Automatic Generation of Walkable Paths in Buildings to Support Indoor Wayfinding (PDF)

Automatic Generation of Walkable Paths in Buildings to Support Indoor Wayfinding
“Abstract -We have created a prototype system that generates walkable paths in a building using AutoCAD floor plans. Our system is designed to work with the CampusGuide, a commercial indoor navigation system. Path-generation is done once for each floor plan, creating a network of walkable paths between all points of interest. The A*algorithm we have implemented takes roughly fifteen seconds to build paths for a

building floor, which is much quicker than what a human can do manually. The error
rate is fairly low, but still an issue for commercial use”
