Image Acquisition Toolbox

Overview

The Image Acquisition Toolbox is a collection of functions that extend the capability of the MATLAB® numeric computing environment.

The Image Acquisition Toolbox implements an object-oriented approach to image acquisition. Using toolbox functions, you create an object that represents the connection between MATLAB and specific image acquisition devices. Using properties of the object you can control various aspects of the acquisition process, such as the amount of video data you want to capture. Connecting to Hardware, describes how to create objects.

Once you establish a connection to a device, you can acquire image data by executing a trigger. In the toolbox, all image acquisition is initiated by a trigger. The toolbox supports several types of triggers that let you control when an acquisition takes place. For example, using hardware triggers you can synchronize an acquisition with an external device. Acquiring Image Data describes how to trigger the acquisition of image data.

To work with the data you acquire, you must bring it into the MATLAB workspace. When the frames are acquired, the toolbox stores them in a memory buffer. The toolbox provides several ways to bring one or more frames of data into the workspace where you can manipulate it as you would any other multidimensional numeric array. Working with Acquired Image Data, describes this process.

Finally, you can enhance your image acquisition application by using event callbacks. The toolbox has defined certain occurrences, such as the triggering of an acquisition, as events. You can associate the execution of a particular function with a particular event. Using Events and Callbacks, describes this process.
