I will be presenting a method for fully automated calibration of lens distortion and camera intrinsics. We use structured-light patterns using a LCD to generate a dense map between the display and the image coordinate systems. This approach allows us to easily correct the distortion even around the edge of a camera image in sub-pixel accuracy, without assuming any model of lens distortion.
I haven’t published this work to any conference or journal, and still wondering if I can claim the novelty of this work. Recently I found several work which is closely related (or fundamentally equivalent) to our work. One of them is here.
