Detailed Description

Functions to configure the AQS12 Segmentor object.

Enumeration Type Documentation

◆ CVMAQS12SegmentationMethod

enum CVMAQS12SegmentationMethod

Contains the possible segmentation methods for the faces of AQS12 piece.

Enumerator

CVMSM_KmeansClustering

The faces of the AQS12 piece are clustered by the kmeans alogrithm.

This method can be applied for range maps or dense point clouds, where the base plane of the AQS12 is parallel to the xy plane. Pixels are clustered to 8 groups (top, base plane and 4 faces) using the kmeans.

CVMSM_PointCloudNormalDeviationClustering

The faces of the AQS12 piece are clustered by a condition region growing clustering algorithm on point clouds.

This method can be applied with dense or sparse point clouds. For the region growing clustering the AQS12 points are grouped by similar normals. In order to configure the clustering and necessary pre-processing steps, use function CVMAQS12CreateSegmentorForPointCloud.

◆ CVMAQS12SEGMENTOR3DFilterFeature

enum CVMAQS12SEGMENTOR3DFilterFeature

Contains possible features for point cloud filtering (pre- processing step for the segmentation).

The feature is calculated using a given number of neighbor points. The filtering can be configured with function CVMAQS12SegmentorPointCloudSetPreprocessingFilterGeometricFeature.

Enumerator
CVMAQS12_None	No feature is calculated.
CVMAQS12_Planarity	Planarity is calculated.
CVMAQS12_Variation	Variation is calculated.
CVMAQS12_Sphericity	Sphericity is caculated.

◆ CVMAQS12CreateSegmentorForDensePointCloud()

cvbres_t CVMAQS12CreateSegmentorForDensePointCloud	(	CVMAQS12SegmentationMethod	SegmentationMethod,
		CVMAQS12SEGMENTOR3D &	Segmentor
	)

Creates a default AQS12 segmentor for dense point clouds.

Attention

The following constraints for the point cloud have to be met:

The point cloud must be dense.
The AQS12 may not be tilted. The xy plane must be parallel to the base plane of the AQS12.
Disturbing background must be eliminated by setting these points to non-confident. You can create a calibrated dense point cloud with function CVC3DCreateCalibratedPointCloudFromRangeMap. Before creating the cloud, set the range map ignore value with function CVC3DCalibratorSetRangeMapIgnoreValue. All pixels with this value will be interpreted as non-confident.

Note: If this function returns successfully you need to release the returned Segmentor via ReleaseObject if not needed anymore.

Parameters

[in]	SegmentationMethod	Segmentation method to be applied (so far only CVMSM_KmeansClustering is supported).
[out]	Segmentor	Variable to receive the resulting segmentor object.

Returns

CVC_ERROR(CVC_E_OK) on success
CVC_ERROR(CVC_E_PARAMETER) segmentation method not supported
CVC_ERROR(CVC_E_MEMORY) if not enough memory was available to create the Segmentor.
