Problem

Building a 3D shape database requires scanning many objects. Off-the-shelf scanning is fine for one model, but at database scale it costs human hours: every object shape requires re-tuning algorithm parameters, and every mis-registration eats into the ~5 min/object budget. The need is a robust pipeline that adapts — per-object parameter tuning has to disappear.

Pipeline

The system fuses three algorithmic stages tuned to handle scale, reflectance, and pose variation without manual intervention.

Frame-to-frame registration aligns sequential scans on both geometry and texture; an outlier removal stage strips away background noise; finally a global registration pass aligns the multiple platform poses into a coherent model.
