ABNORMAL POSTURE DETECTION DEVICE, ABNORMAL POSTURE DETECTION METHOD, AND VEHICLE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/100814
Kind Code:
A1
Abstract:
The present invention comprises: an image acquisition unit (11) that acquires a photographic image capturing a range in which the face of a vehicle passenger should exist; a feature amount extraction unit (12) that extracts a feature amount on the basis of the photographic image; a change amount calculation unit (14) that calculates a change amount of the feature amount from a feature amount of a reference posture of the passenger; a first determination unit (15) that determines whether the posture of the passenger is a normal posture, by comparing the feature amount and the change amount to a normal posture determination condition, comparing the feature amount to a normal posture determination condition, or comparing the change amount to a normal posture determination condition; a second determination unit (16) that, on the basis of the change amount and a machine learning model for which the change amount is an input and information indicating the presence/absence of a collapse of the posture of the passenger is an output, determines whether the posture of the passenger has collapsed, when the first determination unit (15) has determined that the posture of the passenger is not a normal posture; and a detection unit (17) that detects abnormal posture of a passenger when a state in which the second determination unit (16) has determined that the posture of the passenger has collapsed has continued for a period of time used for abnormality detection.
