The GPS space system comprises 24 satellites (21 working satellites and 3 spare satellites) located 20200 km above the ground with a 12 hour period of operation. The satellites are uniformly distributed on 6 orbital planes (4 per orbital plane) with an orbital inclination of 55 °. The distribution of the satellites enables more than 4 satellites to be observed anywhere in the world at any time, 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 Master control Station (Master Station) and a Ground Antenna (Ground Antenna), and is responsible for collecting messages sent back by satellites and calculating data such as satellite ephemeris, relative distance, atmospheric correction and the like.

The user equipment part is a GPS signal receiver. The main function of the system is to capture the satellite to be tested selected according to a certain satellite cut-off angle and track the operation of the satellite. After the GPS signal receiver captures the tracked satellite signal, the change rate of the pseudo distance and the distance from the receiving antenna to the satellite can be measured, and data such as satellite orbit parameters are demodulated. According to the data, the microprocessor computer in the GPS signal receiver can perform positioning calculation according to a positioning calculation method, and calculate the longitude and latitude, the height, the speed, the time and other information of the geographic position of the user.

It should be understood that the above embodiment only takes a social application program in the terminal as an example, and in an actual use process, the above item location method may also be applied to an application program specially used for finding objects, which is not limited in this application embodiment.

Fig. 2 shows a flowchart of an article location method provided by an exemplary embodiment of the present application. The embodiment is described by taking the method as an example for the terminal 110 in the computer system 100 shown in fig. 1, and the method includes the following steps:

step 201, displaying an item searching interface, where the item searching interface includes an item having a binding relationship with the first user account.

An application program is installed and run on the terminal 110 used by the user, the application program has a positioning function and a social function, the positioning function means that the application program can obtain 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 finds the missing target item through the application.

Illustratively, the terminal 110 also runs an applet that depends on the host program, which has a location function and a social function, through which the user finds the missing target item.

Illustratively, the terminal 110 further operates a browser, and an item finding page is displayed in the browser, through which the user finds the lost target item.

In one example, as shown in the left diagram of fig. 3, a social application program is run in the terminal 110, the user starts an "article finding function" of the social application program to enter the article finding interface 20, and the headset 21 having a binding relationship with the first user account is displayed in the article finding interface 20. The binding relationship is used for indicating that an association relationship exists between the first user account and the article. Illustratively, the user owns the headset 21, and when the user logs in the social application program using the first user account, the social application program uses the headset 21 to establish a binding relationship between the headset 21 and the first user account; or, the headset 21 is a bluetooth headset, and establishes a connection with a terminal used by the user, and the social application program calls 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 operations, double click operations (including single finger double click and double finger double click), long press operations, slide operations, drag operations, hover operations, 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 mouse is connected, the first selection operation includes a single mouse operation, a double-click mouse operation, a right-click mouse operation, a scroll wheel operation, and combinations thereof.

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

Step 203, responding to the received second selection operation on the account recommendation list, and sending the object searching information to the selected at least one second user account, wherein the object searching information comprises the 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 operations, double click operations (including single finger double click and double finger double click), long press operations, slide operations, drag operations, hover operations, 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 mouse is connected, the second selection operation includes a single mouse operation, a double-click mouse operation, a right-click mouse operation, a scroll wheel operation, and combinations thereof.

Illustratively, the user using terminal is a smart phone, and as shown in the right diagram of fig. 3, the user selects the user account for receiving the article finding information by clicking the selection frame corresponding to the avatar of the account. When the 'number matching' mark is displayed in the selection frame, the user account corresponding to the 'number matching' mark is selected as an object for receiving the article searching information. It is understood that the user may also deselect the selected user account, for example, deselecting the user account to receive the article finding information if the user clicks once more in the dialog box displaying the "number matching" flag.

When the user selects the user account receiving the article searching information, the user clicks the 'one-key sending invitation' control 24 to send the article searching information to the selected user account, and the article searching information comprises the article information of the target article. If the target item selected by the user to be searched is the headphone 21, the item information includes at least one of appearance information, model information, name information, and chip serial number information of the headphone 21.

The second user account has a friend relationship with the first user account, or the second user account has a temporary session relationship with the first user account, or the second user account has no friend relationship with the first user account.

And step 204, receiving the item positioning information of the target item 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 object information of the target object, the second user helps the first user to find the target object through the object information, and after finding the target object, the second user sends the object positioning information of the target object to the first user account through the second user account. For example, the second user sends the item location information of the target item to a chat dialog box with the first user through the location function.

