摘要
针对书刊印刷品的书帖检测过程,设计了一套改进的书帖错帖检测系统.系统的硬件由CCD传感器、数字信号处理器DSP和可编程逻辑器件CPLD构成,实现书帖信息的采集与处理;软件采用改进的SIFT检测算法,实现对书帖的准确并快速检测.给出了系统的硬件框图及软件算法的原理以及系统的工作流程图.与传统的SIFT算法相比,改进后的检测算法检测一张书帖的平均时间由原来的40ms降低为1ms,检测准确率高达98%.
For the paper detection process in printed publications, design a paper detection system. The hardware of the system is composed of CCD sensor, digital signal processor DSP and programmable logic device CPLD, which could complete the paper acquisition and processing process. Software adopts the im- proved Scale Invariant Feature Transform detection algorithm to complete the accurate and rapid detection. Paper gives the hardware of paper detection system, the principle of the algorithm and the flow chart of this system. Compared with the traditional SIFT algorithm, the average time of the improved detection algo- rithm for detection of a book decreased from the original 40ms to 1ms. The detection accuracy rate reached 98%.
