The GPS space system includes 24 satellites (21 working satellites and 3 spare satellites) that are located over 20200 km from the ground with a 12 hour period of operation. The satellites are uniformly distributed on 6 orbit planes (4 satellites on each orbit plane), and the orbit inclination angle is 55 degrees. The distribution of satellites enables more than 4 satellites to be observed anywhere and anytime in the world, navigation information can be prestored in the satellites, and the navigation accuracy of the satellites is gradually reduced along with the time due to the problems of atmospheric friction and the like.

The Ground control system comprises a monitoring Station (Monitor Station), a main control Station (Master Monitor Station) and a Ground Antenna (Ground Antenna), and is responsible for collecting information returned by satellites and calculating data such as satellite ephemeris, relative distance, atmospheric correction and the like.

The user equipment part is the GPS signal receiver. The main function of the satellite tracking system is to capture satellites to be detected selected according to a certain satellite cut-off angle and track the operation of the satellites. When the GPS signal receiver captures the tracked satellite signals, the pseudo distance and the change rate of the distance between the receiving antenna and the satellite can be measured, and data such as satellite orbit parameters and the like can be demodulated. According to the data, a micro-processing computer in the GPS signal receiver can perform positioning calculation according to a positioning calculation method, and information such as longitude and latitude, altitude, speed, time and the like of the geographic position of the user is calculated.

The article positioning method provided by the embodiment of the application can be applied to computer equipment with stronger data processing capability. In a possible implementation manner, the article positioning method provided by the embodiment of the application can be applied to a personal computer, a workstation or a server, namely, the function of positioning the article lost by the user can be realized through the personal computer, the workstation or the server. The object positioning method is applied to a background server of an application program, so that a terminal provided with the application program can realize the function of positioning objects lost by a user by means of the background server.

FIG. 1 illustrates a schematic diagram of a computer system provided in an exemplary embodiment of the present application. The computer system 100 includes a terminal 110 and a server 120, where the terminal 110 and the server 120 communicate data through a communication network, alternatively, the communication network may be a wired network or a wireless network, and the communication network may be at least one of a local area network, a metropolitan area network, and a wide area network.

In one possible implementation, server 120 is a background server for applications in terminal 110.

As shown in fig. 1, in this embodiment, a social application is running in the terminal 110, the user selects an item to be found in the social application, and after clicking a determination control, the terminal 110 sends a search request for finding the item to the server 120, where the search request carries information about the item that the user needs to find and information about the moment when the user finds that the item is lost. In the embodiment of the application, the user searching for the object is named as an initiator, and refers to a person initiating the object searching request.

After receiving the object searching request of the terminal 110, the server 120 acquires the positioning information 11 of the initiator, where the positioning information 11 of the initiator refers to the positioning coordinates sent to the server by the terminal 110 every time period N (unit is minutes). The server 120 generates a movement path range map 12 for the user for a period of time based on the positioning information 11 for the period of time, for example, the user finds the positioning information for the first two hours of losing the article, and the server 120 generates the movement path range map 12 for the user based on the positioning information for the two hours. The moving path range fig. 12 is a circle having different sizes generated from the location coordinate points moved by the user, and is the largest circle corresponding to the location coordinate point at the closest time to the user finding the lost article, and the smallest circle corresponding to the location coordinate point at the farthest time to the user finding the lost article. A tangent is made between two adjacent circles, and the tangent and the circles form a closed area, which is an area where an article may be lost, namely a search area 13.

The server 120 screens the search area 13 for users 14 that have an account relationship with the originator. There are multiple users moving in the search area 13, which may or may not have an account relationship with the initiator, and the server 120 determines the users from the search area 13 that have an account relationship with the initiator and generates the recommendation list 15 based on the users that have an account relationship with the initiator.

The server 120 sends the recommendation list 15 to the terminal 110, the recommendation list 15 is displayed on the terminal 110, the user initiates an object searching invitation to the account according to the user information in the recommendation list 15, and the lost article is searched for by the help of the object searching request account.

It can be understood that the above embodiment only takes a social application program in a terminal as an example, and in an actual use process, the above object positioning method can also be applied to an application program specially used for searching objects, which is not limited in this embodiment of the present application.

FIG. 2 illustrates a flow chart of a method for locating an item provided in an exemplary embodiment of the present application. This embodiment is described by taking the method for the terminal 110 in the computer system 100 shown in fig. 1 as an example, and the method includes the following steps:

step 201, displaying an item searching interface, wherein the item searching interface comprises an item with a binding relation with a first user account.

An application program is installed and operated on the terminal 110 used by the user, and the application program has a positioning function and a social function, wherein the positioning function means that the application program can acquire positioning coordinates of the terminal 110, and the social function means that the user performs chat communication or information sharing with other users through the application program. Illustratively, the application includes at least one of an instant messaging application, an information sharing application, a shopping application, and a group purchase application. The user looks for the lost target item through the application.

