摘要
为解决常规船舶航行视频采集系统在复杂海况环境下,存在视频采集分辨能力较低的不足,提出了基于FPGA的船舶航行视频采集系统设计与实现。依托船舶航行视频采集系统执行机构设计、控制电路设计,实现了系统硬件设计;基于船舶航行视频采集系统网关结构设计、控制过程设计,完成了系统软件设计,实现了FPGA的船舶航行视频采集系统设计。试验数据表明,提出的船舶航行视频采集系统较常规船舶航行视频采集系统,视频采集分辨能力提高47.82%,适合在复杂海况下进行视频采集。
In order to solve the problem of low resolution of conventional ship navigation video acquisition system under complex sea conditions,a design and implementation of ship navigation video acquisition system based on FPGA is proposed.Based on the design of the executive mechanism and control circuit of the ship navigation video acquisition system,the hardware design of the system is realized;relying on the design of the gateway structure and control process of the ship navigation video acquisition system,the software design of the system is completed,and the design of the ship navigation video acquisition system based on FPGA is realized.The experimental data show that the proposed ship navigation video acquisition system improves the resolution of the video acquisition by 47.82%compared with the conventional ship navigation video acquisition system,and is suitable for the acquisition of navigation video in complex sea conditions.
