Whiteboard Scanning: Get a High-res Scan With an Inexpensive Camera

A whiteboard provides a large shared space for collaboration. In order to capture the contents with readability, a high-res camera is required. If one only has an inexpensive camera such as a laptop/tablet built-in camera or a web cam, she can use the Whiteboard Scanning system described in this paper. It captures either a set of snapshots with overlap or a continuous video sequence, and then stitches them automatically into a single high-res image. The stitched image can finally be exported to our Whiteboard It! system for further enhancement.
