Freehand Laser Scanning Using Mobile Phone

Ron Slossberg, Aaron Wetzler and Ron Kimmel

Abstract

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. We describe a novel approach for mobile phone scanning which utilizes a smart-phone and cheap laser line pointer attached to the phone using a 3D printed adapter. Non-linear multi-cale line filtering is used to detect the center of the projected laser beam in each frame with sub-pixel accuracy. The line location coupled with the estimated phone position and orientation in 3D space, obtained from publicly available SLAM libraries and marker tracking, permits us to perform a 3D reconstruction of a point cloud of the observed objects. Color and texture are extracted for every point along the scanned line point by projecting the reconstructed points back onto previous keyframed images. We validate the proposed method by comparing the reconstruction error to the ground truth obtained from an industrial laser scanner.
