Removal of specular highlights in 3D reconstruction based on fringe projection complementarity
Abstract:
In the field of 3D reconstruction, accurately and effectively removing specular highlights remains a challenging problem. Existing highlight removal methods mainly focus on processing each image independently, neglecting the interrelationship among images. This paper explores the correlations between different images and, within the traditional three-frequency four-step phase-shifting method of fringe projection profilometry (FPP), leverages the complementarity among images to propose a novel highlight removal approach. Experimental results demonstrate that the proposed method significantly reduces unreliable pixels caused by manual fitting compared to previous techniques, thereby enhancing the accuracy of 3D measurements.
