Abstract

    This study presents a robust approach to reconstructing a three dimensional (3-D) translucent object using a single time-of-flight depth

camera with simple user marks. In this study, we introduce a ground plane and piece-wise linear surface model as priors and construct

a robust 3-D reconstruction framework for translucent objects. These two depth priors are combined with the depth error model built

on the time-of-flight principle. Extensive evaluation of various real data reveals that the proposed method substantially improves the

accuracy and reliability of 3-D reconstruction for translucent objects.
