TECH FOCUS: EMBEDDED VISION
Does embedded have the edge?
A round-up of some of the latest cameras, modules and other embedded vision technology on the market
I
n some respects, the industrial vision market has provided embedded vision products for
many years – from smart cameras to self-contained vision devices with onboard image processing. A new wave of products now follows the development of computer
processors powerful enough to run vision algorithms, board-level system-on-modules from NXP, for example, or GPUs and FPGAs. Embedded computer hardware
is small, inexpensive, powerful and energy-efficient. Some chips are being designed specifically to work with neural networks. Attaching a sensor module brings image processing closer to the sensor; this is known as ‘edge processing’, as opposed to processing in the cloud or sending the feed from the camera to a separate computer. Embedded computing opens
the door to many more uses of vision technology. Even in

factories where machine vision is already established and successful, there are areas where embedded vision can play a role. Te downside to developing
products on embedded boards is that integration complexity and cost is higher in a relatively new market. Te Khronos Group, together with the European Machine Vision Association, is working on an open API standard for controlling embedded cameras across mobile, industrial, XR, automotive and scientific markets. Tis new standard aims to help companies building embedded vision devices. Te design of the API is making significant progress and will include loadable layers and multiple language bindings as well as flexible, low-level control over camera functionality.
Thirty years building grabbers and still launching new stuff. Today, Bitflow brings you the Claxon Fiber, a frame grabber capable of CXP12 over fiber. Our frame grabber interfaces are Camera Link, CoaXPress, and Differential. We offer several options with each interface to ensure you get exactly the board you need at the right price. These boards can be embedded into a rack system to
ensure you are getting the full bandwidth of 50 Gb/S of data. BitFlow’s low-level diagnostics will ensure you know why you are getting every pixel delivered as it should be into your processing software. No one else offers this option. Our software is some of the easiest to use, yet incredibly powerful and reliable. Windows, and Linux (regular and Aarch64) options are available. Choose the best. Choose BitFlow.

Commercial products Vendors offering products for embedded vision include Advantech, which recently released the AIMB-522, an industrial Micro-ATX motherboard for AI image processing in automation and surveillance. AIMB-522 leverages AMD’s desktop processor, the Ryzen Embedded 5000, which provides 16 high-performance Zen 3 cores. Te motherboard also features several technologies designed to empower efficient high-performance computing. Tese include PCIe Gen 4 expandability, 4 x Gigabit Ethernet ports, and 8 x USB 3.2. Tis combination of features and functions produces an excellent solution for factory automation, smart logistics, and intelligent surveillance applications. Congatec offers 12th-
generation Intel Core mobile and desktop processors (formerly Alder Lake) on 10 of its COM-HPC and COM Express computer-on-modules.

COM Express type six form factors and the modules in COM-HPC size A and C provide major performance gains and improvements based on Intel’s performance hybrid architecture. Basler’s latest addition is a
range of add-on camera kits with 5 and 13 megapixels to support the Nvidia Jetson Orin Nano system-on-modules, for entry-level edge AI and robotics. Te kits are ready-to-use vision extensions that include an adapter board, camera, lens, and cables. Te Basler Camera Enablement Package is designed to enable smooth integration of its Camera Software pylon with the Nvidia JetPack software development kit. A Camera Enablement Package includes a Basler camera kernel driver, device-tree overlays for the supported boards, GenTL Producer and the pylon Viewer application. Framos offers a range of
fully embedded solutions for OEMs, industrial customers and users. Te company recently launched the FSM-IMX547 Camera Accessory for the Kria KR260 Robotics Starter Kit from AMD (also recently introduced). Te FSM-IMX547 is capable of streaming high-quality colour or monochrome images to the Kria KR260 robotics starter kit. Fully integrated, the camera kit is compatible with the 10GigE Vision Camera App, available for free evaluation and download at the AMD-Xilinx App Store. It is designed to allow developers to design their own high- performance, high-speed, and high-resolution machine vision applications. Gidel recently added the
Nvidia Jetson Orin NX 16GB system-on-module to its FantoVision range of high- bandwidth compact computers for vision on the edge. Paired
