An embodiment of the present invention provides a terminal positioning method and a terminal with an electronic compass, which can display another terminal on an electronic compass on a screen of one terminal, indicating a direction relationship between the other terminal and the terminal, and further, It can indicate the distance from another terminal to the terminal, and enable one terminal to track the other terminal in real time when the positions of the two terminals change. The above technical solutions provided by the embodiments of the present invention are described in detail in the following embodiments.

Referring to FIG. 3, an embodiment of the present invention provides a terminal positioning method, including:

301. The first terminal controls the electronic compass to point the pointer in the electronic compass to a predetermined direction when mapping to a horizontal plane.

The pointer in this step may be a north arrow or a compass; if it is a north needle, the corresponding predetermined direction is the north direction of the magnetic field; if it is a compass, the corresponding predetermined direction is the south direction of the magnetic field.

The control of the electronic compass in this step includes, but is not limited to, the following two methods: The first mode is: Controlling the rotation of the entire electronic compass so that when the rotated electronic compass is mapped to the horizontal plane, the pointer points to a predetermined direction. The second way is: Control the rotation of the pointer in the electronic compass so that the rotated pointer points to the predetermined direction when it maps to the horizontal plane. Among them, the first method can be applied to an electronic compass with indication of scale and direction information, or to an electronic compass without indication of scale and direction information; the second method is only applicable to an electronic compass without indication of scale and direction information. Wherein, the scale is 10, 20, 30.....350 as shown in FIG. 6, and the direction information indicates ne, se, sw, nw as shown in FIG. 6, where n represents north and s represents south. w means west and e means east.

302. The first terminal acquires an azimuth of a connection between the first terminal and the second terminal.

Wherein, in an embodiment, the azimuth of the line connecting the first terminal to the second terminal direction is the magnetic azimuth angle of the connection, specifically, starting from the first standard direction of the starting point of the connection, clockwise a horizontal angle between the direction and the connecting line, wherein the starting point of the connecting line is the first terminal, and the first standard direction is the predetermined direction, that is, the magnetic field south direction or the magnetic field north direction. Specifically, the magnetic azimuth of the connection from the first terminal to the second terminal direction is the connection of the first terminal to the second terminal direction Coordinate azimuth + magnetic declination of the position of the first terminal, wherein the coordinate azimuth of the connection from the first terminal to the second terminal direction starts from the second standard direction of the starting point of the connection, and proceeds clockwise The horizontal angle between the lines, wherein the coordinate azimuth is located in the coordinate system with the equator as the X-axis and the 0-degree warp as the y-axis. Among them, the y-axis is pointing in the north latitude direction, and the X-axis is pointing in the east direction. If the pointer in step 301 is a north arrow, and the corresponding predetermined direction is the north direction of the magnetic field, the second standard direction is the positive direction of the y-axis. If the pointer in step 301 is a compass and the corresponding predetermined direction is the south direction of the magnetic field, then The second standard direction is the _y- axis negative direction. Among them, the magnetic declination refers to the angle between the north and the true north when the north needle is stationary. Among them, the magnetic deviation angle is positive in the north direction and the magnetic declination is negative in the west direction.

In another embodiment, the azimuth of the line connecting the first terminal to the second terminal direction is a coordinate azimuth of the connection, wherein the definition of the coordinate azimuth is the same as that in the foregoing embodiment, and is not Let me repeat. That is to say, in this other embodiment, the magnetic declination is ignored because the magnetic declination in China is up to 6 degrees, and generally 2-3 degrees, and the magnetic declination is generally negligible.

In one mode, the first terminal calculates the azimuth (ie, the magnetic azimuth or the coordinate azimuth) by itself, and the first terminal needs to acquire the location information of the second terminal, and then according to the location information of the first terminal. The location information of the second terminal determines the connection between the first terminal and the second terminal, and then determines the azimuth of the connection. For the specific calculation manner, refer to the detailed description of the subsequent embodiments. Alternatively, the first terminal can receive the azimuth (i.e., magnetic azimuth or coordinate azimuth) from the control center server, i.e., the process of calculating the azimuth by the control center server. In yet another embodiment, the control center server can calculate the coordinate azimuth and send it to the first terminal, which adds the coordinate azimuth to the magnetic declination to obtain a magnetic azimuth.

