Embodiment 1

[0032] see figure 1 , the present embodiment provides a demographic method based on face recognition technology, which includes the following steps:

[0033] S1. Setting at least one monitoring area;

[0034] Set up a monitoring area at the gate of the community or other key areas, and deploy monitoring cameras according to specific latitude and longitude.

[0035] S2. Obtain image data and location information of the monitoring area;

[0036] Obtain the image data of the monitoring area during the set time period. The image data can be captured by the monitoring camera or the screen captured in the video stream, and store the acquired image data and the location information of the monitoring area. At the same time, it can also be obtained and Store time data for easy subsequent queries.

[0037] S3. Obtain face recognition data in the image data;

[0038] Through the artificial intelligence algorithm, the image data is intelligently recognized, the face picture is extract...

Embodiment 2

[0048] On the basis of Embodiment 1, after step S5, it also includes counting the number of face recognition data acquisitions of at least two target persons in the monitoring area, and making an activity heat map of the person.

Embodiment 3

[0050] see figure 2 , this embodiment provides a population statistics system based on face recognition technology, which includes a data acquisition module, a face recognition data collection module, a data analysis module and a data storage module, and the above modules are connected through a network.

[0051] Wherein, the data acquisition module is used to acquire the monitoring image data of the monitoring area and the latitude and longitude position information of the monitoring area, the data acquisition module can be a monitoring camera, and is used to capture images or videos in the monitoring area in real time, each monitoring camera The configuration has latitude and longitude information.

[0052] The data analysis module is used to compare the acquired face recognition data with the face feature file data in the database, and count the number of successful comparisons.

[0053] The data storage module is used for storing the obtained image data, the extracted fa...

Abstract

The invention discloses a demographic method and system based on a face recognition technology. The method comprises the following steps: S1, setting at least one monitoring area; S2, acquiring imagedata and position information of a monitoring area; S3, acquiring face recognition data in the image data; S4, comparing the face recognition data with a preset regional personnel database; S5, afterthe comparison fails, storing the face recognition data into a dynamic personnel database; And S6, comparing the face recognition data obtained in the set time with a dynamic personnel database, counting the comparison success times of the target personnel, and storing the face recognition data in a regional personnel database when the comparison success times exceed a set threshold value. According to the method, through the face recognition technology and the big data real-time calculation technology, face images and face recognition feature data are extracted from a large number of monitoring cameras in real time, statistics and analysis are efficiently and accurately conducted on personnel in a specific area, the labor cost is saved, and the accuracy in the population statistics process is improved.

Description

technical field [0001] The invention belongs to the field of security technology and smart city technology, and relates to a method and system for analyzing personnel trajectory in a specific area, in particular to a population statistics method and system based on face recognition technology. Background technique [0002] With the development of our country's social economy, all kinds of economic activities are becoming more and more frequent, and the floating population is increasing rapidly. A large number of floating population has brought great pressure to government departments' household registration management, community personnel statistics and population monitoring, and criminal investigation and case detection. At present, the method of monitoring the population in a certain area is to check the video of each camera by the staff, judge and analyze with the naked eye to obtain the movement track of people or to count the population through door-to-door visits. This...
