Overview
For low-cost analog color image acquisition, National Instruments
offers the PCI-1405, which acquires analog video input from
standard color or monochrome cameras. The NI PCI-1405 comes
with easy-to-use image acquisition driver software which can
acquire, save and display images. Unlike multimedia “frame
grabbers”, the PCI-1405 features increased image processing
throughput, such as partial image acquisition with programmable
region of interest.
Easy-to-Use Driver Software
National Instruments NI-IMAQ driver level software offers the most
comprehensive software interface for image acquisition. NI-IMAQ is
included with the PCI-1405 board, as will as NI Measurement &
Automation Explorer (MAX) for easy configuration of cameras.
Using NI-IMAQ, you can quickly and easily acquire, save, and display
images without low-level programming. You can program your
image acquisition application in LabVIEW, LabWindows/CVI, and
Measurement Studio. In addition, NI-IMAQ controls the PCI-1405
digital I/O line.
(region of interest) feature. You can configure the size of the acquired
image using MAX, or use the ROI tools in the NI-IMAQ driver
software to transfer only a subset of the image to PC memory for
processing. Partial image scanning results in fewer pixels to process.
For example, using partial image scanning, you can reduce a 640 by
480 image to a 400 by 400 image and increase your processing speed
by operating on 48 percent fewer pixels.
Hardware
PCI Interface
The PCI bus is the electrical interface for the PCI-1405. The
National Instruments custom MITE ASIC for interfacing to the PCI
bus offers the highest image acquisition performance available. The
MITE ASIC can transfer data at a maximum sustained rate of
100 MB/s in master mode to maximize the use of the available
PCI bandwidth.
Onboard Memory
The PCI-1405 has 16 MB of onboard memory, useful for temporary
storage of images being transferred to the PCI bus.
Performance Gains with
Partial Image Acquisition
The PCI-1405 includes features that improve overall image
acquisition and image processing speed. You can choose to acquire
only a portion of the image using the onboard programmable ROI
Trigger and Strobe
You can use the digital I/O line as an input to trigger image
acquisition or as an output to control solenoids, solid-state relays,
or strobes.
