Abstract


Put forward higher requirements for the rapid development of the public transport bus video surveillance systems , multi-function and intelligent design bus -car multi- channel monitoring system monitoring center , its multi- screen video streaming , storage and playback video files with Car terminal two-way communication , intelligent video analysis function , is of great significance . Bus multi-channel monitoring system of the research vehicle terminal is implemented by the DM365 DvR embedded system , transport protocol to use TcP as video data and control information , the design of this project monitoring center software use MFc programming . The main work is as follows : First , based on research and analysis of the functional structure of the bus multi-channel video surveillance system monitoring center focuses on the concrete implementation of the control software Pc - based monitoring center . Secondly, the monitoring center were studied Login car terminal , video streaming , decoding , display , control and other key technology research , including decoding part FFMpeg technology , part DirectDraw technology , network transmission part windows socket programming technology . To achieve the basic functions , such as multi-channel real-time monitoring of the monitoring center , multiple storage subtitle display to play H 2 64 video files , and control vehicle terminal . Addition, a vertical view of the number of statistical algorithms , the algorithm combines the human head detection and moving object tracking to count , including header information detected using the improved method for the detection of circular random Houh transform moving target tracking movement parameters match . Finally, the performance of the monitoring center software algorithms and statistics on the number of tests , experiments show that the monitoring center software decode and display better , people counting algorithm can more accurately the number of statistics in the video surveillance scenes .
