Research on the application of real-scene 3D modeling based on least squares method in boundary surveying and mapping
This paper based on the oblique photogrammetry and real-scene 3D modeling technology,introduces a technique to construct TIN(Triangulated Irregular Network)and real-scene 3D models by utilizing remote sensing images,land use status survey,and land ownership survey data.Through the application of Least Squares Method,real-time measurement,and application of data model fusion,it provides more comprehensive and accurate data support for geospatial information analysis.Taking the administrative division adjustment of Longgang City as the research object,this article discusses the key technical difficulties and processes of surveying and mapping the administrative boundaries,and provides a new solution for the surveying and positioning of boundary points and ownership dispute points of administrative regions.The research results of this article effectively improve the efficiency and quality of boundary surveying and mapping work,greatly reduce human costs and work cycles,and provide strong technical support and theoretical references for the comprehensive utilization of natural resources and the management of administrative regions.
