Coming Attractions
One of the newest trends in machine vision systems is the implementation of so-called "smart cameras." A smart camera combines the usual image sensor with a built-in processor, which allows inspections to be run directly on the camera, thereby eliminating a step in the process. Instead of simply capturing images, like a...
