Detailed Description
The embodiment of the invention provides a terminal positioning method and a terminal with an electronic compass, which can display another terminal on the electronic compass on a screen of the terminal to indicate the direction relationship between the other terminal and the terminal, further indicate the distance from the other terminal to the terminal, and enable the one terminal to track the other terminal in real time when the positions of the two terminals are changed. The following embodiments will describe the above technical solutions provided by the embodiments of the present invention in detail.
Referring to fig. 3, an embodiment of the present invention provides a terminal positioning method, which includes:
301. the first terminal controls the electronic compass to enable a pointer in the electronic compass to point to a preset direction when the pointer is mapped to the horizontal plane.
Wherein, the pointer in the step can be a compass or a compass; if it is a north arrow, the corresponding predetermined direction is the magnetic north direction; if a compass is used, the corresponding predetermined direction is the south direction of the magnetic field.
The electronic compass controlled in this step includes, but is not limited to, the following two modes: the first mode is as follows: and controlling the whole electronic compass to rotate, so that the pointer points to a preset direction when the rotated electronic compass is mapped to the horizontal plane. The second way is: and controlling the pointer in the electronic compass to rotate so that the rotated pointer points to a preset direction when being mapped to the horizontal plane. The first mode can be suitable for an electronic compass with scales and direction information indication, and can also be suitable for an electronic compass without scales and direction information indication; the second approach is only applicable to electronic compasses without scale and directional information indication. Where the scale is shown as 10, 20, 30.. 350, etc. as shown in fig. 6, and the direction information indicates ne, se, sw, nw as shown in fig. 6, where n represents north, s represents south, w represents west, and e represents east.
302. The first terminal acquires an azimuth angle of a connecting line from the first terminal to the second terminal.
In an embodiment, an azimuth angle of a connection line from a first terminal to a second terminal is a magnetic azimuth angle of the connection line, specifically, a horizontal included angle from a first standard direction of a starting point of the connection line to the connection line in a clockwise direction, where the starting point of the connection line is the first terminal, and the first standard direction is the predetermined direction, that is, a magnetic field south direction or a magnetic field north direction. Specifically, a magnetic azimuth angle of a connection line from the first terminal to the second terminal is equal to a coordinate azimuth angle of the connection line from the first terminal to the second terminal and a magnetic declination angle of a position of the first terminal, wherein the coordinate azimuth angle of the connection line from the first terminal to the second terminal is a horizontal included angle from a second standard direction of a starting point of the connection line to the connection line along an anticlockwise direction, and a coordinate system of the coordinate azimuth angle is that an equator is taken as an x axis and a 0-degree meridian is taken as a y axis. Wherein, the positive direction of the y axis points to the north latitude direction, and the positive direction of the x axis points to the east longitude direction. If the pointer in step 301 is a north pointer and the corresponding predetermined direction is a magnetic north direction, then the second standard direction is a y-axis positive direction, and if the pointer in step 301 is a south pointer and the corresponding predetermined direction is a magnetic south direction, then the second standard direction is a y-axis negative direction. The magnetic declination is an included angle between the north and the true north when the north needle is static, wherein the north is deviated to the east so that the magnetic declination is positive, and the north is deviated to the west so that the magnetic declination is negative.
In another embodiment, an azimuth angle of a connection line from the first terminal to the second terminal is a coordinate azimuth angle of the connection line, wherein the definition of the coordinate azimuth angle is the same as that in the above embodiment, and is not described herein again. That is, in this other embodiment, the declination is ignored, because the declination in our country can be up to 6 degrees at most, typically 2-3 degrees, and the declination can be ignored overall.
In one embodiment, the first terminal calculates the azimuth (i.e., the magnetic azimuth or the coordinate azimuth), and at this time, the first terminal needs to obtain the location information of the second terminal, and then determines a connection line 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, so as to determine the azimuth of the connection line. Alternatively, the first terminal may receive the azimuth angle (i.e., the magnetic azimuth angle or the coordinate azimuth angle) from the control center server, i.e., the control center server performs the above-mentioned process of calculating the azimuth angle. In another embodiment, the control center server may calculate a coordinate azimuth angle and send the coordinate azimuth angle to the first terminal, and the first terminal adds the coordinate azimuth angle and the declination angle to obtain a declination angle.
303. The first terminal displays the second terminal on the electronic compass in a direction shifted clockwise from the direction pointed by the pointer by the azimuth angle.
And displaying the second terminal in the direction which is shifted by the azimuth angle clockwise from the direction pointed by the pointer indicates the directional relation between the second terminal and the first terminal, namely which direction the second terminal is in from the first terminal, such as front or back.
