摘要
虚拟现实技术有着广泛的应用背景,建立实体模型是其首要步骤。传统的几何建模方法费时、而且难以表现实体表面的真实特征。这里提出、实现了一种便捷的虚拟现实建模方法。首先对待建模对象进行用摄像,并将照片输入到计算机内,经过特征匹配、相机标定及纹理映射等步骤,最终得到具有表面纹理的实体模型。此方法简单易行,文中给出了建模实例,验证了所提出的方法。
Traditional way to construct realis tic VRML models is tedious and expensive .Anew approach is put forward to settle the problem onl y using a still dingital camera.At fi rst,images of the object are taken th rough a still digital camera and conveyed t o a computer.After image process,th e feature points between two adjacen t images are matched through a semi -au tomatic method,and the formulation of cameras' displacements and3D positions is solved through a optima l iteration algorithm.At last,the t extures of the surface are mapped fro m images.A example is given,and the re sult is satisfied.
