Photogrammetry is the use of photography in surveying and mapping to ascertain measurements between objects. By taking as many pictures of the subject in as many angles as possible, software is used to triangulate the points to form a 3D mesh, or shape, all the while capturing photo-realistic textures.

At Rabbit, we use a XYZ RGB scanner that enables us to capture high res images and then translate them into high detailed scans. This method is often used in the entertainment industry as it is the most effective way to capture actors and extras to generate Digital-Doubles for VFX purposes.

 
 

Last year, AR & Gaming studio Seamonster approached us to help them create an app for local furniture company @Home. They wanted people to experience their furniture via AR on mobile devices. We were asked to find an efficient way to 3D scan a large amount of furniture with varying sizes, colours and textures. With this in mind, we aimed to maintain the realistic look, allowing for texture/colour swap & maintaining a 1:1 scale while keeping digital models light for mobile use.
During this process, we:

  • Explored different 3D scanning techniques for the requirements before settling on photogrammetry.

    • Designed and fabricated a rig that would enable us to scan with limited amount of cameras and fit large and small pieces of furniture on it.

      • Used a range of digital manufacturing methods to make up the rig: 3 axis CNC cutting, aluminium machining, laser cutting and 3D printing.

        • Involved other teams to work on re-topolizing and integration with Unity.
