倾斜摄影测量技术在房地一体测绘中的应用

Application of Tilt Photogrammetry Technology in Integrated Surveying and Mapping of Premises and Buildings

为解决农村房屋测量的低效率、高成本和长耗时问题,该文采用无人机倾斜摄影测量技术进行房产精准测绘。首先利用无人机倾斜摄影获取不同角度的影像,构建实景三维模型,然后在三维模型上利用CASS3D软件进行内业数据采集,得到房地一体地图成果。通过检查点和界址线的中误差对倾斜摄影成果进行精度分析,结果表明,无人机倾斜摄影测量技术可以完全满足技术规范,数据成果精度高,有效地提高工作效率与质量,缩短项目生产周期。

To solve the problems of inefficiency,high cost and long time-consuming in rural house measurement,this paper uses UAV tilt photogrammetry technology to accurately survey real estate.First,UAV tilt photography is used to obtain images from different angles,and a real-life three-dimensional model is built.Then,CASS3D software is used to collect indoor data on the three-dimensional model,and the results of the integrated map of the premises and buildings are obtained.The accuracy of tilt photography results is analyzed through the medium errors of checkpoints and boundary lines.The results show that the UAV tilt photogrammetry technology can fully meet the technical specifications,and the data results have high accuracy,effectively improve work efficiency and quality,and shorten the project production cycle.
