I came up with a project for which I'll need a couple of cameras and process their output ideally realtime or with slight delay (feature detection and tracking). Initially I thought about buying couple of cheap web cams, then I realized their framerate and resolution isn't good enough and drivers aren't generally good either. So I went online to look for some sensors and found this website digikey.com with a list of hundreds of sensors. But that only found a few items and from only 3 different manufacturers. Also the pricing seems a bit weird. Well ~$10 for 400x400px unit seems like OK, if I didn't have to buy 2500 units in total. On the other hand there are 640x480 sensors for $110. So while I understand buying thousands of units will be always cheaper then buying a single one, I'm a bit confused from this disproportion of prices. I also found different website, but that doesn't list prices and manufacturers says, on their websites, to contact their sales dept.
So the actual question is:
- Do you know a sensor that is around 800*600px and 120FPS or faster + it's price?
I'd expect maybe around $50/unit, but I don't really know how much these things cost.
