Bundle-Block and AT. What is the difference?

We were introduced to bundle-block adjustments in the last lecture. What difference, if any is there between aero-triangulation (AT) and and bundle-block?

My impression is that AT is a specific application of the bundle block adjustment, focusing on the intersection solution.

AT is suggested in research as the method to generate point clouds using computer vision from highly overlapped images from systems such as ultracam.

Am I on the right track?
