is there a name for what I want to do?
You should maybe have a look on ImageJ (http://rsbweb.nih.gov/ij/). ImageJ associated to hundred of scripts and plugins will allow you to handle nearly any project in the frame of image analysis/Still and video images processing.
Among my favorits are:MosaicJ (http://bigwww.epfl.ch/thevenaz/mosaicj/) stich together multiple fields in near any shape and picture number with a precision which is difficult to reach by hand