Illustratively, terminal 110 also runs a host-dependent applet that has a location function as well as a social function by which the user looks for lost target items.

Illustratively, the terminal 110 also operates a browser in which an item search page is displayed, through which the user searches for the lost target item.

In one example, as shown in the left diagram of fig. 3, a social application is running in the terminal 110, the user initiates the "find function" of the social application to enter the item searching interface 20, and a headset 21 having a binding relationship with the first user account is displayed in the item searching interface 20. The binding relationship is used for indicating that the association relationship exists between the first user account and the article. Illustratively, the user has an earphone 21, and when the user logs in the social application program by using the first user account, the social application program establishes a binding relationship between the earphone 21 and the first user account by using the earphone 21; alternatively, the headset 21 is a bluetooth headset, a connection is established with the terminal used by the user, and the social application invokes the connection record to establish a binding relationship between the headset 21 and the first user account.

Step 202, in response to receiving a first selection operation on the item finding interface, determining a selected target item, and displaying an account recommendation list.

When the terminal used by the user is a mobile terminal with a touch display screen, such as a smart phone, a tablet computer and a smart watch, the first selection operation includes at least one of the following operations: single click operation, double click operation (including single-finger double click and double-finger double click), long press operation, sliding operation, drag operation, hover operation, and combinations thereof.

When the terminal used by the user is a terminal having an external input device such as a desktop computer to which a subsequent mouse is connected, the first selection operation includes a single mouse operation, a double-click mouse operation, a right-click mouse operation, a slide wheel operation, and a combination thereof.

Illustratively, the user uses the terminal as a smart phone, as shown in the left diagram of fig. 3, the target object to be searched by the user is an earphone 21, the user clicks a control corresponding to the earphone 21, then clicks a "confirm" control 22, and the interface jumps to the interface shown in the right diagram of fig. 3, and an account recommendation list 23 is displayed in the interface.

In response to receiving the second selection operation on the account recommendation list, step 203, sending, to the selected at least one second user account, finding information, the finding information including item information of the target item.

When the terminal used by the user is a mobile terminal with a touch display screen, such as a smart phone, a tablet computer and a smart watch, the second selection operation includes at least one of the following operations: single click operation, double click operation (including single-finger double click and double-finger double click), long press operation, sliding operation, drag operation, hover operation, and combinations thereof.

When the terminal used by the user is a terminal having an external input device such as a desktop computer to which a subsequent mouse is connected, the second selection operation includes a single mouse operation, a double-click mouse operation, a right-click mouse operation, a slide wheel operation, and a combination thereof.

Illustratively, the user using terminal is a smart phone, as shown in the right diagram of fig. 3, the user selects the user account for receiving the finding information by clicking a selection box corresponding to the account header. When the 'number-checking' mark is displayed in the selection frame, the user account corresponding to the 'number-checking' mark is indicated to be selected as an object for receiving the finding information. It will be appreciated that the user may also deselect a selected user account, such as by clicking once more in a dialog box displaying the "number" flag, and deselect the user account to receive the found information.

When the user selects the user account that receives the seeking information, the one-click send invitation control 24 is clicked, and the seeking information is sent to the selected user account, wherein the seeking information comprises the article information of the target article. If the user selects that the target object to be found is the headset 21, the object information includes at least one of appearance information, model information, name information, and chip serial number information of the headset 21.

The second user account has a friend relation with the first user account, or the second user account has a temporary session relation with the first user account, or the second user account does not have a friend relation with the first user account.

Step 204, receiving article positioning information of the target article sent by the second user account.

Illustratively, the first user corresponds to a first user account and the second user corresponds to a second user account. After receiving the article information of the target article, the second user accounts for helping the first user to find the target article through the article information, and after the second user finds the target article, the second user accounts for sending the article positioning information of the target article to the first user accounts. For example, the second user sends item location information for the target item via a location function to a chat dialog with the first user.

Illustratively, after receiving the finding information, the second user account can autonomously select whether to help the first user find the target object. For example, after the second user account receives the finding information, a prompt message is displayed on a terminal used by the second user, where the prompt message is: do you accept a hunt invitation from the first user? Selecting "yes" or "no". The second user selects 'yes', which indicates that the second user accepts the invitation of searching objects from the first user, and the second user account can receive the object information of the target object; and the second user selects no, which indicates that the second user refuses the invitation to find objects from the first user, and the second user account does not receive the object information of the target object.