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

In summary, in the method provided in this embodiment, an account recommendation list is displayed for the user through a first selection operation applied by the user on the item search 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 item together, the probability that the target item is found is increased, and the efficiency of searching for the target item is improved at the same time.

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

step 401, displaying an item searching interface, where the item searching interface includes an item having a binding relationship with the first user account.

As shown in the left diagram of fig. 5, the item-finding interface 20 includes a headset 21, a bracelet, and an electronic pen having a binding relationship with the first user account. Each kind of article corresponds to a grid, and a user can check other articles with binding relations by sliding the grids left and right.

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

Illustratively, after the user has selected the target object to be searched, the user's identity needs to be verified in order to prevent a wrong operation by a non-user himself. The verification method is as follows:

1. and responding to the received first selection operation on the article searching interface, and displaying an identity verification interface, wherein the identity verification interface comprises 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 clicks on the "ok" control 22, the authentication interface 25 is displayed, as shown in the middle diagram of fig. 5, where the authentication interface 25 is a face recognition interface.

2. And responding to the received identity authentication information of the first user account, and authenticating the identity of the first user account.

In some embodiments, the authentication interface 25 is a face recognition interface, i.e. by recognizing whether the face authentication is performed by the user himself, the user aligns the face with the scanning box 26 and clicks the start recognition control 27 to perform the authentication. In other embodiments, the authentication interface 25 is a password input interface, and a password is input in the password input interface to verify whether the operation is performed by the user himself, wherein the password is not less than four digits; in other embodiments, the authentication interface 25 is a fingerprint input interface, where a fingerprint is input to verify whether the operation is performed by the user himself, and the fingerprint is input by the user touching a physical key or a fingerprint collection 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 by the server marking a user account meeting the article searching condition according to the article searching request.

The server acquires a moving path corresponding to the first user account according to the article 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 article searching conditions. The server marks the user account which meets 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 is matched with the pre-stored identity (the 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, and displaying an account recommendation list by a terminal corresponding to the first user account. Illustratively, when the identity authentication is successful, the authentication success information is displayed on the identity authentication interface, and the authentication success information is used for prompting that the first user account passes the identity authentication.

And step 404, in response to receiving a second selection operation on the account recommendation list, sending the item searching information to the selected at least one second user account, wherein the item searching information comprises item information of the target item.

As shown in the right diagram of fig. 5, the account recommendation list includes selection boxes, and the selection boxes correspond to the number of the second user accounts one to one. The user can autonomously select the user account for receiving the object searching information.

And sending the searched item to the selected at least one second user account in response to receiving the determined selection operation on the selection frame. It is understood that the user may deselect the selected second user account, and in response to receiving the deselection operation on the selection box, deselect the second user account that received the seek information.

If the user initiates the "finding process" for the first time, a dialog box pops up below the interface for the user to select "whether to allow sharing of location information in the finding relation? (only for the initiation of finding objects visible, the rest of the state invisible) ", the user selectable options have two" yes "and" no ". In some embodiments, the user may be asked whether to share location information each time the user initiates a "seek process," the user may set whether to ask each time or whether to never ask.

In the ' yes ' state, the next operation can be carried out, the system can automatically generate an ' account recommendation list ', the account with the symbolic label at the upper left corner of the account head represents the person who belongs to the ' bound finding relation ', and if no symbolic label exists, the account is the person who does not have the bound finding relation '.

The user clicks the one-click invitation control 24, and the user can initiate invitations to all the recommended accounts by default, and can also manually select the "all-selection" selection box, and send the object seeking information to all the people in the account recommendation list, or click the upper right corner of the friend head to cancel people who do not want to receive the object seeking information, for example, select the "all-no-selection" selection box, and then cancel sending the object seeking information to all the people in the account recommendation list.

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

Illustratively, the target object to be searched contains a radio frequency chip or a patch containing a radio frequency chip. A Radio Frequency Identification (RFID) reader in the terminal may determine the orientation of an item with respect to the RFID reader according to a signal transmitted by an 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 transmitted by the RFID reader (the transmission power is related to the maximum distance the reader can read the RFID chip), and the distance may be displayed in the 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 calls an RFID reader in a terminal used by the second user, and sends a radio frequency signal with a certain frequency through a transmitting antenna of the RFID reader.

