无人机辅助工程测图的应用

通过工程实践,依据无人机航拍成图的特点、产品特征,结合传统数字化测图的方法,通过利用GlobalMapper、Auto CAD等软件,进行数据转换、点云生成、点云参照、光栅图像叠加等,寻求了一种将无人机航拍和传统数字化测图相结合,并且适合传统工程测量人员容易掌握的高效测图方法;同时指出了无人机测绘及其辅助工程测图存在问题,以便在实践中得以解决和优化。

Application of UAV aided engineering mapping

Based on UAV aerial mapping characteristics and its product features combined with the traditional methods of digital mapping,an efficient mapping method combining UAV aerial photography with traditional digital mapping,which is also suitable for use by traditional engineering surveyors,was developed through the use of GlobalMapper,AutoCAD and other softwares to perform data transformation,point-cloud genera-tion,point-cloud reference and raster image superposition,etc.At the same time,some issues associated with using the UAV surveying method combined with engineering mapping were raised so as to explore ways to solve the problems and optimize the process in practice.