In summary, according to the method provided by the embodiment, the account recommendation list is displayed for the user through the first selection operation applied by the user on the article searching interface, the second user account is selected on the account recommendation list by the user, and the article searching information is sent to the selected second user account (at least one second user account), so that the user corresponding to the second user account receiving the article searching information can help the user to search for the target article together, the probability of finding the target article is increased, and meanwhile, the searching efficiency of the target article is improved.

Fig. 4 shows a flowchart of an article positioning method according to another exemplary embodiment of the present application. This embodiment is described by taking the method for the terminal 110 in the computer system 100 shown in fig. 1 as an example, and the method includes the following steps:

step 401, displaying an item searching interface, wherein the item searching interface comprises an item having a binding relation with a first user account.

As shown in the left diagram of fig. 5, the item finding interface 20 includes a headset 21, a wristband, and an electronic pen in binding relation to the first user account. Each item corresponds to a grid, and a user can view other items with binding relations by sliding the grids left and right.

Step 402, according to the target object selected by the first selection operation, sending a searching request to the server, wherein the searching request carries positioning information of the first user account and object information of the target object.

Illustratively, when the user selects the target object to be found, the identity of the user needs to be verified in order to prevent misoperation of the non-user himself. The verification mode is as follows:

1. and in response to receiving a first selection operation on the item finding interface, displaying an authentication interface, the authentication interface including at least one of a password input interface, a fingerprint input interface, and a face recognition interface.

Illustratively, when the user clicks on the headset 21, and then clicks on the "ok" control 22, an authentication interface 25 is displayed, as shown in the middle diagram of fig. 5, the authentication interface 25 being a face recognition interface.

2. And in response to receiving the identity verification information of the first user account, verifying the identity of the first user account.

In some embodiments, the authentication interface 25 is a face recognition interface, i.e., the user aligns the face to the scan box 26 and clicks the start recognition control 27 to perform authentication by recognizing whether the face authentication is the user's own operation. In other embodiments, the authentication interface 25 is a password input interface in which a password is entered to authenticate that the user is himself or herself, the password being not less than four digits; in other embodiments, the authentication interface 25 is a fingerprint entry interface in which a fingerprint is entered to verify whether it is the user's own operation, the fingerprint being entered by the user touching a physical key or touching a fingerprint acquisition area on the terminal.

Step 403, in response to receiving the marked user account sent by the server, displaying an account recommendation list according to the marked user account, where the marked user account is obtained after the server marks the user account that meets the searching condition according to the searching request.

The server obtains a moving path corresponding to the first user account according to the searching request, generates a searching area according to the moving path of the first user account, and determines the user account which is positioned in the searching area and meets the searching condition. The server marks the user account which accords with the object searching condition to obtain a marked user account, and the server sends the marked user account to the first user account.

When the identity of the first user account matches with the pre-stored identity (identity information of the first user account is verified), the terminal corresponding to the first user account displays an account recommendation list 23 as shown in the right diagram of fig. 5. The account recommendation list is generated by a terminal corresponding to the first user account according to the marked user account sent by the server.

And responding to the successful authentication of the first user account, and receiving the marked user account sent by the server, wherein the terminal corresponding to the first user account displays an account recommendation list. Schematically, when the authentication is successful, authentication success information is displayed on the authentication interface, and the authentication success information is used for prompting the first user account to pass the authentication.

Step 404, in response to receiving the second selection operation on the account recommendation list, sending the found information to the selected at least one second user account, the found information including item information of the target item.

As shown in the right diagram of fig. 5, the account recommendation list includes a selection frame, where the selection frame corresponds to the number of second user accounts one by one. The user can autonomously select the user account for receiving the finding information.

And sending the sought article to the selected at least one second user account in response to receiving the determined selection operation on the selection frame. It will be appreciated that the user may cancel the selected second user account and, in response to receiving a cancel selection operation on the selection box, cancel selecting the second user account that received the found information.

If the user initiates the "find process" for the first time, a dialog box pops up under the interface for the user to select "whether to allow sharing of location information in the find relationship? (only visible when the find is initiated, the remaining states are not visible) ", with two" yes "and" no "options selectable by the user. In some embodiments, the user may be queried each time the user initiates a "hunting process" whether the user shares location information, the user may set whether to query each time or whether to never query.

In the state of 'yes', the next operation can be carried out, the system can automatically generate an 'account recommendation list', the account marked with a symbol at the upper left corner of the account head portrait represents the person belonging to the 'bound finding relation', and if no symbol mark exists, the person is the person of the 'unbound finding relation'.

The user clicks the "one-click invite" control 24, and the user initiates an invitation to all "recommended accounts" by default, and may manually select, for example, by selecting a "full-selection" selection box, to send the found information to all people in the account recommendation list, or by clicking the top right corner of the friend avatar to cancel the person who does not want to receive the found information, for example, by selecting a "full-non-selection" selection box, to cancel the found information to all people in the account recommendation list.

