Machine Vision: artificial vision in industry

Machine vision is the image analysis and processing technology that allows data and information to be extracted at a digital level. This technology consists of a combination of hardware and software technologies: intelligent cameras and sensors for image capture connected to Industrial PCs capable of receiving and analysing data.

Machine vision systems bring enormous advantages: performing analysis and inspection of objects faster than the human eye, without direct contact. This often leads to an increase in productivity, thanks to the greater accuracy and reliability of quality checks.

Machine vision systems: uses and areas of application

A machine vision system applies to all needs for inspection, control and analysis of products or processes: quality control analysis, optical character or pattern recognition, robot guidance, code reading, positioning checks and 2D or 3D measurements.

Machine vision systems are used in a wide range of industries, for all possible automated production inspection operations: in electronics, automotive, logistics but also in many other sectors such as medical, food and packaging.

MATRICIAL INDUSTRIAL CAMERAS

The matrix camera is an optoelectronic device capable of producing a two-dimensional image of the framed scene. This type of camera can reconstruct a two-dimensional image. The chip that allows the acquisition is solid and usually consists of silicon, and the most used technology in the industrial field is called CCD.

The main difference with a linear camera is in the resolution: linear cameras in fact have a very high spatial resolution. The matrix camera, on the other hand, at the expense of quality, presents a totally different vision of depth and space, providing a better perception of distance and details.

The industrial matrix cameras offered by Digimax comply with CE, FCC, UL and RoHS certifications and guarantee excellent image quality. The most popular features are:

- Operating temperature and stable quality guaranteed;
- The support of the FFC function;
- GigE interface to provide a bandwidth of 1 Gbps and guarantee transmission up to 100m;
- Compliance with GigE Vision V2.0 protocol;
- Support for the GenICam standard;
- Power supply DC 12-24V.

LINEAR INDUSTRIAL CAMERAS

The linear camera consists of sensors placed on a single line. Unlike the matrix one, it, therefore, produces an image consisting of a single line of pixels and the complete image is built on the computer, taking advantage of the movement between the object and the camera.

In this case, the image is decoded by means of an encoder which reconstructs the movement of the object while the camera is fixed, placed at the top of the observation point: the object is scanned by passing it under the 'target. In this way, you will get a very high resolution, a very important feature when it is necessary to do quality control of a particular product (for example during processing).

Digimax's industrial vision and quality control solutions comply with Certifications CE, FCC, UL and RoHS and guarantee excellent quality and processing speed thanks to the possibility of correcting the light field of the target object.

SMART INDUSTRIAL CAMERAS

A Smart Camera is a compact vision system (all-in-one) that contains in a single container a compact camera and a digitalization and image processing system (as well as devices for interfacing with the outside world (communication ports, digital inputs/outputs, video output, etc ...)).

Smart cameras also allow you to develop industrial vision applications without using complex programming languages.

They are perfect for system integrators, machine builders, and research centers for the development of machine vision and industrial automation applications.

One of the main applications is for the recognition of tags and codes such as QR codes or barcodes, which are widely used within the logistics, food and automotive sectors.

3D INDUSTRIAL CAMERAS

The industrial market has developed a strong interest in 3D technology and 3D cameras in recent years. The 3D camera is able to detect scenes and objects in a fast and three-dimensional way, and being free of components, it is robust and not subject to wear.

This advanced technology carefully measures the distance between the sensor and the next surface using time-of-flight technology. The fields in which it is mostly used are those of packaging, storage and handling, airport logistics, robotics, and monitoring of premises and people.

The degree of accuracy is extremely high, while the working distance and field of view are flexibly configurable with natively integrating 3D calibration applications.

In addition to the features already mentioned, the Industrial 3D solutions offered by Digimax guarantee high performance through a high 3D processing speed, high measurement accuracy (5 mm) and a wide range of measurable dimensions.

BOARD-LEVEL INDUSTRIAL CAMERAS

Within the broad market dedicated to machine vision solutions, Digimax proposes a category of devices entirely focused on the creation of embedded cameras on PC boards, the board cameras.

This particular solution offers the user an extreme degree of customisation and is therefore used within particular vision applications.

Discover the best machine vision solutions within embedded systems to develop projects for factory automation and production efficiency.

INDUSTRIAL CAMERAS LENS

The lenses dedicated to machine vision solutions are able to absorb the light spectrum and send the information to the digital sensor used inside the industrial camera.

Machine vision lenses are differentiated according to their use (smart, matrix or linear cameras) and according to the quality they can guarantee and consequently the price; the use of higher quality lenses makes it possible to handle more information as well as higher image resolution.

Another essential feature is the distinction between fixed focus optical systems and industrial lenses that allow adjustment of focal length and field of view.

Lenses used for industrial applications must guarantee certain essential characteristics:

Uniform image quality, thus providing clear and sharp images from the centre to the edges;
Optimised imaging performance even at close range, the minimum object distance is typically 0.1m;
Stable performance in relation to operating temperature, the standard range is -10°C to +50°C;
Low distortion to aid image analysis.

INDUSTRIAL CAMERAS ACCESSORIES

To ensure the quality and performance of a industrial camera, the use of suitable accessories is a prerequisite.

Digimax offers a wide range of accessories dedicated to industrial vision such as professional cables and cabling, cases, connectors and adapters to always express the best possible performance from industrial matrix, linear or smart cameras.

With the development of technology and new solutions dedicated to machine vision applications, the accompaniment of suitable tools and accessories becomes necessary.
