Qi Pan, a 3rd Year PHD student at Cambridge University has developed 3D scanning software that uses a standard web camera.
The software can reproduce a 3D textured model from a real object, this is done by holding the object in front of a standard webcam and then rotating it, the computer then calculates the information needed to re-produce the model in 3D.
The generation of 3D models is very useful for many computer vision applications. This paper introduces ProFORMA, a system designed to enable on-line reconstruction of textured 3D objects rotated by a user’s hand. Partial models are created very rapidly and displayed to the user to aid view planning, as well as used by the system to robustly track the object pose. The system works by calculating the Delaunay tetrahedralisation of a point cloud obtained from on-line structure from motion estimation which is then carved using a recursive and probabilistic algorithm to rapidly obtain the surface mesh.
