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
- KDE-miniprogram with configuration wizard
Gallery
Downloads
You first need to install the 4th unofficial release of Mimas-2.0 (28 MByte) of the Mimas Real-Time Computer Vision Library to be able to compile and run version 1.4 of the interactive software (229 kByte).
