THE PROBLEM
Two scans need a common reference before differences in shape or coverage can be interpreted.
THE WORKFLOW
PCA initialization and trimmed ICP estimate the rigid motion. Bidirectional distances flag added or absent geometry, with a 3D viewer and PLY/CSV exports.

Source: local pipeline execution on the identified inputs. CPU; no GPU. HTTP timings refer to the interface samples; for reconstruction they measure loading recorded geometry, not a new reconstruction. These are not customer outcomes or a guarantee on other data.
A pilot for scan processing, alignment, geometric analysis and reviewed change detection.
What we would define first
Units, sensor precision, common coverage, density, tolerances and independent acceptance measurements.
Demonstration limits
Procedural machinery assembly with three transforms and known changes. No real scanner was used. Distances alone cannot distinguish removal from occlusion. The result is not certified metrology.