In order to represent the distance between the second terminal and the first terminal while representing the directional relationship between the two terminals on the electronic compass, the following method may be specifically adopted in the step: the first terminal displays the second terminal on the electronic compass at a position which is a specific distance away from an origin in a direction which is clockwise offset from the azimuth (namely, a magnetic azimuth or a coordinate azimuth) from the direction pointed by the pointer, wherein the origin is a mapping point of the first terminal in the electronic compass, specifically, the origin may be a center of the electronic compass, and the specific distance is a distance on the electronic compass corresponding to a physical distance from the first terminal to the second terminal.
Specifically, if the pointer in step 301 is a compass, the first terminal may display the second terminal on the rotated electronic compass in a direction that is offset clockwise from the north direction of the compass by the azimuth angle. If the distance between the second terminal and the first terminal is required to be represented while the direction relationship between the second terminal and the first terminal is required to be represented on the electronic compass, the second terminal is displayed on the rotated electronic compass at a position which is away from the origin by a specific distance in the direction of clockwise shifting the azimuth from the north direction of the compass, wherein the definition of the origin and the specific distance is the same as that described above, and the description is omitted here.
Wherein, the distance on the electronic compass corresponding to the physical distance from the first terminal to the second terminal may be calculated by the first terminal itself, and before the step, to calculate the distance on the electronic compass corresponding to the physical distance from the first terminal to the second terminal, the method further includes: the first terminal receives the location information of the second 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 a distance on the electronic compass corresponding to the physical distance from the first terminal to the second terminal, wherein the specific calculation process refers to the detailed description of the subsequent embodiments. In this embodiment, the manner in which the first terminal receives the location information of the second terminal may be 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 embodiment, the distance on the electronic compass corresponding to the physical distance from the first terminal to the second terminal is sent to the first terminal by the control center server, that is, the control center server performs the calculation process. Optionally, in another embodiment, the control center server sends the physical distance from the first terminal to the second terminal to the first terminal, and the first terminal determines the distance on the electronic compass corresponding to the physical distance, so that the workload of the terminal can be reduced.
The first terminal and/or the second terminal in the embodiment of the invention are/is a movable terminal.
The first terminal controls the electronic compass to enable a pointer in the electronic compass to point to a preset direction when the pointer is mapped to a horizontal plane, and then the second terminal is displayed in a direction which is shifted by a certain azimuth angle clockwise from the direction pointed by the pointer on the electronic compass, wherein the azimuth angle is a magnetic azimuth angle or a coordinate azimuth angle of a connecting line of the first terminal to the second terminal, so that the direction relation between the second terminal and the first terminal can be displayed on the electronic compass of the first terminal, namely whether the second terminal is in front of or behind the first terminal. Furthermore, the direction relationship between the second terminal and the first terminal can be displayed on the electronic compass, and the distance between the second terminal and the first terminal can be displayed, so that the first terminal can track the second terminal in real time even if the positions of the two terminals are changed.
Referring to fig. 4, another embodiment of the present invention provides a terminal positioning method, which includes:
401. the first terminal acquires the position information of the second terminal from the control center server.
The location information of the second terminal may be a GPS coordinate of the second terminal, and the GPS coordinate includes two parameters, namely longitude and latitude.
Before this step, the second terminal needs to upload the GPS coordinates of the second terminal to the control center server. When the terminal is in a certain area, the terminal collects satellite positioning data to obtain a GPS coordinate of the terminal, and then uploads the GPS coordinate to the control center server, and specifically, the GPS coordinate of the terminal may be uploaded to the control center server through a General Packet Radio Service (GPRS) technology or WIFI or a dedicated communication network.
In one embodiment, the control center server issues 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, and the second terminal and the first terminal belong to the same group, so the GPS coordinates issued 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, and 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, and the control center server sends the GPS coordinates of the second terminal to the first terminal, so that the information storage amount of the first terminal may be reduced.
402. The first terminal obtains the angle that the electronic compass should rotate, namely the heading angle of the first terminal.
Specifically, the first terminal comprises a three-axis sensor, three axial directions of the three-axis sensor are an x axis, a y axis and a z axis, the x axis is perpendicular to the y axis, a plane formed by the x axis and the y axis is parallel to a screen of the terminal, the direction of the x axis points to the top of the terminal from the bottom of the terminal, the direction of the y axis points to the right end of the terminal from the left end of the terminal, and the z axis is perpendicular to the screen of the terminal. When the terminal is obliquely placed in the air, the measurement data output by the three-axis sensor are respectively XM、YMAnd ZMThen substituting the formula to obtain HYAnd HX：
HY＝YMcos(θ)+XMsin(θ)sin(Φ)-ZMcos(Φ)sin(θ)
HX＝XMcos(Φ)+ZMsin(Φ)
Wherein phi is an included angle between an x axis and a horizontal plane, and theta is an included angle between a y axis and the horizontal plane.
