That looks like a very interesting project! The BeagleBone should be able to handle the 4-axis machine control, but I'm not sure about handling the vision pipeline. I know some people have been doing machine vision projects with the BeagleBone, but I have no personal experience in this area. I recommend asking about machine vision on the BeagleBoard Google Group:
https://groups.google.com/forum/#!forum/beagleboard A PC will give you *MUCH* better performance for the vision pipeline, but then you will need something to move the motors, which means more cost and electronics (Mesa hardware, Arduino, or even the BeagleBone). If you're not real worried about speed, the BeagleBone will probably be able to perform the vision tasks you need, just slowly.
