摘要
为了实现对头发区域三维模型的快速精确重建,对发型建模提供可行技术方案,利用白色结构光技术搭建三维发型采集系统,并提出一种高频二值条纹的结构光编码算法.该系统使用了4台自制的白色结构光扫描仪,通过预先配置空间位置实现对头部区域的有效覆盖,并利用高频二值条纹编码算法在1s内采集头部数据,提高结构光条纹边缘可辨识度,实现亚像素级数据精度,之后快速重建出包括发型在内的三维头部网格模型.实验结果表明,重建后的三维发型具有高几何精度,达到了当前最优的毫米级别,并验证了采集系统特别是编码算法的有效性和鲁棒性.
In order to achieve accurate and fast3D modeling in hair region,as well as present a feasible technicalscheme for hair modeling,we build a3D geometric data-capturing and reconstruction system based on whitestructure-of-light technique and proposed a robust high frame-rate binary coding algorithm.This system consistsof four self-made structure-of-light scanners,which are configured to effectively cover the whole surface of ahead.Because of the high frame-rate coding algorithm,it could scan the head in1second and improve the boundarydistinctness of projected stripe to obtain sub-pixel data accuracy,and then reconstruct the geometric meshwith hair very quickly.The experiments show that the system produces high-quality3D geometric hair results,achieving the state-of-the-art millimeter level accuracy,and demonstrate the effectiveness and robustness of thecoding algorithm.
