基于DSP的纸张缺陷实时检测系统设计

基于DSP的纸张缺陷检测系统,分别对该系统的硬件和软件部分进行介绍。硬件部分采用高性能的DSP芯片作为图像处理的核心部分,为缺陷检测的实时性提供了保证;软件部分采用支持向量机算法,克服了传统方法的大样本要求和维数灾难及局部极小问题,又把非线性空间的问题转换到线性空间,降低了算法的复杂度,提高了计算速度。通过将支持向量机识别算法嵌入到高性能DSP芯片中,很好地实现了纸张缺陷的实时检测。

Design of Paper Defect Real Time Detecting System Based on DSP

A paper defect detecting system based on DSP,including its hardware part and software part was introduced.High performance DSP chip was used as the key part of imagine processing in the hardware,it assures the real time defect testing of the system.The software part is the popular Support Vector Machine arithmetic.This arithmetic is based on statistics theory,which conquers the requiring of large sample and dimension mischance and the problem of local infinitesimal.This arithmetic turns the computing from nolinear space to linear space,reducing the complexity of the arithmetic and upgrading the speed of computing.In this paper the Support Vector Machine arithmetic was inserted into high performance DSPs to achieve the real time detecting of paper defect,and the results of experiment proved that this method is effective.
