基于图像的三维重建在建筑遗产测绘中的应用

Applications of Image-based Modeling in Architectural Heritage Surveying

基于图像的三维重建在传统摄影测量的基础上结合了计算机视觉领域的自动化算法,有效弥补了三维激光扫描在成本、便携性、作业时间、色彩记录等方面的局限,是近年来国际上建筑遗产测绘领域的研究热点,但在我国的研究还刚刚起步。文章介绍了该技术的原理、研究现状、应用实例,该技术可使建筑遗产精细测绘拓展到更多地域、更多类型,并使采集的信息更为丰富,为修复等后续工作提供有力帮助。

Image-based modeling combines conventional photogrammetry with automated algorithms developed by computer vision community. It is a powerful supplement to 3 D laser scanning in terms of cost, portability, in-filed efficiency and chromatic documentation, as well as one of the research focuses in the field of architectural heritage surveying in recent years, while relevant studies are still in infancy in China. The article introduces the theory, state of art, and applications of the technology. The conclusions are image-based modeling that could facilitate to further work such as restoration by expanding high-definition architectural surveying to more areas and more types of architecture, as well as providing more abundant information.
