Machine vision explained – What is machine vision?
Machine vision is the method used to digitize the physical world, or capture the three-dimensional representation of the real world, to extract information for decision makings. During the process, hardware devices illuminate and record the data from a “scene,” and software applications or algorithms are deployed to process such information. Read more…
A Comprehensive Guide on How 3D Scanners Work
This comprehensive guide explores the various industrial 3D scanning technologies and their working principles. This article explains the differences between contact and non-contact scanning methods and the most widely used scanning techniques in industrial applications. Read more…
2D or 3D Machine Vision?
Manufacturers can choose either 3D or 2D for their machine vision solution. While 2D machine vision is well known for applications like barcode reading, manufacturers have begun to utilize 3D machine vision to deliver accurate dimensional data, taking application capabilities to a new strategic level.
