Smart Cameras for Embedded Machine Vision
NI 1744 Smart Camera – Uses the same 533 MHz processor as the
NI 1742 but features a higher-resolution CCD that acquires images of
1.3 megapixels (1280x1024); with higher resolution, you can inspect
objects for smaller defects and make measurements with four times the
resolution of previous NI Smart Cameras.
Camera Comparisons
National Instruments offers a variety of smart cameras to meet a
breadth of machine vision application needs.
All NI Smart Cameras process images using onboard PowerPC
processors. In higher-performance models, a Texas Instruments digital
signal processor (TI DSP) acts as a coprocessor to boost the performance
of specific algorithms. The image sensors inside all NI Smart Cameras
are charge-coupled devices (CCDs).
NI 1762 Smart Camera – Offers a 720 MHz TI DSP coprocessor
alongside the 533 MHz PowerPC, making it possible to run specific
algorithms up to four times faster with no changes to the application
software (works well for engineers needing higher performance for
pattern matching, optical character recognition, and datamatrix code
reading); contains the same VGA resolution (640x480) image sensor
found in the previous NI Smart Cameras.
NI 1722 Smart Camera – Powered by a 400 MHz PowerPC processor;
features a VGA (640x480) resolution CCD image sensor that can acquire
images up to 60 fps.
NI 1742 Smart Camera – Powered by a 533 MHz PowerPC processor;
NI 1764 Smart Camera – Provides the 1.3 megapixel image sensor
found in the NI 1744, and the 720 MHz TI DSP coprocessor found in
the NI 1762; ideal for high-speed manufacturing.
acquires VGA resolution (640x480) monochrome images at up to 60 fps.
