Description

The present invention relates to a mobile terminal, a control method for a mobile terminal, and a control program.

Up until now, mobile communication carriers have used mobile terminals equipped with geomagnetic sensors to check the direction of antennas when installing antennas (for example, see Patent Document 1).

The mobile terminal described in Patent Document 1 is configured to display the average shooting orientation acquired within a specified time on the display screen, improving the visibility of the display of the measurement results of the orientation in which the mobile terminal is pointed.

However, with conventional mobile terminals, the azimuth angle was calculated based only on the position of the mobile terminal placed near the installed antenna, which meant that it took a certain amount of time for the azimuth angle to stabilize.

However, please note that the technical scope of the present invention is not limited to these embodiments, but extends to the inventions described in the claims and their equivalents.

(Outline of azimuth angle measurement procedure)
A procedure for measuring the azimuth angle of a specific facility using a mobile terminal according to an embodiment of the present disclosure will be described. Here, an example of measuring the azimuth angle of an antenna 100 as the specific facility will be described. However, the present disclosure is not limited to this example, and the mobile terminal according to an embodiment of the present disclosure can be used for facilities other than antennas that are arranged facing a specific direction.

Figures 1(a) and (b) show schematic diagrams outlining a method for measuring the azimuth angle of a given facility using a mobile terminal according to one embodiment of the present disclosure. Figure 1(a) shows a schematic diagram of an image of an antenna 100 and a target 31 captured using a mobile terminal 10, and Figure 1(b) shows an example of the captured image displayed on the display unit 8 of the mobile terminal 10.

The mobile terminal 10 can capture images of the antenna 100 and the target object 31 using an imaging unit (not shown). The antenna 100 needs to be installed facing a specific direction, and the person installing the antenna 100 needs to leave a record that the antenna 100 is installed facing the specific direction. The outer surface of the antenna 100 may be provided with a sign 101 indicating the direction of the antenna 100. In this case, the person installing the antenna 100 can measure the azimuth angle of the antenna 100 by measuring the azimuth angle of the sign 101.

The mobile terminal 10 can display on the display unit 8 a reference line 20 that intersects with the optical axis of the lens of the imaging unit and extends vertically to the ground. The mobile terminal 10 can also display an azimuth angle, which is the angle of the reference line 20 from true north, by the intersection of the reference line 20 and a compass 24. Note that, as shown in FIG. 1(b), an azimuth angle 22 may be displayed on the display unit 8. A method for measuring the azimuth angle will be described later.

When the mobile terminal 10 captures the sign 101 of the antenna 100 and the building 300, the display unit 8 displays the building 300 beyond the sign 101, as shown in FIG. 1B. It is assumed that the target 31 installed on the building 30 is located on the extension of the direction of the antenna 100 in this building 300. In this case, the azimuth angle 22 of the reference line 20 in the state in which the target 31 is projected on the extension of the sign 101 of the antenna 100 coincides with the azimuth angle of the antenna 100. In this way, the azimuth angle when the sign 101 indicating a specific direction attached to the antenna 100, which is a specific facility captured by the imaging unit, and the reference line 20 are aligned can be regarded as the azimuth angle of the specific facility (antenna). Note that the target 31 does not necessarily have to be installed on the building 30. In this case, the building 30 itself may be the target. Also, even if the target 31 is installed on the building 30, the building 30 itself may be the target. In other words, the target is not limited to a target 31 installed on the building 30, but the building 30 itself may be used as the target.

Specifically, when the intersection point X between the reference line 20 and the horizontal line 21 is placed on the target 31, the reference line 20 overlaps with the sign 101 of the antenna 100, and the azimuth angle 22 of the reference line 20 at this time becomes the azimuth angle of the antenna 100.

The mobile terminal 10 may also display, on the display unit 8, a compass 24 that displays the azimuth angle, superimposed on the image captured by the imaging unit. The compass 24 shows the azimuth angle when true north is set to 0 degrees. By displaying the compass 24 on the display unit 8 superimposed on the image captured by the imaging unit, it is possible to confirm that the target 31 overlaps with the reference line 20. If the positions of the target 31 and the reference line 20 are misaligned, the equipment installation worker adjusts the orientation of the imaging unit so that the target 31 overlaps with the reference line 20.

