If a GPS signal can’t get through, imaging data might be the
answer
Whether you’re walking, biking or driving, navigation
systems can help you get from A to B – as long as you have a GPS signal. This
positioning technology usually works fine in both urban and rural outdoor
areas, but it is of limited use indoors. To find our way around large and
complex buildings like hospitals or airports, we often need to rely on vague
signs. Researchers at Technische Universität München (TUM) have come up with a
new technology. The NAVVIS system uses visual information and realistic 3D
images to point users in the right direction.
