... last year I've times the SRTM data von Trier and three-dimensional environment with processing output. Meanwhile, I've a bit busy with the ARToolKit , I made a few markers and my webcam calibrated so that the markers are detected very well. The ARToolKit is doing that is just that: identify the position and direction of previously eintrainierten markers in the camera image. There are now also under the name of the library NyAR4psg for processing and accordingly you can do with the position and direction information, then so too beautiful things. I have been excavated so even my old 3D height profile and on the camera image (via GSVideo ), which shows my desk down. Now the location of the profile is not determined by mouse movements, but the markers identified in the image dictates the situation. The screenshot section shows the virtually lying on my desk, profile (ok, granted, looks at other the course more spectacular ), below you can see the marker with the coordinate axes, Trier is about where I've won it. One recognizes the Avelertal (Above the T of Trier), the Olewiger Valley (above the last row of Trier), the Communion Linger round the mountain and the corresponding valley (Konz valley) below the cup. Rear left (on the tape, under the table edge) is the Ruwer, the broad valley below is of course the present river valley.
If the position of the camera fixed and known, it would take this course, absolutely no marker detection, so you can rotate with the marker, the profile, however, still on the desk and move. With other markers could then still areas such as highlight or set the zoom factor - the possibilities are there no limits.
The information from the marker position can be of course also use any different: as the virtual control and display of audio signals , to issue Midi signals , a large playground of possibilities.