Therefore, by capturing an image in the state shown in FIG. 1(b), it is possible to record that the azimuth angle of the antenna 100 is set to a predetermined angle of, for example, 40 degrees. For example, the equipment installer may use the screenshot function of the mobile terminal 10 to capture and save an image of the display unit 8. At this time, an image may be recorded in which the equipment identification number and information regarding the latitude and longitude of the current location are displayed on the display unit 8.

(Mobile terminal configuration)
2 shows a configuration block diagram of a mobile terminal 10 according to an embodiment of the present disclosure. The mobile terminal 10 includes a control unit 4, a transmission unit 5, a reception unit 6, and an output unit 7, which are connected via an internal bus 14. The mobile terminal 10 may further include a display unit 8, an imaging unit 9, a GPS unit 11, a storage unit 12, an input unit 13, and a gyro sensor 15.

The mobile terminal 10 may be, for example, a multi-function mobile phone. However, it is not limited to such an example, and the mobile terminal 10 may be a mobile phone such as a feature phone, a personal digital assistant such as a PDA, a tablet terminal, a tablet PC, a notebook PC, etc.

The transmitter 5 and receiver 6 are equipped with a communication interface circuit including an antenna sensitive to a specific frequency band, and connect the mobile terminal 10 to a network such as the Internet. The transmitter 5 and receiver 6 establish a radio signal line using a CDMA system or the like with the base station via a channel assigned by the base station, and communicate with the base station. The transmitter 5 and receiver 6 then transmit data supplied from the controller 4 to an external device such as a server. The transmitter 5 and receiver 6 also supply data received from the external device to the controller 4.

The output unit 7 outputs the data acquired from the control unit 4 to the display unit 8. The output unit 7 may convert the data acquired from the control unit 4 into an audio signal or the like and output it to a speaker (not shown) or the like.

The display unit 8 may be any device capable of outputting moving images, still images, etc., and may be, for example, a touch panel display device, a liquid crystal display, an organic EL display, etc. The display unit 8 can display moving images corresponding to moving image data supplied from the control unit 4, still images corresponding to still image data, etc.

The imaging unit 9 is a digital camera device or video camera device that captures an image from the front surface of the display unit 8 that displays various information in the direction of the back surface of the display screen. For example, the imaging unit 9 is installed on the back surface of the display unit 8 in a housing having the display unit 8 of the mobile terminal 10, and acquires image information captured at each predetermined capture time. In this way, the imaging unit 9 can capture images of the surroundings of the mobile terminal 10. The acquired image information can be displayed on the display unit 8 each time it is acquired.

The input unit 13 may be any device capable of inputting information to the mobile terminal 10, such as a touch panel or key buttons. A user can use the input unit 13 to input letters, numbers, symbols, etc. When operated by a user, the input unit 13 generates a signal corresponding to the operation. The generated signal is then supplied to the control unit 4 as an instruction from the user.

The control unit 4 includes a current location information acquisition unit 1 and a target location information acquisition unit 2. The control unit 4 may further include a correction unit 3. These components of the control unit 4 may be functional modules realized by a program executed by a processor included in the control unit 4. Alternatively, these components included in the control unit 4 may be implemented in the mobile terminal 10 as firmware.

The current location information acquisition unit 1 acquires location information of the current location. To this end, the mobile terminal 10 includes a GPS (Global Positioning System) unit 11, and the current location information acquisition unit 1 may acquire location information of the current location of the mobile terminal 10 from the GPS unit 11. However, the present invention is not limited to this example, and as described below, the current location information acquisition unit 1 may acquire location information of the current location by setting the current location on a map linked to the location information. Here, the location information of the current location may be the latitude and longitude of the current location acquired from the GPS unit, or may be values obtained by converting the latitude and longitude values into planar rectangular coordinates.

The GPS unit 11 has a GPS circuit including an antenna that is mainly sensitive to the 1.5 GHz band, and receives GPS signals from GPS satellites. The GPS unit 11 decodes the GPS signals and acquires time information, etc. Next, the GPS unit 11 calculates the pseudo distance from the GPS satellite to the mobile terminal 10 based on the time information, etc., and detects the location (latitude, longitude, altitude, etc.) of the mobile terminal 10 by solving simultaneous equations obtained by substituting the pseudo distance. The GPS unit 11 then associates position information indicating the detected position with the acquired position and time information, and outputs them at each specified GPS output time. The specified GPS output time may be any time, for example, 1/10 second, 1/5 second, 1/2 second, etc.

