What is Machine Vision

Machine vision provides manufacturing equipment the gift of sight. In a typical machine vision application, a video camera is positioned on a production line. It captures an image of the part to be inspected and sends it to the machine vision computer. The computer then uses sophisticated image analysis software to extract information from images and generate decisions about those images. Once the vision system has processed and analyzed the image, the inspection result is then communicated to other equipment on the factory floor, such as an industrial controller, a robotic arm, or a deflector, which removes the part from the line. This process is repeated for each part on the line, or continuously for process material, as it moves into position in front of the camera. Vision systems can perform inspections quickly enough to keep pace with machines that process thousands of items or material feet per minute, thus increasing both quality and productivity.
