3. Type of camera used for Street View

The Street View camera systems have 15 lenses and can produce photos at about 65 megapixel resolution. When Street View was still in the experimental stage, the team packed several computers in the back of an SUV and placed cameras, lasers and a GPS device on the roof.

2. Secret behind seamless panoramics

The 15 lenses in the Street View camera system take photos in various directions, and adjacent cameras on the car take overlapping pictures. The team then aligns the photos and stitches them together to create a continuous 360-degree panoramic image.

In addition to the fleet of Street View cars, Google has trikes, trolleys and snowmobiles. The Trike captures parks, trails, college campuses, stadiums and other areas that an SUV can't access. The Trolley is used for navigating a building's interior and doorways. The Snowmobile captures images across snowy terrains. The team came up with the idea when Vancouver held the 2010 Winter Olympics.
