Smart Cameras for High Performance Machine Vision Systems		High Speed Intelligent Compact Cameras for Machine Vision Systems



Machine Vision is an electronic alternative to human or manual inspection that helps companies increase productivity and save money by eliminating defective products with 100% accuracy. Used for machine vision, DVT SmartImage Sensors are digital cameras that are small enough to fit in the palm of your hand. What makes these sensors “smart” is an on-board computer processor and a CCD that captures digital images to be inspected at its smallest unit: a pixel. Using DVT’s Windows-based Framework software, features of a product can be evaluated based on criteria such as presence/absence, orientation, size, position, and other specifications. This information can then be reported to direct robots, HMI/SCADA devices, printers or other machines to perform the next step on a production line. DVT is the first company to combine machine vision technology with Ethernet communications so manufacturers can monitor and configure inspections or perform remote diagnostics from any computer with an Internet connection – anywhere in the world! SmartImage Sensors also support serial, Modbus, DeviceNet and Profibus protocols. SmartImage Sensors are simple enough for an operator to maintain, flexible enough for the most demanding applications, and can be integrated onto any existing machine in your facility. DVT also provides free training, free software, licenses and upgrades offering the best value in machine vision.		For over 20 years, PPT VISION has developed innovative machine vision technologies for in-line automated inspection. Now PPT VISION has introduced the industry’s first intelligent camera family with all the features of a full-scale machine vision system - at a fraction of the cost. IMPACT is a family of high-speed intelligent cameras with twice the horsepower of typical industrial smart cameras. It is fully configurable for a broad range of applications with INSPECTION BUILDER software; a programming toolkit containing over 80 powerful inspection tools including measurement, pattern matching, defect detection, character reading, morphology, and much, much more. Inspection tools can be mixed and matched to create a custom inspection solution for the toughest industrial applications. As a bonus, IMPACT is supplied with a complete Human-Machine Interface (HMI) developer's suite for custom deployment on the plant floor – and all this is all accomplished graphically, meaning that knowledge of complex programming languages is not required. With thousands of successful machine vision installations throughout the world – in a broad range of manufacturing applications, PPT VISION is the world leader in machine vision innovation.

Machine Vision Components

Cameras This Category usually consists of one or more cameras and lenses (optics), which take a picture of the part being inspected. Depending on the application, the cameras can be standard monochrome, composite colour, RGB colour, progressive scan or line scan. Optics and Lenses We offer a complete range of video lenses for every scientific, Medical and industrial application. Video lenses from Navitar, Fujinon, Tamron, Computar and Avenir are the ideal choice for applications ranging from PC board inspection to viewing glass bottles on a production line. Lighting Lighting is needed to illuminate the part so that the best possible image can be acquired by the camera. Lighting assemblies cam in various shapes and sizes and are available in a variety of intensities. The most common form of lighting are high frequency fluorescent, LED (Light Emitting Diode), incandescent, and quartz -halogen fibre-optics types. Part Sensor Often in the form of a light barrier or sensor, this device sends a trigger signal when it senses that a part is in close proximity. The sensor tells the machine vision system when a part is in the correct position for an image to be acquired. Frame Grabbers Also referred to as a video capture card, this component is usually in the form of a plug-in board that is installed in the PC. A frame grabber’s job is to interface the camera (or cameras) to the host computer. It does this by taking the image data provided by the camera (in either analog or digital form) and converting it into information for use by the host PC. Inspection Software Machine vision software is used for creating and executing programs, processing incoming image data, and making PASS/FAIL decisions. Machine Vision software can come in many different forms ("C" Libraries, ActiveX controls, Point & Click programming environments, etc.) and can be single function (e.g., designed only for one purpose like LCD inspection, Ball Grid Array (BGA) inspection, alignment tasks, etc.), or multi-function (e.g., designed with a suite of capabilities including gauging, bar code reading, robot guidance, presence verification, etc.) PC Platform The computer is a key element of a machine vision system. For inspection type applications, usually a Pentium III or equivalent is used. In general, the faster the PC, the less time the vision system will need to process each image. Due to the vibration, dust, and heat often found in manufacturing environments, an industrial-grade or ruggerdised PC is often required. Digital I/O and Network Connection Once the system has completed its inspection of a part, it must be able to communicate with the "outside world" to control the manufacturing process, communicate PASS/FAIL information to a database, or both. Usually, a digital I/O interface board and/or network card make up the interfacing through which the machine vision system communicates with the outside systems and databases. Motion Control Solutions Motion control products are designed for powerful; yet simple applications in both point-to-point and advanced multi-axis coordinated motion systems. Servo and step motors are widely used for posuitioning and velocity control in a varety of machine configurations.		How to Plan Your PC-Based Machine Vision System When determining the need for and the implementation of a machine vision system, there are many important factors to consider Machine vision systems (also known to as "automated inspection systems") typically contain a wide variety on components that can directly affect the system's performance.To take full advantage of these powerful systems, and painlessly integrate them into your production line , its best to take some time to learn the basics about what makes up a vision system, how it is implemented, and the importance of proper planning.
