3D Object modeling by phase shifting Profilometry A performance comparison between Sinusoidal and saw-tooth fringe pattern

Abstract

The 3D reconstruction of rigid objects using Phase Shift Profilometry(PSP) technique is one of the cornerstones of computer vision. Intensive research have been carried out on optimizing algorithm to increase the accuracy and efficiency. Different experimental results have been presented using different fringe patterns. So, this thesis work primarily focuses on experiment to find the characteristics of fringe patterns and their effect on 3D reconstruction in identical condition. Two fringe patterns sinusoidal and saw-tooth have been taken for comparison. This thesis work presents the comparative result of 3D reconstruction in different objects. Experiment was done on two rigid objects dummy mannequin head and triangular shaped piece of wood.
