We present a posture measurement method that uses foot pressure distribution and video camera images. The method first estimates the position, posture and size of subject n the real world from his or her foot pressure distribution. A stick model represents these estimates. The position of the skeleton in the camera image is then detected by using the estimated skeleton obtained by projecting the stick model onto the camera image as initial value. We tested this method on 80 walking patterns of eight women. The results show that the detected skeleton lies at the center of the leg.
