免像控无人机在竣工测量中的辅助应用

现如今,免像控无人机摄影测量技术发展迅猛,因其高效快速、安全、操作便捷及成本低等优势得到越来越多测绘单位的喜爱。该文以武汉某还建住宅小区为研究对象,测区内超高层建筑数量多,树木密集,通视条件差,且传统测量模式外业耗费时间长,人力物力消耗大。故采用将免像控无人机摄影测量技术与传统测量模式进行融合的作业方法,完成该项目的竣工测量。经精度评定,发现成果数据质量满足相关规范要求。

Nowadays, the photogrammetry technology of image-free UAV is developing rapidly, and it has been loved by more and more surveying and mapping units because of its advantages such as high efficiency, high speed, safety, convenient operation and low cost. This paper takes a residential district in Wuhan as the research object, the number of super high-rise buildings in the survey area is large, the trees are dense, the visibility condition is poor, and the traditional measurement mode takes a long time to work and consumes a lot of manpower and material resources. Therefore, the completion survey of the project is completed by combining the photogrammetry technology of image-free UAV with the traditional measurement mode. After the accuracy evaluation, it is found that the quality of the result data meets the requirements of the relevant specifications.
