Photogrammetry: The science and art of determining the position and shape of objects from two or more images (film, video or digital 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.
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.
Our photogrammetry expertise includes:
