Automated Vision Inspection Machines – Just Released..

Machine vision (MV) is the technology and techniques used to provide imaging-based automatic inspection and analysis for such applications as automatic inspection, process control, and robot guidance, usually in industry. Machine vision refers to many technologies, software and hardware products, integrated systems, actions, methods and expertise. Machine vision as a systems engineering discipline can be looked at distinct from computer vision, a kind of computer science. It tries to integrate existing technologies in new ways and apply them to solve real life problems. The phrase is the prevalent one for these functions in industrial automation environments but is also used for these functions in other environments like security and vehicle guidance.

The entire Top Machine Vision Inspection System Manufacturer includes planning the facts in the requirements and project, and after that creating a solution. During run-time, the process starts off with imaging, accompanied by automated research into the image and extraction in the required information.

Definitions in the term “Machine vision” vary, but all range from the technology and techniques used to extract information from a picture with an automated basis, instead of image processing, where the output is yet another image. The data extracted can be a simple good-part/bad-part signal, or even more a complex set of web data such as the identity, position and orientation of each object in an image. The data can be utilized for such applications as automatic inspection and robot and process guidance in industry, for security monitoring and vehicle guidance. This field encompasses a lot of technologies, software and hardware products, integrated systems, actions, methods and expertise. Machine vision is actually the sole expression used for such functions in industrial automation applications; the phrase is less universal for these particular functions in other environments such as security and vehicle guidance. Machine vision as a systems engineering discipline can be regarded as distinct from computer vision, a form of basic computer science; machine vision efforts to integrate existing technologies in new ways and apply them to solve real-world problems in a way that meets the prerequisites of industrial automation and similar application areas. The word is additionally used in a broader sense by trade events and trade groups such as the Automated Imaging Association and the European Machine Vision Association. This broader definition also encompasses products and applications most often associated with image processing. The key uses for machine vision are automatic inspection and industrial robot/process guidance. See glossary of machine vision.

Imaging based automatic inspection and sorting

The primary uses for machine vision are imaging-based automatic inspection and sorting and robot guidance.;:6-10 in this section the former is abbreviated as “automatic inspection”. The general process includes planning the facts from the requirements and project, then creating a solution. This section describes the technical process that occurs during the operation of the solution.

Methods and sequence of operation

Step one in the automatic inspection sequence of operation is acquisition of an image, typically using cameras, lenses, and lighting that has been made to provide the differentiation necessary for subsequent processing. MV software packages and programs developed in them then employ various digital image processing strategies to extract the necessary information, and frequently make decisions (like pass/fail) based on the extracted information.


The components of the automatic inspection system usually include lighting, a camera or any other imager, a processor, software, and output devices.3


The imaging device (e.g. camera) can either be separate from the key image processing unit or coupled with it where case the combination is usually known as a smart camera or smart sensor When separated, the bond may be made to specialized intermediate hardware, a custom processing appliance, or a frame grabber inside a computer using either an analog or standardized digital interface (Camera Link, CoaXPress) MV implementations also have digital cameras competent at direct connections (with no framegrabber) to a computer via FireWire, USB or Gigabit Ethernet interfaces.

While conventional (2D visible light) imaging is most frequently found in MV, alternatives include multispectral imaging, hyperspectral imaging, imaging various infrared bands,line scan imaging, 3D imaging of surfaces and X-ray imaging. Key differentiations within MV 2D visible light imaging are monochromatic vs. color, frame rate, resolution, and whether the imaging process is simultaneous on the entire image, rendering it suitable for moving processes.

Though the majority of machine vision applications are solved using two-dimensional imaging, Automated Vision Inspection Machines utilizing 3D imaging certainly are a growing niche inside the industry. Probably the most widely used way of 3D imaging is scanning based triangulation which utilizes motion in the product or image through the imaging process. A laser is projected to the surfaces nefqnm an object and viewed from a different angle. In machine vision this can be accomplished with a scanning motion, either by moving the workpiece, or by moving the digital camera & laser imaging system. The line is viewed by a camera coming from a different angle; the deviation in the line represents shape variations. Lines from multiple scans are assembled in to a depth map or point cloud. Stereoscopic vision is used in special cases involving unique features present in both views of a set of cameras. Other 3D methods employed for machine vision are period of flight and grid based.One method is grid array based systems using pseudorandom structured light system as utilized by the Microsoft Kinect system circa 2012.
