Motion Detection System Based On DM6446

With fast development of digitization and network technology, the development ofmonitoring technique is undergoing great changes.Especially intelligent videomonitoring technology on behalf of latest technology of video surveillance hasbecome hot spot.With different from the image acquisition, transmission and storage ofconventional monitoring system,intelligent video monitoring technology can detect andidentify different objects based on image acquisition encoding, and find abnormalsituation in the monitored region, then immediately reflect to achieve alert.Comparedwith the shortcoming of traditional monitoring system, intelligent video monitoringtechnology has a huge advantage. With further maturity and improvement of technology,intelligent video monitoring technology has been widely used in such important fieldsas safeguarding, transportation, military affairs and business.Moving object detection is the important part of the intelligent monitoring study. Inthis paper, it makes related research on the aspect of moving object detection. First of all,it introduces preprocessing algorithm,which is used to deal with original image. Then itmakes in-depth study and discussion on moving object detection algorithm. Finally,combination with the characteristics of DM6446embedded platform, it brings movingobject detection algorithm under this embedded platform. The introduced algorithmadopts the way of combination of background difference method and inter-framedifference method to make pretreatment,phase arithmetic and Binarization processingunder the condition of Guassian model statistical theory.This article chooses DM6446as development platform, system achieves thegathering,playing and moving object detection for video signal.Establishment ofexperimental environment tests and verifies the algorithm used in this article. Theexperiment results show that, based on high-end DM6446platform, software andhardware runs well,which can meet the requirement of real-time collection and imageprocessing under the conditions of insensitive illumination and alteration of backgroundcontent.
