摘要
面向生态保护红线勘界定标工作环节,本文针对生态保护红线区域多位于人迹罕至、山高林密区域的情况,开展了多源多尺度影像融合建模研究,解决了二维矢量数据与实景三维模型场景的融合问题,以此构建实景三维模型工作底图,辅助红线边界校核,并考虑边界所在区域微地形特征,实现科学选取标识点位,进而提升工作效率。
Aiming at the work of ecological protection red line demarcation and calibration,this paper conducts multi-source and multi-scale image fusion modeling research for the ecological protection red line areas that are mostly located in inaccessible,high mountains and dense forest areas,and solves the problem between two-dimensional vector data and real three-dimensional model scenes.To solve the problem of fusion,build a working base map of the 3 D real scene model,assist the red line boundary check,and consider the micro-topographic characteristics of the area where the boundary is located,so as to realize the scientific selection of marking points and improve work efficiency.
