Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a monitoring method based on an MAC address provided in an embodiment of the present invention specifically includes the following steps:

s101: collecting a video of a monitored target place and an MAC address of intelligent equipment near the target place;

in this step, the video and the MAC address of the target site are acquired by the monitoring camera device and the WiFi probe of the target site, respectively.

The monitoring camera equipment has a real-time video recording function and can be a monitoring camera, a network camera, a human face camera and other equipment with real-time camera shooting and video transmission functions; the WiFi probe has the function of capturing the MAC address of the electronic equipment in real time; the monitoring camera equipment and the WiFi probe are integrally installed at the same position of a monitored target place, data acquisition is carried out on the passing people flow and the carrying equipment at the same time, and the effective range of the monitoring camera equipment or the effective range of the WiFi probe is determined near the target place. The monitoring camera equipment records video, time and equipment position information of the passing personnel, and the WiFi probe acquires MAC address information, time and equipment position information of the mobile equipment carried by the passing personnel. The monitoring camera device of the monitored target place at the same position and the device position information provided by the WiFi probe are the same.

It should be noted that, when a device sends information to another device through a wireless transmission technology, other similar devices around the device can receive the information, and the WiFi probe technology is based on this principle. Specifically, as long as a WiFi device is in the listening range of the WiFi probe, when the WiFi device (whether it is a terminal, a router, or other WiFi device) sends any Frame (Frame), regardless of the person to whom the Frame is sent, the probe can intercept and analyze some information of the MAC layer and the physical layer of the Frame, such as the MAC address of the sending and receiving device, the Frame type, the signal strength, and the like. The WiFi probe is transparent to surrounding WiFi devices. The WiFi probe does not require any interaction with surrounding equipment and does not itself need to emit any WiFi signal. The main purpose of the WiFi probe is to count and analyze surrounding WiFi devices. With the popularization of smart phones, WiFi probes are also deployed more and more. As long as the WiFi function of the handset is on, whether there is a connection hotspot or not, it can be detected by the probe.

S102: identifying a face image in the video, and searching a plurality of MAC addresses corresponding to the face image in a plurality of time periods;

in the step, a face image in the video is identified in an image identification mode, and a plurality of time periods of the identified face image appearing in the video are determined;

after the face image is determined, the time for acquiring the face image can be acquired. And searching the MAC address of the intelligent equipment detected by the WiFi probe at the time according to the acquisition time of the face image, wherein the intelligent equipment is considered as mobile equipment carried by the person with the face image. Therefore, at the acquisition time of the current face image, the face image exists corresponding to one, a plurality of or zero MAC addresses.

According to the collected face images, the MAC addresses of the intelligent equipment in each time period in the multiple time periods are determined when the same person appears in the target place in the collected video, and the multiple MAC addresses corresponding to the multiple time periods are obtained.

If the monitoring camera equipment adopts a face camera, a face image can be directly identified from the video.

S105: and iteratively filtering the multiple MAC addresses to obtain N MAC addresses corresponding to the face image, establishing association records of the face image and the N MAC addresses, and archiving the association records, wherein N is more than or equal to 1.

In the step, the face image and the MAC address corresponding to the face image are integrated into a correlation record, the face image of each person and the MAC address of the carrying equipment are correlated through the capturing time and the equipment position, and repeated and wrong correlation results are filtered and screened out continuously in an iterative mode.

As can be seen from the above description, according to the monitoring method based on the MAC address provided in the embodiment of the present invention, by acquiring the MAC address and the face image of the mobile device carried by the person, and performing association and screening between the MAC address and the face image, multi-dimensional information acquisition and multi-dimensional information interconnection and mutual inspection are achieved, more comprehensive and comprehensive personnel deployment and control are achieved, and the success rate of positioning key personnel is improved.

The embodiment of the invention provides a monitoring method based on an MAC address. Referring to fig. 2, before the step S105, the method further includes the following steps:

s103: comparing the identified face image with face pictures in a face picture library and determining personnel number information of the face image;

in this step, the identified face image and the corresponding multiple MAC addresses are created to generate a face picture library, and data can be stored and utilized according to the face picture library. When a face image is newly acquired, comparing the identified face image with face images in a face image library, and determining personnel number information of the face image; the face image collected in real time is stored.

