Freehand Laser Scanning Using Mobile Phone [PDF]
Procedings of the British Machine Vision Conference 2015, 2015 3D scanners are growing in their popularity as many new applications and products are becoming a commodity. These applications are often tethered to a computer and/or require expensive and specialized hardware. In this note we demonstrate that it is possible to achieve good 3D reconstruction on a mobile device.
