Camera Calibration Toolbox and now?

Now that I successfully calibrated my camera, how can I transfer these parameters to some pictures I took with those settings? I have the calibrationSession.mat file but I kinda want a matrix that is can multiply with my images. Or how is this done?

Cheers, Jonas.

I'm assuming you have used the Camera Calibrator app to calibrate the camera. After the calibration is done and when you are satisfied with the results (look here for more information), you can export the camera parameters to an object (more info here).

This exported object has information about the camera parameters like the 'IntrinsicMatrix', 'RadialDistortion', etc. which can be accessed through the standard dot notation like so:

cameraParams.IntrinsicMatrix

More information about these parameters can be found here. Depending on the application, you can use these parameters to work on the images captured by this camera. As an example, if you want to remove the radial distortion from an image captured by this camera, you can use the

cameraParams.RadialDistortion

parameters as explained here in the MATLAB documentation .
