Title: Which CMUCam?
Post by: tuttut89 on December 30, 2006, 11:10:44 PM

I have looked on the official site and searched many forums so please don't burn me on this question :)
(and I did read the object detection question posted earlier)

I have a limited budget and would like to do some object recognition with a cmucam but I don't know which version I would need.  I would like to run through a basic algorithm to detect a certain shape and then look at the center of the object.  I read that the CMUCam2 accesses pixel data from the frame buffer, making it faster, but what does this mean? Will there be lower fps?  If I were to do all of this calculating from a microcontroller, how fast would that microcontroller need to be?  Last of all, would it be best to just save my money for a cmucam3?

I will appreciate any help, and I hope you have a Happy New Year! ;D

I would look at the AVRcam, which does more or less the same thing, but is open source, and costs somewhat less.

I have decided to purchase the CMUCam2, since it has faster frame dumps and I read somewhere that the CMUCam1 took forever to dump a frame.

As someone who has used the CMUcam1 on multiple robots, I would highly discourage anyone from using it.

It has serious firmware bugs, poor mounting holes, a misaligned camera lens from poor manufacture, and very little available source code.  :(

I havnt used CMUcam2, but curious if it has the same problems . . . let us know how it goes.

hi, do anyone have object recognition program code for CMUcam3? or the step?

It doesnt have object recognition built in. Do you mean uploading video data to a PC that then does object recognition?

this page has source code that you might want:
