| 摘 要： | 针对机场噪声的特征及分布特点，提出了一种基于路径栅格的机场噪声等值线追踪算法。通过构造有效网格、建立具有顶点和的路径栅格，在等值线追踪过程中唯一确定下一个等值点，能够快速生成等值线图，然后根据自身特点对等值线进行光滑，最后，为了方便查看不同区域的噪声影响情况，需要对等值线用不同的颜色进行填充处理。

| Abstract: | For airport noise characteristics and distribution, a tracking algorithm of airport noise contours based on path grid is presented. By constructing effective grid vertex and path grid, contour tracking process can determine the only next equivalent points, and quickly generate a contour map, then smooth contour according to its own characteristics. Finally, in order to check the influence of noise of different regions, it is necessary to fill the contour with different colors. |
