Programmers Den / Mathmatic Concept Behind Whiteboard Calibration
« on: April 13, 2010, 07:51:04 PM »
I know this question has been answered multiple times before, but I was hoping I could get a more math based explanation of how calibration works. I need to understand it so I can modify your code to fit my needs and I always enjoy learning something new, but no one I've found explains the meaning behind the code. Could one of you explain the process you use to find the whiteboard plane using three or more input points (be it with matrices, geometry, etc.)? A simple algorithm would be useful too, though not the Warper class please because I can't make heads or tails of it.  :)
