Want to take 3D picture and print it out using your 3D printer? This home-build kinect-like 3D camera is a simple solution. Hackengineer has presented a portable 3D camera that only uses an HVGA projector with an ordinary CMOS camera.
The projector is used to display structured lighting based on a set of images, while the camera captures snapshots of the scene. The data is fed into a Beagleboard where OpenCV, a computer vision library is used to rectify the images of the objects and then generate point clouds of the objects. Hackengineer uses free Meshlab to open the point clouds file, where the extra points can be deleted, the point cloud can be oriented and color can be added to the depth to make it stand out.
Hackengineer displayed the final 3D images which is "pretty good for a completely portable setup and HVGA projector", said they.
On Hackengineer website they have showed you how to build this project step by step. The source code is posted on Google Code and you can download it straight from the interwebs with beagleboard.
