Without giving away too much of it...I've got something in mind at work that would use a stereoscopic vision system to detect some specific objects. It needs to differentiate them from people walking by, but also determine their direction of travel, and then report some simple information to an external system via RS-485. I'll also guess that the finished sensor will likely need to cost less than $600. My starting point: I know squat about vision systems. I've seen that OpenCV is something that exists. I don't really know where exactly to even start looking, or what I'm looking for. Is this something where we'll need to bring in a computer science person to do this kind of thing? Or a team of Ph.Ds? Or could a properly-trained monkey handle it? Is there a good starter kit of some sort? Fisher Price's My First Vision Sensor?
