Modify an OpenCV camera calibration model using known azimuth and elevation

Suppose I have a camera mounted on a pan-tilt unit. I calibrate the camera at zero azimuth/elevation, obtaining an OpenCV photogrammetric camera model. I then rotate the camera to a known azimuth and elevation and take an image. How can I modify the model using the azimuth and elevation to obtain a new model specific to that image?
Based on my understanding of the photogrammetric model, it seems that I should multiply the extrinsic matrix by a rotation matrix computed from the azimuth and elevation, and leave the intrinsic matrix unmodified. Is that correct?
