TechCrunch recently showed off one of Google’s latest developments, the Cartographer, a backpack designed for mapping indoor spaces. Google Maps uses a backpack called Trekker, which includes a complete Street View camera setup, for mapping anything in outdoor environments. For indoor mapping, the Cartographer uses a process called “simultaneous localization and mapping” (SLAM), a technique that’s typically used for mapping new locations. Google is using the Cartographer to map buildings such as hotels and museums. As the backpacker walks through a building, the floor plan is automatically generated in real time, Google says. The wearer also uses a tablet to add points of interest while walking around the building such as room numbers in a hotel or the particular exhibits in a museum.
