Acquisition Mode

采集模式 允许用户选择选择单帧或连续图像采集。

    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 :单帧采集模式
  • AcquisitionMode_Continuous   :连续采集模式

代码示例

// 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

每次采集开始触发后要采集的帧数

camera.AcquisitionFrameCount.SetValue(1);
int64_t i = camera.AcquisitionFrameCount.GetValue();

 

Trigger Selector

触发类型选择

    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          单幅图像
  • TriggerSelector_AcquisitionStart   多幅画面
// 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

针对触发类型的触发模式选择。

    enum TriggerModeEnums
    {
        TriggerMode_Off,  //!<Sets the mode for the selected trigger to off
        TriggerMode_On   //!<Sets the mode for the selected trigger to on

    };

 代码如下

// Select the Frame Start trigger
camera.TriggerSelector.SetValue(TriggerSelector_FrameStart);
// Enable triggered image acquisition for the Frame Start trigger
camera.TriggerMode.SetValue(TriggerMode_On);

默认,每种触发类型的触发模式都被设为 OFF。也即意味着 “自由运行图像采集” 被打开。所有的 Basle 相机默认都是自由运行图像采集模式。

 

Free Run Image Acquisition

自由运行图像采集模式不需要用户触发。这个选项不在 Pylon Viewer ,需要编程设置。

设置方式:

  1. 设置采集模式为连续 AcquisitionMode_Continuous
  2. 选择一种触发类型,比如 FrameStart
  3. 设置触发模式为 OFF
  4. 重复上述步骤设置所有触发类型

 

Trigger Source

触发源可以选择硬件或软件。

    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_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_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

camera.TriggerSelector.SetValue(TriggerSelector_FrameStart);
// Set the trigger source to Line 1
camera.TriggerSource.SetValue(TriggerSource_Line1);

 

Trigger Activation

指定硬件触发时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

 

代码示例

// 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

用软件触发相机,设置:

  1. 设置触发类型,比如 FrameStart
  2. 设置触发模式为 ON
  3. 设置触发源为 Software
  4. 执行 TriggerSoftware 命令

代码示例

// 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();
