Re: cRIO, has it 'upped the game'?

If I understand the way the color thresholding works, a smaller band of threshold values should process faster. An illuminated target throws more consistent light, allowing you to tighten your calibration. The main issue with tracking now is the latency between the real world and output of tracking software. We are getting relevant data at 15Hz, which is plenty fast for "sit and pick". Unfortunately the name of the game is "pin and puke", at least up to this point.
