Apple’s FaceID system uses infrared depth-sensing technology to authenticate people via their faces. It can also be used for simple 3D scanning, and [Scott Yu-Jan] found a better way to do that.
The main problem with using an iPhone as a 3D scanner in this manner is that the sensor is built into the front side of the device. It’s great for scanning your own face, but if you’re trying to scan an object, you can no longer see the iPhone’s screen. [Scott] solved this problem by slapping together a handheld 3D printed device to hold the iPhone along with an external monitor. This allowed Scott to scan while still seeing what was going on.
Having noticed that some of the 3D scanning apps produced strange, glitchy results when scanning faces, [Scott] decided to innovate artistically. He employed [Andrea] to model, took some scans, and Photoshopped the results into some impressive posters.
Overall, [Scott] demonstrates that it’s relatively easy to repurpose the iPhone for improved 3D scanning. With a simple design, he has a handheld scanner that works way better than just the phone on its own. Alternatively, consider getting into photogrammetry instead.
