摘　　要：针对真实物体进行三维数字化重建的工程中,物体的空间位置及色彩等特征的数据采集始终是一项困难的,同时却又是十分重要的工作,设计的三维光学数字成像系统可以同时采集物体在同一个方向的深度图像和与它精确对应的纹理图像,在深度图像合成的同时进行纹理图像的融合。在进行多视角的纹理图像融合时,对权函数的设定提出了新的准则,使融合后的纹理图像更加逼真,可以产生高真实感的物体三维数字化模型。In the process of building digital models for real objects, the data collecting of spatial, colorific characters of the multi-dimension objects were always a hard, but very important job. A new system for creating photorealistic textured 3D models was proposed. Using the system, both range image and its exact corresponding texture from one direction could be acquired simultaneously. To integrate 3D shape between the range images and to blend the corresponding textures had been at the same time. An original weight function was introduced into blending textures and it had made the blended texture image better and generated highly realistic 3D models.
