Technologies > Photogrammetry > Overview

Photogrammetry is an extremely versatile non-contactive measurement technique in which one uses multiple 2-D images of a object of interest to extract knowledge of where points/targets on that object are in 3-D space. The 2-D images are taken at a variety of locations/orientations surrounding (when possible) the object of interest. Mevicon Inc. personnel have significant experience in applying photogrammetry to a variety of applications.

Example high spatial and height resolution measurements of 0.5 m diameter thin film shells using projected light photogrammetry used by Mevicon

In addition to the development of photogrammetric technologies for characterization single surface shells in detail, Mevicon Inc. personnel use it regularly as part of their ongoing research efforts in the area of thin film membrane structures. Current test support equipment includes 6 MegaPixel SLR digital imagers, supporting test equipment, and Photomodeler-Pro photogrammetry post processing software. Placed, projected, and physical feature recognition methods are used to locate and centroid tracked targets.
