我们准确地捕捉一个人的发型的形状和外观。我们使用三角测量和扫描与平面的光的几何形状。多台投影仪和摄像机解决了头发反射率和复杂几何形状带来的挑战。我们介绍了使用结构张量来推断头发表面和头皮之间的隐藏几何。我们的三角测量方法提供了大量的精度提高，我们能够测量复杂的头发几何形状，包括复杂的卷曲和凹陷。为了再现头发的外观，我们捕获六维反射场。我们介绍了一种新的反射插值技术，利用分析反射模型，以减轻交叉衰落的文物所造成的线性方法。我们的结果非常符合真实的发型，并可用于动画。
We accurately capture the shape and appearance of a person's hairstyle. We use triangulation and a sweep with planes of light for the geometry. Multiple projectors and cameras address the challenges raised by the reflectance and intricate geometry of hair. We introduce the use of structure tensors to infer the hidden geometry between the hair surface and the scalp. Our triangulation approach affords substantial accuracy improvement and we are able to measure elaborate hair geometry including complex curls and concavities. To reproduce the hair appearance, we capture a six-dimensional reflectance field. We introduce a new reflectance interpolation technique that leverages an analytical reflectance model to alleviate cross-fading artifacts caused by linear methods. Our results closely match the real hairstyles and can be used for animation.
