摘要： A method and system for monitoring eye fatigue is provided, which is based on the alteration of water concentration in periorbital skin during an eye fatigue process. The method comprises: illuminating periorbital skin with Infrared light having a first intensity; measuring a second intensity of Infrared light reflected from the periorbital skin; and determining a level of eye fatigue based on at least the second intensity of Infrared light. The measuring may be implemented by an active IR imaging system or a non-contact fiber-optic spectroscopic system. The system may comprise an Infrared light source unit, an Infrared optical sensor unit, and a processor. An eye fatigue index (EFI) reference model is also provided for eye fatigue level evaluation.

摘要： A light monitoring system, a glare prevention system, a method of monitoring glare and a vehicle 102 are provided. The light monitoring system comprises a camera system 114, a user's eye tracker 110 and an incident light calculator 124. The camera system 114 records at a camera location incident light from a light source. The user's eye tracker 110 determines a position of the user's eyes104. The incident light calculator 124 calculates perceived incident light by the user's eyes 104 and transforms the recorded incident light at the camera location into the perceived incident light at the position of the user's eyes. The perceived incident light may be used to estimate whether the user 106 perceives glare and this information may be used to control a dynamic light intensity filter such that the light originating from a too bright light source is dimmed.
