If you want to, you can download the manual from the website. It offers some insight into the basic algorithms involved (adaptive image segmentation is the main one). Another featue is that the system natively uses 320x240 images, and scales the centroids down by two for output purposes. I will probably put a little more detail on the main products page; thanks for the suggestion!

I did not make this open source as I have been working on the algorithms for the past 2 1/2 years, and would like to make a little bit of profit so that I can fund my other vision systems research. It is hard to continue researching with no funds available to test ideas with! Besides, it is written for an FPGA, an FPGA which is pretty much filled up by the code. (1 million logic cells, all in use! )

The OV7620 camera module itself is not a bad module for this kind of work. I have yet to see this distortion you speak of, and I have had the oppertunity to work with 6 different OV7620 modules. Out of curiosity, did you plug both of them (one at a time, of course ) into the same CMUCam board or different CMUCam boards when you noticed the distortion?

If it's falling apart it's a mechanical problem. If it's spewing smoke it's a electrical problem.
If it's rampaging around destroying things it's a programming problem.
