Tutorial on digitizing videos with DLTdv3

Here is a short tutorial on getting started with using DLTdv3 or DLTdv5 to digitize videos, with a particular emphasis on generating coordinate data for 2D kinematics. This document augments the video Tutorial 1 available at: http://www.unc.edu/~thedrick/software1.html.  The example video is on animal locomotion but the instructions apply to animal feeding, as well as other behaviors.
