Vision Software library for vision |
|
| The National Instruments Vision Development Module is for scientists and engineers who develop machine vision and scientific imaging applications. The new package Vision Development Module contains: IMAQ Vision for LabVIEW or LabWindows, Vision Assistant and NI-IMAQ 3.0. | ||||||
| Vision Assistant
is an interactive environment for developers who need to prototype vision
applications quickly without programming, and IMAQ Vision, a library of
powerful functions for image processing. Unlike any other vision products,
NI Vision Assistant and IMAQ Vision work together to simplify vision software
development. NI Vision Assistant can automatically generate a LabVIEW block
diagram that contains the same functionality as the series of operations
you prototyped in NI Vision Assistant. You can integrate the diagram into
your automation or production test application, which can include motion
control, instrument control, and data acquisition. |

Accelerate Application Development |

 IMAQ
Vision is designed to be easy-to-use, specifically built to meet the requirements
of imaging application developers under pressure to reduce costs and time
to market. Transparent memory management, logically named VIs, functions
and parameters make IMAQ Vision easy-to-use and learn.IMAQ Vision includes an extensive set of MMX-optimized functions for gray-scale, color and binary image display, image processing (statistics, filtering and geometric transforms), shape matching, blob analysis, gauging and measurement. End users, integrators and OEMs use IMAQ Vision to accelerate the development of industrial machine vision and scientific imaging applications. IMAQ Vision may be used in factory and laboratory automation operations that require extremely reliable, high-speed vision systems. |

|
Vision Application |
||||||
| Computer vision system are more reliable than manual inspection in high-speed, detailed, or repetitive manufacturing processes required to make semiconductors, electronic, medical and pharmaceutical products. Capture digital images of manufacturing processes in real time and extract critical information such as the location and orientation of parts or the presence or absence of defects. | ||||||
|
Performance Gains with Intel MMX |
||||||
| IMAQ Vision for Windows 95/98/2000 & NT takes advantage of Intel's MMX technology. MMX technology accelerates integer or fixed-point arithmetic functions that are used to process 8-bit images in image processing applications. For many IMAQ Vision functions, a Pentium Processor with MMX shows up to 400 percent performance gain over the same function run on a standard Pentium processor. Because MMX technology consists of general-purpose instructions, it enhances the performance and maintains complete compatibility with the Intel architecture. MMX technology is also fully compatible with existing operating systems and application software. | ||||||
|
Image Acquisition Designed to Work with DAQ |
||||||
| IMAQ software and hardware is designed to work closely with National Instruments DAQ (Data Acquisition) products. The IMAQ hardware has RTSI bus, which shares timing signal among boards for timing and synchronization to correlate images with transducer data. Use LabVIEW and LabWindows/CVI Advanced Analysis functions for measuring and analyzing waveforms, and IMAQ Vision to process synchronized images. Use IMAQ and DAQ hardware to guide the placements of components into circuit boards and to control microscope stages. | ||||||
|
Image Display Tools |
||||||
| Use image display primitives for fast image display. Use the interactive image display with region of interest (ROI), zoom and line profile tools. Plus, draw lines, rectangles, arcs circles, ellipses with selectable color. And, use display features to add cursors and line profiles, bitmaps and text to an image. | ||||||
|
Blob Analysis and Morphology |
||||||
Use blob analysis
functions to analyze connected pixels (blobs) in an image. Count, label
and measure cells and objects. Calculate the area, perimeter, orientation
and location and 50 other parameters with blob analysis functions. Plus,
to make counting easier, change the shape of blobs with morphology functions
(erode, dilate, fill holes, convex, reject object on border ...), and remove
and filter blobs of certain size with spatial filters.
|
||||||
|
Measurement and Gauging |
||||||
| Use gauging, caliper,
measurement functions to automatically locate edges and to measure distances
and angles between edges of an object. Measure from point to point using
the line profile and interactive display window. Specify reference markers
and calculate measurements between markers. In your production application,
measure critical distances and compare to a tolerance; then reject the flawed
products. Find the position, angle, and sharpness of an edge, and calculate
edge distance measurements with sub-pixel accuracy.
|
||||||
|
Shape Matching and Searching |
||||||
| Use the shape matching and searching tool for alignment, measurement and inspection applications. Train on a binary object, and then search for the object. The search tool finds objects of the same shape even if their size and orientation are different. Specify search parameters and constraints to limit the search. The search functions use a smart search strategy to quickly find an object. | ||||||
|
Image Processing |
||||||
| Use IMAQ Vision image processing functions to filter, manipulate, smooth and quantify images. Arithmetic operations include add, subtract, multiply and divide. Plus, there are logical operations - NOT, AND, OR, XOR and compare. Image statistics functions include histogram, histogram equalization, min and max values. Filtering functions include threshold, autothreshold, low-pass filter (Gaussian), median filter, edge detection, and custom filter of any kernel size. Use complex functions such as 2D FFT and frequency domain filtering to further analyze your images. | ||||||

This
software package is a LabVIEW Vi's library (llb file) for developing
applications that permits to control, and acquire images from
DV camcorders under LabVIEW & IMAQ Vision environments.
