[Abstract]:The problem of human flow statistics is a leading subject in the field of intelligent monitoring, which involves many disciplines and complex problems. Under intelligent video surveillance, the statistics of human flow can not only be used in commercial fields such as shopping malls and supermarkets, but also play an important role in security, traffic and so on. The human flow statistics system based on intelligent video surveillance is to use intelligent video surveillance technology to calculate the flow of people in the monitored area. The core technologies of the system include moving target detection, human body target recognition and tracking. In order to meet the demand of human flow statistics in open environment, this paper designs a human flow statistics system based on intelligent video surveillance, and analyzes and studies the key technologies. The main work is as follows: (1) after analyzing a variety of moving target detection algorithms, through the evaluation and comparison of the current mainstream background modeling algorithms, we determine the moving target detection algorithm based on ViBe. In view of the shortcomings of the traditional ViBe algorithm, an improved algorithm is proposed, which can effectively eliminate the ghost shadow and suppress the pixel noise of the flashing point in the aspect of human body target recognition and tracking by making a second classification of the foreground pixels. The HOG feature is used as the pedestrian description feature, and the HOG eigenvalue of the possible moving region is obtained by combining the improved ViBe algorithm, and then it is recognized by the pre-trained SVM classifier. In this paper, Cam-shift tracking algorithm is used to track human body target. Aiming at the unmatched phenomenon when the target is occluded, combined with the Kalman filter to predict the moving trajectory of the target, the research is based on the above key technology. Finally, the software and hardware platform of the system is designed, and the client interface is developed. After debugging and experiment, the system realizes the accurate statistics of the flow of people, and has good robustness.
