Abstract: With the increasing requirements of real estate registration and management, there are higher requirements for the current, accuracy and timeliness of real estate data. With a long period and large input of manpower and material resources, obtaining real estate data through detail surveying and indoor mapping by using total station and RTK is difficult to meet the needs of modern management. Surveying and mapping 1:500 topographic map through UAV tilt photogrammetry technology can not only meet the requirements of real estate surveying and mapping data accuracy, but also solve the real estate registration well with its characteristics of fast, convenient, flexible and rich achievements. The tests show that the application of key technology is relatively mature and has obvious benefit. It has good popularization and application value.

Key words: UAV, tilt photogrammetry, 3D model, real estate registration, revisal surveying and mapping
