摘要
针对当前图像采集存储系统功耗高、图片质量差、体积大的问题,提出了一种低功耗、高性能的微型系统设计方案。在硬件设计中,采用GC2053 CMOS图像传感器作为图像采集前端;控制及处理模块中HI3516EV200 SOC作为主芯片,外接一个SPI NOR FLASH作为软件系统的存储介质;64 GB的TF卡作为采集图像的存储单元;同时介绍了系统时钟、复位及电源模块的设计。在软件设计中,采用ubuntu系统作为嵌入式开发环境,介绍了软件系统层次、图像的软件处理流程和ISP(图像信号处理)模块的处理过程。实验结果表明:该系统体积小,运行稳定,采集的图像清晰流畅。
Aiming at the problems of high power consumption,poor quality and large volume of image acquisition and storage system,a low power consumption and high performance micro-system design scheme were proposed.In the hardware design,GC2053 CMOS image sensor was adopted as the front end of image acquisition.In the control and processing module,HI3516EV200 SOC served as the main chip,and SPI NOR FLASH was attached as the storage medium of the software system.The 64 GB TF card served as a storage unit for image acquisition.The design of system clock,reset and power supply module were introduced as well.In the software design,the ubuntu system was adopted as the embedded development environment,and the software system level,image software processing flow and ISP(image signal processing)module processing process were introduced.The experimental results show that the system is small in size,stable in operation,and the collected images are clear and smooth.
