In this demonstration, I place a small tripod into the scanner. It is
rotated ona turntable, and each of three webcams takes images from eight
sides. Then the images are thresholded, and the volumes that the silhouettes
imply are intersected to recover the volume of the object.
In a later
scene, we see the calibration cube I used to calibrate each of the cameras
and the software I wrote to do it.
