What Is Registration in 3D Laser Scanning?

Registration is how individual laser scans are aligned into one accurate model — the step that determines survey-grade accuracy.

Aligning many scans into one

A building is captured from many scanner positions. Registration stitches those individual scans into a single coordinate system. The tighter the registration, the more accurate the final point cloud — typically 2–4 mm.

Why it matters

Good registration is what makes a scan trustworthy for BIM, fabrication, and coordination. Learn how accuracy works.
