According to the goal put forward by the Ministry of natural resources in 2020 “notice on accelerating the registration of the use right of homestead and collective construction land”, China must basically complete the data integration and exchange of rural cadastral survey and real estate registration results of counties and districts before the end of 2021. At the same time, the Ministry of natural resources has made clear the principle of “integration of real estate and land”, requiring the above ground buildings and structures such as rural houses to be included in the scope of registration and certification of the use right of homestead and collective construction land. Some provinces that have made rapid progress have determined the completion point. For example, Guangdong Province has listed the rural housing and land integration registration as one of the key natural resources in Guangdong Province in 2020, which clearly requires that it should be basically completed by 2020. In addition, Yunnan Province also requires that 90% of the rural real estate ownership registration and certification work be completed by the end of 2020.

The era of "integration of real estate and real estate" has come, and a new breakthrough of UAV aerial reconnaissance has been made

The era of “integration of real estate and real estate” has come.

In the process of rural real estate registration, the most time-consuming technology is field data collection. The conventional measurement method mainly adopts the whole field data acquisition mode of gnss-rtk and total station. Although this mode has high precision and less omission, it needs a lot of outdoor measurement, heavy task, long cycle and high cost, which does not have any advantages in scattered villages.

In contrast, UAV three-dimensional tilt photogrammetry technology has made it possible to quickly and efficiently collect field data. Through the non-contact measurement, the difficulty of entering the family in the measurement of residential base is avoided, and most of the work is transferred to the internal processing, which reduces about 90% of the external work, and finally saves the labor and time cost.

Since the beginning of this year, the vast majority of UAV manufacturers have been promoting their own UAV tilt photogrammetry scheme for the “real estate integration” project. At present, the accuracy of UAV tilt photography has been better than 5cm, which can completely replace the traditional surveying and mapping means, especially the multi rotor UAV for tilt photogrammetry, which is very suitable for the development of the “integration of real estate” project. Optimistic estimate, this year aerial survey UAV market will usher in a round of explosive growth.

In addition to improving the efficiency, the man-machine tilt photogrammetry method also has the advantages of visual intuition. The model effect is consistent with that of the field. For example, temporary buildings can be directly identified, the number of floors of houses can be directly counted, and the affiliated buildings can be directly distinguished. The requirements for interior operators are low, and they can participate in production after simple training, and there are also advantages of DOM and inclined 3D model and other by-products.
