Truncated signed distance function: Experiments on voxel size

Abstract

Real-time 3D reconstruction is a hot topic in current research. Several popular approaches are based on the truncated signed distance function (TSDF), a volumetric scene representation that allows for integration of multiple depth images taken from different viewpoints. Aiming at a deeper understanding of TSDF we discuss its parameters, conduct experiments on the influence of voxel size on reconstruction accuracy and derive practical recommendations.
