The invention belongs to the technical field of automatic driving, discloses a driving workload calculation method based on eye movement data, and is applied to monitoring the working state of a driver in the field of auxiliary driving. Eye movement data are collected through the glasses type eye tracker, the workload of the driver is calculated, and therefore the working state and working coincidence of the driver are evaluated in an auxiliary mode. Therefore, a data set of eye movement of a driver in a real scene is established. Then, ten eye movement data indexes are selected for statistics, and weight values of the ten eye movement indexes are calculated; and finally, weighting and calculating the driving workload under different driving scenes or behavior events by using ten eye movement index weights and real eye movement data. The invention provides an effective method for an auxiliary driving system to monitor the workload of the driver, and provides another strategy for an intelligent driving or advanced auxiliary driving system.
本发明属于自动驾驶技术领域,公开了一种基于眼动数据的驾驶工作负载计算方法,应用于辅助驾驶领域监控驾驶员的工作状态。本发明使用眼镜式眼动仪采集眼动数据,计算驾驶员工作负载,从而辅助评估驾驶员的工作状态和工作符合。为此,本发明建立一个真实场景下驾驶员眼动的数据集。然后,选择了十项项眼动数据眼动数据指标进行统计,并计算了十项眼动指标的权重值。最后使用十项眼动指标权重和真实眼动数据加权计算不同驾驶场景或行为事件下驾驶工作负载。本发明为辅助驾驶系统监控驾驶员工作负荷提供了一中有效的方法,为智能驾驶或高级辅助驾驶系统提供了另一种策略。
