Gesture detection device, occupant monitoring system, and gesture detection method

Abstract

A gesture detection device includes: a hand candidate detection unit to detect a hand candidate that is a candidate of a hand of a person on the basis of a captured image obtained by capturing the person; a gesture detection unit to detect a gesture of the person on the basis of the detected hand candidate; a mask determination unit to determine whether or not the person is wearing a mask on the basis of the captured image; a cover detection unit to determine whether or not a mouth of the person is covered on the basis of face information of the person obtained on the basis of the captured image when the mask determination unit has determined that the person is not wearing a mask; and a determination unit to reject the detected gesture when the cover detection unit has determined that the mouth of the person is covered.
