Camera Fundamentals and Parameters in Photogrammetry
Photogrammetry is the science of using photographs to obtain measurements and models of real-world objects and scenes. Photogrammetric techniques involve using known information to help solve other, previously unknown information. Several critical pieces of known information concern the camera used to capture the photographs, and defining those pieces in mathematical terms known as camera parameters. […]
PhotoModeler’s Dense Surface Modeling Accuracy Study
We have completed an extensive accuracy study of PhotoModeler’s 3d scanning capability called Dense Surface Modeling (DSM). The full accuracy study article can be found here: Quantifying the accuracy of dense surface modeling within PhotoModeler Scanner. The article shows that PhotoModeler Scanner can match (if not exceed) the accuracy of a laser scanner. Using […]
