3D Geometric Hair Reconstruction Using White Structure-of-Light Coding

In order to achieve accurate and fast 3D modeling in hair region, as well as present a feasible technical scheme for hair modeling, we build a 3D geometric data-capturing and reconstruction system based on white structure-of-light technique and proposed a robust high frame-rate binary coding algorithm. This system consists of four self-made structure-of-light scanners, which are configured to effectively cover the whole surface of a head. Because of the high frame-rate coding algorithm, it could scan the head in 1 second and improve the boundary distinctness of projected stripe to obtain sub-pixel data accuracy, and then reconstruct the geometric mesh with hair very quickly. The experiments show that the system produces high-quality 3D geometric hair results, achieving the state-of-the-art millimeter level accuracy, and demonstrate the effectiveness and robustness of the coding algorithm.
