Title:
VEHICULAR MONITORING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/059835
Kind Code:
A1
Abstract:
In this vehicular monitoring device, an imaging unit 2 captures an image of the driver of a vehicle. A driving state measurement unit 70 analyzes the image captured by the imaging unit 2 and measures a plurality of driving states including the eye opening degree of the driver. A travel state determination unit 71 determines the travel state of the vehicle. An alarm determination unit 72 uses the driving states and the travel state as a basis to determine whether to activate an alarm device 5. When a statistical amount calculated from time series data for the eye opening degree acquired from the driving state measurement unit 70 is outside of a predetermined normal determination reference range, the driving states other than the eye opening degree are normal, and the travel state is determined to be normal, the alarm determination unit 72 causes the driving state measurement unit 70 to perform eye opening degree detection processing again.
