A smart camera or intelligent camera is a machine vision system which, in addition to image capture circuitry, is capable of extracting application-specific information from the captured images, along with generating event descriptions or making decisions that are used in an intelligent and automated system. A smart camera is a self-contained, standalone vision system with built-in image sensor in the housing of an industrial video camera.It contains all necessary communication interfaces, e.g. Ethernet, as well as industry-proof 24V I/OP lines for connection to a PCL, actuators, relays or pneumatic valves. It is not necessarily larger than an industrial or surveillance camera. A capability in machine vision generally means a degree of development such that these capabilities are ready for use on individual applications.
This architecture has the advantage of a more compact volume compared to PC- based vision systems and often achieves lower cost, at the expenses of a somewhat simpler (or omitted) user interface. Teledyne DALSA has a separate intelligent product division for many machine vision applications addressed by smart cameras with built in image processing and Machine Vision algorithms. Teledyne DALSA makes small, flexible and smart cameras providing smart vision for all machine vision applications in the field of automation.
Applications include positioning, identification, verification, measurement, flaw detection etc. Offline verification audits, robot guided pick and place, positioning tools are critical to successful machine vision. Positioning tools, locators or pattern finders recognize and determine exact position and orientation of parts in Machine Vision applications. Results can be transferred directly to material handling devices or used to position other tools required for the inspection.
Identification encompasses a range of machine vision applications that involve reading printed characters and decoding 1D or 2D symbols on products or parts. For traceability of production parts, verification of product lots or grading of print codes, DALSA's Identification tools are designed for accurate results in the toughest of manufacturing environments. Machine Vision systems are widely used for verification of parts, assemblies and packaged goods.
The range of verification applications are generally so broad, they utilize the same tools for positioning, measurement, identification and flaw detection. Verification is often combined with other tasks, such as measurement of part dimensions or reading of product barcode, to render 100% product inspection. Manufacturing requirements for measurement range from presence verification to checking high-precision dimensional accuracy and geometrical tolerances.
Attention to the inspection environment and image quality is as important as the vision algorithms themselves. DALSA sub-pixel measurement tools, combined with the right optics and stable lighting, provide the precision and repeatability to ensure manufacturing accuracy.
