London, Jan 12 : Forensics experts would no longer have to visit the site of a crime again and again for their probe, thanks to Kiwi researchers who have developed a
3D scanner that can create a `virtual' model of any given area.
The team led by Robert Valkenburg of Industrial Research in Auckland, New Zealand, has developed a computerised 3D model that can be navigated as if investigators were at the crime scene.
The hand held device consists of a laser scanner combined with a digital camera, which can record a scene with millimetre accuracy.
The scanner creates a 3D model of the scene, onto which images from the camera are superimposed.
