TOOLS & TECHNOLOGYadvanced
Definition
A technique for creating accurate 3D models from overlapping photographs. Software analyses multiple images taken from different angles to reconstruct surfaces and geometry. Architects use photogrammetry for surveying existing buildings, heritage documentation, and generating site models.
Example
After the 2019 fire at Notre-Dame de Paris, photogrammetric records made by art historian Andrew Tallon were used by restoration architects to reconstruct precise details of the destroyed spire.
