This is my problem:
on my PC (XP SP3), the executable works fine (the marker and the object are in line), the same executable on a different PC ( same XP SP3) with the same camera has the problem as the topic
http://www.scolring.org/forum/viewtopic.php?id=321

I calibrated the computer that has the problem as described:

1 - 2.2 download opencv calibration: http://www.arkeon.dyndns.org/scol/openc ration.rar ...
2 - unzip to C: \ opencv_calibration
3 - print the C: \ opencv_calibration \ pattern.pdf without the setting fit to page
4 - measure a black square
5 - Open a Windows Console (command cmd)
6 - Type "C: \ opencv_calibration \ calibration.exe w-6-8-h-s 0025 or camera.yml-op" without the quotes
7 - is the 0,025-s size in square meter of a black
8 - Follow the instruction (move around the room like Showed the pattern here: http://www.uco.es/investiga/grupos/ava/node/26
9 - Copy the files in your yml disconnected partition (my documents \ Scola Voyager \ Partition_LocalUsr \ ..)
10 - yeah you can try it in the capture plugIT!

the file camera.yml , I have put into the folder of the executable but it not works well.
I have the wrong somewhere step ?

really strange.

try updating the webcam driver, and look at the webcam parameters

As Arkeon ...
and see if a windows service is not missing (PC 2) (start >> admin tools >> services)
close all others programs on both pc
you might look in the windows logs if a message is written (start >> admin tools)

The two computers are Windows XP with S3, the only problem that I observe it in the shell:
RMS error reported by calibrateCamera: 5.45909
Calibration succeeded. reprojection error avg = 5.46

What does this mean?

@gius

Look at this : http://www.scolring.org/forum/viewtopic … 1355#p1355 and below

Ok, XP SP3.
The same windows services are started on both pc ?
The same driver (version, ...) on both pc ?
