Human body posture measurement by matching foot pressure distribution to video images

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 in the real world from his or her foot pressure distribution. These estimates are represented by a stick model. 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
