Photogrammetry is the science of taking measurements from photographs. A real-world object or scene is surveyed with a camera, and the resulting photographs are used to take a measurement, reverse engineer, or create an as-built drawing, as-built plan or a 3D model.
Photogrammetry is a highly adaptable technique for documenting the as-built status of a facility including 3D visualisation, and as-built plans and drawings, or for the generation of flattened GIS-referenced or dimensionally accurate orthoimages for building or land surveys.
At Offset we have a long and successful pedigree of close-range photogrammetry and image-based modelling. We use calibrated digital cameras to model and measure buildings, process plants, engineering structures, archaeological artefacts and heritage sites. We process the output using the photogrammetry software we have developed in-house, enabling us to create a broad set of project deliverables such as as-built plans, as-built drawings, 3D models, site measurements and point clouds.
We are experts in the use of photogrammetry or laser scanning for asset 3D data capture and we help our clients choose the best solution from both techniques.
