摘要
阐述了建筑墙面纹理快速重建需要解决的问题和实现策略,并从实用、经济的角度出发,对纹理影像数据源的选择、获取方式,纹理快速提取系统的构建以及重建过程中影像方位元素获取、轮廓线影像匹配关键算法的实现等各方面进行了具体探讨,最后以数码相机拍摄的近景影像和直升机机载视频序列影像作为纹理数据源分别设计和实现了两个软件系统,进行了快速重建实验,并取得了较好的纹理重建效率和效果。
Abstract： In this paper, we not only ou to them toward rapid texture extraction tline key problems and propose reasonable solutions but also make specification on how to select image resource for texture, which way to take picture and wh set up. In addition, some effective algorithmics like De at kind of software system should be termining camera parameters, Matching building to its projection in images and so on, are detailed discussed and implemented in this paper. Last, taking two kind of image-one is close image taken by digital camera and another is image sequences captured by digital video on helicopter, as texture resource, we design and implment two software system to make experiment and gain encourage result.
