Photogrammetry

Photogrammetry softwares are incredible. They can turn a bunch of pictures into a 3D model. Although I do that only for fun, photogrammetry is used by surveyors, architects, civil engineers, disaster relief coordinators, video game creators, cinema and in a lot of other fields. Pictures can be taken from the ground, from the air (with a drone), or both. They can also be enhanced with RTK GPS (like a standard GPS but with centimeter accuracy) and with LiDAR (like a laser rangefinder but rotating on 360° and capturing hundreds of thousands of points per second). Measurement can subsequently be taken with great precision. But to get started, a smartphone is more than enough. Browse more 3D models on my Sketchfab page.
