lookup table Assuming this is a table of values and not a physical object with 4 legs(!), it is possible that it has been generated from some complicated mathematical model which has mapped the target points onto the distorted image cast by the fisheye lens. Intermediate points in a lookup table of finite size can be found by interpolation, so in principle any image can be recreated. By the same token, an ordinary image can be deliberately distorted topologically to look like a fisheye image. On the other hand, I could be barking up completely the wrong tree.

I suspect this is something like a "table of settings."
