overcoming many technical difficulties.APS can survey almost all kinds of buildings independently.The main components of APS will be presented in this article,and also the R&D process,the main development direction of the future. Zi Zhu-lin is the oldest church in Tianjin city.Author surveyed the whole church building by using Architectural Photogrammetry System recently.This is the first case in China that mapping a building by using photogrammetry technology independently.It's also the first time that the unmanned helicopter vehicle doing contactless surveying work for a risky building in populated civic centre.Moreover,Zi Zhu-lin is the building which with the most complicated deformation and subsidence the author ever treated with.So it's a typical project feasible for testing performance of the new mapping system.The operation procedure of this brand new APS can be obtained through summing up what we have learned in this case.
