Abstract

The invention discloses a human flow counting method based on a video analysis technology, and relates to an intelligent video analysis technology. The counting method comprises the following steps of: (1) training a human head feature model; (2) acquiring a foreground point of a moving object by using an inter-frame difference; (3) performing human head feature extraction and identification; (4) performing human body local feature identification; (5) performing human head feature region tracking; and (6) performing human flow counting. The performance is stable, speed and efficiency are high, and the false alarm rate is low; and generality, portability and extensibility are high, and the method is suitable for equipment of various manufacturers and various intelligent video analysis systems.

Description

technical field [0001] The invention relates to a video intelligent analysis technology, in particular to a human traffic statistics method based on the video analysis technology. Background technique [0002] In the video intelligent analysis system, people flow statistics is an important function of the system. It can be effectively applied to people flow statistics in public places such as shopping malls, buses, airport entrances and exits, subway station entrances and exits, and exhibition venue entrances and exits. Summarize, mine, compare and analyze the traffic data of different time periods to provide an important basis for user management and decision-making. [0003] At present, the existing people flow statistics methods are mainly: [0004] 1.
