Airspace Real-time Flow Monitoring Based on Improved Watershed Algorithm

为缓解空中交通拥挤和拥堵现状,提高空域资源利用效率和航空器运行效率,需对空域流量进行实时监测与告警,在已有研究基础上提出改进分水岭算法的空域流量监测模型。首先对分水岭算法中的距离操作算子进行改进,其次结合航路航线与尾流间隔要求进行约束条件构建;最后选取西南贵州地区某一空域进行算法仿真,并对改进前后的空域流量监测结果进行分析说明,实验结果表明:基于传统分水岭算法的空域流量监测准确率为93.5%,改进后的监测准确率为100%,证明改进分水岭算法在空域流量监测方面是合理高效的。

In order to alleviate the current situation of air traffic congestion and congestion,improve the efficiency of airspace resource utilization and aircraft operation efficiency,it is necessary to conduct real-time monitoring and warning of airspace flow.On the basis of existing research,an airspace flow monitoring model with improved watershed algorithm is proposed.Firstly,the dis⁃tance operator in the watershed algorithm is improved,and then the constraints are constructed in combination with the air route and wake interval requirements.The results are analyzed and explained.The experimental results show that the accuracy of airspace flow monitoring based on the traditional watershed algorithm is 93.5%,and the improved monitoring accuracy is 100%,which proves that the improved watershed algorithm is reasonable and efficient in airspace flow monitoring.
