Recovering shape using shadow images

This project is focussed on the recovery of environmental shape or layout using shadow information from a moving light source. The approach allows a mobile robot holding a camera to remain at a fixed location in the environment while a second robot carries a light source. The shadows allow for the recovery of the shape of both directly visible parts of the scene as well as portions that are hidden from the direct view of the camera. This approach has pragmatic advantages in terms of robust and efficient scene recovery.
