Image Acquisition ControlBasler pioneer 117You can also use the Basler pylon Viewer application to easily set the parameters.For more information about the pylon Viewer, see Section 2.2 on page 20 and Section 2.4 onpage 40.10.2.2 Acquiring a Single Image by ApplyingOne Software TriggerYou can set the camera to react to a single software trigger and then issue a software trigger tobegin image acquisition. To do so, follow this sequence:1. Access the camera’s API and set the exposure time parameter for your desired exposure time.2. Set the value of the camera’s Acquisition Mode parameter to Single Frame.3. Execute an Acquisition Start command. This prepares the camera to react to a softwaretrigger.4. When you are ready to begin an image acquisition, execute a Trigger Software command.5. Image acquisition will start and exposure will continue for the length of time you specified instep 1.6. At the end of the specified exposure time, readout and transmission of the acquired image willtake place.7. At this point, the camera would ignore any additional software triggers. To acquire anotherimage, you must:a. Repeat step 3 to prepare the camera to react to a software trigger.b. Repeat step 4 to issue a software trigger.If you use the single image acquisition process repeatedly, you must not begin acquisition of a newimage until transmission of the previously acquired image is complete.You can set the exposure time and the Acquisition Mode parameter values from within yourapplication software by using the pylon API. You can also execute the Acquisition Start and TriggerSoftware commands. The following code snippets illustrate using the API to set the parametervalues and execute the commands:Camera.ExposureTimeRaw.SetValue( 200 );Camera.AcquisitionMode.SetValue( AcquisitionMode_SingleFrame );// prepare for image captureCamera.AcquisitionStart.Execute( );Camera.TriggerSoftware.Execute( );// retrieve the captured imageFor detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guideand API Reference.You can also use the Basler pylon Viewer application to easily set the parameters.For more information about the pylon Viewer, see Section 2.2 on page 20 and Section 2.4 onpage 40.For more information about the camera’s exposure time parameter, see Section 10.4 on page 127.
