摘要
本文基于倾斜摄影测量和实景三维建模技术,利用遥感影像、土地利用现状调查及土地权属调查等数据构建TIN(不规则三角网)和实景三维模型,通过最小二乘法算法、实时量测和数据模型融合应用,为地理空间信息分析提供了更为全面和精确的数据支持。以龙港市行政区划调整为研究对象,对行政区域界线测绘的关键技术难点和流程进行了探讨,并为行政区域界线边界点及权属争议点的测绘定位提供了全新的解决方案。本文的研究成果有效提高了界线测绘工作的效率和质量,大幅降低了人力成本和工作周期,为自然资源综合利用及行政区域管理工作提供了有力的技术支持和理论参考依据。
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.
