摘　　要：提出一种基于云平台与眼动注视点数据的航空器4D航迹跟踪算法,实时跟踪航空器航迹,及时发现和纠正潜在安全隐患,减少飞行事故的发生。借助云平台构建航空器4D航迹跟踪架构,架构中包含数据采集、传输、存储、处理以及应用服务5个层次。利用采集层中的红外摄像机和传感器采集飞行员眼动数据和航空器飞行数据;利用传输层将这些数据通过无线传输的方式输送至存储层中的云存储区;在数据处理层中对多信息源的航空器飞行数据实施融合处理;在应用服务层中通过瞳孔定位、注视点标定操作获取飞行员注视点的轨迹信息,将其作为航空器4D航迹跟踪的重要补充信息;构建基于深度神经网络的航空器4D航迹预测模型,将经过融合的航空器飞行数据以及飞行员注视点轨迹信息作为模型的输入量,模型的输出结果即为航空器4D航迹预测结果;利用马氏距离将预测结果与预设航线实施对比,依据对比结果调整航空器的控制参数,实现4D航迹跟踪。实验结果表明,该方法可以精确跟踪航空器4D航迹,在微分平整度方面有着较好的表现。A 4D aircraft track tracking algorithm based on cloud platform and eye movement fixation point data is proposed to track aircraft tracks in real time,detect and correct potential safety hazards in time,and reduce the occurrence of flight accidents.The 4D aircraft track tracking architecture is built with the help of cloud platform,which includes five levels of data acquisition,transmission,storage,processing and application services.Infrared cameras and sensors in the acquisition layer are used to collect pilot eye movement data and aircraft flight data.Using the transport layer,these data are transmitted wirelessly to the cloud storage area in the storage layer.In the data processing layer,the aircraft flight data with multiple information sources is integrated.In the application service layer,the trajectory information of the pilot’s fixation point is obtained through the operation of pupil positioning and fixation point calibration,and it is regarded as the important supplementary information of aircraft 4D track tracking.A 4D flight path prediction model of aircraft based on deep neural network is constructed.The integrated flight data of aircraft and the pilot’s gaze point trajectory information are taken as the input of the model,and the output result of the model is the 4D flight path prediction result of aircraft.Markov distance is used to compare the forecast results with the preset route,and the control parameters of the aircraft are adjusted according to the comparison results to realize the 4D track tracking.Experimental results show that this method can track aircraft 4D track accurately and has a good performance in differential flatness.
