AW00011916000 Image Acquisition Control
Basler scout GigE 145
Use Case 1 - Acquisition and Frame Start Triggers Both Off (Free Run)
Use case one is illustrated on page 146.
In this use case, the Acquisition Mode parameter is set to continuous. The Trigger Mode parameter
for the acquisition start trigger and the Trigger Mode parameter for the frame start trigger are both
set to off. The camera will generate all required acquisition start and frame start trigger signals
internally. When the camera is set this way, it will constantly acquire images without any need for
triggering by the user. This use case is commonly referred to as "free run".
The rate at which the camera will acquire images will be determined by the camera’s Acquisition
Frame Rate Abs parameter unless the current camera settings result in a lower frame rate. If the
Acquisition Frame Rate Abs parameter is disabled, the camera will acquire frames at the maximum
allowed frame rate.
Cameras are used in free run for many applications. One example is for aerial photography. A
camera set for free run is used to capture a continuous series of images as an aircraft overflies an
area. The images can then be used for a variety of purposes including vegetation coverage
estimates, archaeological site identification, etc.
For more information about the Acquisition Frame Rate Abs parameter, see Section 9.5.1.1 on
page 119 and for information about setting the parameter, see Section 9.5.1.3 on page 121.
