虹膜弹性运动的不对等性
Inhomogeneity of Iris Elastic Motion
摘要: 随着图片采集设备的发展，虹膜识别对特征点定位的准确性要求也越来越高，传统的橡胶板模型已无法满足虹膜识别对精准度的要求。为削弱瞳孔扩张和收缩运动对识别结果的影响，本文根据开大肌和括约肌组织结构的不同，提出了一种虹膜向外、向内弹性变化的不对等性模型。该模型从组织动力学入手，结合不同运动状态下虹膜组织弹性变化的特点，分析应力和剪应力在形变过程中占位的重要程度，深入研究虹膜组织扩张和收缩运动的不对等性。
Abstract: With the development of image acquisition equipment, the accuracy of iris recognition for feature point positioning is higher and higher, and the traditional rubber plate model cannot meet the requirements of iris recognition on accuracy. In order to weaken the effect of pupil dilatation and contraction on the recognition results, an iris external and inward elasticity model is proposed according to the different structure of the open major muscle and the sphincter. This model starts with the tissue dynamics and analyzes the importance of the stress and shear stress in the deformation process by combining the characteristics of the elastic changes of iris tissue under different moving states. The inhomogeneity of the expansion and contraction of iris tissue is studied in depth.
