Automatic Projector Calibration with Embedded Light SensorsJohnny Chung Lee, a PhD graduate student at Carnegie Mellon University, uploaded a video to YouTube on Saturday that demonstrates his thesis project: a technique for automatically discovering the locations of surfaces in the projection area using embedded light sensors.
No matter how he angles the viewing screen, the picture projected onto it lines up perfectly and is not distorted in any way. The calibration takes about 1 second for a perfect match, as opposed to the 5-10 minutes I spend moving tables, adjusting the leveling wheels on my projector and still ending up with a warped picture.
His technique also helps in performing automatic touch calibration of interactive whiteboards or touch-tables.
End result? When you're doing a presentation, you'd no longer have to have the projector smack in the middle of your conference table . . .
