What is a vision sensor?

Vision sensors are automated solutions designed to handle straightforward error-proofing tasks. Typically, they execute a single function at a time, such as binary classification, defect detection, optical character recognition (OCR), object counting, and assembly verification.

Surpassing other types of sensors like photoelectric, laser, and proximity sensors, vision sensors merge the image-capturing capability of a camera with the processing power of a computer. They analyze captured images to collect data for inspections or to activate other devices. Based on criteria established during training, vision sensors search for specific features to detect anomalies in parts or processes, thereby automating decision-making and quality control activities.
