How to display a 3D scan photogrammetry in Augmented Reality with an AR Code

Monday 21st of March 2022 06:17:28 AM |

AR Code allows you to upload your photogrammetric scans for easy AR rendering of your creations. You can then share them anywhere with their AR QR Codes.

What is a photogrammetric 3D scan?

A photogrammetry is a 3D capture of an object (or an environment) reconstructed from photos. To make a photogrammetry, it's necessary to photograph the object from all its angles, a video taken all around the object is ideal, it can then be broken down into images by the 3D reconstruction software. A base of more than 200 photos is a good start for a correct photogrammetry.

Photogrammetry and Augmented Reality

Augmented Reality is a technology that allows today's smartphone, and tomorrow's AR glasses, to reproduce 3D digital content in the user's field of vision.

A photogrammetry is after the reconstruction process a basic 3D file. It can then be easily displayed in an augmented reality environment. To easily display an AR photogrammetry, you will have to create an AR anchor which is most often based on an AR Code (Augmented Reality Code).

AR Code service to upload your photogrammetry

AR Code is a SaaS that allows you to upload your own 3D file to easily anchor them behind AR QR Codes. You can then manage your different AR experiences on the platform which provides statistics as well as specific functionalities for 3D creation or scan tracking.

Here is a demo video that shows the process of an AR photogrammetry display from the capture to the AR rendering.

Photogrammetry to AR Code Tutorial

AR QR Code photogrammetry

  1. Capture by taking a video all around the object (<40 seconds recommended)
  2. Process the photogrammetry with an Macbook M1 and the MacOS Photocatch software: Photocatch MacOS (You can use an other OS/photogrammetry software)
  3. Export the 3D model to a .dae file
  4. Open its textures in GIMP to reduce their size (to 1024*1024px), save them. (Not shown in the video)
  5. Import the 3D file into Blender: (Not shown in the video)
  6. Export the model in *.glb format
  7. Upload it to your AR Code Premium account :
