基于倾斜摄影模型提取1∶500地形图要素技术研究及应用

Technology Research and Application of Topographic Map Elements of 1 ∶ 500 Are Extracted Based on Oblique Photography Model

基于探索无人机倾斜摄影技术在工程测量领域的生产及推广应用,采用绘图平台程序结构优化及功能模块定制,实现在倾斜摄影三维实景模型中提取地形图要素技术方法,通过成果数据比对分析满足1∶500地形图相关精度要求,形成了较完整的技术流程体系,可为倾斜摄影技术应用于大比例尺地形图测绘提供一定的参考,同时提出了该技术的应用展望。

Based on the exploration of production,application and promotion of UAV tilt imaging technology in engineering surveying,the program structure optimization and function module customization of the mapping platform are adopted to realize the technology of extracting topographic features in the oblique photographic three-dimensional real scene model. Through the comparison of results data to meet the 1： 500 topographic map related to the accuracy requirements,this formation process a more complete technical system. It can provide a reference for the application of oblique photography in large-scale topographic mapping,and put forward the prospect of this technology.
