Do-it-yourself 3D Scanning


Sebastian Korczak built his own 3D scanner with Blender, a line laser and an old recordplayer. I love these kind of projects!

I decided to execute my old idea of 3D scanner. I was surprised when I realized that digital camera, linear laser and Blender are enough for fast scanning of large objects with good precision. How it works? Cheap camera and linear laser (from simple laser level) are rotating about vertical axis, then python script is processing recorded video and calculating scanned points coordinates.

I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.


  1. really cool! -this plus a point cloud mesher + tesselation could just be wonderful er.. great :D for quick mesh generation :)

  2. This is brilliant and cheap soloution for 3d scanning. Must be perfect for recreating real enviroments for compositing 3d and video (camera tracking & co).


  3. I tried doing this or something similar once, and generated nice data-points but gave up because of time problems before being able to connect the data-points into useable meshes. Great work tho, good that people invent new things using blender, thumbs up:D

  4. A portrait of a geek's bedroom and the geek himself. How quaint. Err I can't believe i just said that. This is a really cool project. Just a profoundly uninteresting choice of subjects for the demo!

  5. wow what a great setup..thats really inventive ideas...great work!
    looks freaked out ..hope its as much fun operating it as it looks ..
    impressive!!! thumbsup

  6. it would be nice, if someone came up with an areal fringe projection (or structured light projection) project that imports its data directly into blender.

  7. some people are just to good.
    Do you sleep at night, do you have a life?
    This is crazy man.

    Come you have got to do a video tutorial you can't just let that lying here!

  8. Hi everybody,

    I sleep at night, I have interesting live, so many ideas, day in Poland has standard 24hours, I think about 3d scanner full integrated with Blender this year, but now I'm working with my thesis...
    Take care and happy blending!

  9. @TiPi: The Python Image Library is cross platform, he just linked to the windows version which is probably what he used.

    What I want to know is where the script that converts the sequence of images into a point cloud is!
