书籍装订中基于相位相关性的自适应梯标检测方法

目的针对传统人工检查书籍配帖是否合格的方法带来的劳动强度过大,且容易出错等问题,提出一种基于相位相关性的自适应梯标检测方法。方法通过相位相关配准技术,利用CCD摄像机采集到梯标视频帧,计算其与模板梯标的相位相关性,并进行2帧图像的配准,然后对2帧图像的帧差进行分析,从而判断配帖是否出错。结果实验结果显示,文中提出的方法可以减少合格配帖的误检率,还可以对不合格的配帖进行检测。结论文中所提出的方法可以提高配帖梯标检测的鲁棒性。

An Adaptive Signature Mark Detection Method Based on Phase Correlation for Bookbinding

The work aims to propose an adaptive signature mark detection method based on phase correlation regarding the problems of excessively high labor intensity caused by the traditional artificial examination for the normal book association and the error-prone situations. By means of the phase correlation registration technology, the phase correlation between the signature mark video frame captured by the CCD camera and the signature mark template was computed. Moreover, the 2-frame image registration was conducted, and then the frame difference of 2-frame image was analyzed, thus telling whether the association goes wrong. The experimental results showed that the proposed method could reduce the false detection rate for the normal association and it could also detect the abnormal association. The proposed method can improve the robustness of association signature mark.
