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.

隨著社會經(jīng)濟(jì)的快速發(fā)展,數(shù)字圖像處理的應(yīng)用愈來愈廣泛,現(xiàn)在在安防監(jiān)控、工業(yè)現(xiàn)場、汽車電子等領(lǐng)域數(shù)字圖像處理的要求進(jìn)一步提升。圖像處理系統(tǒng)一般由視頻采集、視頻處理、視頻傳輸、視頻顯示、視頻記錄五部分組成[1]。目前主流的監(jiān)控相機(jī)接口有SDI[2]、S-Video、MIPI、DVP、網(wǎng)口等,其中MPI與DVP不適合長距離傳輸應(yīng)用場景;SDI是利用同軸電纜來傳輸非壓縮的數(shù)字視頻信號,S-Video是一種五芯接口,由兩路視亮度信號、兩路視頻色度信號和一路公共屏蔽地線共五條芯線傳輸視頻信號,這兩種制式信號理論上可以長距離傳輸,但是線纜成本及長距離傳輸線纜上的損耗永遠(yuǎn)是個難以均衡的因素。至此網(wǎng)絡(luò)攝像頭就脫穎而出,可以長距離傳輸有能保障信號質(zhì)量,對高視頻分辨率的要求僅受限于網(wǎng)絡(luò)傳輸帶寬。通過高壓縮率的編碼技術(shù),可以解決實現(xiàn)高分辨率全景視頻的網(wǎng)絡(luò)傳輸。其次現(xiàn)有的NVR、DVR設(shè)備或圖像處理系統(tǒng),要么僅在編解碼或處理方向功能出色,要么系統(tǒng)體積龐大、移動不便、安裝困難[3]。
