| Module: | Vision3DStandard | 
|---|
Aligns (rotation + translation) a point grid to match best the reference point grid using a global registration algorithm.
| Name | Type | Range | Description | |
|---|---|---|---|---|
![]()  | 
				inPoints | Point3DGrid | Data points to be aligned, may contain background clutter. | |
![]()  | 
				inReferencePoints | Point3DGrid | Reference points to align to, may contain background clutter. | |
![]()  | 
				inSampleCount | Integer | 1 - ![]()  | 
				Number of random samples used by the registration algorithm. Recommended values are from 200 to several thousands. | 
![]()  | 
				inOverlap | Real | 0.0 - 1.0 | Defines the estimated overlap between two input grids (0 = no overlap, 1.0 = every point in inPoints is also in inReferencePoints). | 
![]()  | 
				inDeltaCorrection | Real | 0.0 - ![]()  | 
				Defines the accuracy of the final alignment. With smaller delta the amount of allocated memory increases. | 
![]()  | 
				inTransformLimits3D | TransformLimits3D* | Limits the maximum rotation angles and translation along each axis, of the final transform. | |
![]()  | 
				inMaxTranslationDistance | Real* | 0.0 - ![]()  | 
				Limits the length of the translation vector of the final transform. | 
![]()  | 
				inSeed | Integer* | Seed for a random generator used by the algorithm. | |
![]()  | 
				outAlignedPoints | Point3DGrid | The aligned input points. | |
![]()  | 
				outAlignment | Matrix | The transform that aligns best the input points to the reference points. | |
![]()  | 
				outDelta | Real | Returns estimated value of the parameter delta. | |
Errors
This filter can throw an exception to report error. Read how to deal with errors in Error Handling.
List of possible exceptions:
| Error type | Description | 
|---|---|
| DomainError | Input point array is empty in AdjustPointGrids3DGlobal. | 
| DomainError | Parameter inDeltaCorrection in AdjustPointGrids3DGlobal has to be greater than 0.0. | 
Complexity Level
This filter is available on Advanced Complexity Level.
