VISION SYSTEM BASED ON A SINGLE-CHIP MICROCOMPUTER

The paper describes a compact and inexpensive binary vision system in which all interfacing and data processing functions are performed by an Intel 8751 single-chip microcomputer. The vision sensor is a 64 kbit dynamic RAM chip which is capable of providing a picture resolution of up to 256 multiplied by 128 pixels. Picture processing algorithms are implemented within the vision system and object statistics are transferred to the host computer over a serial interface. The resulting system is implemented using only four integrated circuits and is eminently suitable for component identification and inspection in a flexible manufacturing system environment.
