The invention discloses a flight prohibition zoning method based on coordinate sorting Grahama-scan. The flight prohibition zoning method comprises the following steps: 1, acquiring environmental dataof a target area to be divided; 2, constructing a coordinate sorting model according to the environmental data acquired in the step 1, and performing data screening; and 3, on the basis of establishing coordinate sorting, carrying out dangerous zone division by utilizing a Graham-scan algorithm. According to the meteorological radar echo intensity data, a large amount of uncontributed data is eliminated through coordinate sorting in combination with a Graham-scan algorithm, the number of ray angle values obtained through a space scanning method is reduced, and the speed of setting a flight limited area is increased.
本发明公开了一种基于坐标排序Graham‑scan的飞行禁止区划设方法,步骤一:采集所要划分的目标区域的环境数据;步骤二:根据步骤一采集的环境数据,构建坐标排序模型,进行数据筛选;步骤三:在建立了坐标排序的基础上,利用Graham‑scan算法进行危险区划设。本发明根据气象雷达回波强度数据,通过坐标排序结合Graham‑scan算法,剔除大量无贡献数据,减少空间扫描法获取射线角度值数量,加快了划设飞行受限区速率。
