3D photogrammetry is the process of reproducing a physical item in order to make an accurate 3D model. It can be used to capture everything from people and historical artefacts to aircraft, buildings and even larger structures.
"It's a very good way of making an object tangible and immersive, so you can look around it and see the texture of it," says John Maurice, European Product Marketing Manager at Canon Europe. "You can also do this in a CG render, but it's not the same because you never get all the nuances that photogrammetry captures."
The applications of digital photogrammetry and 3D modelling are endless, with the technique employed as a solution in manufacturing, engineering, design, entertainment and healthcare. "Creating 3D models of somebody can help with a diagnosis and the monitoring of treatment," explains John. "And if you work in industry, being able to make a 3D model cuts down on the expensive prototyping stage."