Step 405, receiving item location information of the target item sent by the second user account.

Illustratively, the object to be sought contains a radio frequency chip or a patch containing a radio frequency chip. A radio frequency identification reader (Radio Frequency Identification, RFID) in the terminal can determine the orientation of the item relative to the RFID reader based on signals from the RFID chip to which the item is bound. For example, the distance of the target item from the RFID reader may be determined by the strength of the signal received by the RFID reader or by adjusting the power emitted by the RFID reader (the emitted power is related to the maximum distance the reader can read the RFID chip), and the distance may be displayed in a social application.

The first user account corresponds to the first user, the second user account corresponds to the second user, when the second user account receives the object searching information, the server simultaneously sends the chip serial number of the target object to the second user account, and invokes an RFID reader in a terminal used by the second user, and sends radio frequency signals with a certain frequency through a transmitting antenna of the RFID reader.

Schematically, the position of the target object is determined by a passive radio frequency identification mode, no power supply is arranged in the passive RFID chip, and the passive RFID chip is driven by receiving electromagnetic waves. When a terminal carried by a second user moves to a position where a target object to be found is near, an RFID chip bound with the target object enters a magnetic field corresponding to the terminal and generates induced current, information such as a self serial number and the like is sent out through a built-in sending antenna of a card in the form of a carrier signal, a receiving antenna of an RFID reader in the terminal receives the carrier signal and decodes the carrier signal to obtain a chip serial number of the RFID chip, the decoded chip serial number is compared with the chip serial number received from a server, when the two are identical, the position where the target object to be found is determined to be near, the second user can find the target object, and the position coordinate of the target object is sent to a first user account. If the second user account refuses to receive the article searching information, the first user account cannot receive the position information of the target article.

Illustratively, the position of the target object is determined by means of active radio frequency identification, and the active RFID chip is provided with a power supply. The RFID chip bound with the target object sends a carrier signal with a certain frequency, the carrier signal carries information such as the serial number of the RFID chip, when the RFID reader in the terminal reads the carrier signal, the carrier signal is decoded, whether the chip sequence carried in the carrier signal is identical to the chip sequence received from the server is analyzed, and if the chip sequence is identical to the chip sequence received from the server, the target object to be searched is determined to be nearby.

In some embodiments, the location of the target item may also be determined by means of semi-active radio frequency identification. Semi-active RFID chips have a power supply that is used only for auxiliary support of the voltage required for the chip to operate or to power the circuitry that maintains the data. When the semi-active RFID chip does not enter the working state, the semi-active RFID chip is in a dormant state, which is equivalent to a passive RFID chip; when the semi-active RFID chip enters a reading area corresponding to an RFID reader of the terminal, the semi-active RFID chip is excited by a radio frequency signal sent by the RFID reader and enters a working state, and a power supply in the RFID chip is used for compensating the condition of insufficient radio frequency field intensity of the position of the target object. It will be appreciated that the RFID reader determines the location of the target item by reading the carrier signal of the semi-active RFID chip.

Illustratively, the location of the target item is determined by bluetooth technology. The target article is provided with a Bluetooth module, the target article sends a broadcast message through the Bluetooth module, the broadcast message carries an article identifier of the target article (or information such as a chip serial number of the target article), when the second user carries the terminal to move to the vicinity of the target article, the terminal receives the broadcast message sent by the target article through the Bluetooth module, thereby acquiring the article identifier of the target article (or information such as the chip serial number of the target article), compares the article identifier with the article identifier (or the information of the chip serial number of the target article) received from the server, and determines that the target article to be searched is in the vicinity if the article identifier and the information of the chip serial number of the target article are the same.

In summary, in the method of the embodiment, the account recommendation list is displayed for the user through the first selection operation applied by the user on the article searching interface, and the second user account is selected on the account recommendation list by the user, so that the article searching information is sent to the selected second user account (at least one second user account), so that the user corresponding to the second user account receiving the article searching information can help the user to find the target article together, the probability of finding the target article is increased, and meanwhile, the searching efficiency of the target article is improved.

The user account meeting the object searching condition is marked according to the object searching request by the server, so that the terminal corresponding to the first user account can generate an account recommending list according to the marked user account, the server can recommend the user account meeting the user requirement to the first user account, the probability of finding the target object is increased, and meanwhile, the searching efficiency of the target object is improved.

Identity information of the first user account is intuitively verified through the identity verification interface, so that misoperation of other people on articles corresponding to the user is prevented, and privacy disclosure is prevented.

In an alternative embodiment based on fig. 4, the user is illustrated looking at his own bound items.

Step 41, displaying a first binding user interface comprising items having a binding relationship with a first user account.

