Acquisition Using GigE Vision Hardware

Acquire images from GigE Vision^® cameras

Image Acquisition Toolbox™ includes a separate interface for use with GigE Vision compliant cameras. This interface is designed for GigE Vision cameras and supports more GigE-specific functionality.

You can continue to use the GigE Vision adaptor (gige) with the videoinput object, or you can use the gigecam object, which takes advantage of GigE properties and features and is more consistent with GigE Vision conventions for displaying properties and managing selector properties.

For more information about choosing the interface, see GigE Vision Acquisition: gigecam Object vs. videoinput Object.

Note: The functionality for all supported hardware is now available via the Support Package Installer. Starting with R2014a, each adaptor is available separately through the Support Package Installer, and you must install the appropriate support packages to use the toolbox with your hardware. For more information, see Image Acquisition Support Packages for Hardware Adaptors.

Hardware-Triggered Acquisition with a GigE Vision Camera

Image Acquisition Toolbox™ provides functionality for hardware-triggered acquisition from GigE Vision® cameras. This is useful in applications where camera acquisition needs to be synchronized with another device (such as a DAQ device or another camera) by means of an external triggering signal. Other applications include controlling the acquisition frame rate with an external signal, or acquiring a multiple-exposure image sequence for high dynamic range (HDR) imaging. This example shows how to use the videoinput gige interface to configure a camera acquisition to allow external triggering-signal control over the frame rate and over the exposure time.
