The Problem

Laser trackers need line-of-sight. CMMs cannot scale. Manual methods drift. Large assemblies and field jobs break every traditional measurement tool.

The Solution

Three things only photogrammetry can do

Large Parts

Accurate 3D coordinates across 20+ meter volumes with no warm-up, no fixed mounting, no vibration sensitivity.

Reference Networks

A common coordinate backbone that ties DIC, 3D scans, and dimensional inspection into one traceable dataset.

Field Ready

One engineer, one case, no power or network required. Measurement that goes where the part lives.

Portable accuracy

“Documented accuracy per VDI/VDE 2634 Part 1. Traceable measurement on the airfield, wind farm, or factory floor.”

Deployed by Trilion engineers across aerospace, energy, and civil
