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.
