摘　　要：针对房地一体无人机测绘精度和稳健性问题,提出了一种基于倾斜摄影的裸眼测图方法。该法运用倾斜摄影测量技术建立实景三维模型,利用南方CASS3D进行裸眼数字线划采集。实验结果表明,房产界址点平面测量中误差、边长限差和面积限差均满足房地一体测绘三级精度要求,其中平面测量中误差为0.052 m,非常接近0.050 m二级精度标准要求,边长测量中误差也接近二级精度标准。与传统测绘方法相比,裸眼测图可以大幅提高测图效率和便宜性,不仅可以避免入户测绘,还能够补充测图成果,是一种一测多得的测图方法,可广泛应用于较低等级的地籍房产测量。For the problem of the accuracy and robustness of unmanned aerial vehicle(UAV)mapping in integrated surveying and mapping of real estate,a method of naked eye mapping based on tilt photography was proposed.This method was based on tilt photogrammetry to establish a real scene three-dimensional(3D)model,and applied southern CASS3D to collect digital line graph by naked eye mapping.The experimental results showed that the house boundary point planar mean square error,edge length tolerance and area tolerance of the integrated surveying and mapping of real estate met the requirements of class 3 accuracy,among them the planar mean square error surveying was±0.052 m,which was very close to the class 2 requirement of±0.050 m of planar mean square error,and the edge length measurement was also close to the class 2 standard.Compared with traditional surveying and mapping methods,the naked eye mapping could greatly improve the efficiency and cheapness of surveying and mapping.It could not only avoid household surveying and mapping,but also supplement surveying and mapping results.It is a surveying and mapping method that gets more from one survey and could be widely used in real estate surveying for lower grades.