In order to avoid excessive repeated data, the identified face image is compared with the face image in the face image library, if the face image is successfully compared with the face image, the face image is stored in the image library, and the person number information corresponding to the face image in the face image library is given to the face image; if the comparison between the face image and the face image is unsuccessful, the face image is not stored in the face image library, a new personnel number is added in the face image library, and the new personnel number is given to the face image.

S104: and establishing the face image, the capturing time of the face image, the capturing position of the face image and the personnel number information as a face record.

In this step, the person number information is used as a sequence, and the facial image and the capture position of the facial image with the same capture time are filled in each sequence.

As can be seen from the foregoing description, the embodiment of the present invention provides a monitoring method based on an MAC address, which can generate a basic human face picture library, store and use data, and reduce redundancy of the human face picture library.

In an alternative embodiment, a specific implementation of step S105 is provided. Referring to fig. 3, the step S105 specifically includes the following steps:

s1051: acquiring the MAC address of the intelligent device corresponding to the face image in each time period in a plurality of time periods, and classifying the same MAC address in the acquired MAC addresses into one class;

in this step, a time segment of a face image is extracted from a plurality of time segments with face images extracted from a video, and the acquisition time T of the face image and the position information of the device are found. And searching the record of the MAC address at the same acquisition time T to obtain the specific information of the MAC address corresponding to the face image in the time period. And planning the same MAC address in the obtained MAC address information into a class, wherein the same MAC address is a mobile device, and the number of the classes is the number of the mobile devices. And determining the mobile equipment carried by the person corresponding to the face image from the number of the mobile equipment.

The multiple time periods correspond to multiple MAC addresses, and the same MAC addresses in the multiple MAC addresses are classified into one class.

S1052: determining the MAC address with the acquisition time of the MAC address in each type of MAC address closest to the capture time of the face image;

in this step, a plurality of MAC addresses corresponding to a plurality of time periods are preliminarily filtered: and for each type of MAC address in each time period, only one MAC address with the acquisition time of the MAC address closest to the capturing time of the face image in each type of MAC address is reserved, and the records of the rest MAC addresses are deleted.

S1053: counting the nearest MAC address in each time period in a plurality of time periods, and determining N MAC addresses with the occurrence frequency exceeding a preset threshold in the plurality of time periods;

and the N MAC addresses are N MAC addresses corresponding to the face image.

In this step, the MAC address in the MAC address record after the preliminary filtering is associated with the face image by the preliminary filtering. Wherein, a preliminary personnel association record library can be formed through preliminary filtering. Each preliminary personnel association record contains personnel number information, face information, time information, equipment position information and MAC address information.

Counting the nearest MAC address in each time period in a plurality of time periods, and determining N MAC addresses with the occurrence frequency exceeding a preset threshold in the plurality of time periods;

determining that the matching between the personnel corresponding to the face image and the equipment corresponding to the N MAC addresses is successful, extracting and filing all preliminary personnel association records containing the N MAC address information into another personnel matching record base, and simultaneously, recombining the MAC address information, the personnel number information and the face information into a personnel information record and filing the personnel information record into a personnel information base; otherwise, if the occurrence frequency does not exceed the threshold value, the matching is considered to be failed, and other operations are not carried out.

Furthermore, information correlation searching can be carried out, and mutual searching is carried out in a personnel information base through personnel number information, human face information and MAC address information; the time and the place of the personnel are positioned by searching the record of the same personnel number in the personnel matching record library, and the action track is drawn; and (4) giving a new MAC address by the user, and searching corresponding face information in the personnel information base.

From the above description, the iterative filtering method provided by the invention can simply and quickly determine the mobile device carried by the person corresponding to the face image.