Illustratively, the position of the target object is determined in a passive radio frequency identification mode, and the passive RFID chip is driven by receiving electromagnetic waves without a power supply. When a terminal carried by a second user moves to a position near a target object to be searched, an RFID chip bound by the target object enters a magnetic field corresponding to the terminal and generates induction current, information such as a self serial number and the like is sent out through a card built-in sending antenna in a carrier signal mode, 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 chip serial number obtained by decoding is compared with a chip serial number received from a server, when the chip serial number obtained by decoding is the same as the chip serial number received from the server, the target object to be searched 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. And if the second user account refuses to receive the object searching information, the first user account cannot receive the position information of the target object.

Illustratively, the position of the target object is determined by an active radio frequency identification mode, and the active RFID chip is provided with a power supply. The method comprises the steps that an RFID chip bound to a target object sends a carrier signal at a certain frequency, the carrier signal carries information such as a serial number of the RFID chip, when an RFID reader in a terminal reads the carrier signal, the carrier signal is decoded, whether a chip sequence carried in the carrier signal is the same as a chip sequence received from a server or not is analyzed, and if the chip sequence carried in the carrier signal is the same as 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 way 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 chip operation or to power the circuits that maintain 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 to enter a working state, and a power supply in the RFID chip is used for making up the condition that the radio frequency field intensity of the position where the target object is located is insufficient. It will be appreciated that the RFID reader determines where the target item is located 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 object is provided with a Bluetooth module, the target object sends a broadcast message through the Bluetooth module, the broadcast message carries an object identifier of the target object (or information such as a chip serial number of the target object), when a second user carrying the terminal moves to the vicinity of the target object, the terminal receives the broadcast message sent by the target object through the Bluetooth module, so that the object identifier of the target object (or information such as the chip serial number of the target object) is obtained and compared with the object identifier (or chip serial number information of the target object) received from the server, and if the object identifier and the chip serial number information are the same, the target object to be searched is determined to be nearby.

In summary, in the method of this embodiment, an account recommendation list is displayed for the user through a first selection operation applied by the user on the item search 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 item together, the probability of finding the target item is increased, and the efficiency of finding the target item is improved at the same time.

The server marks the user account number which meets the article searching condition according to the article searching request, so that the terminal corresponding to the first user account number can generate an account number recommendation list according to the marked user account number, the server recommends the user account number which meets the user requirement to the first user account number, the probability of finding the target article is increased, and meanwhile the searching efficiency of the target article is improved.

The identity information of the first user account is visually verified through the identity verification interface, so that other people are prevented from carrying out misoperation on the article corresponding to the user, and privacy disclosure is prevented.

The selection frame is arranged on the account recommendation list, so that the user can manually select the target object for sending the object searching information, and the sending efficiency of the object searching information is improved.

In an alternative embodiment based on fig. 4, the user is explained to view his or her bound items.

Step 41, displaying a first binding user interface, wherein the first binding user interface comprises an article having a binding relationship with the first user account.

As shown in the left diagram of fig. 6, the user starts the social application program on the terminal, enters the function list, a "find one" control 31 is displayed in the function list, and by clicking the "find one" control 31, the terminal displays a first binding user interface 32 as shown in the upper right diagram of fig. 6. In some embodiments, the "find one" control is named as an object finding control, and the first bound user interface 32 is named as a device bound interface or a "my devices" interface, which is not limited in this embodiment.

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

Step 42, in response to receiving the first binding operation on the first binding user interface, establishing a binding relationship between the first item and the first user account.

The user clicks the binding control 33 to establish a binding relationship with the unbound first item, and if the user clicks the binding control 33 to establish a binding relationship between the first user account and the bracelet, the bracelet is an item for which the binding relationship has not been established before by the user. The binding in the embodiment of the application refers to adding the article to be bound to the first binding user interface, and does not need to actually establish connection between the article and the terminal (for example, connection to the same wireless network or connection through bluetooth).

It should be noted that, step 41 is executed before step 401, and when there is no article bound to the first user account, the first user account is bound to the article first, and then the "article finding process" in the above embodiment is executed.

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

In an alternative embodiment based on fig. 4, a user account for viewing an item associated with editing a first user account and establishing a binding relationship is described.

Step 43, displaying a second binding user interface, wherein the second binding user interface comprises a second user account.

As shown in the right diagram of fig. 6, the display may toggle between the first binding user interface 32 and the second binding user interface 34. A plurality of second user accounts including a user account having a binding relationship with the article corresponding to the first user account and a user account having no binding relationship are displayed on the second binding user interface 34. 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 items.

