摘要：

为了更好地挖掘无人机飞行轨迹数据中蕴含的有效信息，准确客观地基于轨迹数据对无人机飞行质量进行评价，提出一种融合卷积神经网络 (CNN) 和双向 (Bi-directional) 长短期记忆 (LSTM) 神经网络的 CNN-BiLSTM 网络模型。首先，利用 CNN 网络和 BiLSTM 网络分别获取飞行轨迹数据的局部卷积特征和时间特征。然后，将两种特征送入特征融合层，使用融合后的特征进行分类并获得评分标签。针对六个数据集的数值实验表明，模型不仅取得了较好的分类效果，而且具有很好的泛化能力。

Abstract:

In order to better mine the effective information contained in the UAV flight path data and evaluate the UAV flight quality accurately and objectively based on the trajectory data, a CNN-BiLSTM network model which integrates convolutional neural network (CNN) and bi-directional long short-term memory (LSTM) neural network is proposed. Firstly, CNN and BiLSTM are applied to obtain the local convolution feature and time feature of flight path data respectively, and then the two features are sent to the feature fusion layer, and the fused features are used to classify and get the rating label. The numerical experiments on six datasets show that the model not only achieves good classification results, but also has good generalization ability.

Key words: UAV quality evaluation, convolution neural network, bi-directional long short-term memory network
