摘要
针对实时视频系统无法进行在线标注的问题,利用EP4CE115F29C7N高性能处理芯片、RS232串行通信和VGA显示技术,设计了一种基于FPGA串行通信的视频图像叠加系统。重点描述了系统中串行通信模块和VGA显示模块的硬件结构,对系统的工作流程和串行控制的软件设计进行了介绍。通过测试,该系统稳定可靠,在实际的工程测试中达到了预期效果。
To address the issue of online annotation problem of real-time video image system,a kind of video image overlay system based on serial communication of FPGA was designed on the basis of EP4CE115F29C7 N high performance processing chip,serial communication of RS232 and VGA display technology. In this paper,the design of hardware structure of serial communication module and VGA display module were mainly described. It also introduced the work flow and software of the serial control.Through the test,the system works stably and reliably,which also achieves the expected effect in the practical engineering test.
