Pros. This straight-forward 3D reconstruction task can be used to test the applicability of a 3D calibration/reconstruction system. The projector produce light beam for establishing the coresspondence as what a laser-scanner do. The result is accurate and reliable.
Cons. Lots of frames needed.
In this experiment, the 5Hz camera-pair make the system took about 50 seconds with more than 300 frames for scanning the whole puda. Thus, static object only.
