National Instruments (NI) has released a vision module for the PXI platform that provides a high-performance parallel processing architecture for hardware-defined timing, control and image pre-processing.
The NI 1483 camera link adapter 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. It has been developed with an eye tracking solution that can resolve fixation position to within tenths of a degree at up to 500 Hz.
Engineers and scientists can use FPGAs to process and analyse an image in real time with little to no CPU intervention. The FPGAs can implement image processing algorithms that are inherently parallel, including fast Fourier transforms (FFTs), thresholding and filtering.
Ideal for optical coherence tomography (OCT) and high-speed control systems for applications such as laser alignment and sorting, the NI 1483 is 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.
