Tracking Multiple Objects

How could I track multiple circles that are the same color? Also.. Can I use vectors in roborealm, example: to measure the distance a object has traveled across the screen in a given time.

P.S. I'm working on a Multi touch table and need to track the light given off by the FTIR effect.

Yes, have a look at the Blob_Tracking module at


which tracks multiple blobs in an image and joins them with a previous image's blobs based on certain criteria. That should work nicely for your application.

If you have any issue post a video that shows what your camera sees and we can help with the appropriate modules/configuration.
