Well, I was thinking about that, and in theory, yes, but if someone decides to walk in front of my little robot while it's making its way from point A to point B, it might not 'see' the person with the vision system until it's too late. So I wanted to add a little bit of redundancy for those sorts of instances.

Also, with regard to the use of autofocus lenses, I would think that just like in regular photography, you would want to just focus the lens at the hyperfocal distance. that way, everything from half of that (hopefully relatively small) distance to infinity would be in focus.

I subscribed to the OpenCV mailing list a while back when I saw that thread, and proceded to get my inbox flooded , and I was planning on maybe using some of their algorithms where possible. I was just planning to use the OV cameras just because they're what I have access to. Kevin, can you think of different cameras that are low cost and may be better suited to my application?
