Machine Vision Standards - Interchangeability or Compatibility?

The emergence of machine vision standards has led to the industry agreeing on cooperation in an unprecedented way. This should simplify and shorten the design-in phase for cameras in machine vision applications with the aim of cutting development costs.


Interchangeability and complete plug & play functionality of devices are always emphasized as key features. But are these the crucial factors for implementing an application? Is a totally generic solution for every application the right way? It really depends. For manufacturers, the desired objective thus tends to be “increased compatibility”, which is achieved automatically by using the standard vision protocols.

Stay connected with USB 3.1 - The next generation standard camera interface

In previous generations USB was only a data interface, capable of supporting limited power for a device. With the USB 3.1 specification the USB implementers forum (USB-IF) has reworked also other sections.
The most significant improvement is the new USB Type-C connector which put an end to the plug confusion and should become the new standard. But what are the innovations of USB 3.1 and what are the benefits for USB as a camera interface?
Switch to USB 3.0 industrial cameras from IDS

Don't lose your connection - Why it makes sense to switch to USB 3.0 now

In industrial environments, everything revolves around reliability, productivity and stability. Processes and equipment are subject to numerous certifications. Changes are planned and tested well in advance. No-one allows themselves to be dazzled by the limitless possibilities of technologies that are still in their infancy. And a healthy dose of skepticism towards new things is par for the course. In any case, the optimization of processes and workflows can best be planned using known technologies.
But how do you know when a technology is really ready to be deployed? At what point can you be sure there's no risk you may actually be sitting on a ticking technology time bomb? And, until that point arrives, is the best strategy to sit back and wait? But just think, where would we be today if we had never allowed ourselves to get on board with new technologies? How can we bring about a fourth industrial revolution by sticking to what's been tried and tested and resting on the incomplete knowledge of others?

Obtaining Depth Information from Stereo Images

This paper gives an overview of the main processing steps for depth perception with a stereo camera. After a description of the general techniques, we discuss the specifics of the Ensenso N10 stereo camera in combination with the NxLib stereo processing library.

High Dynamic Range Imaging: Images and Sensors

In the past, technological development in the image sensor field primarily strove to increase resolution by adding pixels. The current generation of digital cameras already offer resolutions over 10 Megapixels. This allows details too small to be seen with the human eye to be im-aged, provided the optics are up to the task. With regard to dynamic range, however, human sight is far superior to conventional image capturing devices. If a scene contains very bright and very dark areas, a camera will quickly reach its limits. While the eye can perceive all brightness levels, image sensors suffer from overexposure and therefore lose image data. HDR (High Dynamic Range) technology, on the other hand, enables fine differences in bright-ness to be imaged even in very bright scenes, similar to the human eye. This white paper ex-plains the background behind HDR technology and the method of functioning of HDR image sensors. Finally, potential uses and limits of the new technology will be identified.

USB 3.0 - Background Factors, New Features, and Applicability as a Camera Interface

USB 3.0 - Background Factors, New Features, and Applicability as a Camera Interface

In November 2008, the specification for "SuperSpeed USB" was presented and marked an improved and, above all, considerably faster version of the popular interface. New features on the protocol level as well as on the hardware side promise to eliminate some of the limitations imposed by version 2.0. This article presents the main characteristics of USB 3.0 as well as its benefits when used as a camera interface for image processing.
