Agenda

Industrial applications Quality control Inspection of presence/absence Metrology/Gauging Classification Process control OCR/Barcode/QR code lecture

Some examples… Guiding robots for assembly, pick and

place, and palletizing operations.

Real case:A series of packages have to be located

over a moving conveyor belt in order to automatically place them inside a box.

More examples… Real cases:

Piston assembly inspection

PCB inspection
