Specifically, after the cloud platform obtains the video and the image, the video and the image can be compared, so that the specific position of the target terminal is determined. If the face can be extracted from the image, the face can be identified by using a face identification algorithm, so that the person to be tracked is determined to track the target terminal. Of course, after the network Camera (IP Camera, IPC) obtains the video and the image, the video and the image may also be compared according to the above procedure, so as to determine the person to be tracked, so as to track the target terminal.

Wherein, the terminal information includes: the identification information of the terminal and the status flag category of whether the terminal is blocked. The identification information of the terminal includes: the factory serial number, the MAC address, the push ID, etc. of the terminal, if the terminal is a mobile phone, the identification information of the terminal may also be a mobile phone number, etc. The status flag type of whether the terminal is blocked can be represented by a flag bit, and a flag bit user can define the status flag type by himself, for example: "0" indicates not occluded and "1" indicates occluded; alternatively, "none" means not occluded and "have" means occluded.
In a specific embodiment, before sending the probe information to the target terminal, the method further includes: judging whether personnel appear in the coverage area of the network camera; if yes, the step of sending the detection information to the target terminal is executed. Wherein, judge whether personnel appear in the network camera coverage, include: starting a face recognition function, and if the face is recognized, determining that personnel appear in the coverage area of the network camera; otherwise, determining that no personnel are present in the coverage area of the network camera. When no personnel appear in the coverage area of the network camera, the current tracking flow can be ended; or the network camera broadcasts the detection information and collects the response of the detection information within a preset time period, if the response is collected, the network camera acquires the information of the terminal which sends the response and executes S202-S203; if no response is collected, ending the current tracking flow. The network camera sends or broadcasts the detection information by utilizing the self Wifi function or the Bluetooth function.
S202, sending terminal information to a cloud platform so that the cloud platform can judge whether to track a target terminal according to the terminal information; if so, a tracking instruction is sent to the target terminal so that the monitoring application program in the target terminal controls the target terminal to execute the target operation.
The number of the target terminals may be plural or one. Therefore, the number of terminal information sent to the cloud platform may be multiple or one, and the cloud platform needs to judge one by one according to the multiple terminal information.
In this embodiment, the target operation includes capturing an image or turning on a light source, and the two may alternatively be performed. The tracking information may also be sent to a mailbox or the like bound by the tracked terminal. The user may bind the mailbox for the terminal on the cloud platform for tracking use.
In one embodiment, a monitoring application in a target terminal controls the target terminal to execute a target operation, including: if the target terminal is determined not to be blocked according to the state mark type in the terminal information, a monitoring application program in the target terminal controls a front camera and/or a rear camera of the target terminal to shoot an image, and the image is sent to a network camera; correspondingly, recording and sending tracking information to the cloud platform, including: and sending the video obtained by the image and the real-time video to a cloud platform.

Wherein the light source is a flash lamp or an infrared emitter. The infrared emitter may be a stand-alone device or may be a device in other sensors, such as an infrared emitter in an infrared ranging sensor.
When the target terminal starts the infrared light source, the network camera is switched to a night vision mode to record video in real time. The infrared light source can be seen in the night vision mode, so that when a case transacting person views a video, the person with the target terminal can be quickly found, the related person is locked, and the tracking success rate is improved.
S203, recording and sending tracking information to the cloud platform in the process of executing target operation by the target terminal.
In a specific embodiment, the cloud platform determines whether to track the target terminal according to the terminal information, including: the cloud platform extracts the identification information of the target terminal from the terminal information and inquires whether the identification information is marked as to-be-tracked; if yes, tracking the target terminal; if not, the target terminal is not tracked.
The network cameras are preset at various positions of the monitored area, and the setting positions of the network cameras are recorded in the cloud platform. When the user loses the terminal, the position and time of the terminal loss can be recorded in the cloud platform in time, and the terminal is marked as to-be-tracked. The cloud platform can determine which network camera covers the lost position of the terminal, so that an activation instruction can be timely generated, and the network camera can help to track the lost terminal. The network camera always records the real-time video of the coverage range of the network camera.
Therefore, in the embodiment of the application, the target does not need to send information at any time, only needs to execute the target operation under the control of the monitoring application program, and the network camera records and sends the tracking information to the cloud platform in the process of executing the target operation, so that the collection and recording of the tracking information are completed. The whole process target does not need to work all the time, so that the online time of the target can be prolonged, the effective collection of tracking information is realized, and the tracking success rate is improved.
The embodiment of the application discloses a second target tracking method, which relates to a cloud platform, a plurality of network cameras, a monitoring APP (i.e. the monitoring application program mentioned above) registered in the cloud platform and a client for viewing a monitoring video. Referring to fig. 3 for the relationship among the cloud platform, the network camera and the client, the network camera is responsible for the acquisition, data packaging and uploading of the front-end video. The cloud platform is responsible for storage of video resources, storage of a cloud account system, storage of client side configuration information and the like. The clients generally comprise a mobile client and a PC client, and can receive alarms for users to watch live videos and the like.
