摘要
传统方法使用全站仪施测获取外立面效率低,而使用三维激光扫描技术点云数据量较大,曲面建筑外立面制作不易选取。利用多旋翼五镜头无人机倾斜摄影测量获取吉林建筑大学所有建筑单体影像数据,利用DPModeler建立三维模型并快速获取建筑单体外立面线划图,通过多个特征点采样和图上量测比较的方法进行精度评定。结果可靠,操作性强,可满足工程要求。
The traditional method to obtain the external facade is to use the total station to measure, and the efficiency is low. The use of three-dimensional laser scanning technology for measurement. The amount of point cloud data is relatively large, the surface of the surface of the surface of the building is not easy to be selected. This paper uses multi rotor UAV five lens Jilin Architectural University all single buildings tilt photogrammetry to obtain image data, we use DPModeler to build 3D model and quick access to building facades DLG, through multiple feature points sampling and map measurement methods are compared for accuracy evaluation.The experiment proves that the results are reliable and operational, and meet the engineering requirements.
