Abstract

According to the present invention, a posture estimation system for estimating a posture using key points more appropriately acquires information indicating a portion constituting an object and hidden by a hand (S204, S402), determines three-dimensional positions of a plurality of key points for estimating the posture of the object on the basis of the information (S208, S405), trains a machine learning model for estimating the positions of a plurality of key points determined in an input image (S203, S407), acquires the estimated positions of key points in an image capturing the object and the hand on the basis of an output produced by the trained machine learning model in response to receiving the image, and determines the estimated posture of the object in a three-dimensional space on the basis of the estimated positions of the key points.
