Machine vision processes have become standard practice in quality assurance. Inspecting reflective surfaces, however, presents a challenge. A technology known as deflectometry can be used to reliably detect all types of defect even in these circumstances.
Machine vision is used today in many quality assurance applications. The technology can reliably identify products with manufacturing defects using optical methods. Cameras record the objects to be inspected from different perspectives and generate large amounts of digital image data. This data is then processed by integrated machine vision software and used to detect faults, making it possible to automatically remove rejects before they enter the downstream logistics process chain. This method is used in all manufacturing industries, including mechanical engineering, food and beverage, pharmaceuticals, and electronics.
