Description
Technical field
The present invention relates to security monitoring and image processing and analysis technical field, more particularly to it is a kind of based on the public of face
Place people flow rate statistical method and system.
Background technology
As the continuous progress of society, the application range of video monitoring system are more and more wider.Entrance in many places
Monitor camera often is installed, gradually realizes the intellectual analysis based on video.In intelligent analysis system, people flow rate statistical is this
One critical function of system, it can be efficiently applied to market, bus, airport entrance, subway station entrance, exhibition venue
The people flow rate statistical of the public places such as entrance, by being collected to different zones and different periods flow of the people data, excavating,
Contrast and analysis, important evidence is provided for user management and decision-making.
In existing video monitoring, people flow rate statistical is mainly manually checked to realize by monitoring personnel.It is this artificial
The method for counting flow of the people is reliable in the case where monitoring period is short, flow of the people is sparse, but due to human eye biological nature
Limitation, when monitoring period is longer, when flow of the people is intensive, statistical accuracy will be greatly reduced, and the mode manually counted needs
Expend substantial amounts of human cost.People flow rate statistical method based on video analysis can realize the programming count of flow of the people, solution
Certainly manually count the various problems brought.At present, the flow statistical method based on video analysis mainly has three classes：
First, the method for distinguished point based tracking, this method tracks some motion characteristics points first, then to characteristic point
Track carry out cluster analysis, so as to obtain flow of the people information；The method of distinguished point based tracking needs to track some movements
Characteristic point, then carries out cluster analysis to the track of characteristic point, so as to obtain flow of the people information, the shortcomings that this method is characteristic point
Itself it is difficult to stably track, counting precision is poor.
Second, the method based on human body segmentation and tracking, this method is firstly the need of moving target block is extracted, then to fortune
Moving-target block is split to obtain single human body target, finally tracks the statistics that each human body target realizes flow of the people；Based on people
Body is split and the method for tracking is firstly the need of moving target block at extraction, then moving target block is split to obtain single people
Body target, finally tracking obtains the track of each human body, so as to fulfill the statistics of flow of the people.The shortcomings that this method is when human body is deposited
When blocking, the accuracy of human body segmentation is difficult to be guaranteed, and influences statistical accuracy.
Third, the method based on the number of people or head and shoulder detect and track, this method detect the number of people or head and shoulder, pass through in video
Tracking to the number of people or head and shoulder carries out the statistics of flow of the people.Method based on number of people detect and track is to detect people in video
Head, the statistics of flow of the people is carried out by the tracking to the number of people, when camera angle is suitable, the number of people occur situation about blocking compared with
It is few, therefore two methods accuracy increases the method based on number of people detection earlier above, has company to propose based on the number of people at present
The method of detection statistics number, such as Beijing Z-Star Microelectronics are previously mentioned in the patent document of application number 200910076256.X
In method, sport foreground is extracted first, is then searched in the foreground using the grader of haar features training dual serial predetermined
The number of people of size, realizes that the number of people detects, wherein, haar features, are a kind of rectangular characteristics, size and combination by varying rectangle
Mode can describe the shape and half-tone information of target.The grader that this method uses simply detects same class target, Wu Fatong
When detect inhomogeneity target, for example, the number of people of dark hair (including wearing dark cap) and light hair (bag can not be detected at the same time
Include and wear light cap) the number of people, cause the number of people statistics it is not comprehensive.
Other people current existing flow statistical methods have：The one kind that discloses of Application No. 200810037799 is based on intelligence
Can video identification technology people flow rate statistical method and system, its information scanning in standardized human body's template database obtains
Body templates in current frame video image, then judges two preceding line directions of body templates, and then counts two
Flow of the people on direction.The patent of Application No. 201010155338 discloses a kind of pedestrian's flow based on traffic monitoring facilities
Statistical method and system, it carries out number of people detection according to standard number of people template in detection block, judges whether is the number of people that detects
Detection line is pressed, so that it is determined that effective number of people number in detection block.Then matched with previous testing result, and according to
The number of people in different motion direction is counted with result.Finally according to the facilities of detection block and detection line, flow is carried out
Statistics.
