Scope / Goals
The working group develops specifications for straightforward integration of machine vision systems into production control and IT systems. The scope is not only to complement or substitute existing interfaces between a machine vision system and its process environment by OPC UA, but also to create non-existent horizontal and vertical integration abilities to communicate relevant date to each other authorized process participants, e.g. right up to the IT enterprise level. Therefore, the OPC UA Vision interface exchanges information between a machine vision system and another machine vision system, a machine PLC, a line PLC, or any software system at the control device level accessing the machine vision system.
A machine vision system is any vision system, smart camera, vision sensor or even any other component that has the capability to extract information by digital images or videos for the shop floor or other industrial markets. Digital images or videos represent data in a general sense, comprising multiple spatial dimensions (e.g. 1D scanner lines, 2D camera images, 3D point clouds, image sequences, etc.) acquired by any kind of imaging technique (e.g. visible light, infrared, ultraviolet, x-ray, radar, ultrasonic, virtual imaging etc.). With respect to a specific machine vision task, the output of a machine vision system can be pre-processed images or any image-based measurements, inspection results, process control data, robot guidance data, etc.