Step 44, in response to the second user account having a binding relationship with the first article and the first editing operation being received on the second binding user interface, releasing the binding relationship; or, in response to that the second user account and the first article have a binding relationship and a second editing operation is received on the second binding user interface, binding the second user account and the second article, where the first article and the second article are articles corresponding to the first user account.

As shown in the lower right diagram of fig. 6, an editing control is displayed on one side of each second user account, and the editing control is used for editing the binding relationship between the second user account and the article. Illustratively, the user clicks the edit control to edit the item information of 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 headset 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 "invite to click" control 35, the item search interface 20 shown in the right diagram of fig. 6 is displayed, thereby entering a step of selecting a target item to be searched (step 401).

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

In an alternative embodiment based on fig. 4, the establishment of the binding relationship for the user account is explained.

And step 45, displaying a second binding user interface, wherein the second binding user interface comprises a second user account.

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

And step 46, in response to that the second user account does not have the binding relationship with the article corresponding to the first user account and that a second binding operation is received on the second binding user interface, establishing the binding relationship between the second user account and the article corresponding to the first user account.

And displaying a binding control in the second binding user interface, and clicking the binding control by a user to establish 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 binding relationship established by the second user account already exists, the step of establishing the binding relationship may be performed at any time, and if the binding relationship established by the second user account does not exist, the object-finding process may be performed only by establishing the binding relationship first.

In summary, in the method provided in this embodiment, the second user account without the binding relationship is visually displayed through the second binding user interface, so that the user can directly establish the binding relationship between the second user account and the article corresponding to 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 article seeking information is explained.

And step 47, displaying a first binding user interface, wherein the first binding user interface comprises at least one of binding request information and article searching request information sent by the second user account, the binding request information is used for requesting the first user account to establish a binding relationship with an article corresponding to the second user account, and the article searching request information is used for representing a request for searching the article sent by the second user account.

For illustration, the first user account receives the article-seeking information. As shown in the left diagram of fig. 7, the user starts the social application on the terminal, enters the function list, and displays the "find one find" function in the function list and displays the prompt message 51 in the column of the "find one find" function. The user clicks on the find one column and enters the first binding user interface 32 as shown in the right diagram of fig. 7. Also displayed on the first binding interface 32 are binding request information 52 and finding request information 53. The binding request information is that the second user account requests the first user account to establish a binding relationship with an article corresponding to the second user account, and the binding relationship is permanent unless the binding relationship is released manually. The article searching request information belongs to one-time information, namely after the article searching process is finished, the binding relation between the articles corresponding to the first user account and the second user account is released.

And 48, responding to the received agreement operation on the first binding user interface, and acquiring the item information of the item corresponding to the second user account.

And when the first user account agrees to receive the article searching information sent by the second user account, the server sends the corresponding article information to the first user account.

In summary, the method provided in this embodiment intuitively displays the article-searching information received by the first user account through the first binding user interface, so that the first user account can quickly participate in the article-searching process.

The following describes a process for generating an account recommendation list in connection with a server.

Fig. 8 shows a framework diagram of an object-finding process provided by an exemplary embodiment of the present application, which includes the following steps:

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

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

Step 802, the server retrieves the positioning data corresponding to the first user account for 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 object-finding condition in the object-finding area when the first user account initiates the object-finding request.

Step 803 may be replaced with the following steps:

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

Step 8032, the server obtains, according to the positioning information, a movement path corresponding to the first user account, 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 during 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 moving path corresponding to the first user account is formed by intercepting a segment of (6) positioning coordinate points, which is schematically a moving path (X is a positive integer) formed by 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 the time when the user finds that the target object is lost is.

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

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

1. the server acquires positioning coordinate points in a moving path in a first time interval, the positioning coordinate points are arranged according to the sequence of the time interval from small to large of the first time, the positioning coordinate points have descending positioning numbers, 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 when the target object is lost.

Schematically, the probability of the target object loss is maximum at the closest time when the first user (initiator) finds that the target object is lost, and the server is preset with the maximum searching radius maxR (unit: meter) of the moving area; the loss probability of the target object is the minimum at the farthest moment when the initiator finds that the target object is lost, and the server is preset with the minimum searching radius minR (unit: meter) of the moving area. The server presets a maximum search Time range maxTime (unit: minutes, the following parameter units related to Time are minutes), the initiator can select a Time value Time within an interval of (0, maxTime), for example, two previous hours (120 minutes) from the Time of finding a lost object, where the Time value Time is an integral multiple of N, N is a period for the terminal to send a location coordinate point to the server, and the unit is minutes, and the maximum search radius and the minimum search radius are adjustable in size.

