Zheng Hua et al. (2018) by tiltphotographing 3D model mapping and traditional photogrammetry two mapping methods, proved that for the whole field measured topographic mapping methods, 3D model mapping in terms of efficiency and cost have obvious advantages, worthy of wide application.Jiang Jian et al. (2019) used tilt photography 3D modeling, using EPS software to collect terrain information for 3D mapping, and by selecting different types of terrain feature points as checkpoints on the topographic maps and 3D models produced by traditional manual measurement methods for precision analysis, the results showed that the measurement specification requirements were met.Zhang Wenchun et al. (2019) based on the image-free uavouring drone tilt photogrammetry of the real-life model naked eye 3D mapping study, the results show that this mapping model can be used for the production of 1:500 topographic map, for the mass production of topographic maps to provide a new way of thinking, for the accuracy of the map needs to be improved, need further research.Wan Yinqian (2019) uses the UAV tilt measurement technology to carry out the survey of cadastral, the results prove that the non-image control drone tilt photogrammetry technology can avoid all kinds of work and inconvenience steam edgy like control measurement, and can be applied to rural cadastral measurement, not only to ensure the accuracy of cadastral measurement, but also reduce the workload of the internal and external industry, the future extensive rural premises measurement has an important role to promote.Mo Wei (2020) proposed a new large-scale scale topographic mapping method, based on the UAV tilt photogrammetry to carry out large-scale topographic mapping, and proof of this method can meet the accuracy specification requirements of large-scale topographic map, and can effectively draw the near-earth objects blocked by the distant land, to ensure the integrity of the topographic map results, reduce the field mapping and retesting work.
