民航轨迹数据存在采样时间不均匀、空间维度量纲不一致的问题,并且现有轨迹预测方法主要面向行人、车辆等地面交通轨迹,适用于三维空间中的民航轨迹预测方法较少。针对上述问题,提出一种基于生成式对抗网络的三维空间民航轨迹预测模型。该模型对民航轨迹数据重采样以统一采样间隔,消除不同量纲影响;使用数据中的时序特征和不同目标之间的交互信息生成预测轨迹。实验表明,与传统轨迹预测方法相比,该模型在ADE指标上降低了 29%以上,验证了模型在三维空间民航轨迹预测中的有效性。
3D FLIGHT TRAJECTORY PREDICTION MODEL BASED ON GENERATIVE ADVERSARIAL NETWORK
Flight trajectory data has the problems of uneven sampling time and inconsistent spatial dimension.Moreover,the existing trajectory prediction methods are mainly oriented to ground traffic trajectory such as pedestrians and vehicles,and there are few flight trajectory prediction methods applicable to three-dimensional space.To address the above problems,this paper proposes a prediction model for 3D flight trajectory based on generative adversarial network.The model resampled the flight trajectory data to unify the sampling time interval and eliminate the influence of extreme variation between different spatial dimension.The time series characteristics in the data and the interaction information between different targets were used to generate the predicted trajectory.Experiments show that compared with traditional trajectory prediction methods,the proposed model reduces the ADE by more than 29%,which verifies the effectiveness of the model in the prediction of flight trajectory in 3D space.
