Raccourcis clavier

Many tables, such as the reacTable are using wide-angle lenses to increase the area visible to the camera at a minimal distance. Since these lenses unfortunately distort the image, reacTIVision can correct this distortion as well as the alignment of the image.

For the calibration, print and place the provided calibration sheet on the table and adjust the grid points to the grid on the sheet. To calibrate reacTIVision switch to calibration mode hitting C.

Use the keys A,D,W,X to move within grid, moving with the cursor keys will adjust the position (center point) and size (lateral points) of the grid alignment. By pressing Q you can toggle into the precise calibration mode, which allows you to adjust each individual grid point.

J resets the whole calibration grid, U resets the selected point and L reverts to the saved grid.

To check if the distortion is working properly press R. This will show the fully distorted live video image in the target window. Of course the distortion algorithm only corrects the found fiducial positions instead of the full image.
