The invention provides a driver emotion recognition method, system and device and a medium, and belongs to the technical field of driver emotion monitoring, and the method comprises the following steps: obtaining historical data of facial expression features, physiological features and driving behavior features of a driver, and clustering the historical data to obtain a clustering result; dividing the driving styles of the drivers into different categories according to a clustering result; inputting the clustering result data corresponding to the different driving style categories into a neural network model, and training the neural network model to obtain emotion recognition models corresponding to the different driving style categories; judging an emotion recognition model corresponding to the driving style category of the driver needing emotion recognition, and recognizing emotion state data of the driver in different time windows according to the corresponding emotion recognition model; and setting an emotion recognition threshold, and judging the emotion state of the driver according to the emotion state data greater than the emotion recognition threshold in each time window. The accuracy of driver emotion recognition can be improved.

    本发明提供了一种驾驶员情绪识别方法、系统、设备及介质,属于驾驶员情绪监测技术领域,其方法包括如下步骤:获取驾驶员的面部表情特征、生理特征及驾驶行为特征的历史数据,对历史数据进行聚类,根据聚类结果将驾驶员的驾驶风格划分为不同类别;将不同的驾驶风格类别所对应的聚类结果数据输入神经网络模型,对神经网络模型进行训练,得到不同的驾驶风格类别对应的情绪识别模型;判定需要进行情绪识别的驾驶员的驾驶风格类别对应的情绪识别模型,根据对应的情绪识别模型识别驾驶员在不同时间窗口的情绪状态数据;设定情绪识别阈值,根据每个时间窗口内大于情绪识别阈值的情绪状态数据判定驾驶员的情绪状态。本发明能够提高驾驶员情绪识别的准确性。