As can be seen from the above setting, in the Time value Time minute (the first Time interval), the total number of the positioning coordinate points is dot _ sum which is Time/N, and when the initiator initiates the object-finding request, the server generates a set of coordinate points in Time sequence: n-0 is the earliest point in time (i.e., the point in time farthest from the discovery of the item loss), and n-dot _ sum-1 is the closest point in time (the first time) at which the user discovers the item loss.

2. And sequentially generating a moving area corresponding to each positioning coordinate point according to the descending positioning numbers, wherein the moving area is an area where a terminal corresponding to the user account meeting the object searching condition is 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 acquires 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 generate the corresponding moving areas respectively.

The server generates a moving area at each location coordinate point according to the following formula:

the server generates a moving region corresponding to the positioning coordinate point at the (dot _ sum-1) th position from the positioning number n — dot _ sum-1, then generates a moving region corresponding to the positioning coordinate point at the (dot _ sum-2) th position, and so on until a moving region corresponding to the positioning coordinate point at the 0 th position is generated, as shown by a moving region 61 in fig. 10. In the embodiment of the application, the moving area indicates an area where a terminal corresponding to a user account meeting the article searching condition is located when the terminal moves, that is, other users may exist around the terminal in the moving process of the first user, and the server uses the other users around the first user as candidates for receiving article searching information by defining an area. In the embodiments of the present application, the moving area is a circle. The user account number meeting the article searching condition comprises a user account number with a friend relationship or a user account number without the friend relationship with the first user account.

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

The server cuts 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 cutting lines between the moving areas corresponding to the adjacent positioning numbers until the moving areas in the first time interval are connected by the cutting lines; the search area is formed according to the moving area connected by the tangent line.

As shown in fig. 11, the closed figure formed by the tangent 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 case where the distance between two positioning coordinate points is close, and the moving areas corresponding to the two positioning coordinate points are also close, so that one moving area completely contains the other moving area, as shown in fig. 12. In this case, the server may create a new moving area for the two moving areas, where the center of the new moving area is the end point of the connection line of the two positioning coordinate points, and the radius is the sum of the radii of the two circular areas. If the newly created moving area still contains other moving areas completely, the above process of creating moving areas is repeated until other moving areas are not contained completely. When the moving area does not completely include other moving areas, a tangent line is drawn between the two moving areas in a direction in which the positioning numbers of the positioning coordinate points are in descending order, for example, a tangent line is drawn from the moving area at n-5 to the moving area at n-4, a tangent line is drawn from the moving area at n-3 to the moving area at n-2, and so on.

And step 804, the server marks the user accounts meeting the object searching conditions.

The server determines a marked user account from the searching area, and 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 located in the searching area and meets the object searching conditions, 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 object searching information to the first user account, and the second user account is used for sending object positioning information of a target object to the first user account according to the received object searching information. The target item is an item determined when the terminal corresponding to the first user account receives the first selection operation.

The user account meeting the article searching condition comprises a user account having a friend relationship with the first user account, for example, the server determines the user account having the friend relationship with the first user account from the searching area, and uses the user account as the user account meeting the article searching condition.

And the user accounts meeting the article searching condition comprise user accounts which do not have a friend relationship with the first user account and have a distance from the terminal corresponding to the first user account to be less than a preset distance (such as 500 meters), and then the user accounts are used as the user accounts meeting the article searching condition.

And the user accounts meeting the object searching conditions comprise user accounts which do not have friend relationship with the first user account and are positioned in the moving area with the largest area for a time exceeding a preset threshold value, and the user accounts are used as the user accounts meeting the object searching conditions. For example, as shown in fig. 10, if the area of the corresponding moving area is the largest when n is 5, the user account located in the moving area and having a duration exceeding a preset threshold (e.g., 3 hours) is taken as the user account meeting the article-seeking condition.

And the server marks the user account which meets the object searching condition to obtain a marked user account. In some embodiments, the social application will close the seek request if the originator does not close the seek request within a valid time after initiating the seek request.

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

Step 806, displaying an account recommendation list by the terminal corresponding to the first user account.

And when the target object is found, the second user account sends object finding success information to the first user account, wherein the object finding success information is used for representing information sent when the target object is found successfully. In some embodiments, the first user account sends the information of successful finding of the object to the server, and the server records the finding process of the target object after receiving the information of successful finding of the object sent by the first user account.