Then according toH is describedYAnd HXAnd obtaining the course angle of the first terminal.
The above only illustrates a way of calculating the first terminal course angle, and other methods of calculating the first terminal course angle may be adopted without affecting the implementation of the present invention.
403. And the first terminal rotates the electronic compass by the angle, so that the compass points to the north of the magnetic field when the rotated electronic compass is mapped to the horizontal plane.
404. And the first terminal calculates the magnetic azimuth angle of a connecting line from the first terminal to the second terminal according to the position information of the first terminal and the position information of the second terminal.
Specifically, according to the position information of the first terminal, the abscissa X of the first terminal in the coordinate system is obtained1And ordinate Y1(ii) a According to the position information of the second terminal, acquiring an abscissa X of the second terminal in a coordinate system2And ordinate Y2(ii) a The coordinate system takes the equator as an X axis, the 0-degree meridian as a Y axis, and the intersection point of the equator and the 0-degree meridian is the origin of the coordinate system; then, according to the abscissa and the ordinate of the first terminal in the coordinate system, and the abscissa and the ordinate of the second terminal in the coordinate system, a rotation angle of a connecting line from the first terminal to the second terminal in the clockwise direction relative to a standard direction of the first terminal is calculated, where the standard direction of the first terminal is parallel to the Y-axis, and the rotation angle is a coordinate azimuth angle of the connecting line from the first terminal to the second terminal, and specifically, the coordinate azimuth angle may be calculated by using the following formula:
|X1|±|X2|＝X；
|Y1|±|Y2|＝Y；
if the first terminal and the second terminal are positioned in the same quadrant, subtracting the sign, and if the first terminal and the second terminal are positioned in different quadrants, adding the sign;
when X > 0Y > 0, alpha is 90- | artan (Y/X) |;
when X is less than 0Y and more than 0, alpha is 360- | artan (Y/X) |;
when X < 0Y < 0, alpha is 180+ | artan (Y/X) |;
when X > 0Y < 0, alpha is 180- | artan (Y/X) |;
wherein α is a coordinate azimuth of a connecting line from the first terminal to the second terminal.
And then the first terminal adds the coordinate azimuth angle and the local magnetic declination to obtain a magnetic azimuth angle.
405. The first terminal calculates the physical distance from the first terminal to the second terminal according to the position information of the first terminal and the position information of the second terminal, and determines the distance on the electronic compass corresponding to the physical distance from the first terminal to the second terminal.
Specifically, the on-screen distance corresponding to the physical distance from the first terminal to the second terminal is determined according to a proportional relation between the actual unit physical distance and the on-screen unit distance, and if the on-screen unit distance is a pixel pitch and a ratio of the actual unit physical distance to the on-screen unit distance is S, the step determines that the on-screen distance corresponding to the physical distance from the first terminal to the second terminal is N pixel pitches, where N is L/S, and L represents the physical distance from the first terminal to the second terminal.
406. The first terminal displays the second terminal at a position that is shifted clockwise from the north of the compass by the magnetic azimuth angle from the origin that is the center of the electronic compass, which is the distance determined in step 405.
In this embodiment, the center of the electronic compass represents the location of the first terminal, and the location of the second terminal from the origin as the distance determined in step 405 in the direction of the north-pointing direction of the compass shifted clockwise by the magnetic azimuth angle represents the location of the second terminal, so that the direction of the second terminal relative to the first terminal and the distance of the second terminal relative to the first terminal can be represented.
In the embodiment of the invention, the first terminal rotates the electronic compass, the compass points to the magnetic field north when the rotated electronic compass is mapped to the horizontal plane, then the second terminal is displayed at the position which is away from the center of the electronic compass by the distance determined in the step 405 in the direction of clockwise deviation of the magnetic azimuth from the compass north direction after the compass rotates, so that the direction relation and the distance between the second terminal and the first terminal can be displayed on the electronic compass, and the user of the first terminal can know the position of the user of the second terminal relative to the user, the front or the back of the user and the distance from the user. Thus, even if the positions of the two terminals are changed, the first terminal can track the other terminal in real time. Furthermore, the first terminal acquires the position information of the second terminal through the control center server, and the first terminal does not need to be in direct communication with the second terminal, so that the position of the second terminal can be displayed on the electronic compass of the first terminal no matter how far the second terminal is away from the first terminal and whether the second terminal and the first terminal are connected to the same network.
