I recently started working with the camera-tracking estimator to produce short augmented reality videos. I'd like to learn more about the lens model and its parameters (K1, K2, etc...).
Can anyone tell me the specific name of this lens model, or the general theory it belongs to? Would this model/theory fall be covered by the general study of undergraduate-level Optics as taught by a Physics department, or in what book or article would I be able to learn more about it? (Assuming I meet any basic calculus and linear algebra prerequisites).
