考古元素的三维调查和虚拟模型的构建使我们能够重建历史遗址。它们为选择特定的建筑工艺提供了有用的数据。摄影测量和地面激光扫描（TLS）是获得综合遗产模型最常用的技术。这些技术提供了大量的数据，这些数据只能通过原始形状替换来管理，从而获得更简单的模型和元素的显式几何形状。统计和稳健的方法用于这种替代，从而避免了由于测量的常见误差。在这些方法中，使用最广泛的是最小平方中位数（lmed）和RANSAC方法。另一种计算方法是基于进化型算法的递归过程，以调整模型以适应捕获的数据。本文介绍了两种曲面计算方法，以确定位于西西里岛塞林内特考古公园的神庙G柱轴的造型。(C) 2012 Elsevier Ltd.版权所有。
3D surveys of archaeological elements and the construction of virtual models enable us to reconstruct historical sites. They provide useful data to select specific building processes.Photogrammetry and Terrestrial Laser Scanning (TLS) are the most common techniques to obtain synthetically heritage models. These techniques provide massive data which can only be managed by replacing them by primitive shapes, thereby obtaining more simple models and the explicit geometry of the element. Statistical and robust methods are used for this substitution, thereby avoiding the common errors due to measuring. Of these methods, the most widely used are the least-median-of-squares (LMedS) and the RANSAC method.Another computation method consists in recursive processes based on evolutive-type algorithms to adjust the model to the data captured.This paper describes two surface computation methodologies to determine the modelling of a column shaft located in temple G of the archaeological park of Selinunte (Sicily).
