Structure from Motion
The photogrammetric algorithm that reconstructs 3D geometry from a set of overlapping 2D photographs by tracking common feature points across images.
Point Cloud
A set of millions of data points in 3D space, each representing a measured location on a surface — the primary output of laser scanning and dense photogrammetry.
LiDAR
A remote sensing technology that measures distances by emitting laser pulses and recording the return time — producing accurate 3D point clouds of surfaces.
Terrestrial Laser Scanning
Ground-based 3D laser scanning where a scanner on a tripod captures a dense point cloud of its surroundings from a fixed position — the standard method for interior heritage documentation.
Scan Registration
The process of aligning multiple individual laser scans into a single unified point cloud by identifying common reference points or overlapping geometry between scans.
