| By analyzing the situations of the video inspecting system home and abroad, aimingat the demand of the broadcast center and the practical applications, this thesis talks abouthow we designed a system of video inspecting based on ARM. Comparing to traditionalmultimedia surveillance system, this scheme has the characteristics of small volume, lowcost, high stability and etc, therefore, it has good applied and development outlook. Thedesign of hardware system and the development of software system are mainly discussedin this thesis.With regards to the hardware design, the embedded video capture system is consist ofUSB camera and S3C2410 as its CPU, and as it connects to PC through Ethemet, thesystem of video inspecting can work well.As far as the software design, the system software and the internet applications mustbe designed. First we must port the BootLoader and embedded Linux kemel to the targetof ARM platform. Then, a system of video capturing and a video server based on TCPneed to be designed to run on the platform of ARM. In the end, we should design a TCPclient to get the compressed video data from the target of ARM platform, and then we candesign a program to decode the compressed video data and display on the screen to satisfythe needs of video inspecting.Finally, this thesis summarized the completed works, and the method of futureimproves has been given too. |
