High-Accuracy Globally Consistent Surface Reconstruction Using Fringe Projection Profilometry
Sensors, 2019 This paper presents a high-accuracy method for globally consistent surface reconstruction using a single fringe projection profilometry (FPP) sensor. To solve the accumulated sensor pose estimation error problem encountered in a long scanning trajectory,
