倾斜摄影测量技术在城区建筑物立面测量中的应用

针对全站仪结合激光测距方式采集立面图效率低、成本高、立面图难以构建的问题,该文提出采用无人机进行倾斜摄影,利用数据解算软件完成实景三维模型的构建,并基于模型采集立面图的作业方案。经过实验验证,基于无人机倾斜摄影技术的方法所绘制的建筑立面图精度已经符合要求,可以满足实际项目的需要。因此,该方法可以推广应用于各种建筑立面测量工作中,为项目生产带来更多的便利和效益。

In view of the problems of low efficiency,high cost and difficult construction of elevation map acquisition by total station combined with laser ranging,this paper proposed a scheme of using UAV for oblique photography,using data solving software to complete the construction of 3D real scene model,and collecting elevation map based on the model.The experiment verifies that the accuracy of the building elevation drawing based on the UAV oblique photography technology has met the requirements and can meet the needs of practical projects.Therefore,this method can be applied to all kinds of building facade measurement work,bringing more convenience and benefits to project production.
