摘　　要：提出了一种线性弹性模型用以解决具有形变的平面轮廓匹配问题．这种匹配方法克服了弹性匹配方法存在的计算复杂或内部相互制约力不强的缺陷，表现出非常强的鲁棒性．整个匹配过程是一个由粗至精的动态迭代过程．在所有弹簧结点上都进行外力计算．在外力的作用下，匹配过程能以很快的速度进行收敛．In the paper a linear elastic model is proposed which is used in solving the planar contour registration problems between deformed objects. The matching method overcomes some deficiencies in traditional elastic matching approaches and shows high robustness. Here the registration is carried out in a dynamic iterative process from coarse to fine. This process converges with high speed under the external forces which are calculated at every node of the elastic string.
