Research On Panoramic Dual Camera Monitoring System Based On Embedded System

With the rapid development of network and the popularization of wireless network,more and more wireless products come out,and the application of wireless video monitoring in family life is more and more extensive.With the improvement of image processing ability and processor computing ability,the requirements of clarity,dynamic tracking,mobile alarm and other aspects of video monitoring are also put forward.Based on the analysis of daily life needs,a full view dual camera video monitoring system based on Embedded Linux is designed.Through consulting the literature of intelligent monitoring system at home and abroad,this paper analyzes the panoramic monitoring system in the domestic market,and proposes a panoramic dual camera monitoring system based on Embedded Linux.This paper analyzes the commonly used video monitoring system,establishes a whole embedded design scheme,with the intelligent m3c processor and Pisces eye lens as the main components,introduces the embedded related technologies:embedded technology,WiFi transmission technology,video transmission protocol,etc.This paper introduces image preprocessing,studies three classical moving target detection algorithms and makes a brief analysis.Finally,vibe algorithm is selected as the moving target detection algorithm of the monitoring system.The concept and basic principle of vibe algorithm are studied.Vibe algorithm includes background model construction and initialization,vibe dynamic detection method,background model update strategy,etc.the source code of vibe algorithm is completed and the result graph of moving object detection is debugged.This monitoring system takes the intelligent m3c core processor as the core,integrates the fish eye dual lens,gravity sensor,audio module and other devices of fortco,and constructs an embedded software platform including porting bootloader,cutting kernel and compiling root file system.Finally,based on the in-depth study of the v412 video driver framework,alsa audio framework,multithreading and the entire video acquisition process,the video acquisition module,video playback,audio driver,communication code writing of socket,source code modification of SD card driver and image splicing algorithm are completed.Through the overall test of the whole video monitoring system,after adjustment and improvement,it can meet the design requirements and achieve the expected goal.This monitoring system adopts WiFi mode transmission,easy installation,wide monitoring range,real-time high-definition panoramic picture and other advantages,and has good application prospects and certain promotion value.
