| 摘 要： | 根据变形观测的位移矢量，识别菜体及其运动模式是变形分析一项重要内容，以往的作法是根据矢量作图人工判断变形体，然后选择适当的模式进行拟合。本文提出一种在点位邻接拓扑关系加其他先验信息约束的识别思想及相应算法别人，从而可实现变表模式的自动识别。最后的算例说明了该算法的实现过程，有效性及潜在意义。

| Abstract: | Recognizing the moving blocks and their movement models of deformation object is an important content in deformation analysis. The traditional method of the deformation model recognizing is to draw the moving vectors of the observed points, so that to judge the moving blocks artificially,and to select suitable movement models. This paper introduces a new idea of recognizing the deformation models and corresponding algorithm, which is based on constraints of topological relationships and other priori information. And the model recognizing can be automatically accomplished by the new method. Finally, an example is given successfully. |
