Real-world objects have depth, width and height, and automated systems such as robots need to “see” in these three dimensions if they are to operate successfully.
IN CONTRAST TO TRADITIONAL MACHINE VISION SYSTEMS THAT PROVIDE INFORMATION IN TWO DIMENSIONS, 3-D PROVIDES MORE INFORMATION ABOUT MANUFACTURING PROCESSES.
Manufacturing has made increasing use of traditional 2-D machine vision inspection, optical character recognition (OCR) and ID reading systems, which increase quality, improve throughput and reduce costs.
