基于三维扫描技术的古建筑数字建构与虚拟展示实验

Experiment on digital modeling and virtual exhibition for ancient architectures based on 3D scanning technology

通过近年新兴的测绘技术——三维激光扫描技术对古建筑进行破坏小、速度快、精度高的实地测绘,可以得到相对传统测绘更为精确的点云数据。接下来,对测绘结果进行校核统计。一方面根据测稿数据及现场照片等资料,在Auto CAD软件平台上进行精确到毫米的绘制,生成平面、剖面和内部细部。另一方面对得到的电子数据进行后续处理,在点云数据的基础上,通过Auto CAD平台,进行删减、蒙描,或通过捕捉点直接绘制生成立面及其细部。后期借助参数化平台对点云数据进行处理,实现古建筑的三维再现。最后通过虚拟现实技术再现古建筑风貌,使得人们接触古建筑的门槛大幅度降低。

Through three dimensional laser scanning technology with small damage, fast speed and high precision for the field of ancient buildings mapping, we can get a more accurate point cloud data.Next to check the results of the survey statistics.On the one hand, according to the data of the manuscript and the data of the field photos, on the AutoCAD software platform for accurate to the millimeter of drawing, generating plane, section and internal detail. On the other hand to get the electronic data for subsequent processing, based on the point cloud data, through the AutoCAD platform, to cut, cast, or through the capture point directly to generate elevation and detail drawing. In the late stage, the point cloud data is processed by the parameterized platform to realize the 3D reconstruction of the ancient architecture. Finally through the virtual reality technology to reproduce the ancient architectural style.The threshold for people to access the ancient buildings is greatly reduced.
