摘要
在计算机图形学领域,准确展现材质表面的完整颜色信息特别是其纹理特征,是实现真实物体三维数字化的关键所在.本文首先从获取材质表面全方位外观的函数模型与测量技术出发,全面综述了材质表面反射特性的演进过程,并着重分析了双向反射分布函数(BRDF)、空间变化双向反射分布函数(SVBRDF)以及双向纹理函数(BTF)模型的独特之处.其次,汇总并回溯了材质表面全色貌获取技术的发展历程,特别是在不同机械设计的全色貌采集设备基础上,进行了分类总结,主要分为三类:机械臂式、棱镜式以及相机矩阵式.最后,总结了全色貌获取技术的当前发展方向,并对材质表面全色貌获取技术的未来趋势进行了展望,旨在为该领域的持续进步提供参考和预见.
Abstract
In the domains of computer graphics,the expression of total color appearance of material surfaces,especially the expression of material texture information,is recognized as essential for realizing the three-dimensional digitalization of real objects.Function models and measurement techniques for capturing the total color appearance of material surfaces were examined in this paper.A comprehensive review was conducted on the evolution of material surface reflection characteristics,with a focus placed on the detailed analysis of the unique attributes associated with the Bidirectional Reflectance Distribution Function (BRDF),Spatially-Varying BRDF (SVBRDF),and Bidirectional Texture Function (BTF) models.The development of technologies for measuring the total color appearance of material surfaces was also consolidated and retraced.Advancements were classified and summarized based on the differing mechanical designs of appearance capture devices,which were primarily categorized into robotic arm-based systems,prism-based systems,and camera array systems.The current trajectory of total color appearance acquisition techniques was encapsulated,and insights into future trends in this domain were ventured.Through these efforts,it aims to provide a roadmap and foresight for sustained advancements in the field.
