Finally got some time to take a video.. The implementation is pretty embarrassing..
Small hal file that runs opencv - sets some parameters for the houghcircle finder, bluring and some tolerances.. Gcode program tells the hal component to find a circle Hal componant finds circle and sets hal pins of its location Gcode program continues and reads the position from the hal pins. Gcode program calculates how much to move to center the frame I am not too impressed with the houghcircle function. I think it should work better but might not understand it. The view is about .001"/pixel the circle is .25" diameter http://youtu.be/Pe2RACwiEbg I will post the hal file and gcode program when I get back to it. sam On 10/07/2014 01:06 PM, sam sokolik wrote: > in the future one of my projects is shape recognition.
