Each camera takes a picture of the person from different angles. The trick is that more than one camera takes a picture of the same point on the person from different angles. This redundancy is important. Using trigonometry, the computer can triangulate each point.
We have provided a photogrammetry 3D scan for you to download. The 3D-scan data is available in OBJ+JPEG format. You can view it, for example, with the free 3D Viewer Meshlab
Photogrammetry is not as accurate as other 3D scanning methods. But it is very inexpensive and creates a 3D scan with color. Theoretically, there is no limit to the size of the object that can be 3D-scanned. Objects ranging in size from a mouse to a planet can be 3D-scanned using photogrammetry. A 3D-scanning booth can usually accommodate objects as large as 2m³ meters.
Holocreators offers professional 3D-scanning and reverse engineering services. We also offer 3D-scanning using photogrammetry. Whether you want to create a 3D figure or aerial3D models using drones, we would love to help you with your project.
We make videos about 3D-scanning and reverse engineering. We will happily inform you when a new video goes online.
