Acquisition Mode
采集模式 允許用戶選擇選擇單幀或連續圖像采集。
enum AcquisitionModeEnums { AcquisitionMode_SingleFrame, //!<Sets the acquisition mode to single frame AcquisitionMode_MultiFrame, //!<Sets the acquisition mode to multi frame AcquisitionMode_Continuous //!<Sets the acquisition mode to continuous };
例如
- AcquisitionMode_SingleFrame ：單幀采集模式
- AcquisitionMode_Continuous ：連續采集模式
代碼示例
// Configure single frame acquisition on the camera camera.AcquisitionMode.SetValue(AcquisitionMode_SingleFrame); // Switch on image acquisition camera.AcquisitionStart.Execute(); // The camera waits for a trigger signal. // When a Frame Start trigger signal has been received, // the camera executes an Acquisition Stop command internally. // Configure continuous image acquisition on the camera camera.AcquisitionMode.SetValue(AcquisitionMode_Continuous); // Switch on image acquisition camera.AcquisitionStart.Execute(); // The camera waits for trigger signals. // (...) // Switch off image acquisition camera.AcquisitionStop.Execute();
AcquisitionFrameCount
每次采集開始觸發后要采集的幀數
camera.AcquisitionFrameCount.SetValue(1); int64_t i = camera.AcquisitionFrameCount.GetValue();
Trigger Selector
觸發類型選擇
enum TriggerSelectorEnums { TriggerSelector_AcquisitionStart, //!<Selects the acquisition start trigger for configuration TriggerSelector_AcquisitionEnd, //!<Selects the acquisition end trigger for configuration TriggerSelector_AcquisitionActive, //!<Selects the acquisition active trigger for configuration TriggerSelector_FrameStart, //!<Selects the frame start trigger for configuration TriggerSelector_FrameEnd, //!<Selects the frame end trigger for configuration TriggerSelector_FrameActive, //!<Selects the frame active trigger for configuration TriggerSelector_LineStart, //!<Selects the line start trigger for configuration TriggerSelector_ExposureStart, //!<Selects the exposure start trigger for configuration TriggerSelector_ExposureEnd, //!<Selects the exposure end trigger for configuration TriggerSelector_ExposureActive //!<Selects the exposure active trigger for configuration };
例如
- TriggerSelector_FrameStart 單幅圖像
- TriggerSelector_AcquisitionStart 多幅畫面
// Select and enable the Frame Start trigger camera.TriggerSelector.SetValue(TriggerSelector_FrameStart); camera.TriggerMode.SetValue(TriggerMode_On); // Select and enable the Acquisition Start trigger camera.TriggerSelector.SetValue(TriggerSelector_AcquisitionStart); camera.TriggerMode.SetValue(TriggerMode_On); // Set the number of images to be acquired per Acquisition Start trigger signal to 3 camera.AcquisitionFrameCount.SetValue(3);
Trigger Mode
針對觸發類型的觸發模式選擇。
enum TriggerModeEnums { TriggerMode_Off, //!<Sets the mode for the selected trigger to off TriggerMode_On //!<Sets the mode for the selected trigger to on };
代碼如下
// Select the Frame Start trigger camera.TriggerSelector.SetValue(TriggerSelector_FrameStart); // Enable triggered image acquisition for the Frame Start trigger camera.TriggerMode.SetValue(TriggerMode_On);
默認，每種觸發類型的觸發模式都被設為 OFF。也即意味着 “自由運行圖像采集” 被打開。所有的 Basle 相機默認都是自由運行圖像采集模式。
Free Run Image Acquisition
自由運行圖像采集模式不需要用戶觸發。這個選項不在 Pylon Viewer ，需要編程設置。
設置方式：
- 設置采集模式為連續 AcquisitionMode_Continuous
- 選擇一種觸發類型，比如 FrameStart
- 設置觸發模式為 OFF
- 重復上述步驟設置所有觸發類型
Trigger Source
觸發源可以選擇硬件或軟件。
