The study of 3D laser scanning technology in Category Conservation is one of the hot researches in recent years. Through the high-speed laser scanning, catching the 3D data of an object in large-scale with high efficiency, high accuracy and excellent resolution, is a new way in 3D reconstruction and image data acquisition. The method has achieved good results through the experiment.

利用三维激光扫描快速、高精度、非接触、直接获取研究对象表面空间三维数据的技术优势,对汶川地震遗址三维虚拟重建进行应用研究。对震后不规则建筑物点云数据的分块拼接、处理,以及三维模型的真实再现进行技术探讨和实践,为震后灾害遗址全貌重现,地震工业遗址纪念展示园区规划提供重要依据。
