Function Documentation

distance_rms()

float distance_rms	(	cvb.PointCloud	model,
		cvb.PointCloud	scene
	)

Approximates the root mean square of distances between two point clouds.

Parameters

model : cvb.PointCloud First point cloud.

scene : cvb.PointCloud Second point cloud.

Returns

float The distance.

match_downsampled_point_clouds()

cvb.match_3d.MatchingResult match_downsampled_point_clouds	(	cvb.PointCloud	model,
		cvb.PointCloud	scene,
		cvb.match_3d.MatchingParameters	parameters
	)

This function matches two point clouds.

This function matches two point clouds by the iterative closest point algorithm (ICP), see: The algorithm follows Arun KS, Huang TS, Blostein SD(1987) Least - squares fitting of two 3D point sets. IEEE Transactions on Pattern Analysis and Machine Intelligence 9:698-700.

Parameters

model : cvb.PointCloud First point cloud.

scene : cvb.PointCloud Second point cloud.

parameters : cvb.match_3d.MatchingParameters Parameters that control the algorithm.

Returns

cvb.match_3d.MatchingResult Object containing all results.
