Tracking Rectangles

[Greg McKaskle]

I can't find the white paper on the NI site yet, but one should be posted soon that covers several approaches. One approach uses simple particle analysis to identify the ones most like hollow rectangles. Another approach is to use the line or rectangle geometric fit routines -- which are Hough implementations under the hood.

The paper actually uses NI Vision Assistant for most of the exploration, but does refer to the LV example when it comes to scoring and position/distance calculation. The LV example will also run directly on your computer, so your cRIO can run whatever, and the laptop can pull images directly from the camera that is on the switch.
