基于 SoC FPGA 的文字分割系统设计
Design of the text segmentation system based on SoC FPGA
摘要
Abstract
In order to solve the problems of power consumption,portability,real-time and volume limitation of image acquisition and processing system based on PC,the text segmentation system based on SoC FPGA in-built hard-core ARM is designed.By co-design of hardware and software based on SoC FPGA hardware platform and embedded Linux development,the system realizes the image ac-quisition of the CMOS sensor,storage of SDRAM,data communication of two-port RAM and VGA display.In the meanwhile,ARM-based HPS controls dual-port RAM to read or write image data and the image preprocessing and watershed algorithm are implemented.Experimental results show that this system has the high accuracy of text segmentation and the real-time processing average speed of one image is 0.87 s,which is 0.84 and 4.52 times faster than that of PC-based MATLAB environment and SOPC system based on NIOS II respectively.This system has the advantages of flexibility,high speed and good portability and there is the real-time image acquisition and processing system.关键词
