In our experiment, we used three black boxes placed
on the desk. See Fig. 10. We will use modeling system
to simulate these boxes in the 3D virtual world. And we
will compare the position with its real position.
After processing by the vision system, we finally got
the depth image shown in Fig. 11. From the depth image
we can acquire 3D coordinates of the points. Key points
are selected by the selecting system. (See Fig. 12.)
Then with the information we got from vision system,
we build 3D model of the boxes in the virtual world.
(See Fig. 13.)
