Active light-based 3D capture

Inside Politecnico di Milano a 3D scanning (light-based technique) laboratory was carried out. We choose an object with certain complexity and organic shapes in order to capture digital information about the shape of it.  

The objective also involved the digital post-processing in order to have an accurate 3D model from the physical one.

  • Reference object: Toy shaped gun
  • Laser equipment: Minolta Vivid910
  • Post processing software: Polyworks
  • Render Software: Keyshot

Passive 3D Capture

Photogrametry is the science that allows to obtain an accurate geometric measurement thanks to a set of images the object of interest taken from different positions. For this purpose an object with great color contrast and texture was chosen.

After taking aprpoximately 80 pictures the post procesing was carried out on a software specialized in photo scanning and another one for rendering.

  • Reference object: Toy shaped fish
  • Camera: Nikon D3100
  • Post processing software: Agisoft Photoscan
  • Render Software: Keyshot
