"The Smart Bookshelf: A study of camera projector scene augmentation of an everyday environment

Recent research in projector-camera systems has overcome many of the obstacles to deploying and using intelligent displays for a wide range of applications. In parallel with these developments, projector costs continue to decline with corresponding increase in resolution, brightness and contrast ratio. In light of this trend, we are exploring the unique capabilities that camera-projector systems can offer to intelligent environments and ubiqutous computing. Our initial step towards environments that are intelligently augmented by projector-camera devices, is a smart bookshelf application. The system utilizes a camera pair and a projector to monitor the state of a real world library shelf. As books are added to the shelf a foreground detection algorithm which takes into account the projected information yields new pixels in each view that are then verfied using a planar parallax constraint across both cameras to yield the book spine. Using a simple calibration scheme, the ho...
