Hello,

I am doing camera calibration for external logitech camera using this file.

link text

I am changing cameraId in source code to 1,

int mode = DETECTION;
int cameraId = 1;
vector<vector<Point2f> > imagePoints;

But after compiling, when I run calibration.exe in command line, it is not opening external camera but again opening PC camera.

am I missing something here to add in source code?

thanks.

how exactly do you call the program ? (it probably got overwritten by sme param / config item)

did you make an independant check, if VideoCapture(1) does the expected ?

It is not working.

But instead of that I have used this tutorial, link text by setting parameters in in_VID5.xml file and I got calibration data.
