Camera-Projector System
Application
A software for an interactive camera-projector system was developed by Juan Roldan at the Microsystem & Machine Vision Laboratory (MMVL) at Sheffield Hallam University, UK. The software is still under development, but it is planned to be released as open-source software in Q3 2006.
The software makes use of a low cost off-the shelf webcam that is calibrated against a standard projector screen. The webcam is used to determine the position of physical pointer (e.g. a pen) which is then used to virtually move the X11 pointer. Point-and-click functionality has also been implemented.
The vision system uses the Mimas real-time computer vision toolkit developed by the MMVL.
How it works
Mouse clicks
The standard deviation of a few recent mouse-positions is used as a criterion, wether the mouse is stationary or moving. If the mouse is stationary, a mouse click is issued.
