Google confirmed today it's gathering 3D data along with the photographs it takes for its online Street View service, but says data currently remains "experimental".
"The imaging technology includes lasers that collect 3D geometry data," the company said Thursday in a statement. However, for now at least, the 3D information is just experimental, Google said.
Savvy observers, looking at Flickr pictures of Google Street View cars gathering images in Milan, had identified the 3D laser scanners in April. At the time, Google didn't comment at the time, but now has confirmed the scanners as well as the expansion of Google Street View to Europe.
Laser scanners can be used to produce detailed 3D models of buildings or other features, and overlaying photographic imagery can give those models a more lifelike appearance.
Microsoft has been working to add more sophisticated 3D models to its Virtual Earth site, also using automated technology. Microsoft's software lets people cruise above Las Vegas and a few other cities with detailed 3D maps.
