Design and implementation of image acquisition system based on ARM and Linux

摘要

Traditional image acquisition system has all the disadvantages of complex, bulky and inconvenient to carry. The embedded image processing system integrates all the functions of image capturing, displaying and processing as well as takeing the advantages of small size and low power consumption. According to the need of modern security monitoring system, a kind of image acquisition system based on ARM and Linux was designed. The system takes S3C2410(ARM9) as core to construct image acquisition and processing system with USB camera, LCD monitor and memory, and builds the necessary peripherals and communication interfaces to complete the design of hardware platform. Then drivers were composed and embedded Linux operating system was transplanted, eventually the functions of image data collection, display and storage were realized. The test results showed that acquisition images were clear and the system turned out to meet the requirement.
