Center X and Center Y#

相机的 Center X and Center Y 功能使您可以水平和/或垂直地将图像 ROI 居中。

该功能的使用#

使用 Center X#

要将图像水平居中：

• On ace 2, boost, dart M/R, and racer 2 cameras, execute the BslCenterX command.
  The camera adjusts the OffsetX parameter value to center the image ROI horizontally. This is a one-time operation. When you change the width of the image ROI, you must execute the command again.
• 在其他相机上，将 CenterX 参数设置为 true。
  相机调整 OffsetX 参数值使 image ROI 水平居中。更改 image ROI 的 width 时，OffsetX 参数值会自动调整。OffsetX 参数变为只读。

使用 Center Y#

要将图像垂直居中：

• On ace 2, boost, and dart M/R cameras, execute the BslCenterY command.
  The camera adjusts the OffsetY parameter value to center the image ROI vertically. This is a one-time operation. When you change the height of the image ROI, you must execute the command again.

  Note: On racer 2 cameras, the BslCenterY command and the OffsetY parameter are not available.

• 在其他相机上，将 CenterY 参数设置为 true。
  相机调整 OffsetY 参数值使 image ROI 垂直居中。更改 image ROI 的 height 时，OffsetY 参数值会自动调整。OffsetY 参数变为只读。

示例代码#

ace 2, boost, dart M, and dart R Cameras#

// Center the image ROI
camera.BslCenterX.Execute();
camera.BslCenterY.Execute();

INodeMap& nodemap = camera.GetNodeMap();
// Center the image ROI
CCommandParameter(nodemap, "BslCenterX").Execute();
CCommandParameter(nodemap, "BslCenterY").Execute();

// Center the image ROI
camera.Parameters[PLCamera.BslCenterX].Execute();
camera.Parameters[PLCamera.BslCenterY].Execute();

/* 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 */
/* Center the image ROI */
errRes = PylonDeviceExecuteCommandFeature(hdev, "BslCenterX");
CHECK(errRes);
errRes = PylonDeviceExecuteCommandFeature(hdev, "BslCenterY");
CHECK(errRes);

# Center the image ROI
camera.BslCenterX.Execute()
camera.BslCenterY.Execute()

其他相机#

// Center the image
camera.CenterX.SetValue(true);
camera.CenterY.SetValue(true);

INodeMap& nodemap = camera.GetNodeMap();
// Center the image
CBooleanParameter(nodemap, "CenterX").SetValue(true);
CBooleanParameter(nodemap, "CenterY").SetValue(true);

// Center the image
camera.Parameters[PLCamera.CenterX].SetValue(true);
camera.Parameters[PLCamera.CenterY].SetValue(true);

/* 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 */
/* Center the image */
errRes = PylonDeviceSetBooleanFeature(hdev, "CenterX", 1);
CHECK(errRes);
errRes = PylonDeviceSetBooleanFeature(hdev, "CenterY", 1);
CHECK(errRes);

# Center the image
camera.CenterX.Value = True
camera.CenterY.Value = True
