Assembly: Cognex.VisionPro3D (in Cognex.VisionPro3D.dll) Version: 65.1.0.0
Property Value
Type: DoubleA range image pixel is "used" to calculate the volume if:
- it is inside the 2D input [P:Cognex::VisionPro3D::Cog3DRangeImageVolumeCalculatorTool::Region] of the tool.
- it is marked as "care" in the optional [P:Cognex::VisionPro3D::Cog3DRangeImageVolumeCalculator::InputImageMask] provided as part of the [P:Cognex::VisionPro3D::Cog3DRangeImageVolumeCalculatorTool::RunParams].
- it is marked as a "visible pixel" in the visible pixel mask of the [P:Cognex::VisionPro3D::Cog3DRangeImageVolumeCalculatorTool::InputImage]. The visible pixel mask can be accessed by calling GetMaskData on the range image.
- its height (relative to the base plane) is greater than or equal to the [P:Cognex::VisionPro3D::Cog3DRangeImageVolumeCalculator::MinimumHeightThreshold].
Pixels that meet these conditions contribute to the volume computation and are marked as "used" in the PixelCountsDiagImage.
Note that the height of an individual range image pixel is defined as the signed distance from the center of the range image pixel to the nearest point on the base plane (measured in selected space 3D units).
Note, however, that the volume is calculated by summing the contribution of the range image pixels within the [P:Cognex::VisionPro3D::Cog3DRangeImageVolumeCalculatorTool::Region] projected along the pixel coordinate z axis until they intersect the base plane.
