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：

• 在 ace 2, boost, dart M/R, and racer 2 cameras, execute the BslCenterX command.
  The camera adjusts the OffsetX parameter value to center the 图像 ROI horizontally. This is a one-time operation. When you change the width of the 图像 ROI, you must execute the command again.
• 在 other cameras, set the CenterX parameter to true.
  The camera adjusts the OffsetX parameter value to center the 图像 ROI horizontally. When you change the width of the 图像 ROI, the OffsetX parameter value automatically adapts. The OffsetX parameter becomes read-only.

使用 Center Y#

要将图像垂直居中：

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

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

• 在 other cameras, set the CenterY parameter to true.
  The camera adjusts the OffsetY parameter value to center the 图像 ROI vertically. When you change the height of the 图像 ROI, the OffsetY parameter value automatically adapts. The OffsetY parameter becomes read-only.

CHECK(errRes);

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

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

CHECK(errRes);
errRes = PylonDeviceSetBooleanFeature(hdev, "CenterY", 1);
CHECK(errRes);

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