Embodiment 1

[0027] A target person tracking method that combines mobile network records and video surveillance data, such as figure 1 As shown, it includes the following five main steps:

[0028] S1. Find the monitoring area and the corresponding monitoring time period that the target person passes through from the video surveillance video data;

[0029] S2. For each monitoring area where the target person appears, search the cell phone base station information covering the area in the set of mobile communication network base stations;

[0030] S3, for each mobile phone base station found in step S2, obtain all target mobile phone track data sets that are in the vicinity of the base station within the monitoring time period described in step S1;

[0031] S4, seeking the intersection of the target mobile phone trajectory data sets obtained according to each base station in step S3, obtaining the target mobile phone trajectory data set;

[0032] S5. Extract the target mobile phone number ...

Embodiment 2

[0043] This embodiment is the same as Embodiment 1 except the following:

[0044] When the number of mobile phones returned by the intersection of the target mobile phone trajectory data sets acquired by each base station in the step S4 is greater than 1, this embodiment is implemented through the following process, and finally locks the mobile phone number of the target person.

[0045] Step A1, when the number of mobile phones returned by the intersection of the target mobile phone trajectory data sets acquired by each base station in the step S4 is greater than 1, it is necessary to track multiple target mobile phones determined after the intersection. According to the location of the target mobile phone, the video camera recording in the area is dispatched.

[0046] Step A2, if the target person is found in a certain camera, then execute the steps S2, S3 and S4 again to obtain the intersection of the acquired target mobile phone trajectory data sets, and obtain the target ...

Abstract

The invention relates to the field of mobile communication network and video monitoring, and discloses a target person tracking method combining mobile communication recording and video monitoring data. The method comprises the steps that S1, monitor areas passed by a target person and a corresponding monitor period are found from video monitoring recording data; S2, information of mobile phone base stations which cover the monitor areas is found from a mobile communication network base station set; S3, all mobile phone historical trajectory data sets passing the base stations in the monitor period are acquired; S4, the intersection of mobile phone trajectories extracted from the base stations is acquired, so as to acquire the trajectory data set of a target mobile phone; and S5, a mobile phone number with a centralized target mobile phone trajectory is extracted, and the target mobile phone is identified and tracked according to the mobile phone number in a mobile network. Even if the target person no longer appears in a monitoring video, ongoing tracking still can be carried out.

Description

technical field [0001] The invention relates to a target person tracking technology, in particular to a target person tracking method combined with mobile network records and video surveillance data. Background technique [0002] Today, video surveillance technology has been widely used in major cities across the country, playing an important role in ensuring the personal safety of citizens. In the traditional security incident processing method based on surveillance video, the investigators manually search and compare the video recordings captured by the camera, which is inefficient and prone to omissions. With the development of image recognition technology, the intelligent video surveillance system with person recognition function has been widely used. Based on image recognition technology, this type of system automatically analyzes the acquired video images to realize functions such as target person identification, tracking, and behavior trajectory analysis.
