Installation and Configuration Notes The Image Processing Toolbox Software Required to Use the Image Acquisition Toolbox Software |
The Image Acquisition Toolbox software is a collection of functions that extend the capability of the MATLAB® numeric computing environment. The toolbox supports a wide range of image acquisition operations, including:
Acquiring images through many types of image acquisition devices, from professional grade frame grabbers to USB-based webcams
Viewing a preview of the live video stream
Triggering acquisitions (includes external hardware triggers)
Configuring callback functions that execute when certain events occur
Bringing the image data into the MATLAB workspace
Many of the toolbox functions are MATLAB files. You can view the MATLAB code for these functions using this statement:
type function_name
You can extend Image Acquisition Toolbox capabilities by writing your own MATLAB files, or by using the toolbox in combination with other toolboxes, such as the Image Processing Toolbox™ software and the Data Acquisition Toolbox™ software.
The Image Acquisition Toolbox software also includes a Simulink® block, called From Video Device, that you can use to bring live video data into a model.
To determine if the Image Acquisition Toolbox software is installed on your system, type this command at the MATLAB prompt:
ver
When you enter this command, MATLAB displays information about the version of MATLAB you are running, including a list of all toolboxes installed on your system and their version numbers.
For information about installing the toolbox, see the MATLAB Installation Guide.
For the most up-to-date information about system requirements, see the system requirements page, available in the products area at the MathWorks Web site (www.mathworks.com).
The Image Acquisition Toolbox product, including the Image Acquisition Tool, now requires you to have a license for the Image Processing Toolbox product starting in R2008b.
If you already have the Image Processing Toolbox product, you do not need to do anything.
If you do not have the Image Processing Toolbox product, the Image Acquisition Toolbox software R2008a and earlier will continue to work. If you want to use R2008b or future releases, and you have a current active license for the Image Acquisition Toolbox software, you can download the Image Processing Toolbox product for free. New customers will need to purchase both products to use the Image Acquisition Toolbox product.
If you have any questions, please contact MathWorks customer service.
MathWorks provides several products that are relevant to the kinds of tasks you can perform with the Image Acquisition Toolbox software and that extend the capabilities of MATLAB. For information about these related products, see www.mathworks.com/products/imaq/related.html.
The list of hardware that the Image Acquisition Toolbox software supports can change in each release, since hardware support is frequently added. The MathWorks Web site is the best place to check for the most up to date listing.
To see the full list of hardware that the toolbox supports, visit the Image Acquisition Toolbox product page at the MathWorks Web site www.mathworks.com/products/imaq and click the Supported Hardware link.
Demos are available that cover many areas of the Image Acquisition Toolbox functionality.
To view the demos, open the product documentation using the doc command or the Help icon in the MATLAB toolbar. Then under Image Acquisition Toolbox in the navigation pane, select Demos.
