--Apple-Mail-9--269817546 Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowed I was doing ARToolKit's two step method Camera-Calibration. What can it cause, that the "artoolkitplus" application is unable to load the resulting "dfk21af04.dat" file? there is not really an interpretable error message. getting a false back of the following method: FTracker->init(&FCameraFile[0], 1.0f, 1000.0f) perhaps somebody can take a look at the file. kind regards Norbert --Apple-Mail-9--269817546 Content-Transfer-Encoding: base64 Content-Type: application/octet-stream; x-unix-mode=0755; name=dfk21af04.dat Content-Disposition: attachment; filename=dfk21af04.dat AAACgAAAAeBAhu3ERw56gL/Y5Mh/NRacQHQM42NYXmEAAAAAAAAAAAAAAAAAAAAAQIbC0R5liiFA Y8Vy6bQn7wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAD/wAAAAAAAAAAAAAAAAAABAd3AAAAAAAEBs IAAAAAAAQD2zMzMzMzM/8ECLdepn6A== --Apple-Mail-9--269817546-- |

hi Norbert, we generally advice using the Matlab camera calibration toolbox to calibrate cameras for ARToolKitPlus. It gives more precise results with a lot less work... Daniel |

Hi Norbert, I ran into a problem of not being able to load my generated calibration = file also. When I tried to debug things, I discovered that the calibration = matrix being loaded had a negative matrix entry where a positive one was = expected, and so the init returned false. I don't know why it did this. Using the matlab generated calibration file worked for me. Regards, Victor -----Original Message----- From: owner-artoolkit@h ..................
