Homemade SMD Pick and Place Machine - Fiducial Alignment Test

Testing fiducial alignment on my homemade pick and place machine and paste dispenser named 'PP4'.
More details on my website: www.vbesmens.de
The vision system uses OpenCV:
It uses the Hough circle algorithm to detect the 1.5mm diameter fiducials within an area of interest. The fiducials are located on two opposite sides of the PCB. After detecting them, it checks if their distance is as expected. It then calculates the angle of the PCB on the machine using trigonometric functions.
The resolution of the camera is 67µm per pixel.

I love that it's fast. Too many pokey DIY pick and place machines.

Positioniergenaugkeit mit Marker und Laser im zehntelbereich, klasse. Geht aber nur relativ, nicht absolut, da Riemen sich dehnt durch temperatur etc!!

Your machine is shaking too much
