| 摘 要： | 为了快速获取物体表面反射属性数据和三维几何数据,研制了一套包括相机、光源、三维扫描仪、控制系统等的物体表面反射属性数据采集系统,在此基础上,提出一种单材质物体表面反射属性建模方法.该方法根据物体反射特性对漫反射与镜面反射分别建模,能够逼真地构造出物体表面反射属性模型,并且保证了参数求解的稳定性.最后设计并实现了反射属性模型编辑工具.实验结果表明,利用该编辑工具可以实时、可视地调整模型参数,从而满足用户对反射属性模型编辑的需求.

| Abstract: | We develop a system that consists of a digital camera, LED lights, a 3D scanner and a controlling system, to rapidly acquire the data of surface reflectance and 3D geometry of real objects. Given the acquiring data, we propose a reflection modeling algorithm for single-material object, which fits diffuse and specular parts respectively according to their reflectance, so that the object reflectance model can be reconstructed very well. Finally, we develop a real-time editing tool for users to modify the resu... |
