三维场景重建中无人机飞行拍摄路径快速计算技术

Scene photographing based on unmanned aerial vehicle (UAV) with multi-cameras equipment has been widely used in the rapid reconstruction of 3D scene. The existing UAV with multi-cameras scene flight path planning method usually do not consider the relationship between the various scene geometry and its reconstruction based on flight path planning is relatively simple, often causing scenes of incomplete data collection or redundancy, reduce the efficiency of data collection, has seriously affected the quality and efficiency of 3D scene reconstruction. This project proposes a method based on UAV with multi-camera equipment to full coverage and high resolution scene area photographing for the complex scene of the city or the factory buildings, that is, proposes a rapid construction technology of scene geometry structure for complex scene area, to provide a technical condition for improving scene data collection efficiency, provides a new method for the rapid reconstruction of three-dimensional scene acquisition in complex scenes. The results of this project have a good application in many fields such as national defense, public security and smart city.

基于无人机多相机设备进行场景拍摄已广泛应用于三维场景快速重建过程中。现有的基于无人机多相机场景拍摄飞行路径规划方法通常不考虑场景建筑等各种场景几何结构关系，飞行路径规划相对简单，经常造成场景数据采集不全或者冗余等问题，降低了数据采集的效率，严重影响了三维场景重建的质量和效率。本项目针对无人机多相机设备提出一种对城市或工厂等建筑密集复杂场景区域的全覆盖和高分辨率拍摄的场景几何快速重建方法，研究基于多相机运动的复杂场景区域的场景几何结构快速构建技术，为提高场景数据的采集效率提供技术基础，为三维复杂场景快速重建提供一种新的场景采集方法。本项目成果在国防军事、公共安全和智慧城市等领域具有良好应用前景。
