本发明提供一种驾驶压力实时监测系统及方法,包括:构建驾驶场景及事件;设定事件发生地点与客户端在驾驶场景中位置之间的第一距离和第二距离,使得事件成为有压力事件和无压力事件,结合驾驶场景生成有压力驾驶任务和无压力驾驶任务,采集客户端在有压力驾驶任务和无压力驾驶任务中的驾驶行为数据和面部表情数据;构建机器学习模型;将有压力驾驶任务的驾驶行为数据超过设定阈值的驾驶行为数据对应的面部表情数据构成有压力数据集,将对应的无压力驾驶任务中面部表情数据作为无压力数据集,对机器学习模型进行训练;采用训练后机器学习模型对客户端驾驶行为进行实时监测。上述系统及方法对驾驶过程中压力水平实时监测。

    The invention provides a driving pressure real-time monitoring system and method. The method comprises the steps that a driving scene and events are constructed; a first distance and a second distancebetween the event occurrence place and the position of a client in the driving scene are set so that the events are enabled to be pressure events and pressure-free events, pressure driving tasks andpressure-free driving tasks are generated through combination of the driving scene, and the driving behavior data and the facial expression data of the client in the pressure driving tasks and the pressure-free driving tasks are acquired; a machine learning model is constructed; a pressure data set is formed by the facial expression data corresponding to the driving behavior data of the pressure driving tasks exceeding the set threshold, and the facial expression data in the corresponding pressure-free driving tasks act as a pressure-free data set to train the machine learning model; and the driving behavior of the client is monitored in real time by using the trained machine learning model. According to the system and the method, the pressure level in the driving process can be monitoredin real time.
