Camera-Projector System
Application
A software for camera-projector interaction was developed by Juan Roldan and Ushakiran Soutapalli at the Microsystem & Machine Vision Laboratory (MMVL) at Sheffield Hallam University, UK.
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.
Future Work
- More different mouseevents

Downloads
Download mando-0.1.tar.bz2 (339 kByte). For your convenience the required parts of Mimas are included in the package. To build and run the package do
tar xjf mando-0.1.tar.bz2 cd mando-0.1 ./configure make ./mando
Sorry, but make install is not fully implemented at the moment (the software would need to load the calibration-patterns from the data-directory). At the moment the images for calibration are loaded from the current working directory.
