After Camera calibration, how do I upload the distortion values?

edit

what I got after calibrating my camera were two files, one with the intrinsic matrix, and the other one with the distortion coefficients. So, is the intrinsic matrix the same as the camera matrix?

yes it is .

if you're looking for a way to read it back in:

<code>

Mat cm;

FileStorage fs("cam.yml", FileStorage::READ);

fs["M"] >> cm; // no idea about the key, take, what's in your file there!

</code>

yes I read the reference manual. but I think it would be faster to set those values as constants at the very biginning of the program instead of reading them from the field. I was trying to set them like this, but it didn't work

Mat* cameraMatrix= {8.19086426e+002, 0, 2.62020386e+002,0, 8.19086426e+002, 2.61436218e+002, 0, 0, 1,}

then I tried the following but didn't work either.

Mat* cameraMatrix[9]

cameraMatrix[0]= 8.19086426e+002;
cameraMatrix[1]=0;
cameraMatrix[2]=2.62020386e+002;
cameraMatrix[3]=0;
cameraMatrix[4]=8.19086426e+002;
cameraMatrix[5]=2.61436218e+002;
cameraMatrix[6]=0;
cameraMatrix[7]=0;
cameraMatrix[8]=1;

:/ do you know how to initialize them?

`double arr[] = {0.0819, 0, 0.0262, 0, 0.0819, 0.0262, 0, 0, 1};

Mat cm(3,3,CV_64F, arr);`
