Abstract


The passenger automatic identification number has a very important practical value and broad prospects for development in the field of transport , shopping malls , and public safety . The passenger automatically identify the number of domestic research and it includes the video image collection, moving object detection , image processing , and many other , many of the core issues related to the field of image processing and recognition . In this thesis, the background to the National 863 Plan - \In this paper , based on the characteristics of railway passenger transport and technology trends , design of network -based streaming video image acquisition system so that the passenger number of automatic identification system can be remote real-time implementation without affecting the operation of other equipment of the image acquisition system . Part of the core algorithm of the number of automatic identification systems , innovative point of the paper , the paper has designed a number of optical flow field recognition model based background modeling . Use single Gaussian background modeling algorithm to extract the background , moving foreground background subtraction . Moving target detection and overlapping object segmentation algorithm using optical flow field . Finally, using image processing algorithms for optimization , and connected domain analysis of the statistics of passenger number . More traditional optical flow algorithm the number of iterations , the model to solve the problem of poor real-time , while ensuring high precision , high practicality . Finally, using C # and MATLAB mixed programming , railway passenger hub passenger number automatic identification system modules were developed initially realized the detection and automatic identification number of passenger railway passenger hub environment , and the results were analyzed , show that the system has high practicability .
