Application Research on Real Estate Surveying Based on Combination of Oblique Photography and LiDAR |

| Abstract: | Real estate cadastral surveying is a basic surveying and mapping work.The sound development of cadastral surveying techniques and methods can not only maximize the land utilization rate in my country,but also provide efficient and convenient means for obtaining high-precision spatial data.The combination of station instrument and GPS-RTK has the disadvantages of low efficiency and high cost of human and financial resources.Based on a cadastral and real estate survey project in southern Shanxi,we proposed a new plan based on combination of ground 3D laser scanning technology and oblique photography technology.The combination of two technologies can greatly improve work efficiency(data acquisition speed is more than 4 times the traditional operation speed)and data collection accuracy(the boundary point error is less than 3 cm),and meet the real estate property management and registration requirements for complex space rights. |
