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 an instrument 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.

Requirements and hardware setup

  • MATLAB R2016a or later, Image Acquisition Toolbox, and GigE Vision hardware support package

Connect to camera Create a videoinput with the desired video format and get access to the camera device specific properties. When using the videoinput gige adaptor, the camera GenICam features and parameter values are represented as videoinput source properties.

v = videoinput('gige', 1, 'Mono8');
s = v.Source;
% Determine optimum streaming parameters as described in the
% "GigE Vision Quick Start Configuration Guide"
% s.PacketSize =
% s.PacketDelay =

Immediate acquisition By default, an immediate acquisition takes place when videoinput start function is executed, if a hardware triggering configuration is not explicitly specified.

For simplicity, this example performs an acquisition of a finite number of frames, and stores them in MATLAB base workspace.

% Set exposure time and mode
s.ExposureMode = 'Timed';
s.ExposureTimeAbs = 4000;
% The default videoinput trigger type is 'immediate', which is explicitly
% configured here for clarity.
triggerconfig(v, 'immediate');
% Specify number of frames to acquire
v.FramesPerTrigger = 30;
v.TriggerRepeat = 0;
% Start continuous buffered acquisition and wait for acquisition to complete
wait(v, 10);
% Transfer acquired frames and timestamps from acquisition input buffer
% into workspace
[data, ts] = getdata(v, v.FramesAvailable);

Display acquired frames and plot acquisition timestamps.

plot(ts, '.')
xlabel('Frame index');
ylabel('Timestamp (s)');

FrameStart trigger Most GigE Vision cameras support a FrameStart hardware trigger mode, which is used to configure the camera to acquire a frame for each rising edge (or falling edge) signal applied to a camera line input.