303. The first terminal displays the second terminal on the electronic compass in a direction in which the direction of the pointer is clockwise offset from the azimuth.

Displaying the second terminal in a direction in which the direction of the pointer is clockwise offset from the azimuth indicates a directional relationship between the second terminal and the first terminal, that is, the second terminal is at the first terminal. Which direction, such as front or rear.

In order to indicate the distance between the second terminal and the first terminal on the electronic compass, the step may specifically be as follows: The first terminal is on the electronic compass, clockwise in the direction indicated by the pointer Displaying the second terminal at a position offset from the origin by a certain distance in the direction of the azimuth (ie, magnetic azimuth or coordinate azimuth), the origin being the first terminal at the electronic compass The mapping point in the specific point may be the center of the electronic compass, and the specific distance is the distance on the electronic compass corresponding to the physical distance of the first terminal to the second terminal.

Specifically, if the pointer in step 301 is a north arrow, the first terminal may display the direction of the azimuth offset clockwise in the north direction of the north arrow on the rotated electronic compass. The second terminal. If the distance between the second terminal and the first terminal is indicated on the electronic compass, the distance between the two terminals is indicated, and the first terminal is clockwise shifted in the north direction of the north arrow on the rotated electronic compass. The second terminal is displayed at a position that is a certain distance from the origin in the direction of the azimuth. The definition of the origin and the specific distance is the same as the above, and details are not described herein again.

The distance on the electronic compass corresponding to the physical distance of the first terminal to the second terminal may be calculated by the first terminal itself, in order to calculate the physical compass corresponding to the physical distance of the first terminal to the second terminal. The distance, before the step, further includes: receiving, by the first terminal, location information of the second terminal, and calculating a physical distance from the first terminal to the second terminal according to the location information of the first terminal and the location information of the second terminal, determining The distance on the electronic compass corresponding to the physical distance from the first terminal to the second terminal. For the specific calculation process, refer to the detailed description of the subsequent embodiments. The location information of the first terminal may be a Global Positioning System (GPS) coordinate of the first terminal, and the location information of the second terminal may be a GPS coordinate of the second terminal. In this embodiment, the first terminal receives the first The location information of the second terminal may be obtained by directly receiving the location information of the second terminal from the second terminal, or receiving the location information of the second terminal from the control center server, that is, receiving the location information of the second terminal sent by the control center server. . Optionally, in another implementation manner, the distance on the electronic compass corresponding to the physical distance of the first terminal to the second terminal is sent by the control center server to the first terminal, that is, the foregoing calculation is performed by the control center server. the process of. Optionally, in another implementation manner, the control center server sends the physical distance of the first terminal to the second terminal to the first terminal, where the first terminal determines the distance on the electronic compass corresponding to the physical distance, such that , can reduce the workload of the terminal.

The first terminal and/or the second terminal in the embodiment of the present invention are mobile terminals.

The first terminal in the embodiment of the present invention controls the electronic compass to point the pointer in the electronic compass to a predetermined direction when mapped to the horizontal plane, and then displays the direction in the direction indicated by the pointer on the electronic compass clockwise offset by a certain azimuth. a second terminal, the azimuth is a magnetic azimuth or azimuth of a line connecting the first terminal to the second terminal, so that the second terminal and the second terminal can be displayed on the electronic compass of the first terminal The directional relationship of a terminal, that is, whether the second terminal is in front of or behind the first terminal. Further, the distance between the second terminal and the first terminal may be indicated on the electronic compass while indicating the distance between the two terminals, so that the first terminal can perform real-time on the second terminal even if the positions of the two terminals change. 3 tracks.

Because the terminal is in a certain area, it collects satellite positioning data, obtains the GPS coordinates of the terminal, and then uploads the GPS coordinates to the control center server. Specifically, it can pass the General Packet Radio Service (GPRS) technology. Or WIFI or a dedicated communication network uploads the GPS coordinates of the terminal to the control center server.

In an embodiment, the control center server sends the GPS coordinates of each terminal in the group in which the first terminal is located to the first terminal, where the group in which the first terminal is located includes all terminals belonging to the same team as the first terminal, The second terminal and the first terminal belong to the same group, so the GPS coordinates delivered by the control center server include the GPS coordinates of the second terminal. In another embodiment, the first terminal may request the control center server for the GPS coordinates of the second terminal. Specifically, the first terminal may send the phone number of the second terminal or the ID number of the second terminal to the control center server. The control center server transmits the GPS coordinates of the second terminal to the first terminal, so that the information storage amount of the first terminal can be reduced.

