Acquisition Start, Stop, and Abort#

The Acquisition Start, Stop, and Abort commands allow you to control image acquisition.

Info

  • These commands aren't available via the pylon Viewer feature tree. Instead, AcquisitionStart and AcquisitionStop commands are generated automatically when you use the Single Shot, Continuous Shot, and Stop buttons in the toolbar of the pylon Viewer.
  • The pylon C++ API and the pylon .NET API provide camera classes that handle these commands automatically. Basler recommends using these classes.
    For more information, see the Grab (C++) and Grab (.NET) code samples in the pylon API Documentation.

Using the Feature#

Starting Image Acquisition#

To switch on image acquisition, execute the AcquisitionStart command.

After the command has been executed, the camera waits for trigger signals. Trigger signals can either be generated internally by the camera (free run) or applied externally (triggered image acquisition).

Info

To check whether the camera is currently waiting for a trigger signal, monitor the camera's Trigger Wait signals or use the Acquisition Status feature, if available.

Stopping Image Acquisition#

To switch off image acquisition, execute the AcquisitionStop command.

After the command has been executed, the following occurs:

  • If the camera is not currently acquiring a frame, image acquisition is switched off immediately.
  • If the camera is currently reading out image data, the readout process will be allowed to finish. Afterwards, image acquisition is switched off.
  • If the camera is currently exposing a frame:
    • On some camera models, executing an AcquisitionStop command aborts exposure. In this case, the camera stops exposing immediately and starts reading out image data. The readout process will be allowed to finish. Afterwards, image acquisition is switched off.
    • On some camera models, you can configure whether executing an AcquisitionStop command aborts exposure or not. To do so, set the BslAcquisitionStopMode parameter to AbortExposure or CompleteExposure.

Aborting Image Acquisition#

To abort image acquisition, execute the AcquisitionAbort command (if available).

After the command has been executed, the following occurs:

  • If the camera is not currently acquiring a frame, image acquisition is switched off immediately.
  • If the camera is currently exposing a frame, the camera stops exposing immediately. The readout process, if already started, is aborted. The current frame will be incomplete. Afterwards, image acquisition is switched off.
  • If the camera is currently reading out image data, the camera stops the readout process immediately. The current frame will be incomplete. Afterwards, image acquisition is switched off.
