Title:
JOINT OBJECT POSITION AND POSTURE ESTIMATING DEVICE, ITS METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2007/010893
Kind Code:
A1
Abstract:
A joint object position and posture estimating device enabling reduction of the
cost of model fitting computation for estimating the position and posture and
having an improved estimation speed. A posture model storage section (2) stores
information on a posture model having low-dimension parameters under the movement
restraint. The information is determined by analyzing the main components of
the time-series postures of the joint object frame model corresponding to a predetermined
limited movement of the joint object of a human body or the like. A human body position
and posture estimating device (101) has a human model image creating section
(4) which creates images of the postures of the joint object frame model within
the range of the postures which the posture model takes on and a position and posture
estimating section (10) which estimates a posture by matching with the joint
object image to be estimated.
