基于FPGA和ARM的图像采集系统设计

The Design of Image Acquisition System Based FPGA and ARM

为解决图像数据采集过程中对准确性和实时性的要求,给出了基于ARM和FPGA的图像数据采集系统的设计方法。系统利用CMOS图像采集传感器把外界的图像模拟信号转化为数字信号,采用FPGA控制图像传感器完成图像采集工作,通过ARM对FPGA采集的数据进行处理,并且利用嵌入式操作系统Linux实现对FPGA的实时控制。该系统功耗低、性能稳定,提高了图像采集的准确性和实时性。

In order to solve the question of accuracy and real-time in image data acquisition process,the method that designing image ac quisition system based FPGA and ARM is put forward.This system uses CMOS image sensor to capture image analog signals outside into digital signals,and uses FPGA to control image sensor to complete the work.It is to do with acquisition data through the control from ARM to FPGA,and use embedded Linux operation system to achieve real-time control of FPGA.This system is low power,high performance,do improve the accuracy and real-time.
