POSTURE ESTIMATION SYSTEM, BEHAVIOR ESTIMATION SYSTEM, AND POSTURE ESTIMATION PROGRAM

摘要

To provide a posture estimation system capable of accurately estimating a posture of a person in a photographed image while suppressing learning data used for machine learning, regardless of the posture of the person.SOLUTION: A posture estimation system, which estimates the posture of an object person based on a photographed image, includes: a human region detection unit that detects a region including an image of the object person in the photographed image as a human region; a head region detection unit that detects a region including a head image of the object person in the photographed image as a head region; an image rotation unit that unifies a direction of the head region with respect to a predetermined point in the human region in the photographed image in which a plurality of postures of the object person are respectively photographed by rotating each of the photographed images in a predetermined direction; and a posture estimation unit that estimates a joint point of the an object person as a posture by machine learning based on the photographed image after rotation.SELECTED DRAWING: Figure 3