enum TriggerSourceEnums { TriggerSource_Software, //!<Sets the software trigger as the signal source for the selected trigger TriggerSource_Line1, //!<Sets the signal source for the selected trigger to line 1 TriggerSource_Line2, //!<Sets the signal source for the selected trigger to line 2 TriggerSource_Line3, //!<Sets the signal source for the selected trigger to line 3 TriggerSource_Line4, //!<Sets the signal source for the selected trigger to line 4 TriggerSource_Line5, //!<Sets the signal source for the selected trigger to line 5 TriggerSource_Line6, //!<Sets the signal source for the selected trigger to line 6 TriggerSource_Line7, //!<Sets the signal source for the selected trigger to line 7 TriggerSource_Line8, //!<Sets the signal source for the selected trigger to line 8 TriggerSource_CC1, //!<Sets the signal source for the selected trigger to CC1 TriggerSource_CC2, //!<Sets the signal source for the selected trigger to CC2 TriggerSource_CC3, //!<Sets the signal source for the selected trigger to CC3 TriggerSource_CC4, //!<Sets the signal source for the selected trigger to CC4 TriggerSource_ShaftEncoderModuleOut, //!<Sets the signal source for the selected trigger to the shaft encoder module. TriggerSource_FrequencyConverter, //!<Sets the signal source for the selected trigger to the frequency converter module. TriggerSource_Timer1Start, //!<Sets the signal source for the selected trigger to timer 1 start TriggerSource_Timer1End, //!<Sets the signal source for the selected trigger to timer 1 end TriggerSource_Counter1Start, //!<Sets the signal source for the selected trigger to counter 1 start TriggerSource_Counter1End, //!<Sets the signal source for the selected trigger to counter 1 end TriggerSource_UserOutput1, //!<Sets the signal source for the selected trigger to user output 1 TriggerSource_UserOutput2, //!<Sets the signal source for the selected trigger to user output 2 TriggerSource_Action1, //!<Sets the signal source for the selected trigger to action command signal 1 TriggerSource_Action2, //!<Sets the signal source for the selected trigger to action command signal 2 TriggerSource_Action3, //!<Sets the signal source for the selected trigger to action command signal 3 TriggerSource_Action4, //!<Sets the signal source for the selected trigger to action command signal 4 TriggerSource_VInput1, //!<Sets the signal source for the selected trigger to Virtual Input 1 TriggerSource_VInput2, //!<Sets the signal source for the selected trigger to Virtual Input 2 TriggerSource_VInput3, //!<Sets the signal source for the selected trigger to Virtual Input 3 TriggerSource_VInput4, //!<Sets the signal source for the selected trigger to Virtual Input 4 TriggerSource_VInputDecActive //!<Sets the signal source for the selected trigger to Virtual Input Decoder Active };
例如
- TriggerSource_Software
- TriggerSource_Line1
代碼示例
// Select the Frame Start trigger camera.TriggerSelector.SetValue(TriggerSelector_FrameStart); // Set the trigger source to Line 1 camera.TriggerSource.SetValue(TriggerSource_Line1);
Trigger Activation
指定硬件觸發時是上升沿或下降沿有效。
enum TriggerActivationEnums { TriggerActivation_RisingEdge, //!<Sets the selected trigger to become active on the rising edge of the source signal TriggerActivation_FallingEdge, //!<Sets the selected trigger to become active on the falling edge of the source signal TriggerActivation_AnyEdge, //!<Sets the selected trigger to become active on the falling or rising edge of the source signal TriggerActivation_LevelHigh, //!<Sets the selected trigger to become active when the source signal is high TriggerActivation_LevelLow //!<Sets the selected trigger to become active when the source signal is low };
例如：
- TriggerActivation_RisingEdge ：上升沿有效
- TriggerActivation_FallingEdge ：下降沿有效
代碼示例
// Select the Frame Start trigger camera.TriggerSelector.SetValue(TriggerSelector_FrameStart); // Set the trigger activation mode to rising edge camera.TriggerActivation.SetValue(TriggerActivation_RisingEdge);
Trigger Software
用軟件觸發相機，設置：
- 設置觸發類型，比如 FrameStart
- 設置觸發模式為 ON
- 設置觸發源為 Software
- 執行 TriggerSoftware 命令
代碼示例
// 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();
