Detecting the edges of the whiteboard and compensating for the projection plane are actually not that easy, but you're right that it's a solvable problem, at least under favorable conditions.
But I'm not sure exactly what conditions we imagine using the software for backgammon board recognition. Does the software already know which board is being used (e.g., the color scheme)? Is it supposed to notice that ten checkers are stacked in two layers of five checkers? Does it have to deal with blurring caused by taking the photo with shaky hands? Is it supposed to capture the dice and the cube? Depending on how robust the software needs to be to adverse conditions, the problem could range from relatively easy to very difficult.
You're right, though, that it's nowhere near as difficult as the problem Chase described. My first reaction is that the city must have been grossly ill-informed to think that such a project was even remotely feasible. If the software is supposed to figure out that the person getting off now is the same as the person who got on five stops ago, then I doubt that this is possible even today. They'd be better off installing card readers that you have to swipe both when you board and when you leave.
