摘要
设计了一种基于STM32F417的图像采集系统。以STM32F417微控制器为核心,通过CMOS图像传感器OV7670获取图像信息,在微控制器的控制下,将图像信息经FIFO缓存后存入SD卡中,并通过LCD实时预览。该系统硬件资源精简,采集的图像显示清晰,可扩展性强,适合便携式图像采集系统使用。
An image acquisition system is designed based on STM32F417. Taking STM32F417 microcontroller as the core, the system ac quires image information by CMOS image sensor OV7670. The image information through FIFO buffer is put into SD card under the con trol of microcontroller, then the information is previewed on LCD in real time. The system has reduced hardware resource, clear collect ed image and high expansibility. It is used in portable image acquisition system.
