First of its kind! GigE Frame Grabber

A GigE frame grabber? What’s that about? Those who work with Camera Link or CoaXPress cameras need frame grabbers for frame transfer, but GigE?

Frame grabbers use an industry standard PCI Express expansion bus to deliver high speed access to host memory for images. They get the image from the camera, via the cabling and frame grabber, at high speed, into the host, for processing.

But I already do GigE Vision without this so why might I want one?

  • Avoid corrupted images arising from lost packets
  • Reduce CPU load
  • Synchronize images from multiple cameras
  • Perform color conversion in the frame grabber rather than the host

The full name of DALSA’s GigE frame grabber series is Xtium2-XGV PX8. It’s available in both dual and quad configurations, as shown in the image below.

More than an adapter card

The Xtium2-XGV PX8 image acquisition cards use a real-time depacketization engine to create a ready-to-use image from the GigE Vision image packets. With packet resend logic built in, image transfer reliability is enhanced. And host CPU load is reduced. So already we see two benefits.

But wait there’s more!

Supporting up to 32 cameras, these boards aggregate input bandwidth of 4 GByte/s and up to 6.8 GBytes/sec output bandwidth to the host memory. They can also perform on-board format conversions like Bayer to RGB, Bi-color to RGB, etc.

So it’s really an “Aggregator-conditioner-converter-pre-processor”

Exactly! Which is why we call it a frame grabber for short.

Psst! Wanna see some specs?

So do you need one or want one?

So an Xtium2-XGV PX8 frame grabber is an aggregator-conditioner-converter-pre-processor. It accepts multi-port GigE Vision inputs, improves reliability, optionally does format conversions, and reduces load on the host PC. If your prototype system is struggling without such a frame grabber, maybe this is the missing link. Or maybe you want to get it right on the first try. Either way, tell us more about your application, and we’ll help you decide if this – or some other approach – can help.

Automation Technology Solution Package

Automation Technology GmbH, or AT for short, is a leading manufacturer of 3D laser profilers, and also infrared smart cameras. As customary among leading camera suppliers, AT provides a comprehensive software development kit (SDK), making it easy for customers to deploy AT cameras. AT’s Solution Package is available for both Windows and Linux. Read on to find out what’s included!

Overview

AT’s Solution Package is designed to make it easy to configure the camera(s), prototype initial setups and trial runs, proceed with a comprehensive integration, and achieve a sustainable solution.

cxExplorer

Configuration of a compact sensor can be easily done with the cxExplorer, a graphical user interface provided by AT – Automation Technology. With the help of the cxExplorer a sensor can be simply adjusted to the required settings, using easy to navigate menus, stepwise “wizards”, image previews, etc.

APIs, Apps, and Tools

The cxSDK tool offers programming interfaces for C, C++, and Python. The same package work with all of Automation Technologies 3D and infrared cameras.

Product documentation

Of course there’s documentation. Everybody provides documentation. But not all documentation is both comprehensive and user-friendly. This is. It’s illustrated with screenshots, examples, and tutorials.

Metrology Package

Winner of a 2023 “inspect” award, the optional add-on Metrology Package can commission a customer’s new sensor in just 10 minutes, with no programming required. Then go on to create an initial 3D point cloud, also with little user effort required.

TCSE series hi-res telecentric lenses

Opto Engineering is known and respected for high-performance lenses in machine vision, medical, and related fields. The new TCSE series are telecentric lenses designed for large sensor formats (4/3″, APS-C, APS-H). Each provides high resolution with low distortion.

Who needs a telecentric lens?

Before inviting you to some of the TCSE series features, let’s offer readers who aren’t already telecentric-savvy a brief motivation for this category of lens. If you are doing precise gauging applications – measuring via optics and software – your tolerances may require a telecentric lens. A telecentric lens eliminates perspective error. They have very low distortion. And, if paired with collimated light, they enhance edge definition.

For a comprehensive read, check out our blog Advantages of Telecentric Lenses in Machine Vision Applications. Not sure if you need a telecentric lens? Call us at 978-474-0044 – tell us a little about your application and we can guide you through any or all of lens, camera, lighting and other choices.

TCSE lenses are available for applications using light in either the visible spectrum or near-infrared (NIR) wavelengths. Currently there are 8 members in the TCSE product family.

Image circle diameter

The TCSE Series offers image circle diameter options from 24 – 45mm.

Magnification

A key parameter in telecentric imaging is the level of magnification available. The 8 members of the TCSE Series offer magnification ranging from 0.36 through 2.75 times the original object size.

Working distance

The working distance (WD), from the front of the lens to the object being imaged, varies by lens model across the TCSE Series. The shortest WD offered is 160mm, spanning distances up to 240mm. These long working distances allow space for lighting and/or robotic arms.

Worth noting

While typically “plug and play” once mounted on your camera, it’s worth noting that the TCSE lenses offer back focal length adjustment, should one choose to fine tune.

Summary

Telecentric lenses are the core business for Opto Engineering, who have more than 20 years expertise in research, development, and production. 1stVision, North America’s largest stocking distributor, works to understand each customer’s application requirements, to help you select the ideal lens, camera, or other imaging component(s).

Teledyne DALSA AxCIS Contact Image Sensor Modules

Teledyne DALSA has released the AxCIS 800mm mono/HDR, and the AxCIS 400mm mono, the first two members of a new flexible and scalable product family of Contact Image Sensors (CIS). As other members are released, users can choose fields of view (FoV) in 100mm increments, e.g. 400mm, 500mm, 600mm, 700mm, and 800mm.

Contact Image Sensor vs. Linescan

Actually that’s a trick heading! A contact image sensor (CIS) is a type of linescan camera. Conventionally, the industry calls it a linescan camera if the sensor uses CMOS or CCD. while it’s called a CIS if it bundles a linear array of detectors, lenses, and lights.

But CIS is very much a linescan type of camera, With a 2D area scan camera, a comprehensive pixel array captures hundreds or thousands of (X,Y) values in a single exposure. But a Contact Image Sensor requires either the target or the imaging unit to move, as a single exposure is a slice of Y values at a given coordinate X. Motion is required to step across the set of X values.

Two more notes:

  1. The set of X values may be effectively infinite, as with “web inspection” applications
  2. The term “contact” in CIS is a bit of a misnomer. The sensor array is in fact “very close” to the surface, which must thereby be essentially flat in order to sustain collision-free motion. But it doesn’t actually touch.

AxCIS key attributes include:

  • 28um pixel size (900dpi)
  • high speed 120KHz using Camera Link HS
  • HDR imaging with dual exposure mode
  • optional LED lighting
  • fiberoptic cables immune to EMI radiation

Application areas share the characteristics of flat surfaces and motion of either the target or the sensor, since contact image sensing (CIS) is a form of linescan imaging.

HDR imaging

Some targets are inherently challenging to obtain sufficient saturation for the darker regions while avoiding over-saturation for the lighter areas. The multiline sensors used in AxCIS utilize a sensor array with:

  • One row of the sensor array that can have a longer exposure for dark scenes
  • Another row using a shorter exposure for light scenes

The camera then combines the images, as shown below. The technique is referred to as High Dynamic Range imaging – HDR.
