摘要
基于无人机测绘技术,文章进行了无人机地籍测绘及其精度分析。在精度方面,将无人机地籍测绘精度分为明显界址点测绘精度、隐蔽界址点测绘精度与地物点平面位置精度。通过对佛山某地区进行1∶500地籍图测绘,发现明显界址点精度达到二级要求,隐蔽界址点精度达到三级要求,总体上满足三级要求,地物点平面位置精度完全符合精度要求。通过精度稳定性评价,发现明显界址点和地物点精度稳定性达到84%,而隐蔽界址点精度稳定性只有75%,因此无人机地籍测绘存在一定的局限性,它仅适用于包含明显界址点区域的低等级地籍测绘,而不适用于隐蔽界址点较多区域的地籍测绘,目前无人机地籍测绘尚无法独立实施。
Based on UAV surveying and mapping technology,the UAV cadastral surveying and mapping and its accuracy analysis are carried out in this paper.In precision,the precision of UAV cadastral surveying and mapping was divided into obvious boundary point precision,concealed boundary point mapping accuracy and surface features accuracy.Through 1∶500 cadastral mapping in Foshan area,it is found that obvious boundary points accuracy reach two accuracy level requirements,hidden boundary points accuracy reach three level,on the whole,it meets the three level requirements,moreover,the location precision of surface features meets all accuracy requirements.Through precision stability evaluation,we found obvious boundary points and surface feature point accuracy stability reached 84%,while the concealed boundary point precision stability is only 75%,so the UAV cadastral survey and mapping has certain limitation,it applies only in contain obvious boundary point area with low grade,and is not suitable for more concealed boundary points area,at present,the UAV cadastral survey and mapping is not used without other survey means.
