• Select at least 3 pairs of points with the same name in basic point cloud and registered point cloud, The
order of same name point must be consistent.
• Adjust the registration parameter (ICP), when registration RMS of error meets precision requirements,
click convert to complete registration. The meanings of ICP parameter are as follow:
1. Grid size: Point cloud tile grid size.
2. Number of iterations: The number of iterations of the ICP algorithm, generally 20.
3. Distance threshold: the maximum distance between points with the same name. If the searched
matching point is greater than the threshold, it will not participate in the calculation.
4. Iterative distance: the difference between the distances calculated before and after, if it is less than
this value, exit the iteration.
5. RMS is the root mean square error related to registration.
