S102, the monitoring platform acquires a target camera through a positioning system, the target camera is used for shooting the position of the mobile terminal, and the position information of the mobile terminal is acquired from a mobile communication network by the positioning system.
In the embodiment of the present application, a camera that shoots a position of a mobile terminal is referred to as a target camera, and for example, a monitoring platform may obtain the target camera through the following several ways:
the method comprises the steps that a monitoring platform obtains position information of a mobile terminal from a positioning system, and determines a target camera according to the position information of the mobile terminal and information of a plurality of locally stored cameras, wherein the distance between the target camera and the mobile terminal is smaller than a preset distance, and the information of the plurality of cameras comprises information and position information of a shooting range of the cameras.

The first request message and the first response message may be newly defined messages or may multiplex existing messages.
In this embodiment, the position information of the camera may be longitude and latitude of the position of the camera, or may also be longitude, latitude and height information of the position of the camera, and the height information may be altitude or floor information. In general, when a camera is installed outdoors, the position information of the camera is longitude and latitude, and when the camera is installed indoors, the position information of the camera includes longitude, latitude, and altitude information.
Alternatively, when the cameras are installed indoors, the position information of the cameras includes not only absolute coordinates (including longitude, latitude, and altitude information) but also relative coordinates, and the position of each camera may be expressed using the relative coordinates with a certain reference point of the building as a unified reference point.
It is understood that the position information of the base station and the position information of the mobile terminal referred to in the present application can be represented by a representation method of the position information of the camera.

Optionally, the monitoring platform may also determine a target sector corresponding to the mobile terminal according to the location information of the mobile terminal, and determine an adjacent sector of the target sector, where the target sector is a currently accessed sector of the mobile terminal or a previously accessed sector. And calculating the distance between the mobile terminal and the camera corresponding to the target sector and the distance between the mobile terminal and the camera corresponding to the adjacent sector of the target sector, and then selecting the camera of which the distance between the mobile terminal and the camera is less than the preset distance as the target camera.
The method does not need to calculate the distance between the mobile terminal and each camera, only needs to calculate the distance between the mobile terminal and the camera corresponding to the target sector and the distance between the mobile terminal and the camera corresponding to the adjacent sector of the target sector, and reduces the calculation amount of the monitoring platform.
Optionally, the monitoring platform may also use a camera with the smallest distance to the mobile terminal as the target camera, which is not limited in this embodiment.
Optionally, the monitoring platform stores a corresponding relationship between a plurality of cameras and a sector, wherein a shooting range of the camera having the corresponding relationship overlaps with a coverage range of the sector. The camera and the base station are deployed cooperatively, so that the camera can accurately shoot the position of the mobile terminal. The larger the overlapping area of the shooting range of the camera and the coverage range of the sector is, the more accurate the shooting of the camera is.
And secondly, the monitoring platform acquires information of a target sector corresponding to the mobile terminal from the positioning system, and the monitoring platform determines that a camera corresponding to the target sector is a target camera according to the target sector and a corresponding relation between the locally stored camera and the sector, wherein the target sector is a currently accessed sector or a previously accessed sector of the mobile terminal, and the shooting range of the camera with the corresponding relation is overlapped with the coverage range of the sector.

And thirdly, the monitoring platform sends a first request message to the positioning system, wherein the first request message is used for requesting the target camera and comprises the information of the mobile terminal. And the monitoring platform receives a first response message returned by the positioning system, wherein the first response message comprises the information of the target mobile terminal.

In this embodiment, the monitoring platform determines the target camera by using the position information of the mobile terminal acquired by the positioning system from the mobile communication network, and uses the target camera to follow the position of the mobile terminal, so that the monitoring platform can be applied to outdoor scenes and indoor positioning, and particularly can realize positioning in multi-storey buildings.
In an indoor scene, due to the cooperative deployment of the base station and the camera, the monitoring platform can still acquire the position information of the mobile terminal, is not limited by whether the target object can provide the GPS data of the carried mobile terminal or not, and can continuously track the target object.
In addition, the GPS data of the mobile terminal needs to be authorized by the user for use, so that the monitoring platform cannot acquire the GPS data of the mobile terminal in many cases, which results in that the target object cannot be tracked. According to the method, the positioning system obtains the position information of the mobile terminal from the mobile communication network, and the target object is not perceived, so that the monitoring method is more widely applied.
