'Head Posture Estimation Device And Head Posture Estimation Method' in Patent Application Approval Process (USPTO 20230091546)

摘要

The following quote was obtained by the news editors from the background information supplied by theinventors: “Conventionally, a technique of estimating the position and posture in the three-dimensionalspace of the head of a person who is captured in an image (referred to as an “estimation target” hereinafter) by using a prepared three-dimensional model showing a person’s face (referred to as a “three-dimensionalmodel” hereinafter) is known. When the position and posture in the three-dimensional space of the headof an estimation target are estimated, there is a problem that the difference between the three-dimensionalmodel and the estimation target, causes an error to occur between the actual position and posture of thehead and the estimated position and posture of the head. A technique of correcting the estimated positionand posture of the head in order to solve the problem is known.
