The COPCOPBF command allows you to perform a best fit alignment of the reference pointcloud with a second pointcloud.
Below is an example code snippet for a COPCOPBF alignment:
A1 =ALIGNMENT/START,RECALL:STARTUP,LIST=YES
COPCOPBF/REFINE,SHOWALLPARAMS=TOG1,
ROUGH ALIGNPAIR/
THEO/<x,y,z>,<i,j,k>,
MEAS/<x1,y1,z1>
REF,TOG2,TOG3,,
ALIGNMENT/END
TOG1 lets you show or hide the parameters used for the rough alignment. It can be set to YES or NO.
ROUGH ALIGNPAIR/
THEO/x,y,z,i,j,k,
MEAS/x1,y1,z1
These rough alignment pairs of points are defined and selected using the Graphic Display window. The values next to THEO/ represent the point for the reference COP. The values next to MEAS/ represent the corresponding point on the second COP. These pairs are used to determine a rough transformation between the reference COP and the second COP which allows the two pointclouds to come close to allow further refinements of the alignment.
TOG2 determines the reference COP used for aligning to the second COP.
TOG3 determines the second COP used for the alignment back to the reference COP.