Assuming that the tracked terminal is a mobile phone, installing a monitoring APP on the mobile phone, and performing the following settings:
1) Opening a monitoring APP, registering and logging in a cloud platform;
2) Opening a trackable switch in the monitoring APP, which means: allowing the monitoring APP to collect the identification information of the current mobile phone number, serial number, MAC address, push ID and the like, wherein the identification information is shown in Table 1. If the acquisition is not acquired, the acquisition is set to be empty.
TABLE 1
| Information encoding | Terminal identification information |
| 1 | Mobile phone number |
| 2 | Sequence number |
| 3 | MAC address |
| 4 | Push ID |
3) The method comprises the steps that a mailbox is bound and tracked for a current mobile phone in a monitoring APP, so that the monitoring APP reports terminal identification information, mailbox information and a registered cloud account to a cloud platform for storage by the cloud platform.
4) The setting monitoring APP is always operated when the mobile phone is in standby.
When the mobile phone of the user is stolen or lost, the user can log in the cloud account at other terminals (mobile phone and PC) in time, and the state of the terminal is set to be 'to be tracked', so that the mobile phone is stolen or lost, and meanwhile, the place and time of the mobile phone being stolen or lost are reported. After the tracking process is completed, but the terminal has not successfully found, the state of the terminal is set as 'tracking completed'. And when the mobile phone is not stolen or lost or successfully retrieved, the state of the terminal in the cloud platform is normal.
The mobile phone status recorded in the cloud platform can be seen in table 2.
TABLE 2
When the cloud platform detects that the state of the terminal is set to be 'to be tracked', the network camera receiving the activation instruction is determined according to the position reported by the user, and the activation instruction is sent to the network camera, so that the network camera enters the 'mobile phone tracking' state. The sites reported by the user can be multiple, so the network cameras receiving the activation instructions can be multiple.
The network camera (IPC) receiving the activation instruction enters a state of tracking the mobile phone, namely, after the stolen system is activated, the process shown in fig. 4 is executed, which is specifically as follows:
1) The IPC starts a face detection function, and when the face is identified, the IPC starts a Wifi detection function, namely, detection information is sent through a wireless broadcasting technology.
2) And when the monitoring APP installed on the mobile phone in the IPC coverage area receives the detection information, the terminal identification information and the flag bit of whether the terminal is installed in the pocket or not listed in the table 1 are sent to the IPC.
Wherein, whether the terminal is arranged in the pocket can be judged by utilizing a light sensor and a distance sensor in the terminal. Such as: the light brightness value of the environment where the terminal is located is smaller than a certain value, and meanwhile, the distance between the terminal and surrounding objects is smaller than a certain value, so that the terminal is determined to be arranged in a pocket; otherwise, it is determined that the terminal is not held in the pocket.
3) After the IPC receives the information, the information is reported to the cloud platform so that the cloud platform can inquire the stolen mobile phone, and the inquired result is returned to the monitoring APP.
4) Monitoring APP judges the query result: if the mobile phone is a stolen mobile phone, the monitoring APP enters a stolen state, and the following operations are executed according to whether the terminal is in a pocket or not:
a. when the mobile phone is not in the pocket, the front camera and/or the rear camera are used for capturing pictures at fixed time and sending the pictures to the IPC so that the IPC can be sent to a mailbox or a cloud platform; and the mobile phone and the IPC are not transmitted any more until the communication is interrupted.
b. When the mobile phone is in the pocket, the monitoring APP triggers the mobile phone to enable the flashlight or the infrared emitter in the mobile phone to flash the light source so that the IPC can record a flash picture until the communication between the mobile phone and the IPC is interrupted, and the mobile phone does not flash. Wherein the scintillation light source is preferably an infrared light source.
When the mobile phone is confirmed to be in a stolen state and the mobile phone is in a pocket, the IPC is set to be in a night vision mode in order to better detect infrared light emitted by the mobile phone. In the night vision mode, the infrared filter of the lens is closed, so that objects with high infrared light intensity can be more obviously seen.
When the mobile phone is in the pocket, the relevant video is checked, and a case handling person can search by flashing light as a clue. When the mobile phone is not in the pocket, the relevant video is checked, and a case handling person can compare pictures shot by the mobile phone to locate the suspects.
Therefore, the method and the device can help the user to recover the stolen mobile phone. When the stolen mobile phone is detected, the suspected person in the monitoring video can be rapidly and accurately positioned according to the flicker of the light source and/or the picture shot by the mobile phone. Meanwhile, the method is not easy to be found by suspects. In addition, the mobile phone saves more electricity and flow in the tracked process, and the standby time of the mobile phone can be prolonged, so that more time is available for collecting information, and the suspects can be conveniently positioned.
