Abstract：The unified registration of real estate is of great importance in our country at present. How to acquire rural housing land information rapidly and reliably is the most critical part. Unmanned Aerial Vehicle (UAV) low-altitude remote sensing (RS) has many advantages such as high flexibility and high time efficiency, which make it applicable for data acquisition. Thus, we propose a rapid and reliable workflow for rural housing land data acquisition based on UAV low-altitude RS technology and our experiments. Four main steps are included: the preparation, field data acquisition, image processing, and rural housing land information extraction. Meanwhile, a comparison with traditional method is conducted, through which the advantages of high-efficiency and low-cost of our workflow in data acquisition can be concluded. The workflow we proposed based on our research has good application prospect in rural housing land information acquisition, and can greatly improve the execution of real estate unified registration.
