An open source 3D Scanner made with Raspberry Pi


Boris Landoni from Open Electronics writes about a new open source 3D Scanner made with Raspberry Pi:

This being said, we may move on to talk about our 3D scan approach, that consists in using a linear laser, that is, one capable of drawing a vertical line having a constant luminous intensity, and in shooting the images that have been determined by the light’s reflection on the object’s surface (that in this case is rotated) by means of a video camera; at each rotation degree (or fraction) corresponds a frame that is digitized and sent to a program capable of processing the surface of the scanned object. Usually, in these systems two lasers (tilted with respect to each other) are used, and the video camera is placed between the two. Our scanner is born out of an elaboration of the PiClop, an open project composed of a mechanics (whose parts to be 3D printed may be downloaded from thingiverse ) and of an electronics formed of the Raspberry Pi 2 board and its video camera; PiClop, as implied by the name, is a free interpretation, based on Ciclop’s Raspberry Pi 2 , a 3D commercial laser scanner and a video camera, supplied with a rotating plate.

  1. However innocent it may be, I’m not impressed by the choice made by the creator of the image. Now, I’m not the most politically correct of persons, but the image still made me wince mentally…

    1. You’d wince at a 3d print of venus de milo?
      I guess you’d be in trouble in a museum with classical and neoclassical art

      1. That’s not the goddamn Venus de Milo, and it’s not anywhere close to the level of the Venus de Milo. Nor does it have the cultural significance. It’s not the product of a serious sculptor with something to say. It’s a deliberately exaggerated mass-produced toy figurine designed purely to titillate… the sort of thing some beer-swilling dudebro would have lying around.

        And choosing it as the face of your project makes it obvious you’re an exclusionary asshole. Which I guess is a public service of a sort.

  2. The Dual fixed laser has been done and found wanting. Theres a lot of topologies that this system will simply miss, particularly concave and multi pillar shapes, such as pairs of legs.

    1. Now, now Max, I think you can do better than attempt some lame baiting… :-p
      Good, some folks have been successfully prodded to offer some opinions.
      But really, what do the others think? Do tell. :-) Why do the lasers point the way they point?
      Why can’t they use standard 3D thingies, like the usual rabbit, for instance?
