What is Machine Vision

Machine Vision is an image -based inspection and analysis technology that leverages the harmony between hardware and software to provide solutions for a wide range of applications across industries. Machine Vision covers many technologies, software, hardware products, integrated systems, measures, methods and expertise. Machine Vision (MV) is a technology or method for providing automated imaging inspection or analysis, such as in the application of automated inspection processes, robot control, and industrial control.

Machine vision systems are a series of integrated components that use information from digital images to manage manufacturing and production processes such as ongoing testing and quality controls. Machine vision systems are widely used in various industries and are used to automate mundane and repetitive tasks that become tiresome for human inspectors and operators. They play a role in the automation of assembly, verification and inspection processes, as they are able to position conveyors so that products and materials are required for a particular process.

Industrial image processing is used in a variety of industrial processes such as metal inspection, object recognition, pattern recognition, electronic component analysis, signature and optical sign recognition and currency analysis. The use of machine vision systems enables a 100% inspection of products and parts throughout the process, resulting in improved yields, lower error rates, higher quality, lower cost and greater consistency in the process results.

One or more video cameras are used for analog-digital conversion and digital signal processing. The range of filters that image processing systems use and the image processing methods used. Depending on how image processing is used, this will affect which filters and image processing methods have to be used.

It would be good to work on the definition of image processing to see if it can include not only the software and hardware environment, but also the image recording techniques that need to be applied to the software.

The broadest definition is, for example, that of the AIA (Automatic Imaging Association) which states that “Image processing involves industrial and non-industrial applications where a combination of hardware and software provides operational guidance to devices to perform their functions based on image acquisition and processing. Searchenterprise.ai gives a narrower definition of machine vision, saying that “machine vision is the ability of a computer to see and one or more video cameras are used for analog to digital conversion (ADC) and digital signal processing (DSP). In this respect, machine vision differs from computer vision, which appears in most books on the subject as a possible field of design and software, with much attention paid to integrated image processing systems, while modern books on computer vision say a great deal about the unpleasant realities of seeing such as noise elimination and occlusion analysis.

The primary areas of application of the technology are image-based automatic inspection, sorting and robot guidance. The information can be used in applications such as automated robot inspection, process control, industry safety monitoring and vehicle control.

This broad definition includes products and applications related to image processing. In both industrial and non-industrial applications, the combination of software and hardware works together to enable machine vision systems. Consider how this works and how machine vision systems are used to inspect products and manufacturing processes as common examples of machine vision system practice.

Some manufacturers use vision systems instead of human inspectors because they get faster, more consistent and do not tire. Computer Vision can also be used as part of a larger machine system if required.

A lens collects light that is reflected or transmitted by the part to be inspected to form an image on the camera sensor. A camera takes a digital image and analyzes it based on a predefined criteria catalog. A suitable lens enables you to see the desired field of view and to set the camera at a convenient working distance from the part you are inspecting.

Smart vision sensors are a cost-effective solution for datalogical vision systems and offer a range of options that enable you to choose what options you need without having to pay for features that may never be used. Multi-camera connections and support for 100% inspection are tools to solve some of the most difficult vision applications.

Networking with Industry 4.0 devices enables intelligent cameras to communicate with automation devices without plugging computer vision technology into the camera. On the machine side, component development offers improved raw materials such as a larger variety of cameras that can be used to create specific imaging solutions, new lenses for complicated robotics and much more.
