The invention is suitable for the technical field of automobiles, and provides a state detection method, a vehicle-mounted terminal and a storage medium, and the method comprises the steps: obtaining the physiological data of a driver of a vehicle in the driving process of the vehicle; performing dynamic feature extraction processing on the physiological data to obtain feature data; the dynamic feature extraction processing refers to processing a historical data sequence of an input variable according to a set calculation mode; inputting the feature data into a trained state detection model for processing to obtain the state of the driver; the state detection model is obtained by training a pre-constructed time recurrent neural network. Compared with the prior art that the face features of the driver are detected through a vehicle-mounted camera to judge the state of the driver, the method has the advantages that more significant and representative information can be extracted through dynamic feature extraction, the dimension of data is reduced, the most important features in the data are reserved, and the reliability of the system is improved. Therefore, the detection accuracy and the detection precision of the state of the driver are improved.

    本申请适用于汽车技术领域,提供了一种状态检测方法、车载终端及存储介质,所述方法包括:在车辆行驶过程中,获取车辆的驾驶员的生理数据;对生理数据进行动态特征提取处理,得到特征数据;动态特征提取处理指对输入变量的历史数据序列按照设定计算方式进行处理;将特征数据输入至已训练的状态检测模型进行处理,得到驾驶员的状态;状态检测模型由预先构建的时间递归神经网络训练得到。与现有技术通过车载摄像头检测驾驶员面部特征以判断驾驶员的状态相比,本方法通过动态特征提取可以提取出更有意义、更具代表性的信息,不仅减少了数据的维度,还保留了数据中最重要的特征,从而提高了对驾驶员的状态的检测准确率和检测精度。
