3D scanner can cost hundreds of tens of thousands of euros. The necessary sensors is now also in some smartphones and tablets. For Apple, the iPhones X, XS, XS Max and XR and the current iPad Pro have a so-called TruedEPTH camera system. The tiny system sits clearly visibly at the top of the screen and actually serves face recognition to unlock the candy or animation of emojis ("Animojis"To).
The start-up standard Cyborg has the technology now with its free "Capture"-App as a 3D scanner misinterpreted. This works because the system senses faces three-dimensionally so as not to be overlicked by a blobing photo. For this purpose, a point projector creates an invisible infrared pattern on the object, an infrared lamp illuminates it, and the infrared camera takes the signal.
Now start the app and stop an object in front of the camera, it will first be released automatically. This works fine, sometimes less well, depending on the complexity of the object. Then you print the blossom and turns the object slowly. However, the fingers like to join. So useful goods the purchase of a turntable.
