Camera Input

[Massey101]

Hey, I’m looking at a project at the moment that has to do with navigating water with bricks in it and apparently we have to use the arduino UNO board. One thing I was looking at was using the video shielder and a very very low resolution camera to get an idea of which direction to head in. (e.g. if there is a majority of orange on the left turn left, if the orange is centred, go straight ect…)

The problem is I was hoping to get say a 50 x 10 pixel camera that uses 8 bit colour (doesn’t have to be exactly this but that’s the general idea). It has now become apparent that getting resolutions that low is almost impossible. So now I’m looking at having a higher quality camera and preforming the processing on the video experimenter. The idea is it will process the video and identify colour groups (orange for ping pong balls and brown for bricks) and then set these positions to the ardiuno which will make the decision on what to do.

I was thinking of using something like this camera in terms of price and resolution. http://www.gottabemobile.com/2008/11/07/cheap-webcam/
I only need a frame rate of say 1 frame a second? Would this even be possible?
Suggestions of other cameras would be good but price is a very big issue here as we are being assessed on it.

You can’t distinguish colors with the Arduino and Video Experimenter shield. You can only determine a brightness threshold for monochrome. Please understand that the Arduino and a sync separator chip are very primitive, but you still can do some neat things. Image processing with color is not possible though….
