摘要
针对目前汽车电子智能辅助系统的现状和市场需求,提出了一种基于多路视频解码复合技术和OSD显示技术的四路车载视频监控系统的设计方案;通过360度无死角四路鱼眼摄像头采集车身监控视频画面,实现多分割自由切换显示;阐述了视频监控系统的原理及软硬件模块的实现方法,重点讨论了视频分割、OSD显示模块的实现;最后,完成了整个系统的设计,并给出了实际运行结果。相比同类型的其他方案,成本下降了约三分之一。
According to the current situation and the market needs of the automotive electronics intelligent assistance system,a design scheme of four-road car video surveillance system was proposed based on muki-channel video decoder composite technology and OSD display technology.Multi-segmented freedom to switch the display was realized by four-road 360 degree fisheye camera to capture the surveillance video screen about car.This paper describes the principles of video surveillance system and the implementation of hardware and software modules.It focuses on the implementation of video segmentation,and OSD display module.Finally,this paper completes the design of the whole system and gives the actual operating results.The cost of the system decreased by about 1/3.
