Overview
NI 17xx Smart Cameras simplify machine vision by analyzing images directly
on the camera with a powerful, embedded processor capable of running
the entire suite of NI vision algorithms. You can use these cameras in a
variety of applications including part location, defect detection, code
reading, and assembly verification. The combination of the onboard
processor with a charge-coupled device (CCD) image sensor provides an
easily distributed, all-in-one vision system that transmits inspection
results along with or in place of raw images. Housed in a rugged metal
case designed for use in industrial applications, all NI Smart Cameras
offer built-in I/O, multiple industrial protocols, built-in Web servers, and
many other features. You can configure NI Smart Cameras with the
included NI Vision Builder for Automated Inspection (AI) software or
program the camera with LabVIEW Real-Time.
logic controllers (PLCs), or with human machine interfaces (HMIs). All
NI Smart Cameras include an RS232 serial port and 5 and 24 V lighting
strobe outputs that you can use for synchronization with third-party
lighting controllers.
NI Smart Cameras, with the exception of the NI 1722, include quadrature
encoder support for synchronizing inspections with linear and rotary drive
systems. This feature simplifies timing in complex applications where
consistency is critical to system success.
Direct Drive Lighting
To directly illuminate objects under
the camera, NI Smart Cameras
feature direct drive lighting. Lighting
controllers can be costly additions
to machine vision applications.
NI Smart Cameras have a built-in
lighting controller so you can directly
drive lights from the camera itself,
lowering costs and simplifying wiring. The built-in direct drive lighting
controller can provide a constant DC current of 500 mA or a strobed
current of up to 1 A. With strobed lighting, you can increase the intensity
produced by up to four times without harming the light head. Most current-
driven LED light heads work with the NI Smart Camera’s direct-drive
feature (this feature is not included on the NI 1722).
Flexible Industrial I/O
To communicate results to other industrial devices, NI Smart Cameras
offer built-in digital I/O and support both Ethernet- and serial-based
industrial protocols such as Modbus TCP. NI Smart Camera digital I/O
lines are optoisolated for direct connectivity with industrial devices such
as triggers and actuators. All NI Smart Cameras offer two optoisolated
digital inputs and two optoisolated digital outputs.
To simplify Ethernet-based communication, NI Smart Cameras include
two gigabit Ethernet ports. With one port connected to an industrial
network to report inspection results, the other port can directly communicate
with programmable automation controllers (PACs) such as NI CompactRIO
or Compact FieldPoint, with industrial devices such as programmable

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.
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 1764 Smart Camera

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).

to compact vision systems to the sensor itself with NI Smart Cameras. This
entire range of hardware works with both LabVIEW and Vision Builder AI.
This means you can design and prototype your machine vision algorithms
using an off-the-shelf machine vision camera connected to an NI frame
grabber and deploy that same application to an NI Smart Camera with
minimal changes to your LabVIEW code or Vision Builder AI inspection.
Figure 1. With the scalability of NI vision software, you can develop your code on a PC,
prototype on an NI Compact Vision System, and deploy to an NI Smart Camera without
ever changing your application development environment.

Smart Cameras for Embedded Machine Vision
National Instruments vision software includes hundreds of image
processing and analysis functions. A subset of the tools available in the
Vision Development Module and Vision Builder AI are shown below.
Pattern and Geometric Matching
Bar Code Reader and Grader
Learn and locate objects and patterns in your
images. The National Instruments patented
matching algorithms locate patterns fast with
very high accuracy.
Optical Character Recognition/Verification
Read 1D bar codes as well as 2D codes like Data
Matrix and PDF 417. You can decipher codes
applied through ink jets, thermal transfer, laser
etching, or dot peen.
Spatial Calibration
NI OCR functions use a trainable OCR algorithm
specifically designed to identify and verify all
types of fonts, characters, and symbols despite
poor and inconsistent image quality.
Particle Analysis
Using spatial calibration functions, you can
calibrate your image to take accurate, real-world
measurements from images, regardless of camera
perspective or lens distortion.
Image Arithmetic and Logic Functions
Use particle analysis to detect connected regions
or groupings of pixels in an image and make
selected measurements of those regions. Choose
from more than 80 unique measurements that
return data in both real-world and pixel values.
Color Inspection
Operators perform basic arithmetic and logical
operations on images. Use operators to add,
subtract, multiply, and divide an image with other
images or constants.
Coordinate Systems
Color matching quantifies which colors and how
much of each color exist in a region of an image
and uses this information to check if another
image contains the same colors in the same ratio.
Edge Detection
Set up coordinate systems to ensure that all your
measurements move with the object within the
field of view.
Image Filters and Frequency Analysis
Use the edge detection tools to identify and locate
discontinuities in the pixel intensities of an image.
Find edges to align, measure, or detect features in
the image.
Object Classification
Frequency filters, such as the fast Fourier
transform (FFT), alter pixel values with respect to
the periodicity and spatial distribution of the
variations in light intensity in the image.
Image Segmentation
Classification is a tool for identifying an unknown
object by comparing its significant features to a
set of features that represent known samples.
NI vision software comes with several options to
segment and partition images into related components.
Segmentation is an important part of many imaging
applications that need to extract certain features or
objects in order to process them further.
Golden Template Comparison
Gauging
Use dimensional measurement or gauging tools to
obtain quantifiable, critical distance measurements
such as distances, angles, areas, line fits, circular
fits, and counts.
Find defects in an image by comparing a perfect
(golden) sample to all subsequent samples. Golden
template comparison detects surface defects, label
misprints, and overall quality issues.

Expansion I/O and HMIs
If your applications need more I/O than NI Smart Cameras provide, you can
easily connect expansion I/O over standard Ethernet. Compact FieldPoint
and CompactRIO are two popular NI platforms for expansion I/O. Both
of these platforms are built on real-time architectures, ensuring the
determinism needed for many industrial applications. CompactRIO also
features a built-in field-programmable gate array (FPGA) for precise timing
and synchronization. Communication to both of these platforms is simplified
with the use of shared variables in LabVIEW or Vision Builder AI. For
more information on these platforms, visit
ni.com/compactfieldpoint
or
ni.com/compactrio.
For interfacing options, NI offers a full suite of touch panel HMIs.
With the LabVIEW Touch Panel Module, you can develop custom HMI
applications for Windows CE touch panel devices. Other options include
Windows XP HMI devices that can run the entire LabVIEW development
environment. Or simply target NI Smart Cameras and other PAC devices
through a Web browser with the Web server technology available on
these hardware platforms. For more information on HMI options from
NI, visit
