摘要
为实现实景和三维空间信息模型的融合和精细化表达,文中以陕西理工大学南校区为例,基于二、三维矢量数据、实景模型和纹理贴图,借助MapGIS三维平台和精细建模工具,将室内和室外三维场景表达和功能展示结合,实现了校园构筑物三维空间信息模型和实景的精细化模型表达。三维空间信息模型根据语义环境,可自适应性地建立三维构筑物表面纹理、色调、分辨率等表达,也可在三维GIS(Geographic Information System)功能基础上,实现可视域分析、表面分析、粒子效果、天际线分析等功能。
In order to achieve the fusion and refined model expression of the real scene and the three-dimensional spatial information model,the South Campus of Shanxi University of Technology was applied to modelling the three-dimensional scene based on the two and three-dimensional vector data,the real scene and texture.Both Map GIS three-dimensional platform and fine modeling tools,realized the indoor and outdoor three-dimensional scene expression and function display,and achieved the refined model expression of the three-dimensional spatial information model and real scene of the campus structure.The 3D spatial information model could adaptively establish the surface texture,hue,resolution and other expressions of 3D structures according to the semantic environment,and could also implement visual field analysis,surface analysis,particle effect,and skyline analysis based on the 3D-GIS function.
