摘  要:伴随我国机场的改扩建与数量的增加,机场噪声问题也日渐突出,进行机场噪声的可视化成为治理机场噪声的重要部分。文章针对机场噪声可视化中出现的问题,提出基于开源框架Cesium进行机场噪声的三维热力图可视化,探讨了坐标转换以及三维热力图的实现原理与方法。通过将实测数据进行数据预处理并在Cesium框架中进行调用,最终实现了机场噪声的三维热力图可视化,验证了技术与方法的可行性,丰富了机场噪声的可视化效果,采用渐变过渡的可视化方法来消除噪声数据的数值界限,减小了算时的误差,使可视化效果更加逼真。为职能部门优化飞行程序,合理规划空间以及进行有效的降噪工作提供了科学依据。With the reconstruction and expansion of airports in China and the increase in the number,the problem of airport noise has become increasingly prominent.Visualizing airport noise has become an important part of managing airport noise.This paper proposes a 3D heat map visualization of airport noise based on the open-source framework Cesium,addressing the issues that arise in the visualization of airport noise.It explores the coordinate transformation and the principles and methods of the implementation of 3D heat map.By preprocessing the measured data and calling them in the Cesium framework,a 3D heat map visualization of airport noise is finally achieved,verifying the feasibility of the technology and methods,enriching the visualization effect of airport noise.The gradual transition visualization method is used to eliminate the numerical boundaries of noise data,reducing computational errors,and making the visualization effect more realistic.This provides a scientific basis for functional departments to optimize flight procedures,plan space reasonably,and carry out effective noise reduction work.
