基于LOD1城市模型的噪声数据可视化

Noise data visualization based on LOD1 city model

近年来,噪声污染日益严重,已成为生态环境类投诉的主要内容。为更直观地查看和分析噪声污染,提升噪声治理和管控能力,本文基于城市信息模型(CIM)和噪声监测数据,结合数据叠加和三维渲染技术,研究大尺度三维噪声地图技术,实现了融合倾斜摄影和白膜噪声数据的三维可视化,在噪声污染监督和治理中,通过该技术的噪声可视化分析进行优化决策,可为智慧城市建设增添动力。

In recent years,noise pollution has become increasingly serious and has become the main content of ecological and environmental complaints.In order to more intuitively view and analyze noise pollution,improve noise control and management capabilities,this article is based on urban information modeling(CIM)and noise monitoring data,combined with data superposition and 3D rendering technology,to study large-scale 3D noise map technology,and achieve 3D visualization by integrating oblique photography and white film noise data.The aim is to optimize decision-making in noise pollution supervision and control through the noise visualization analysis of this technology,add momentum to the construction of smart cities.
