Hello everybody,

I'm have to do a project at university. It's about object tracking with 4 DMK 21 F04 cameras. The problem is, that cannot calibrate the cameras with this code:
http://docs.opencv.org/_downloads/camera_calibration.cpp
We tried the code on internal webcams an usb cams, everything works fine. But with the imaging source cams, the calibration crashes after 1-2s. But it is possible to capture the video and work with that, so we have the input.
We thought, that we have 3 possible problems:
1) DMK 21 F04 is a monochrome camera
2) FireWire could be the problem
3) Maybe the fps are to high?

We would really like to get some support, we are using OpenCV 2.4.8 on Xubuntu with eclipse.

Regards
Nils

Do you receive an error message?
I am not an OpenCV professional, therefore, I do not know, how the calibration works.

BTW: I am located in Bremen, near B├╝rgerweide / Schlachthof.

Did you try to decrease cams resolution?
