What is Street View & Why it is important for us ?

• Street View:

One type of digital mapping

Digital mapping is the process by which a collection of data is compiled and formatted into a virtual image.

The primary function of this technology is to produce maps that give accurate representations of a particular area, detailing major road arteries and other points of interest

Processing of Street View

• Image acquisition

• Geo-tagged photos

Geotagging is the process of adding

geographical identification data to

various media

Capture photos use

adapted vehicles with cameras

and laser scanners

Processing of Street View

• Reconstructed virtual image

Image stitch--Navigable images are obtained that there is dramatic overlap between the frames in both horizontal and vertical directions

--Then different image techniques have been used to stitch the panoramic scene together.

Street View’ s future

• An challenging thing ： linking 3D modeling to 3D Geo-reference

Google ： Google earth view in Google maps

• Precision of GPS

The integration of navigation systems (GPS/INS/GNSS)

• Privacy protection
