Finding the dimensions of a object.

[Himanshu]

Hello friends,
I am acquiring images using a webcam. The image acquisition part is complete. Now I would like to find the dimensions of a object in front of the webcam. The object are geometrical in shape and are colored having a black background. I would like to know the way in which I can find out the dimensions of the object.

Are you using our IMAQ Vision toolkit for image processing? If so, please look at the VIs for particle analysis, complex measurements, and so. They will provide tools for finding the Perimeter, Area, etc.

If you are not using any processing toolkit and if you want to program an algorithm yourself please look at the following references that are good resources of digital image processing algorithms:

Good luck!
