We are specialists in providing photogrammetry services, whether it’s a large site or small highly detailed artifact, here at WGP Digital we have the knowledge and experience to provide effective solutions.
Using photogrammetry for surveying, 3d visualisations and 3d modelling is a highly effective solution, the use of drones/UAVs has further enhanced the photogrammetry process and deliverables.
“Photogrammetry is the art and science of extracting 3D data from photographs. The process involves taking overlapping photographs of an object, structure, or space, and converting them into 2D or 3D digital models.”
- Topographic surveys using a drone/UAV – especially for large areas, quarries etc. Where ‘feet on the ground’ surveys are too time consuming or difficult to reach.
- 3d models of artifacts – high resolution models of artifacts, accurate and realistic. See my case study on the Minerva Temple where this method was put to great use.
- 3d models of buildings – for internal or external uses, ground imagery can be combined with a drone/UAV to produce a point cloud/3d mesh.
- Rectified photography – again using ground and drone imagery produce high resolution rectified photographs, read more…
- Visualisations – for photorealistic visualisation schemes.
Historic England have produced a very informative 128 page guidance document, this explains all the different aspects and methods used in photogrammetry:
Millimetre accuracy is achieveable for small models or buildings – but dependant on comprehensive control or grid, however large schemes, sites etc the accuracy will decrease to centimetres.
In most cases it can be a more cost effective solution than laser scanning or boots on the ground survey. Worth discussing the project objectives to determine the most efficient solution.
