Photogrammetry
Definition: The science and art of determining the position and shape of
objects from two or more images acquired from different perspectives.
Our photogrammetry team consists of academically trained personnel with over
40 years of experience applying the science of image based measurement to derive
static and dynamic engineering data from ground, sea, air, and space-based cameras,
particularly in imagery that was not originally intended for study.
Examples of Photogrammetry Applications: (Example 1) Determination of depth in damaged surface.
(Example 2) 3-D photogrammetry of surface ablation. (Example 3) Launch vehicle stack alignment verification.
(Example 4) Dynamic motion analysis supports refinement of structural load models. Credit: NASA.
We utilize photogrammetric techniques from both aerial mapping (stereo analysis) and
close range industrial measurement (convergent analysis) to design custom, non-traditional
approaches for each measurement task. Our staff specializes in the measurement of natural
features in situations where many of the commercial measurement systems fail.