As shown in the left diagram of fig. 6, the user starts the social application on the terminal, enters the function list, displays the "find one" control 31 in the function list, and by clicking the "find one" control 31, the terminal displays the first binding user interface 32 as shown in the upper right diagram of fig. 6. In some embodiments, the "find one" control is again named a find one control, and the first binding user interface 32 is again named a device binding interface or "My devices" interface, which embodiments of the present application do not limit.

In the first binding user interface 32, the bound device 1 and device 2 are displayed, and the device model number or chip serial number of the device 1 and device 2, respectively, are displayed. Also displayed in the first binding user interface 32 is a binding control 33.

In response to receiving the first binding operation on the first binding user interface, a binding relationship is established between the first item and the first user account, step 42.

The user clicks the binding control 33 to establish a binding relationship with the unbound first item, for example, the user clicks the binding control 33 to establish a binding relationship between the first user account and a bracelet, which is an item that the user has not previously established a binding relationship. Binding in this embodiment of the present application refers to adding an item to be bound to the first binding user interface, where no user is required to actually connect the item to the terminal (e.g. connect to the same wireless network or connect via bluetooth).

It should be noted that, step 41 is performed before step 401, and when the first user account is not bound to any article, the first user account is bound to the article, and then the "searching process" in the above embodiment is performed.

In summary, in the method of the embodiment, the user-bound item is intuitively displayed through the first binding user interface, so that the user can quickly establish a binding relationship between the new item and the first user account.

In an alternative embodiment based on fig. 4, a user account is described that views an item for which a binding relationship is established with an item corresponding to editing a first user account.

Step 43, a second binding user interface is displayed, the second binding user interface including a second user account.

As shown in the right hand diagram of fig. 6, the display may be toggled between the first binding user interface 32 and the second binding user interface 34. A plurality of second user accounts are displayed on the second binding user interface 34, including user accounts for which a binding relationship is established with items corresponding to the first user account and user accounts for which a binding relationship is not established. As shown in the lower right diagram of fig. 6, a second user account with an established binding relationship is included below the bound option, and it should be noted that a second user account below the bound option establishes a binding relationship with one or more articles.

Step 44, in response to the second user account having a binding relationship with the first item, and the second binding user interface receiving the first editing operation, unbinding the binding relationship; or, in response to the second user account having a binding relationship with the first item and the second binding user interface receiving a second editing operation, binding the second user account with the second item, where the first item and the second item are items corresponding to the first user account.

As shown in the lower right diagram of fig. 6, an edit control for editing the binding relationship between the second user account and the article is displayed on one side of each second user account. Illustratively, the user clicks the edit control to edit the item information for the item bound to the second user account. For example, the second user account a has a binding relationship with the bracelet, and the user can release the binding relationship by clicking the editing control. For another example, the second user account a has a binding relationship with the bracelet, and the user establishes the binding relationship between the earphone and the second user account a by clicking the editing control. It should be noted that the step of editing the binding relationship may be performed at any time.

When the user clicks the "one-touch invite" control 35, the item find interface 20 is displayed as shown in the right-hand diagram of fig. 6, thereby proceeding to the select target item to be found for execution step (step 401).

In summary, in the method of the embodiment, the second user account with the binding relationship is intuitively displayed through the second binding user interface, so that the efficiency of browsing information by the user is improved.

In an alternative embodiment based on fig. 4, the user account establishment binding is described.

Step 45, displaying a second binding user interface, the second binding user interface including a second user account.

As shown in the lower right diagram of fig. 6, a plurality of second user accounts, which are second user accounts that do not establish a binding relationship with any item corresponding to the first user account, are displayed below the unbound option.

Step 46, in response to the second user account having no binding relationship with the article corresponding to the first user account, and the second binding operation being received on the second binding user interface, a binding relationship between the second user account and the article corresponding to the first user account is established.

And displaying a binding control in the second binding user interface, clicking the binding control by a user, and establishing a binding relationship between the second user account and the article to be bound. A second user establishes a binding relationship with one or more items. It should be noted that, if the second user account has a binding relationship, the step of establishing the binding relationship may be performed at any time, and if the binding relationship is not established for the second user account, the object searching process may be performed only by establishing the binding relationship.

In summary, in the method provided by the embodiment, the second user account without the binding relationship is intuitively displayed through the second binding user interface, so that the user can directly establish the binding relationship between the second user account and the corresponding article of the first user account through the second binding user interface, and the efficiency of establishing the binding relationship by the user is improved.

In an alternative embodiment based on fig. 4, the first user account receiving the finding information is described.

