Design And Implementation Of HD Video Surveillance System Based On DM368

With the pursuit of high-definition, networked, intelligent video surveillance system,this thesis designs a high-definition video surveillance system based on DM368processor bymeans of the powerful TI DaVinci technology.Firstly, the video surveillance system which mainly related to the embeddedLinux operating system, the basic principle and method of the video compression and videocodec standard, Ethernet and stream media technology is analyzed briefly, to make theoreticalpreparation for the further system development. Secondly, in the hardware design of thesystem, this thesis makes a detailed analysis about the ARM subsystem,video co-processor,video processing subsystem and peripheral interfaces based on the DM368hardware platform,designs the peripheral hardware devices according to the need of surveillance system, andpresents video input and output interface modules, external memory interface module,Ethernet communication module design principle, power modules in detail which the systemrequired meets the need of the system hardware. Besides, the system software developmentplatform is built, mainly about the Linux operating system’s software developmentenvironment, including the development of Bootloader and the cutting and grafting of systemkernel. Finally, the system application software which including video capture, videoencoding and Ethernet transmission is designed that ensures the surveillance systems canreal-time capture, compress and transmit the high-definition video.In this thesis, the design of high-definition video surveillance system meets the demandof general video monitoring, has certain versatility and practicability.This system has certainimprovement compared with the existing monitoring system products, and possesses somereference value and economic value.
