Key Features

Inline FPGA Processing
In an inline FPGA processing architecture, the camera interface is connected directly to the pins of the FPGA; there the pixels are passed directly to the FPGA as they are sent from the camera. This architecture is commonly used with Camera Link cameras because their acquisition logic is easily implemented using digital circuitry on the FPGA. This architecture has two main benefits. First, it offloads some of the work from the CPU to the FPGA by performing preprocessing functions on the FPGA. For example, you can use the FPGA for high-speed preprocessing functions such as filtering or thresholding to preprocess the image before sending it to the CPU, which effectively reduces its workload. It also reduces the amount of data that the CPU must process by implementing logic to capture the pixels from only regions of interest. The second benefit of this architecture is that it enables you to perform high- speed control operations directly on the FPGA without using the CPU. This means that you can use the FPGA to process the image as it is sent from the camera and then make control decisions based on the processing results. An example is high-speed sorting for which you can use the FPGA to send pulses to an actuator that then ejects or sorts parts as they pass by.

Figure 1. Use cases for inline FPGA image processing

In addition to the hundreds of machine vision algorithms included in the Vision Development Module, you can choose from over 50 algorithms specifically for use on NI’s FPGA hardware targets. These preoptimized functions support many different image types. The Vision Development Module also includes the necessary communication and synchronization functions to efficiently transfer images and processing results between the CPU and FPGA.

FPGA-Enabled I/O
With NI Frame Grabbers, you can use FPGAs for more powerful I/O. Frame Grabber Device models that offer user-programmable FPGAs include a prebuilt FPGA personality called Vision RIO. This turnkey IP set allows you to take advantage of FPGA-enabled I/O without ever having to program the FPGA. Without FPGA programming knowledge, you can use Vision RIO to configure a queue of pulses, set line states, and enable hardware-timed IEEE 1588 to provide a reliable, hardware-timed method of synchronizing I/O with visually inspected parts. Using the Vision RIO API, you can configure several different scenarios, including triggered acquisition with multiple encoder- and proximity-controlled ejectors, and manage ejectors controlled with PLC-issued timestamps.

Figure 2. Example of a triggered acquisition scenario with multiple encoder-controlled ejectors

Beyond the Vision RIO API, you can take advantage of the LabVIEW FPGA Module to develop custom, application-specific IP and meet the unique needs of your applications.

Open Camera Connectivity
Unlike some vision component suppliers, NI Frame Grabbers and vision software allow you to choose the camera for your specific application. With support for USB3 Vision, GigE Vision, and Camera Link, you are sure to find the sensor that meets your application needs.

Figure 3. NI Frame Grabbers work with cameras that comply with USB3 Vision, GigE Vision, and Camera Link.

Synchronization Between Other Modules and Devices
Many systems that acquire images with frame grabbers often do more than just image acquisition. Frequently, systems combine image acquisition with motion control, data acquisition, or industrial communication. One of the challenges in integrating different processes is getting them to synchronize and work together. RTSI (Real-Time System Integration bus) is one of the keys to coordinating the motion control, image acquisition, and data acquisition. It is a dedicated high-speed digital bus designed to help systems integrate using low-level, high-speed real-time communication between NI devices. With RTSI, frame grabbers can share high-speed digital signals with data acquisition, motion control, or digital I/O devices without using external cabling and consuming bandwidth on the host bus. For PCI boards, the physical bus interface is an internal 34-pin connector, and signals are shared via a ribbon cable inside the PC enclosure. RTSI cables are available for chaining two, three, four, or five boards together. PXI modules require no cabling at all because the built-in PXI trigger bus handles RTSI functions.

Vision Software

The Vision Development Module includes the following features:

Build High-Performance Solutions – Use hundreds of functions to develop high-performance vision algorithms to run on CPUs and FPGAs.
Choose Your Programming Language – Program your application in LabVIEW, LabWindows™/CVI, and C/C++.
Design Complete Systems – Expand your application beyond just vision. Incorporate motion control, I/O, and HMIs in your design.
Massive Parallelism – FPGAs are parallel in nature, so they are ideally suited for vision applications. Parallelizing your algorithm decreases processing time, reduces latency, and increases overall throughput.
Infinite Customizability – FPGA-based image processing is implemented pixel by pixel, giving you the opportunity to customize your algorithm to meet your exact requirements.
No FPGA Experience Needed – You can develop high-performance FPGA-based vision algorithms the same way you do for a CPU-based design. You do not need to know traditional FPGA design tools.

Vision Assistant
One of the challenges of developing software for machine vision applications is that vision algorithm development is, by its very nature, a repetitious process that requires multiple iterations of testing, adjusting function parameters, and retesting until the software satisfies the application requirements. This can be especially troublesome when using FPGAs for image processing because the traditional approach to FPGA development can slow down innovation due to the compilation times required between each design change of the algorithm. To address this challenge, the Vision Development Module includes a tool called the Vision Assistant.

Figure 6. Developing an algorithm in a configuration-based tool for FPGA targets with integrated benchmarking cuts down on the time spent waiting for code to compile and accelerates development.

The Vision Assistant is an algorithm engineering tool that simplifies vision system design by helping you develop algorithms for deployment on either the CPU or FPGA. It provides a configuration-based approach to building vision algorithms like you can with Vision Builder AI. Load or acquire sample images and see the results of each processing step as it is configured to rapidly prototype your machine vision algorithm. It also provides the necessary benchmarking tools to gauge the performance of the algorithm.

In addition, you can use the Vision Assistant to test the algorithm before compiling and running it on the target hardware while easily accessing throughput and resource utilization information.

Once you are satisfied with your algorithm, you can use the Vision Assistant to generate LabVIEW or C code ready for deployment on your choice of hardware controller. Then you can easily modify the generated code to integrate it with other parts of your system.