Step 47, displaying a first binding user interface, where the first binding user interface includes at least one of binding request information and finding request information sent by the second user account, where the binding request information is used to request the first user account to establish a binding relationship with an item corresponding to the second user account, and the finding request information is used to characterize a request sent by the second user account to find the item.

Illustratively, the first user account receives the article searching information. As shown in the left diagram of fig. 7, the user starts the social application on the terminal, enters the function list, displays the "find one find" function in the function list, and displays the prompt information 51 in the "find one find" function column. The user clicks on the find column and enters the first binding user interface 32 as shown in the right hand diagram of fig. 7. Binding request information 52 and hunting request information 53 are also displayed on the first binding boundary surface 32. The binding request information is that the second user account requests the first user account to establish a binding relationship with the article corresponding to the second user account, and the binding relationship is permanent unless the binding relationship is released manually. The object searching request information belongs to disposable information, namely, after the object searching process is finished, the binding relation between the first user account and the object corresponding to the second user account is released.

And step 48, obtaining article information of the article corresponding to the second user account in response to receiving the consent operation on the first binding user interface.

When the first user account agrees to receive the object searching information sent by the second user account, the server sends the corresponding object information to the first user account.

In summary, in the method provided in this embodiment, the object searching information received by the first user account is intuitively displayed through the first binding user interface, so that the first user account participates in the object searching process quickly.

The process of generating the account recommendation list is described below in connection with a server.

FIG. 8 shows a diagram of a hunting flow provided in an exemplary embodiment of the present application, including the following steps:

step 801, a terminal corresponding to a first user account initiates a searching request.

And a social application program is installed and operated on the terminal corresponding to the first user account, and a searching request is initiated through the social application program.

Step 802, the server retrieves positioning data corresponding to the first user account X hours before the lost object.

And the terminal corresponding to the first user account periodically sends positioning information to a background server of the social application program through a GPS technology.

In step 803, the server determines the user account meeting the searching condition, which is located in the searching area when the first user account initiates the searching request.

Step 803 may be replaced with the following steps:

in step 8031, the server receives positioning information of the first user account.

In step 8032, the server obtains a movement path corresponding to the first user account according to the positioning information, where the movement path includes a movement path formed by positioning coordinate points periodically sent to the server by the terminal corresponding to the first user account in the movement process.

The first user corresponds to the first user account, and when the first user carries the terminal to move, the moving path of the first user is recorded through the GPS technology of the terminal. As shown in fig. 9, a section of positioning coordinate points (6) are intercepted to form a moving path corresponding to the first user account, and the section of positioning coordinate points is schematically a moving path (X is a positive integer) formed by the positioning coordinate points corresponding to X hours before the object is lost, and the larger the number of the positioning coordinate points is, the closer to the moment when the user finds that the target object is lost.

In step 8033, the server generates a search area according to the movement path.

The search area refers to an area where the target object may be located, and is generated by:

1. The server acquires positioning coordinate points in a moving path in a first time interval, wherein the positioning coordinate points are arranged in sequence from small to large with the time interval of a first time, the positioning coordinate points correspond to positioning numbers in descending order, the first time is the time when the target object has the maximum loss probability, and the first time interval is used for representing the time period where the target object is lost.

Illustratively, the latest moment when the first user (initiator) finds that the target object is lost is set, the probability of the target object being lost is maximum, and the server is preset with the maximum searching radius maxR (unit: meters) of the moving area; the server sets a minimum searching radius minR (unit: m) of the moving area in advance from the farthest moment when the initiator finds that the target object is lost, and the loss probability of the target object is minimum. The server presets a maximum seek Time range maxTime (unit: minutes, and the unit of parameters related to Time below is minutes), and the initiator can select a Time value Time in the interval of (0, maxTime), for example, the first two hours (120 minutes) from the moment of finding the lost object, wherein the Time value Time is an integer multiple of N, N is a period of sending a positioning coordinate point to the server by the terminal, the unit is minutes, and the sizes of the maximum seek radius and the minimum seek radius are adjustable.

As can be seen from the above setting, in the Time value Time minute (first Time interval), the total number of positioning coordinate points is dot_sum=time/N, and when the initiator initiates the object searching request, the server generates a group of coordinate points with Time sequence: n=0 is the earliest point in time (i.e., the point in time furthest from the discovery of the loss of the item), and n=dot_sum-1 is the point in time closest to the user's discovery of the loss of the item (the first moment).

2. And sequentially generating moving areas corresponding to the positioning coordinate points according to the positioning numbers in descending order, wherein the moving areas are the areas where the terminals corresponding to the user accounts which meet the searching conditions are located when moving.

