Member Function Documentation

Extract() [1/3]

eVision.Easy3D.E3DTransformMatrix eVision.Easy3D.EPrincipalAxisExtractor.Extract

(

eVision.Easy3D.EPointCloud

pc

)

Computes the E3DTransformMatrix for a given EPointCloud.

This will compute the PCA, then select the direction of each axis of the basis so that this basis is as close as possible as the reference transform.

Optionally returns the standard deviation along the 3 axis.

Parameters

pc	Input point cloud.

Extract() [2/3]

eVision.Easy3D.E3DTransformMatrix eVision.Easy3D.EPrincipalAxisExtractor.Extract	(	eVision.Easy3D.EPointCloud	pc,
		out eVision.Easy3D.E3DPoint	stdDev )

Computes the E3DTransformMatrix for a given EPointCloud.

This will compute the PCA, then select the direction of each axis of the basis so that this basis is as close as possible as the reference transform.

Optionally returns the standard deviation along the 3 axis.

Parameters

pc	Input point cloud.
stdDev	Variable to store the X, Y and Z components of the standard deviation.

Extract() [3/3]

eVision.Easy3D.E3DTransformMatrix eVision.Easy3D.EPrincipalAxisExtractor.Extract	(	eVision.Easy3D.EPointCloud	pc,
		out float	stdDevX,
		out float	stdDevY,
		out float	stdDevZ )

Computes the E3DTransformMatrix for a given EPointCloud.

This will compute the PCA, then select the direction of each axis of the basis so that this basis is as close as possible as the reference transform.

Optionally returns the standard deviation along the 3 axis.

Parameters

pc	Input point cloud.
stdDevX	Variable to store the X component of the standard deviation.
stdDevY	Variable to store the Y component of the standard deviation.
stdDevZ	Variable to store the Z component of the standard deviation.

Deprecated

Deprecated in version 24.6. Scheduled to be removed in version 27.6.