In summary, in the method of this embodiment, the server generates, according to the moving path corresponding to the first user account, a search area where the target item may be located, so as to determine the user account meeting the object-finding condition where the moving track is located in the search area, screen out, from the user accounts meeting the object-finding condition, the user account meeting the object-finding condition, which has an account relationship with the first user account, and perform tagging, so that the account recommended by the server to the first user account according to the moving path better meets the user's requirements, the probability of finding the target item is increased, and the efficiency of finding the target item is improved.

The server sequentially generates moving areas according to positioning coordinate points in a moving path corresponding to the first user account, so that areas where the target object possibly exists are represented through the moving areas, the moving areas are associated with moving ranges corresponding to user accounts meeting the object finding conditions, the areas where the target object possibly exists are determined to be associated with the user accounts, and object finding information is further sent to the user accounts. The probability of finding the target object is increased, and the finding 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 moving area is larger when the probability of finding the target object is larger, the time when the user finds that the target object is lost is taken as the time when the probability of losing 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 moving areas are sequentially generated by the positioning coordinate points far away from the time, so that the moving area can accurately represent the probability of losing the object, and the user can be ensured to send object searching information to more other users.

The server screens the users who may provide help based on the search area, and the whereabouts data of the users who provide help is not sent to the users who are helped, so that the privacy of the users who provide help is protected.

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

In some embodiments, the server obtains the positioning coordinate point 131 at the moment when the first user finds that the item is lost, calculates a moving radius 132 two hours ahead from the moment (the moving distance of two hours is 8 kilometers when the walking speed of the person is 4 kilometers per hour), for example, the moment when the first user finds that the item is lost is zero-five minutes in ten hours in the morning and is eight-zero-five minutes in two hours ahead. The server makes a circle (search area) with the positioning coordinate point 131 as the center of the circle, and uses the user account in the circle area as the user account meeting the object searching condition, as shown in fig. 13. In other embodiments, the circle (search area) is made in the above manner, and the user account located in the search area for more than 90 minutes is used as the user account meeting the object-finding condition.

In some embodiments, the time when the first user finds that the item is lost is taken as a criterion, the server obtains the first positioning coordinate point 141 at the time, and when the server determines that the first user is located at the first positioning coordinate point 141, the server determines the first number of users around, where the distance 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 the second positioning coordinate point 142 corresponding to the closest time to the first positioning coordinate point 141, and determines the second user number of the surrounding users when the first user is located at the second positioning coordinate point 142. A circle 1 (first radius R1) is drawn for the first position coordinate point 141 and a circle 2 (second radius R2) is drawn for the second position coordinate point 142. Comparing the first number of users with the second number of users, and if the first number of users is greater than the second number of users, then R1 is less than R2; if the first number of users is less than the second number of users, then R1 is greater than R2. When the number of users around the first user is small, the range of the search area needs to be expanded, so that more users are ensured to be used as alternative users meeting the object searching condition. Similarly, a tangent line is drawn between two circles to form a search area, as shown in fig. 14 (a) and 14 (b). Illustratively, the user account meeting at least one of the following conditions is taken as the user account meeting the article seeking condition: the user account number which has friend relationship with the first user account number in the searching area, the user account number which has distance with the first user account number less than preset distance in the searching area, the user account number which is located in the searching area and has time exceeding a time threshold value, and the user account number which has no friend relationship with the first user account number in the searching area.

The following description is provided for the case where the method is applied to object finding by a stranger in the embodiment of the present application. If the friend range is too small to meet the object searching requirement, the object searching crowd can be properly expanded to the non-friend crowd, and the crowd can be divided into the following three priorities.

First, in conjunction with the "people nearby" function, strangers near user A will be the first priority when user A initiates a seek request. Secondly, all people in X hours before the lost article are taken as alternatives, different levels are divided according to the time length of the user appearing in the area (a circle with the radius of 1 kilometer), the area with the appearance time length exceeding 5 hours is taken as a key area, and when the user A initiates a search request, people in the area are taken as a second priority. Thirdly, in the alternative users after the previous two-level screening, different levels are also classified according to the time length of the user appearing in the area (a circle with the radius of 1 kilometer), the area with the appearance time length more than 2 hours and less than 5 hours is used as a secondary important area, and when the user A initiates an object searching request, people in the area are used as a third priority.
