Photogrammetry

Photogrammetry is the process of capturing high-resolution imagery and stitching them together to create an accurate 3D model of a particular area in the real world. Sophisticated software is used to stitch the collated imagery to create a realistic, geo-referenced 3D model.

Public Safety

Particularly useful for disaster response and management, quickly create up to date 3D maps of impacted areas to help assess damage and manage relief efforts.

Agriculture & Forestry

Drone photogrammetry is one of the most widely used methods for creating geographic databases in forestry and natural resource management.

Asset Integrity & Inspection

Streamlining your inspection process, aerial photogrammetry can follow pre-planned routes for systematic inspections and create detailed visuals of assets.

Surveying & Construction

Photogrammetry drones can accurately create visual 3D models that allow you to make precise measurements and topographic maps.

Energy & Renewables

Create fast and detailed visual inspections of assets using photogrammetry drones, this reduces risk to workers and reduces the cost of each inspection.

Oil & Gas

Ensure visual inspections are carried out efficiently using aerial photogrammetry, map out vast areas of potential drilling areas quickly and easily to name just a few potential applications.

Government Body

There are a variety of uses for governments including mapping motorways, housing development construction, environmental monitors, building inspections and more.

Research & Education

Enhance learning experience and research efficiency with photogrammetry drones, create 3D models of everything from seal colonies to volcanoes and glaciers

FAQs

The relative accuracy of a photogrammetric survey can be roughly estimated to be between one and three times the ground sampling distance (GSD)*. GSD is the distance between two pixels as measured on the ground, from the centre of each pixel. As an example, if your GSD is 10cm, 1 pixel in your photograph will represent 10cm of coverage on the ground. The lower the GSD, the clearer your imagery, therefore the more ‘accurate’ your results will be.

Photogrammetry uses visual images and 3D geometry to create models. Each point in space is identified on two or more photos and then a piece of software finds the geometric intersection and figures out where that point is located in 3D space and maps it.

Photogrammetry software uses geometric intersections and plots points from two or more images in 3D space. This is a technique that was used in the late 1400s by Leonardo da Vinci when he developed the principles of perspective and projective geometry.
