中文摘要:
      针对传统黑白色选系统检测速度慢、集成度低等问题,设计了一种基于ZYNQ-7000系列全可编程SoC为核心的新型图像色选系统。采用软硬件协同设计的方法;首先在PL端实现了线阵CCD图像采集、图像预处理等功能,然后使用AXI接口,将补正后灰度值、气阀输出信号和设置参数缓存至DDR3 SDRAM存储器,最后在PS端移植嵌入式Linux操作系统,进行图像特征检测和人机交互。实验结果表明,该系统可有效对待筛选物料的特征值参数进行测量,并进行选别,运行稳定可靠,满足工业应用要求。
英文摘要:
      A new black and white color selection system based on ZYNQ-7000 series fully-programmable SoC is designed to solve the problem of slow detection speed and low integration of traditional black and white color selection system. Using hardware and software co-design methods, firstly linear CCD image acquisition, grayscale correction, threshold comparison and valve output are implemented on the PL side. Then using the AXI interface to cache the compensated grayscale value, valve output signal, and setup parameters to the DDR3 SDRAM memory, and finally The PS side is ported to an embedded Linux operating system for real-time display and human-computer interaction. The experimental results show that the system can effectively measure the eigenvalue parameters of the materials with screening, and carry out the selection, the operation is stable and reliable, and meets the requirements of industrial applications.
