Jolar, from Oxford Hackspace, has come up with a great way of doing 3D scans that needn’t break the bank. He’s used four Raspberry Pi Zeros and 4 Pi cameras mounted to a triangular frame. Each camera is pointing at a slightly different angle and between them they capture a 3D image. The files are then uploaded to the Cloud and his laptop does the 3D image processing of the files. You can read more about the project over on Hackaday.IO.
