National Instruments Aust & NZ has released a new vision module for the PXI platform that provides a high-performance parallel processing architecture for hardware-defined timing, control and image pre-processing. The new NI 1483 Camera Link adaptor module, in combination with an NI FlexRIO field-programmable gate array (FPGA) board, offers a solution for embedding vision and control algorithms directly on FPGAs. Engineers and scientists can use FPGAs to process and analyze an image in real time with little to no CPU intervention. Additionally, using FPGAs helps eliminate the need to design custom hardware.
Engineers and scientists can use FPGAs to perform operations by pixel, line and region of interest. The FPGAs can implement many image processing algorithms that are inherently parallel, including fast Fourier transforms (FFTs), thresholding and filtering. The NI 1483 Camera Link adaptor modules are ideal for optical coherence tomography (OCT) and high-speed control systems for applications such as laser alignment and sorting. The Camera Link adaptor module are also suitable for acquisition from Camera Link devices with custom tap configurations and high-resolution sensors measuring more than 10 megapixels (MP) requiring hardware-based pre-processing.
The new Camera Link adaptor modules support base-, medium- and full-configuration Camera Link devices as well as 80-bit 10-tap configurations, all up to 85MHz. This design gives engineers and scientists the ability to customize the image acquisition when using custom image sensors. The 85MHz measurement supports the Camera Link standardized specification to its fullest, creating an excellent fit for those working on applications with high frame rates. The Camera Link adaptor modules also integrate several I/O options including four TTL I/O lines, two opto-isolated inputs and one quadrature encoder input in addition to the many modular I/O and industrial communication options available for the PXI platform.
