Mobile phones to offer X-ray vision

Researchers at the University of South Australia with the collaboration of Nokia have come up with software, which will offer X-ray vision to see what's on the other side of the building, reports ANI.

The application works by using the phone's camera. Users can point the camera at a building and an image of it would appear on the screen. Then, the image would change to show what was behind the building, as if it was no longer there.

The application is likely to be introduced in the market in the next two years. The technology, known as augmented reality, appears to be X-ray vision, but in reality it uses pictures and images that already exist in databases such as Google Earth and Google Streetview.
The application needs two pieces of information: 3D model of the area or city the phone user is in and the user's exact position. A 3D model of a city could be built using information collected from aerial surveys. The technology could not be used to see into people's houses because only the exterior views of buildings and streets were held in the databases.

GPS is used to work out the user''s exact position. Once the software knows this information, it uses information and images from the 3D model to display a picture of what is behind the building.
