Statistical Research on Land Acquisition and Demolition Engineering Quantity Based on UAV Tilt Photogrammetry Technology
In order to solve the statistical problems of land acquisition and demolition in the early stage of the old city reconstruction project,based on the tilt photogrammetry technology,the UAV survey method is used to obtain the image data,and then the reconstruction of the 3D real scene model is realized through the steps of air-three encryption,image matching,triangle network establishment and texture mapping.Combined with the digital elevation model,positive photography,BIM(building information model)and other data,the 3D GIS(geographic information system)of the old city plot is constructed,the buffer area is analyzed,and the work amount of housing demolition is calculated.The feasibility and effectiveness of tilt photogrammetry technology in the application of land acquisition and demolition project is verified through an example of an old city renovation and construction project.
