从测量数据中提取古塔的变形信息
Deformative Information of Ancient Pagoda Extracted from Measured Data
摘要
Abstract
For the protection of cultural relics, deformative information of ancient pagoda is extracted from a large number of measured data. Combining concepts such as centroid, barycenter and pericenter, the paper designs the general algorithm to determine each layer center position of pagoda, and presents the remedial measures when data is flawed. In order to extract the gradient information, the author establishes symmetrical fitting model of space linear, and provides simple and practical objective function and method to search its initial value optimization. To avoid information distortion, a formula is conducted to calculate the distortion with raw data directly. After further analysis, misunderstanding is made clear in some popular algorithm.关键词
