	<span style=\"font-size:14px;\">HS光流法是基于机器视觉的运动目标方法中的主流方法之一，1981年由Horn和Schunck等人提出光流约束方程，对光流计算奠定了深厚的基础。本文通过引入HS光流计算方法，生成待识别印章与存档印章的光流速度矢量场，再计算矢量误差的局域方差从而计算综合判定待识别印章的真伪。实验结果证明，HS光流法一定程度上可以鉴别真伪印章。<br />
The HS optical flow method is one of the mainstream methods of moving target methods based on machine vision. In 1981, the optical flow constraint equation was proposed by Horn and Schunck <i>et al.</i>, which laid a deep foundation for optical flow calculation. In this paper, by introducing the HS optical flow calculation method, the optical flow velocity vector field of the seal to be identified and the archived seal is generated, and the local variance of the vector error is calculated to com-prehensively determine the authenticity of the seal to be identified. The experimental results prove that the HS optical flow method can discriminate authentic seals to a certain extent.</span>
