无人机倾斜摄影测量技术用于农房不动产测绘

Application of Tilt Photogrammetry Technology of UAV in Rural Real Estate Project

结合实际项目案例,介绍了在农房不动产测绘项目中运用无人机倾斜摄影测量技术获取高精度三维模型,绘制权籍图的方法。通过与实地测量数据进行精度对比分析获取试验结果,结果表明该技术能满足1∶500大比例尺权籍图精度要求,同时也为农房不动产测绘项目提供了一条高效的作业模式,大幅降低了外业工作强度,提高了作业效率。

Combined with the actual project case,this paper introduces the method of obtaining high-precision three-dimensional model and drawing cadastral map by using UAV tilt photogrammetry technology in the surveying and mapping project of rural real estate.Through the precision comparison and analysis with the field measurement data,the test results show that the technology can meet the accuracy requirements of 1∶500 large-scale cadastral map.At the same time,it also provides an efficient operation mode for the rural real estate surveying and mapping project,greatly reduces the field work intensity and improves the operation efficiency.
