Title:
DRIVING STATE DETERMINATION DEVICE, METHOD, AND COMPUTER-READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/064592
Kind Code:
A1
Abstract:
The present invention makes it possible to accurately determine the driving state of a driver even when the size of the driver in driver images is not constant. A position detection means (11) detects the positions of the right and left shoulders and the positions of two or more body parts of a driver from a driver image captured of the driver. A shoulder width calculation means (12) calculates the shoulder width of the driver on the basis of the detected positions of the right and left shoulders. A threshold value determination means (13) determines one or more determination threshold values on the basis of the calculated shoulder width. A determination means (14) determines the driving state of the driver using the positions of the two or more parts detected by the position detection means (11) and the one or more determination threshold values determined by the threshold value determination means (13).
