Auto Function Profile (dart E)#

Auto Function Profile 相机功能定义了相机进行自动调整时如何平衡增益和曝光时间。

该功能的使用#

设置自动功能配置文件#

要设置自动功能配置文件：

  1. 将 Gain Auto 自动功能和 Exposure Auto 自动功能设置为 Continuous。
  2. 设置 AutoFunctionProfile 参数设置为以下值：
    • AntiFlicker50Hz：为 50 Hz 电源线频率启用减少闪烁（适用于欧洲等地区）。
    • AntiFlicker60Hz：为 60 Hz 电源线频率启用减少闪烁（适用于北美等地区）。
    • AntiFlickerAuto：通过自动电源线频率检测启用减少闪烁。
    • MinimizeExposureTime：在自动调节过程中保持尽可能短的曝光时间。
    • MinimizeGain（默认）：在自动调节过程中保持尽可能低的增益。

示例代码#

// Set the auto function profile to Minimize Gain
camera.AutoFunctionProfile.SetValue(AutoFunctionProfile_MinimizeGain);
// Set the auto function profile to Minimize Exposure Time
camera.AutoFunctionProfile.SetValue(AutoFunctionProfile_MinimizeExposureTime);
// Enable Gain and Exposure Auto auto functions and set the operating mode to Continuous
camera.GainAuto.SetValue(GainAuto_Continuous);
camera.ExposureAuto.SetValue(ExposureAuto_Continuous);

INodeMap& nodemap = camera.GetNodeMap();
// Set the auto function profile to Minimize Gain
CEnumParameter(nodemap, "AutoFunctionProfile").SetValue("MinimizeGain");
// Set the auto function profile to Minimize Exposure Time
CEnumParameter(nodemap, "AutoFunctionProfile").SetValue("MinimizeExposureTime");
// Enable Gain and Exposure Auto auto functions and set the operating mode to Continuous
CEnumParameter(nodemap, "GainAuto").SetValue("Continuous");
CEnumParameter(nodemap, "ExposureAuto").SetValue("Continuous");

// Set the auto function profile to Minimize Gain
camera.Parameters[PLCamera.AutoFunctionProfile].SetValue(PLCamera.AutoFunctionProfile.MinimizeGain);
// Set the auto function profile to Minimize Exposure Time
camera.Parameters[PLCamera.AutoFunctionProfile].SetValue(PLCamera.AutoFunctionProfile.MinimizeExposureTime);
// Enable Gain and Exposure Auto auto functions and set the operating mode to Continuous
camera.Parameters[PLCamera.GainAuto].SetValue(PLCamera.GainAuto.Continuous);
camera.Parameters[PLCamera.ExposureAuto].SetValue(PLCamera.ExposureAuto.Continuous);

/* 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 */
/* Set the auto function profile to Minimize Gain */
errRes = PylonDeviceFeatureFromString(hdev, "AutoFunctionProfile", "MinimizeGain");
CHECK(errRes);
/* Set the auto function profile to Minimize Exposure Time */
errRes = PylonDeviceFeatureFromString(hdev, "AutoFunctionProfile", "MinimizeExposureTime");
CHECK(errRes);
/* Enable Gain and Exposure Auto auto functions and set the operating mode to Continuous */
errRes = PylonDeviceFeatureFromString(hdev, "GainAuto", "Continuous");
CHECK(errRes);
errRes = PylonDeviceFeatureFromString(hdev, "ExposureAuto", "Continuous");
CHECK(errRes);

# Set the auto function profile to Minimize Gain
camera.AutoFunctionProfile.Value = "MinimizeGain"
# Set the auto function profile to Minimize Exposure Time
camera.AutoFunctionProfile.Value = "MinimizeExposureTime"
# Enable Gain and Exposure Auto auto functions and set the operating mode to Continuous
camera.GainAuto.Value = "Continuous"
camera.ExposureAuto.Value = "Continuous"

You can also use the pylon Viewer to easily set the parameters.
