Title:
POSITION DETECTION DEVICE, PHYSIQUE DETECTION SYSTEM, AND POSITION DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/239048
Kind Code:
A1
Abstract:
This present invention comprises: a feature point detection unit (11) that detects, on the basis of a captured image captured by a camera (2), a target feature point in the captured image corresponding to a part of the human body; an angle calculation unit (12) that calculates, on the basis of a position of the target feature point on the captured image detected by the feature point detection unit (11), a feature point position angle representing the angle of a straight line connecting the camera (2) to the target feature point with respect to the imaging axis of the camera (2); a distance detection unit (13) that detects a first distance from a distance measurement sensor (3) to the target feature point on the basis of sensor information acquired by the distance measurement sensor (3); and a position identification unit (14, 14a, 14b) that identifies the three-dimensional position of the target feature point on the basis of the feature point position angle calculated by the angle calculation unit (12) and the first distance detected by the distance detection unit (13).