402. The first terminal obtains an angle at which the electronic compass should rotate, that is, a heading angle of the first terminal.

Specifically, the first terminal includes a three-axis sensor, and the three axial directions of the three-axis sensor are an X-axis, a y-axis, and a z-axis, wherein the X-axis is perpendicular to the y-axis, and the plane and the terminal formed by the X-axis and the y-axis The screens are parallel, the direction of the X-axis is from the bottom of the terminal to the top of the terminal, and the direction of the y-axis is from the left end of the terminal to the right end of the terminal, and the z-axis is perpendicular to the screen of the terminal. When the terminal is tilted in the air, the measured data output by the three-axis sensor are X _M , Y _M and Z _M , respectively, and then substituted into the following formula to find Η _γ and H _x :

H _Y =Y _M cos( Θ )+X _M sin( Θ )sin(0)-Z _M cos(0)sin( θ )

Z _M sin(O) Where Φ is the angle between the x-axis and the horizontal plane, and Θ is the angle between the y-axis and the horizontal plane. Then, according to the above Η _γ and Η _χ , the heading angle of the first terminal is obtained.

Wherein, the foregoing only illustrates a manner of calculating the heading angle of the first terminal, and other methods of calculating the heading angle of the first terminal may be employed, without affecting the implementation of the present invention.

403. The first terminal rotates the electronic compass to the above angle, so that the north compass points to the north magnetic field when the rotated electronic compass is mapped to the horizontal plane.

404. The first terminal calculates a magnetic azimuth of the connection of the direction of the first terminal to the second terminal according to the location information of the first terminal and the location information of the second terminal.

Specifically, the abscissa and the ordinate Yi of the first terminal in the coordinate system are obtained according to the location information of the first terminal; and the abscissa X ₂ and the vertical direction of the second terminal in the coordinate system are obtained according to the location information of the second terminal. Coordinate Y ₂ ; where, the coordinate system takes the equator as the X-axis, the 0-degree warp as the Υ axis, and the intersection of the equator and the 0-degree warp as the origin of the coordinate system; then the abscissa and the ordinate according to the first terminal in the coordinate system And an abscissa and an ordinate of the second terminal in the coordinate system, and calculating a rotation angle of the connection line of the first terminal to the second terminal direction in a clockwise direction with respect to a standard direction of the first terminal, wherein the embodiment The standard direction of the first terminal is parallel to the forward direction of the x-axis, and the rotation angle is the coordinate azimuth of the line connecting the first terminal to the second terminal. Specifically, the coordinate azimuth can be calculated by the following formula: | Χ1 | | Χ2 | =Χ;

| Υ1 | + | Υ2 | =Υ;

If the first terminal and the second terminal are in the same quadrant, the minus sign is taken. If the first terminal and the second terminal are in different quadrants, the plus sign is taken;

When Χ>0 Υ>0, α= 90-lartan(Y/X)l;

When X<0 Y>0, α= 360-lartan(Y/X)l;

When Χ<0 Υ<0, α= 180+lartan(Y/X)l;

When Χ>0 Υ<0, α= 180-lartan(Y/X)l;

Where α is the coordinate azimuth of the line connecting the first terminal to the second terminal direction.

The first terminal then adds the coordinate azimuth to the local magnetic declination to obtain a magnetic azimuth.

The first terminal calculates a physical distance from the first terminal to the second terminal according to the location information of the first terminal and the location information of the second terminal, and determines an electronic compass corresponding to the physical distance of the first terminal to the second terminal. the distance. Specifically, the distance on the screen corresponding to the physical distance of the first terminal to the second terminal is determined according to the actual ratio of the unit physical distance to the unit distance on the screen. If the unit distance on the screen is the pixel spacing, the actual unit physical distance The ratio of the unit distance to the screen is S, and the step determines that the distance on the screen corresponding to the physical distance of the first terminal to the second terminal is N pixel pitches, where N=L/S, L represents the first terminal to The physical distance of the second terminal.
