Pixel Correction Beyond#

Pixel Correction Beyond 相机功能可动态校正图像中的坏点。

它会校正灰度值显著高于或低于相邻像素的像素。内部阈值决定了何时对像素进行校正。

“动态”意味着坏点校正是针对每幅采集到的图像单独计算的。

该功能的使用#

启用 Pixel Correction Beyond#

要启用 Pixel Correction Beyond：

设置 BslPixelCorrectionBeyondEnable acquisition mode true.
设置 BslPixelCorrectionBeyond 参数设为 0.0 到 1.0 之间的值。
这用于调整应用的动态坏点校正量。较高的值意味着图像中可见的坏点更少。但是，过高的值可能会导致图像信息丢失。

示例代码#

C++ (Native)C++ (Generic)C#C (Generic)Python

// Enable dynamic user defect pixel correction
camera.BslPixelCorrectionBeyondEnable.SetValue(true);
// Adjust the amount of defect pixel correction to be applied
camera.BslPixelCorrectionBeyond.SetValue(0.5);

INodeMap& nodemap = camera.GetNodeMap();
// Enable dynamic user defect pixel correction
CBooleanParameter(nodemap, "BslPixelCorrectionBeyondEnable").SetValue(true);
// Adjust the amount of defect pixel correction to be applied
CFloatParameter(nodemap, "BslPixelCorrectionBeyond").SetValue(0.5);

// Enable dynamic user defect pixel correction
camera.Parameters[PLCamera.BslPixelCorrectionBeyondEnable].SetValue(true);
// Adjust the amount of defect pixel correction to be applied
camera.Parameters[PLCamera.BslPixelCorrectionBeyond].SetValue(0.5);

/* 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 */
/* Enable dynamic user defect pixel correction */
errRes = PylonDeviceSetBooleanFeature(hdev, "BslPixelCorrectionBeyondEnable", 1);
CHECK(errRes);
/* Adjust the amount of defect pixel correction to be applied */
errRes = PylonDeviceSetFloatFeature(hdev, "BslPixelCorrectionBeyond", 0.5);
CHECK(errRes);

# Enable dynamic user defect pixel correction
camera.BslPixelCorrectionBeyondEnable.Value = True
# Adjust the amount of defect pixel correction to be applied
camera.BslPixelCorrectionBeyond.Value = 0.5
