Vision sensors can be used in industrial production, quality control and logistics and can, for example, check the position and size of circuit boards and components before they are packaged. Likewise, they can be used in object recognition and pattern recognition. Vision sensors are also used in safety engineering and surveillance technology.
Vision sensors consist of a camera module with a relatively low resolution ofVGA or below, a dedicated imagesignal processor( ISP) with corresponding firmware, a ROM memory and a working memory, a USB interface and an Ethernet interface. The operation and adjustment capabilities of vision sensors are relatively limited. This is due to the fact that vision sensors are configured for specific applications.
