Creates a point group by extracting sphere centers from a point cloud generated by a raster-format scanner (Sur- phaser scanner or FARO Photon scanner, for example).
Input Arguments
0 |
Collection Object Name |
Cloud Name |
The name of the point cloud in which to search for spheres. |
1 |
Double |
Desired Diameter |
The nominal diameter of the spheres. |
2 |
Double |
Extraction Tolerance |
The allowable tolerance on the desired diam- eter. Spheres exceeding this tolerance are not extracted. |
3 |
Integer |
Minimum Point Count |
The minimum number of points required for the sphere fit. If less points are detected, the sphere is not extracted. |
4 |
Collection Object Name |
Group Name for Points |
The group into which to place the extracted sphere centers. |
5 |
Boolean |
Perform Final Fit |
True performs the ASTM fit algorithm |
6 |
Double |
Final Fit Cone Angle |
Cone angle to apply |
Return Arguments
5 |
Integer |
Number of Points Extracted |
The number of center points extracted from the cloud. |
Returned Status
SUCCESS |
The points were extracted successfully. |
FAILURE |
The source cloud was not found. |
Remarks
When the Final Fit Boolean (A5) is set to True a more advance sphere fit is used. This method employs the standard sphere extraction method defined in ASME E3125-17. This method uses the instrument shot line to improve outlier rejection and further refine the location of the sphere center point.
