Application of UAV Tilt Photography in Cadastral Survey

无人机倾斜摄影测量作为一种测绘地理信息行业中的一项新型技术，具有效率高、受环境因素制约小等优点。借助该方法的优势，开展地籍调查工作，并进行精度检验，界址点中误差为3 cm，粗差率为3.92%，界址边长中误差为2.8 cm，粗差率为3%。结果表明，无人机倾斜摄影的方法可以较好地应用于平原地区的地籍调查中，满足精度的基本要求。As a new technology in the surveying and mapping geographic information industry, UAV tilt photogrammetry has the advantages of high efficiency and is less restricted by environmental factors. The cadastral survey was carried out with the advantages of this method. After accuracy check, the mean square error of boundary points was 3 cm and the gross error rate was 3.92%, the mean square error of boundary length was 2.8 cm and the gross error rate was 3%. The results showed that the method of UAV tilt photography can be better applied to the cadastral survey in plain areas, and meet the basic requirements of accuracy.
