With the B&R vision system, there's no more need for additional settings on the machine. It's plug and run. Usually, after a project is finalized in an engineering tool, developers have to adjust all settings directly on the machine in a second step. B&R calibrates vision systems, including all lighting elements, prior to delivery. This allows developers to test and verify their application at any time and from any location, without having to be physically present at the real machine.

Several exceptional features characterize our machine vision solution. The relation of processing power to camera size and cost is extraordinary. A few years ago, the industry could only dream of this kind of performance with such a compact camera. By combining multiple functions in one housing, machine builders and end users can save time and money.

Intelligent lights that can seamlessly adapt to your products in real-time, allow you to unveil the invisible. Each light can feature up to four different LED colors. The selection ranges from white and various visible colors to invisible colors. Infrared or ultraviolet LEDs can be used to make structures disappear or become visible.

The unprecedented depth of integration of B&R's vision system opens up new possibilities that go far beyond quality inspection. Information can be fed into control loops in real time to provide advanced machine control. This allows deterministic system behavior that leads to minimum machine downtimes and in the end a maximum OEE. Central data management enables detailed diagnostics and easy maintenance.

By integrating HALCON program code into an intuitive user interface, the vision functions make it easy for automation programmers to configure modern image processing functions and integrate the results into the machine application. Image processing is more flexible and productive than ever.

Both the hardware and software of B&R's vision solution are fully integrated in the control system. This is the only way to achieve absolute precision and microsecond synchronization between all automation components – including machine vision. With only one engineering tool and one application to manage, controls engineers will now be able to implement many machine vision tasks on their own.

By using complementary lighting in different applications, maximum intensity and contrast can be achieved. At the same time, the right color combination ensures minimum exposure time and smearing.

A Single Wire Daisy Chain connection enables fast cost-efficient wiring for B&R’s vision system. Cable lengths are minimized without requiring additional space in the control cabinet. During maintenance, there's no need for an additional trigger line.

Unlike conventional image processing systems, the B&R vision system can therefore also be used in high-speed applications without any problems. We recently realized an application where the system reads a data matrix code on a band saw blade at 56 m/s speed. Also, the high-performance lighting eliminates almost entirely the influence of extraneous light - a crucial quality factor.

As the only manufacturer on the market, B&R equipped its light bars with electronic angle adjustment from -45° to +90°, via the fieldbus connection. When producing multiple products on the same machine, the lighting angle can be automatically and reliably optimized for each batch.

Unlike many other devices in its class, there is no need to install different sensors for different functions. Instead, users simply configure the Smart Sensor in the Automation Studio engineering tool, where they can choose from a large selection of functions. Up to 255 models can be stored and executed on a sensor. Additional models can easily be exchanged in the software.

B&R calibrates all lighting elements and optical systems – consisting of lens, sensor and focus adjustment – prior to delivery. As a result, there are no parameter or programming changes required when devices are exchanged in the field.

Both the hardware and software in B&R's vision solution are fully integrated in the control system. This is the only way to achieve absolute precision and microsecond synchronization between all automation components, including machine vision. The system can be connected with an axis in just a few clicks.

Getting a vision system up and running doesn't require complex programming skills. Engineers can easily program, parameterize and even simulate image processing in the Automation Studio engineering tool even without having to compile the entire project. Additionally, the ability to export test results to Excel helps to optimize the process and generate quality related data such as standard deviation.

Deep learning-based anomaly detection identifies even the smallest deviations in structure with high reliability. This detection technology has already been successfully tested for automatic quality control of wooden surfaces, textiles, welding joints and more.

Machinevision

Unlike other deep learning methods, it requires no dedicated labelling of different defect classes. In most cases, around 100 good images are sufficient to train the network. During inference, anomaly detection segments the regions of the images that differ significantly from the training images.

The integrated character recognition function has an exceptional capability to instantly recognize characters. There’s no training or parametrization necessary to enable high-speed reading even with poor image quality or difficult characters, such as dot matrix fonts. A deep learning algorithm makes the function even more reliable and opens up exciting new ways to improve quality, boost productivity and prevent rejects - all while making manufacturing more flexible. All available smart camera features can be combined with deep OCR.

Each vision sensor or camera can be configured individually – fully adapted to the machine process. It's possible to customize your order to your needs starting by deciding between a sensor, camera or deep learning camera. From there, you can choose from a wide range of focal lengths, illumination colors and many more variants.

With the B&R Flash Controller, any external current-driven lighting system works as if it were an integrated B&R Smart Light. This system offers single-wire connections without needing additional trigger sensors. It provides µs-accurate synchronicity to the entire B&R system, incredibly fast flash current rise times and maximum power during the entire flash period. What's more, costs are saved due to reduced cabinet space, fewer cables and shorter cable lengths.
