双相机倾斜摄影在建筑物要素摸查中的应用
|
摘要
基于对大范围城市建筑物要素进行快速摸查的目的,分析了双相机倾斜摄影无人机飞行系统的构成和主要优势,进而研究了双相机倾斜摄影在城市建筑物要素摸查应用的关键技术及工作流程,通过对广州市黄埔区某测区进行实验,证明了双相机倾斜摄影技术能够快速获取全面的建筑物要素信息,相比传统的五相机系统具有构建模型精度高、相同地面分辨率下航高值可选范围大的优势,在城市建筑物要素摸查中具有良好的可行性和广阔的应用前景。最后,通过分析该技术在应用过程中的主要局限,为后续研究指明了方向。
Based on the purpose of rapid exploration of large-scale urban building elements,this paper analyzed the composition and main advantages of the flight system of the dual-camera tilt photography UAV,and then studied the key technology and working process of the application of the dual-camera tilt photography in the exploration of urban building elements.Experiments showed that the dual cameras tilt photography technology can quickly obtain comprehensive information of building elements.Compared with the traditional five camera system,the system has the advantages of high precision of building model and large optional range of altitude values under the same ground resolution.It has good feasibility and wide application in the urban building elements exploration.Finally,the main limitations of the technology in the application process were analyzed,and the direction for further research was pointed out.
