Mario Lukas’ girlfriend is an archaeologist. Part of her job is to catalogue relics from digs and Mario deduced that what she could do with is a handheld, portable 3D scanner. So, he decided to build one using a Raspberry Pi 2, a Kinect scanning bar and a PiTFT. He’s used a library called Libfreenect on the software side and is currently at the proof-of-concept stage. You can see a video of the proof-of-concept (you might want to mute the audio – it’s a bit offensive on the ears) and read more here, including a link to instructions to help you compile the library you need.
