Hello,

I have been working with Augmented Reality as part of my final year
project at my university and I have a simple question I hope you can
answer.

I use a simple webcam (Lenco) for AR. A calibration of the camera reveals
no detectable first order radial lens distortion k_1. Other webcams I have
tested from Lenco have not had any detectable k_1 either.
Is it a fact that most modern webcams have such high quality that they
have no radial lens distortion? I have tested older cams and they all had
distortion to some degree.
