Abstract:

为了克服现有光眼检测法和模拟视频检测法的不足,研制一种新的基于互补式金氧半导体工艺(Complementarymetal-oxide-semiconductor,CMOS)的图像传感器智能错帖检测系统,其硬件将CMOS图像传感器、数字信号处理器(Digitalsignal processor,DSP)和可编程逻辑器件(Complex programmable logic device,CPLD)集成在一起,作为图像采集和处理的核心单元,另外还包括通用串行总线(Universal serial bus,USB)、串口和存储器等辅助电路.检测方法采用反向传播网络(Backpropagation network,BP网络)和矩不变量建立错帖识别算法,内嵌在数字信号处理器中,算法适合于文字、图文和图形等多类书帖,检测精度更高.算法参数估计试验表明,相对旋转角在±7°范围内时,检测准确率约为98%.
