My Cardboard 3Dbody with 3D Laser Scanner

Assignement Project Description

Use software to obtain a body-figure and a digital fabrication process to produce it (the production happens in groups of 3-4)

Use a 3D Laser Scanner as part of students' practical work in order to obtain a better rendering of the 3D object.

1/ PHOTOS SCANNING OF MY BODY WITH 3D LASER SCANNER KONICA MINOLTA

The living model must move as little as possible. Close your eyes for the scanner beam. Favour light clothing that attracts light.

2/ ASSEMBLY OF THE DIFFERENT SCAN LAYERS ON THE PROPRIETARY LASER SCANNER SOFTWARE

This step is quite tedious and the longer the scan takes, the longer the 3D object will take. The 3D laser scanner does not locate the front of the object's backside, so it must be given precise reference points to add the slaps between them.

Improvements and Challenges

The difference in precision is important between the 3D scan app and 3D laser scan.

Processing the 3D image takes a long time (about 10 hours).

The rendering corresponds to my expectations, the dimensions correspond to a few centimetres ready.

The next protoypes will have access to a search for custom busts production. Test the paid version of Scan 3D APP.
