摘要 变形的几何分析一般包括三个步骤：变形模型识别、变形参数估计和模型诊断检查。与需要进一步阐述的第一个步骤不同，最后两个步骤已得到广泛讨论和详细记录。尽管模型识别方法或多或少是面向项目的，但本文给出了一般性考虑和技术，这些考虑和技术已在实践中证明是有用的。讨论了时间序列的趋势分析，以识别时域变形模型。提出了加权相似变换和分段逼近来识别空间域的变形模型。所有这些技术都通过示例进行说明。
AbstractThe geometrical analysis of deformations generally consists of three steps: identification of deformation models, estimation of deformation parameters, and diagnostic checking of the models. The last two steps have been widely discussed and well documented unlike the first one which needs further elaboration. This paper gives general considerations and techniques which have proved useful in practice though model identification methods are more or less project oriented. Trend analysis of time series is discussed for identification of a deformation model in time domain. The weighted similarity transformation and piecewise approximation are presented for identification of deformation models in space domain. All these techniques are illustrated with examples.
