Police capture crime scenes in 3D
Police forces are embracing the latest 3D-scanning technology to record crime scenes as virtual reality models. This helps them find clues, but also to immerse juries in the scene of the crime.
London's Metropolitan Police is one force which has used the technique, and it is being used nationwide to investigate traffic accidents.
The same technology was initially used for land surveying and other industrial applications.
David Southam of Faro, a US company that specialises in 3D measurement technologies and has manufactured equipment used by UK police forces, explained to BBC News how the kit works.
