Arm Circumference RRS feed

  • Question

  • Has anybody successfully managed to measure the circumference of a persons arm using the Kinect, even if it has been done using 2 sensors?

  • I haven't done it, but you could try to use a hybrid approach of Skeleton and Depth tracking:

    Take the arms 'bone' (a line between the points) and select one or more depth pixels that are in the same direction. Then take the difference between the bone and the pixel (in 3D...) -> this would be the radius^

  • Hi,

    Thanks for the reply. Doesn't the bone derived by the kinect (as in the line) not actually sit where your real bone is though, but in fact in front of the body closest to the kinect? So the only way I could see to do this would be to find the depth map point exactly perpendicular to the lines midpoint. However, I've attempted this and the perpendicular line is moving around quite a lot due to the innacuracy of the Kinect. Any more ideas on this?
