Align Cloud to CAD

Aligns cloud to CAD surfaces and return the resultant transform, RMS, average and max errors.

 

Input Arguments

 

0

Collection Object Name

Cloud Name

The name of the cloud to align.

1

Collection Object Name Ref List

Surfaces

The name of the reference surface to be used in the alignment.

2

Double

Maximum Course CAD Mesh

Edge Length

The mesh edge length defines its resolution. Use a

larger number for a faster solution.

3

Boolean

Use Fine CAD Mesh (50% of Coarse)?

Use a fine mesh in the alignment process.

4

Boolean

Execute Alignment?

Choose whether to move instrument during the

alignment.

 

Return Arguments

 

5

Double

RMS Deviation

Resulting RMS deviation of the alignment.

6

Double

Average Deviation

Average deviation of the alignment.

7

Double

Maximum Absolute Deviation

Maximum deviation of the alignment.

8

Transform

Resultant Transform in Working Frame

The data transformation after alignment.

 

Returned Status

 

SUCCESS

The cloud was aligned successfully.

FAILURE

The cloud or surface could not be found.

 

Remarks

Mesh Edge length (A2) used to be a fixed 10mm but that made the conversion process take a lot time with large mod- els. Use the finest mesh for the best results but this will take longer to compute. Values <5mm will be automatically set to exactly 5mm.

With Execute Alignment disabled the opportunity exists to move other objects in the job (such as CAD surfaces) using the inverse of the resulting analytical transform.
