倾斜摄影技术的单体塔式建筑物三维重建方法

针对塔式单体建筑物形状不规则导致三维模型构建失败，提出倾斜摄影技术的塔式单体建筑物三维重建方法. 选用消费型多旋翼无人机搭载单镜头的相机，通过环线拍摄的方式获取多视影像数据，通过ContextCapture软件对获取的多视影像数据进行处理，构建塔式建筑物的实景三维模型，利用外业控制点、纹理细节信息对生成的三维模型精度评定. 试验表明:环线航拍获取多视影像数据构建三维模型，精度较高、模型纹理信息缺失少、完整度高. 

3D reconstruction method of single tower building based on tilt photography

Aiming at the failure of building three-dimensional model due to irregular shape of single tower building, a three-dimensional reconstruction method of tower single building based on inclined photography technology is proposed. First, the consumption type multi rotor unmanned aerial vehicle equipped with a single lens camera is selected to obtain the number of multi view images by loop shooting. Then, the multi view image data is processed by ContextCapture software to construct the real three-dimensional model of tower building. Finally, the accuracy of the generated three-dimensional model is evaluated by using the field control points and texture details. The experiment shows that; the loop line aerial photography used to obtains the multi view image data to construct the three-dimensional model has high accuracy, less missing texture information and high integrity.
