[Abstract]:Image processing technology has been widely used in biomedical, industrial production, military and public security fields. Traditional image processing platforms are mostly PC oriented, large in volume, high in power consumption and complex in development.The rapid development of microelectronics technology promotes the development of image processing platform in the direction of intelligence, digitization and miniaturization. The emergence of embedded system and its application in image processing platform further shorten the second development period of image processing platform.Improve the performance of image processing platform.Based on the research of various embedded image processing platform schemes, this paper proposes a design scheme of embedded real-time image processing platform based on ARM and FPGA, combined with the characteristics of ARM core board and FPGA development technology.FPGA is introduced to realize the real-time transmission and processing of high-resolution images and the large screen display of high-resolution images. The embedded operating system is introduced into the image processing platform for the first time with the help of the ARM hardware platform.It greatly simplifies the application and development of real-time image processing platform and provides a new idea for the development of real-time image processing platform.In this paper, the hardware circuit is designed which is composed of ARM slave module and real time image acquisition module. The peripheral interface and real time image acquisition module are controlled by S3C2440A ARM microprocessor.EP1C3T144I7N FPGA chip is used to control the timing of real-time image buffer interface to realize high resolution real-time image output, and SAA7113H image decoding chip is used to realize real-time image acquisition and decoding of simulated CCD.And embed the customized Win CE embedded operating system on the self-designed hardware platform, designed the stream interface driver for real-time image acquisition based on the Win CE system. Finally, according to the requirements of the industrial application field,The design function of the platform is verified by running the application software of measuring the object length on the designed software and hardware platform.The platform integrates general AV video interface and several USB interfaces with RS-232 serial port and VGA interface. The real-time image acquisition and processing are realized. The resolution of output video image reaches 800 脳 600,60Hz.The platform adopts modularized hardware design and software design based on embedded operating system, which has the advantages of easy expansion, small volume, low power consumption, convenient transplantation and short secondary development cycle.