The server acquires a maximum searching radius and a minimum searching radius, wherein the maximum searching radius corresponds to the maximum probability of finding the target object, and the minimum searching radius corresponds to the minimum probability of finding the target object; the server obtains the moving radius of the moving area corresponding to the ith positioning coordinate point according to the positioning number, the maximum searching radius, the minimum searching radius and the number of the positioning coordinate points, wherein i is a positive integer; generating a moving area corresponding to the ith positioning coordinate point according to the ith positioning coordinate point and the moving radius; and repeating the step of generating the moving areas corresponding to the positioning coordinate points until the positioning coordinate points in the first time interval respectively generate the corresponding moving areas.

The server generates a movement region at each location coordinate point according to the following formula:

the server starts with a position number of n=dot_sum-1, generates a movement region corresponding to the position coordinate point at (dot_sum-1), then generates a movement region corresponding to the position coordinate point at (dot_sum-2), and so on until a movement region corresponding to the position coordinate point at 0 is generated, as shown by movement region 61 in fig. 10. In this embodiment of the present application, the mobile area indicates an area where a terminal corresponding to a user account that meets the searching condition is located when moving, that is, in a process of moving the first user, other users may exist around the mobile area, and the server uses the other users around the first user as candidate objects for receiving the searching information by defining an area. The embodiment of the present application will be described by taking the example that the moving area is circular. The user accounts which meet the object searching condition comprise user accounts which have a friend relation with the first user account or user accounts which do not have a friend relation.

3. And connecting the moving areas corresponding to the adjacent positioning numbers to form a searching area.

The server makes a tangent line from a moving area corresponding to the ith positioning coordinate point to a moving area corresponding to the (i+1) th positioning coordinate point, wherein i is a positive integer; repeating the step of making a tangent line between the moving areas corresponding to the adjacent positioning numbers until the moving areas in the first time interval are connected by the tangent line; the search area is formed from the tangentially connected moving area.

As shown in fig. 11, a closed pattern formed by the tangential line and the moving area 61 is a search area.

In some embodiments, since the moving area 61 is related to the position of the positioning coordinate point corresponding to the first user account, there may be a distance between two positioning coordinate points, and the moving areas corresponding to the two positioning coordinate points are similar, so that one moving area completely includes the other moving area, as shown in fig. 12. In this case, the server will recreate a new moving area for the two moving areas, the center of the new moving area is the end point of the connecting line of the two positioning coordinate points as the center, and the radius is the sum of the radii of the two circular areas. If the newly created moving area still completely contains other moving areas, the above process of creating moving areas is repeated until the other moving areas are no longer completely contained. When the moving area no longer completely contains other moving areas, a tangent line between the moving areas is made, and the tangent line between the two moving areas is made in the descending order of the positioning numbers of the positioning coordinate points, for example, a tangent line is made from the moving area at n=5 to the moving area at n=4, a tangent line is made from the moving area at n=3 to the moving area at n=2, and the like.

In step 804, the server marks the user account that meets the searching condition.

The server determines a marked user account from the searching area, sends the marked user account to a terminal corresponding to the first user account, wherein the marked user account is a user account which is positioned in the searching area and accords with the searching condition, the marked user account is used for displaying an account recommendation list for the terminal corresponding to the first user account, the account recommendation list is used for providing a second user account for receiving searching information for the first user account, and the second user account is used for sending article positioning information of a target article to the first user account according to the received searching information. The target item is an item determined when a terminal corresponding to the first user account receives a first selection operation.

The user account conforming to the object searching condition comprises a user account having a friend relation with the first user account, for example, the server determines the user account having the friend relation with the first user account from the searching area, and takes the user account as the user account conforming to the object searching condition.

The user account conforming to the object searching condition comprises a user account which does not have a friend relation with the first user account and has a distance from a terminal corresponding to the first user account smaller than a preset distance (such as 500 meters), and the user account is taken as the user account conforming to the object searching condition.

The user accounts which meet the object searching condition comprise user accounts which do not have friend relation with the first user account and are located in a mobile area with the largest area and the time of which exceeds a preset threshold value, and the user accounts are taken as the user accounts which meet the object searching condition. For example, as shown in fig. 10, if the area of the corresponding moving area is maximum when n=5, the user account that is located in the moving area and has a duration exceeding a preset threshold (for example, 3 hours) is taken as the user account that meets the searching condition.

The server marks the user account which accords with the object searching condition to obtain a marked user account. In some embodiments, the social application will close the find request if the sponsor does not close the find request within a valid time after the initiate of the find request.

And step 805, the marked user account is sent to the terminal corresponding to the first user account.

Step 806, the terminal corresponding to the first user account displays the account recommendation list.

The first user selects a second user account for receiving the article searching information from the account recommendation list, and sends the article searching information to the selected second user account, when the target article is found, the second user account sends article searching success information to the first user account, and the article searching success information is used for representing the information sent when the target article is found successfully. In some embodiments, the first user account sends the object searching success information to the server, and the server records the searching process of the target object after receiving the object searching success information sent by the first user account.

