摘要
通过eBeePlus免像控无人机航空摄影测量系统应用于1∶500地形图测绘工程实例,探究其在实践中的制图精度及适用性。使用emotion3、Pix4dMapper等软件进行外业航飞、内业影像处理,对比分析RTK和PPK两种解算方式下的制图精度,两者均满足规范要求,PPK解算方式更适宜在实践中使用;结合Eps软件制作数字线划地图,对于影像中无法提取的房屋边线、植被覆盖区域地物,采取全野外调绘、实测进行补充,阐述了无人机航测与传统数字化测图相结合的作业方式。
In this paper,the eBeePlus image-free UAV aerial photogrammetry system is applied to 1∶500 topographic mapping project to explore its mapping accuracy and applicability in practice.Emotion 3 and Pix4dMapper are used to process the images of airlines and businesses in the field,and the mapping accuracy of RTK and PPK is compared and analyzed.Both of them meet the requirements of specifications,and PPK is more suitable for practical use.Combined with EPS software to make diqital line-drawing map,and for the features in the area Covered by Vegetation that could not be extracted from the image,the whole field mapping and field measurement were adopted to supplement.The method of combining UAV aerial surveying with traditional digital surveying is expounded.
