Reseach Of The Intelligent Video Monitoring System Based On DM6446

In recent years, with the improvement of quality of people’s living standards, the rapidadvances of computer technology, information and communication technology andmultimedia technology, the application of intelligent video surveillance system is used moreand more widely. However, most of these intelligent video monitoring systems are based onPC architecture, and have dispatched a complex monitoring scenes, high-cost, large-volumeand other characteristics. Moving object detection is not only a critical step in intelligentvideo monitoring system, but also a hot area of many academic researchers. In view of thissituation, this paper describes a intelligent video monitoring system base on DM6446whichcombines the technology of DaVinci that has high-speed image processing advantage,according to the study of analysis of the research on moving object detection. Moreover, it hascharacteristics of low-cost, high-intelligent, high-processing-speed and will be convenientlyapplied for various industries.This paper includes the following three main work:Firstly, research and improved moving object detection algorithm. Based on the researcha variety of moving target detection algorithm on related fields, in view of the externalenvironment, such as weather, temperature, illumination, changes in the backgroundsubtraction for moving object is mistakenly identified problems, and three-frame differencefor moving object undetected problem, was proposed the difference algorithm that integratethree-frame difference based on neighborhood and background subtraction method based onGaussian mixture model. The algorithm retains the advantages, and overcomes theshortcomings of single algorithm.Secondly, achieve these improved algorithms based on DM6446. Based on DM6446dual-core high-speed image processing hardware development platform, according to thealgorithm standard XDAIS-XDM design requirements, to create a functional improvement ofmoving object detection algorithm package, configure Codec Engine and Codec Server, thecreate function package for application layer calls.Finally, design to achieve the intelligent video monitoring system based on DM6446hardware platform. In the framework of the intelligent video monitoring system based onDM6446, combine with the improved algorithm analysis module, complete the design ofvideo sequence coding acquisition module, moving object detection module, decoding displaymodule underlying the camera area.The experimental results show that, based on DaVinci DM6446platform, software andhardware has good collaborative. The intelligent video monitoring system can better deal with the interference which was brought by the external environment change, successfully extractemoving object prospects, complete the object detection.
