Abstract:Aiming at the current status quo that in industrial site, security monitoring field and automotive electronics industry camera acquisition′s environment building is complex, the cost is high,and the function is single,this paper designs and develops a network monitoring image processing platform based on HiSilicon chip. The platform is designed to use a combination of NVR and DVR, which can not only view, browse, play back, manage, and store multiple network camera video streams at the same time, but also perform image calculations, with the function of image/voice and dynamic frame control. The system adopts the design architecture of HiSilicon HI3559AV100+HI3531DV200 dual CPU, utilizes the excellent video processing capability of HI3559AV100, the excellent codec capability of HI3531DV200, the basic system of the system package CPU, the high-definition video interface circuit and the power supply circuit. The platform can receive video streams through the network, with a maximum decoding capacity of 16 channels of 1080p30, and supports 2 sets of high-definition heterologous outputs. The design has been verified by the actual engineering prototype, the image output is clear and smooth, and the system runs stably. It can be used to meet the application requirements of different scenarios, and also has the advantages of simple operation and wide applicability.

0 引言

随着社会经济的快速发展,数字图像处理的应用愈来愈广泛,现在在安防监控、工业现场、汽车电子等领域数字图像处理的要求进一步提升。图像处理系统一般由视频采集、视频处理、视频传输、视频显示、视频记录五部分组成[1]。目前主流的监控相机接口有SDI[2]、S-Video、MIPI、DVP、网口等,其中MPI与DVP不适合长距离传输应用场景;SDI是利用同轴电缆来传输非压缩的数字视频信号,S-Video是一种五芯接口,由两路视亮度信号、两路视频色度信号和一路公共屏蔽地线共五条芯线传输视频信号,这两种制式信号理论上可以长距离传输,但是线缆成本及长距离传输线缆上的损耗永远是个难以均衡的因素。至此网络摄像头就脱颖而出,可以长距离传输有能保障信号质量,对高视频分辨率的要求仅受限于网络传输带宽。通过高压缩率的编码技术,可以解决实现高分辨率全景视频的网络传输。其次现有的NVRDVR设备或图像处理系统,要么仅在编解码或处理方向功能出色,要么系统体积庞大、移动不便、安装困难[3]
