摘要
考古绘图是文化遗产的重要存档资料,传统方法由人工绘制得到,效率低、精度差。文中依据考古绘图的独特需求,针对陶土类文化遗存数字化三维模型,提出一种自动化生成考古线图的方法。该方法采用扫描得到的兵马俑碎片三维模型,预处理后提取三维模型的轮廓线和脊线特征,并据此生成其考古线图。该方法从数学和算法角度上可为自动生成矢量线图的具体实现提供理论依据,具有视角可变、可用性强的特点,显著提高了考古绘图效率。
Archaeological drawing is an important archive of heritage which traditional method is made by manual work,with low effi-ciency and poor precision. In this paper,based on the unique needs of archaeological drawing for clay class cultural relics digital 3d mod-el,put forward a method of automatically obtaining the archaeological line chart. The method uses a scanned fragments of Terracotta three-dimensional model,after pretreatment to extract the 3d model of contour line and ridge line features,and obtain the archaeology chart with it. The method from the angle of mathematics and algorithms could be used to automatically obtain the vector diagram provides the theory basis for the implementation,it has the characteristics of the angle variable,strong usability, significantly improving the efficiency of archaeological drawing.