In order to further explain the method of the present invention in detail, the present invention provides a specific application example of a monitoring method based on MAC address, which includes the following specific contents:

the monitoring camera equipment and the WiFi probe are integrally installed at the same position of a community gate, the monitoring camera equipment and the WiFi probe can be installed in a plurality of communities, and the communities can have a plurality of gates. The monitoring camera equipment collects face videos and corresponding time and positions of people who enter and exit the community, and meanwhile the WiFi probe collects MAC addresses and corresponding time and positions of mobile equipment (mainly a mobile phone) carried by people who enter and exit the community. The monitoring camera equipment collects face videos, and if the monitoring camera equipment directly adopts a face camera, face pictures can be directly identified. The face analysis server identifies the face image in the video recording, and then performs face comparison analysis with the face image in the face image library (as shown in table 1).

Table 1: face gallery

If the comparison is successful, giving the same personnel number information as the human face picture in the human face picture library; and if the comparison fails, adding a new personnel number in the face image library, and associating and archiving the acquired face information and the personnel number. And storing each piece of face information, the face capturing time, the equipment position information and the personnel number information as a piece of face record (shown in a table 2).

				1	T1	X1	1.jpg
1	T2	X1	1.jpg
				1	T3	X3	1.jpg
2	T2	X2	2.jpg
				2	T3	X3	2.jpg
3	T4	X3	3.jpg

The WiFi probe analysis server stores each captured MAC address information and time and device location information as a MAC record (see table 3). And the face analysis server and the probe analysis server respectively send the sorted records to the data analysis server through a network.

Time of day	Position of	MAC address
			T1	X1	M1
T2	X1	M1
			T3	X3	M1
T2	X2	M2
			T3	X3	M3
T4	X3	M4

And the data analysis server arranges the face record and the MAC record by using a data analysis algorithm. First, a preliminary personal association record is obtained through preliminary filtering (see table 4).

2	T2	X2	2.jpg	M2
					2	T3	X3	2.jpg	M3
3	T4	X3	3.jpg	M4

And performing iterative filtering on the preliminary personnel association records, finding all the preliminary personnel association records with the same personnel number, classifying the preliminary personnel association records into one class, and counting the MAC address information in the preliminary personnel association records. Referring to table 3, for person No. 1, there are 3 records and the same MAC address (M1) appears 3 times; for person 2, there are 2 records, but the MAC addresses are not the same 2 times; for person No. 3, there is only one record. A matching threshold value of 2 (which can be changed according to actual conditions) is agreed in advance, that is, if the number of times of the same MAC address appearing exceeds 2 times (more than or equal to 3 times) for the same person number, the matching is considered to be successful. Accordingly, only person number 1 matches successfully, and both person numbers 2 and 3 fail. Therefore, the records associated with person number 1 are stored in the person matching records repository (see Table 5).

Further, when performing association search, the user can perform information association search: the method comprises the following steps of mutually checking in a personnel information base through personnel number information, face information and MAC address information; the time and the place of the personnel are positioned by searching the record of the same personnel number in the personnel matching record library, and the action track is drawn; a user newly gives an MAC address, and searches corresponding face information in a personnel information base, which comprises the following specific steps:

(a) and the personnel information base is mutually checked through personnel number information, face information and MAC address information.

(b) And (4) searching records of the same personnel number in a personnel matching record library, locating the time and place of the personnel and describing the action track. As for person No. 1, its occurrence in a series of time locations is found in table 5: (T1, X1) (T2, X1) (T3, X3). The action track of the person No. 1 in the cell can be described by positioning on the map.

(c) And (3) giving a new MAC address (newly acquired by front-end equipment or released to a data analysis server by a user) by the user, and searching corresponding face information in a personnel information base. For example, a criminal makes a crime in a certain place, only the MAC address of the device carried by the person is collected, and no face information is collected. If the person passes through information acquisition before, the information is recorded in the database, so that the face information corresponding to the MAC address can be searched in the person information database, and then criminals can be arrested through face arrangement control.

From the above description, it can be known that, through collecting the mobile device MAC address and the face image carried by the person, and performing association and screening of the MAC address and the face image, multi-dimensional information collection and multi-dimensional information interconnection and mutual check are realized, more comprehensive and comprehensive person information search and multi-dimensional control are realized, and the success rate of key person positioning is improved.
