ABSTRACT: In order to capture and storage video data real-time for
carrier-based photoelectric warning system, An acquisition and
storage system based on FPGA is designed. To complete the asynchronous
interface timing of the camera and the storage system, the video data which
come from infrared camera and visible light camera is stored to FIFO by FPGA,
and then four SDRAM as cache and ping-pong operation cache-data storage to the
CF card, this structure not only takes advantage of high-speed reading and
writing skills of CF card, but also to ensure the integrity of the video data.
In the final experiment proved that the system can be effectively applied to
ships the photoelectric warning scanning system, its performance fully meet the
needs of practical application.