In summary, in the method of the embodiment, the server generates the searching area for delineating the possible target object according to the movement path corresponding to the first user account, so as to determine the user account meeting the object searching condition, in which the movement path is located in the searching area, and screen the user account meeting the object searching condition, which has an account relationship with the first user account, from the user accounts meeting the object searching condition, and mark the user account, so that the account recommended to the first user account by the server according to the movement path meets the user requirement, the probability of finding the target object is increased, and the searching efficiency of the target object is improved.

And sequentially generating moving areas according to the positioning coordinate points in the moving path corresponding to the first user account by the server, enabling the possible areas of the target object to be represented by the moving areas, associating the moving areas with the moving ranges corresponding to the user accounts meeting the object searching conditions, determining the areas where the target object is likely to be located and which user accounts are associated, and further sending object searching information to the user accounts. The probability of finding the target object is increased, and meanwhile, the searching efficiency of the target object is improved.

The size of the moving area is related to the probability of finding the target object, namely the larger the probability of finding the target object is, the larger the moving area is, the time when the user finds that the target object is lost is taken as the time when the probability of finding the target object is maximum, the moving area is generated by the positioning coordinate points corresponding to the time when the user finds that the target object is lost, and the positioning coordinate points far away from the time are sequentially generated into the moving area, so that the moving area can accurately represent the probability of losing the object, and the user can be ensured to send the hunting information to more other users.

The server screens the users possibly providing assistance based on the search area, and the trace data of the users providing assistance are not sent to the users to be assisted, so that the privacy of the users providing assistance is protected.

In the above embodiment, the server screens the user account that meets the object searching condition according to the searching area generated by the moving path corresponding to the first user account, and in addition, the server may also search the user account that meets the object searching condition in other manners.

In some embodiments, the server obtains the location coordinate point 131 at the time when the first user finds that the item is lost, calculates the movement radius 132 two hours forward from the time (8 km for a walking speed of 4 km/h, and two hours), e.g., ten zero-fifths a am when the first user finds that the item is lost, and eight zero-fifths two hours forward. The server makes a circle (search area) with the location coordinate point 131 as a center, and uses the user account in the circular area as the user account meeting the object searching condition, as shown in fig. 13. In other embodiments, the user account located in the search area for more than 90 minutes is used as the user account meeting the searching condition by rounding (search area) in the above manner.

In some embodiments, the server obtains the first location coordinate point 141 at the moment when the first user finds that the article is lost, and when the server determines that the first user is located at the first location coordinate point 141, the number of first users around the first user is within a preset distance range from the first user (for example, the first preset distance is 500 meters). Then, the server acquires a second positioning coordinate point 142 corresponding to the closest moment to the first positioning coordinate point 141, and determines the second user number of surrounding users when the first user is located at the second positioning coordinate point 142. Circle 1 (first radius R1) is made for the first positioning coordinate point 141, and circle 2 (second radius R2) is made for the second positioning coordinate point 142. Comparing the first user number with the second user number, and if the first user number is larger than the second user number, then R1 is smaller than R2; if the first number of users is less than the second number of users, R1 is greater than R2. When the number of users around the first user is small, the range of the searching area needs to be enlarged, so that more users are ensured to be used as alternative users meeting the searching condition. Likewise, a search area is formed by cutting a line between two circles, as shown in fig. 14 (a) and 14 (b). Illustratively, a user account meeting at least one of the following conditions is taken as a user account meeting the object searching condition: the method comprises the steps of obtaining a user account with a friend relation with a first user account in a search area, obtaining a user account with a distance smaller than a preset distance with the first user account in the search area, obtaining a user account with time exceeding a time threshold in the search area, and obtaining a user account without a friend relation with the first user account in the search area.

The method and the device are described for the situation of stranger object searching in the embodiment of the application. If the friend range is too small to meet the searching requirement, the searching crowd can be properly expanded to the non-friend crowd, and the crowd can be specifically classified into the following three priorities.

First, in conjunction with the "people nearby" function, when user A initiates a seek request, strangers in the vicinity of user A will be the first priority. Secondly, dividing different levels according to the time length of the user in the area (a circle with the radius of 1 km) within X hours before the article is lost, taking the area with the time length exceeding 5 hours as a key area, and taking the person in the area as a second priority when the user A initiates the article searching request. Third, among the candidate users after the first two-stage screening, the different levels are also divided according to the time length of the user appearing in the area (a circle with a radius of 1 km), the area with the appearance time length more than 2 hours and less than 5 hours is used as a secondary key area, and when the user A initiates the object searching request, the person in the area is used as a third priority.
