This filter is intended for stopping acquisition in a Flir camera device using Spinnaker SDK. It is only needed when implementing explicit stopping and starting of the image acquisition during a program lifetime.

This filter will usually be executed when image acquisition in a camera is already active (after filters like Spinnaker_GrabImage or Spinnaker_StartAcquisition has been executed). After its execution the image acquisition in a camera and on the application level will be stopped and all image data remaining in the input queue will be discarded. Image acquisition can be reestablished later by executing the Spinnaker_GrabImage, Spinnaker_GrabImage_WithTimeout or Spinnaker_StartAcquisition filters (pixel format and image input queue size parameters will be configured again by those filters).

This filter has no effect when invoked while the camera is not in the image acquisition state.

Camera driver software

This filter is intended to cooperate with camera using its vendor Spinnaker SDK. To be able to connect to camera it is required to install Spinnaker SDK software with camera dedicated drivers. Currently Aurora Vision Studio uses Spinnaker version v2.7.0.128.

Spinnaker SDK can be downloaded from the following website: https://www.flir.com/support/browse/camera-cores--components/machine-vision-cameras/sdks (registration may be required).

During installation you should select "Application Development". Visual Studio Version should be also changed to "Visual Studio 2015".

Camera identification

When there is only one camera connected to computer, inDeviceSerialNumber field can be set to Auto. In this situation first available camera will be found and connected.

inDeviceSerialNumber can be used to pick one of multiple cameras connected to computer. Set this field to device serial number (for example "1234567", should be available on device casing as "s/n: 1234567").

This filter is available on Advanced Complexity Level.

• Spinnaker_GrabImage – Captures images from a Flir camera using Spinnaker interface.

• Spinnaker_GrabImage_WithTimeout – Captures images from a Flir camera using Spinnaker interface; returns Nil if no frame comes in the specified time.

• Spinnaker_StartAcquisition – Starts image acquisition.
