无人机测量技术在实景三维建模中的应用

Application of UAV Measurement Technology in Real Scene 3D Modeling

推动无人机倾斜摄影测量技术的发展对满足实景三维建模要求及市场需求具有重要意义。本研究以某科创园为研究对象,结合无人机对其进行倾斜摄影测量,使用GPS-RTK对像控点进行测量,将无人机拍摄的相片导入ContextCapture软件中,进行内业空三加密、三维模型重建。在此基础上,提供对比模型上的坐标和实地检测点来检测模型质量。试验结果表明:无人机测量技术具有更加明显的优势,能够快速准确地获取影像信息,符合未来发展需要,具有广阔的市场前景。

It is of great significance to promote the development of UAV tilt photogrammetry technology to meet the requirements of real three-dimensional modeling and market demand.In this study,a science and technology park is taken as the research object.Combined with UAV,the oblique photogrammetry is carried out,and the GPS-RTK is used to measure the image control point.The photos taken by UAV are imported into ContextCapture software for indoor aerial triangulation encryption and 3D model reconstruction.On this basis,the coordinates and field detection points on the comparison model are provided to detect the model quality.The experimental results show that UAV measurement technology has more obvious advantages,can quickly and accurately obtain image information,meet the needs of future development,and has broad market prospects.
