Trigger Software

相机的 Trigger Software 功能允许您通过执行软件命令来触发相机。

该功能的使用

通过执行软件命令来触发相机：

1. 将 TriggerSelector 参数设置为所需的 触发类型，例如 FrameStart。
2. 将 TriggerMode 参数设置为 On。
3. 将 TriggerSource 参数设置为 Software。
4. 执行 TriggerSoftware 命令。
   发送软件触发信号。该信号会触发选定的触发类型。

示例代码

C++ (Native)

// Select the Frame Start trigger
camera.TriggerSelector.SetValue(TriggerSelector_FrameStart);
// Enable triggered image acquisition for the Frame Start trigger
camera.TriggerMode.SetValue(TriggerMode_On);
// Set the trigger source for the Frame Start trigger to Software
camera.TriggerSource.SetValue(TriggerSource_Software);
// Generate a software trigger signal
camera.TriggerSoftware.Execute();

C++ (Generic)

INodeMap& nodemap = camera.GetNodeMap();
// Select the Frame Start trigger
CEnumParameter(nodemap, "TriggerSelector").SetValue("FrameStart");
// Enable triggered image acquisition for the Frame Start trigger
CEnumParameter(nodemap, "TriggerMode").SetValue("On");
// Set the trigger source for the Frame Start trigger to Software
CEnumParameter(nodemap, "TriggerSource").SetValue("Software");
// Generate a software trigger signal
CCommandParameter(nodemap, "TriggerSoftware").Execute();

C#

// Select the Frame Start trigger
camera.Parameters[PLCamera.TriggerSelector].SetValue(PLCamera.TriggerSelector.FrameStart);
// Enable triggered image acquisition for the Frame Start trigger
camera.Parameters[PLCamera.TriggerMode].SetValue(PLCamera.TriggerMode.On);
// Set the trigger source for the Frame Start trigger to Software
camera.Parameters[PLCamera.TriggerSource].SetValue(PLCamera.TriggerSource.Software);
// Generate a software trigger signal
camera.Parameters[PLCamera.TriggerSoftware].Execute();

C (Generic)

/* Macro to check for errors */
#define CHECK(errc) if (GENAPI_E_OK != errc) printErrorAndExit(errc)
GENAPIC_RESULT errRes = GENAPI_E_OK;  /* Return value of pylon methods */
/* Select the Frame Start trigger */
errRes = PylonDeviceFeatureFromString(hdev, "TriggerSelector", "FrameStart");
CHECK(errRes);
/* Enable triggered image acquisition for the Frame Start trigger */
errRes = PylonDeviceFeatureFromString(hdev, "TriggerMode", "On");
CHECK(errRes);
/* Set the trigger source for the Frame Start trigger to Software */
errRes = PylonDeviceFeatureFromString(hdev, "TriggerSource", "Software");
CHECK(errRes);
/* Generate a software trigger signal */
errRes = PylonDeviceExecuteCommandFeature(hdev, "TriggerSoftware");
CHECK(errRes);

您也可以使用 pylon Viewer 轻松设置参数。
