| 摘 要： | 探讨在虚拟世界的建造中不规则物体表面纹理的提取和映射.通过环绕实体拍照的方式采集实体的表面纹理.为达到模型坐标点和照片坐标点的一一对应的目的,建立了模型坐标系、相机坐标系、照片坐标系以及不同坐标系之间的转化关系式.为减少映射的变形,对每一个三角面片采用计算其面片法向量和相机的位置关系来确定最佳的纹理图像,通过多角度映射达到纹理重建的目的.

| Abstract: | The extraction and mapping of texture of non-regular object faces used in the construction of virtual world are discussed.To start with,we extract the texture of object surfaces by taking photos around it.Next,we set up three coordinate systems and obtain a transform formula among them to establish a one by one corresponding relationship between points in model coordinate system and in photocoordinate system.To reduce the distortion in the process of texture mapping,we can decide the best image among all the photos through calculating the position relationship between the normal vector of each small face patch and camera position vectors.So we complete 3D texture reconstruction of object surfaces through several-angle texture mapping technology.texture reconstruction;texture collection;mapping transformation;particle;normal vector |
