Abstract

This article will discuss how to improve the ability to protect the collection mural with Lidar and Geographic Information System (GIS) technology. Firstly, we gain three dimensional point clouds through the Lidar technology, and make high-precision Digital Orthophoto Map (DOM), which has the same scale as the real collection mural. Secondly, the spatial disease database will be built based on the DOM of collection mural with the GIS technology. Then we can get some useful dataset for protecting collection mural, such as disease map and trend map. Disease map, based on some spatial analysis and spatial statistics, will tell you where the disease is, and how serious the disease is. Lastly, but importantly, we can classify the disease grade based on the collection mural with decision tree. So protector of collection mural knows what’s the most serious disease. It is better than the traditional methods both in accuracy and efficiency. Finally, this article has confirmed the related method efficiency and the precision in the collection mural of Greatly Summons Temple.
激光雷达与GIS技术在馆藏壁画保护中的应用
本文将讨论如何利用激光雷达和地理信息系统(GIS)技术来提高收藏壁画的保护能力。首先,通过激光雷达技术获取三维点云,制作出与真实收藏壁画比例尺相同的高精度数字正射影像图(DOM)。其次,在收集壁画DOM的基础上,利用GIS技术建立空间疾病数据库;从而得到一些有用的数据集,如疾病图和趋势图。疾病地图,基于一些空间分析和空间统计,会告诉你疾病在哪里,疾病有多严重。最后,利用决策树的方法对疾病等级进行分类。所以收藏壁画的保护者知道什么是最严重的疾病。该方法在精度和效率上都优于传统方法。最后,本文在大召寺收藏壁画中验证了相关方法的有效性和准确性。