The target position information acquisition unit 2 acquires position information of a target point on a map. Figures 3(a) and (b) show display examples when a current point and a target point are displayed on a map using a mobile terminal according to an embodiment of the present disclosure. Figure 3(a) shows an example in which a current point _P0 is displayed on a map displayed on the display unit 8 of the mobile terminal 10. Figure 3(b) shows an example in which a current point _P0 and a target point _Pt are displayed on a map displayed on the display unit 8 of the mobile terminal 10.

The storage unit 12 stores the location information of the current location acquired by the current location information acquisition unit 1 and the location information of the target location acquired by the target location information acquisition unit 2. The storage unit 12 may be, for example, a semiconductor memory device such as a ROM or a RAM. The storage unit 12 may store an operating system program, a driver program, an application program, data, etc. used for processing in the control unit 4. For example, the storage unit 12 stores, as driver programs, an input device driver program that controls the input unit 13, an output device driver program that controls the display unit 8, etc. The storage unit 12 also stores, as application programs, programs that display images, etc.

3B, since the azimuth angle θ measured from the true north direction A _-N of the antenna 100 is equal to the direction of the antenna 100, an arbitrary point on an extension line of an arrow A pointing in the direction of the azimuth angle θ from the current point P _-0 is set as a target point P _-t . The position information of the target point P- _t may be latitude and longitude obtained by touching the map displayed on the display unit 8, or may be a value obtained by converting the latitude and longitude values into planar rectangular coordinates.

Here, the display unit 8 may display a range on the map that is a predetermined distance from the current point _P0 as a range that cannot be set as the target point _Pt . That is, if the target point _Pt is too close to the current point _P0 , it is difficult to adjust the azimuth angle θ, so it is preferable not to set the target point _Pt in the area ₂₀₀ around the current point P0. For example, the area 200 may be a circular area with a radius of a predetermined distance from the current point _P0 . However, the shape of the area 200 is not limited to this example, and may be any shape.

The method of inputting the location information of the destination point is not limited to tapping a specific position on the map, but may be executed by inputting the name of the facility or the like of the destination point into the application software. For example, if the destination point is "Tokyo Tower," the location information of "Tokyo Tower" may be obtained by inputting the characters "Tokyo Tower." Alternatively, voice input may be used instead of character input.

(How to determine the azimuth angle)
Next, a method for acquiring the azimuth angle of the antenna 100 using a mobile terminal according to an embodiment of the present disclosure will be described. The transmitter 5 of the mobile terminal 10 transmits the location information of the current location acquired from the current location information acquisition unit 1 and the location information of the target location acquired from the target location information acquisition unit 2 to a direction information agency. The direction information agency may be, for example, a website of the Geospatial Information Authority of Japan on the Internet. However, the direction information agency is not limited to this example and may be any website that can calculate the azimuth angle from the location information.

Figure 4 shows an example of a data input screen of a location information agency that has transmitted location information from a mobile device according to an embodiment of the present disclosure. For example, a table 400 such as that shown in Figure 4 is displayed on the Geospatial Information Authority of Japan's website. In the first column 401, the method of inputting coordinate values can be set to either inputting the coordinate values numerically or selecting them on a map. The location information is transmitted from the mobile device using an API (Application Programming Interface) provided by the location information agency's website, so no input is required via an input screen.

The second column 402 indicates that GRS80 (Geodetic Reference System 1980) is used as the ellipsoid model of the Earth in geodesy. GRS80 is one of the reference ellipsoids that make up the global geodetic system, and is currently the most widely used worldwide.

In the third column 403, you can select whether or not to confirm the coordinate values entered in the fourth column 404 and the fifth column 405 on the map, and whether or not to clear the coordinates displayed on the map.

In a fourth field 404, the latitude and longitude values acquired by the current position information acquisition unit 1 are input as the position information of the current point _P0 . Similarly, in a fifth field 405, the latitude and longitude values are input as the position information of the target point _Pt acquired by the target position information acquisition unit 2.

The sixth column 406 allows you to select whether the units of the data entered in the fourth column 404 and the fifth column 405 are degrees, minutes, and seconds, or the decimal system. Here, we will explain an example in which the units are degrees, minutes, and seconds.

When the coordinates of the current point _P0 and the target point _Pt are input into the table 400 shown in FIG. 4 and an azimuth angle calculation is executed, the azimuth angle from the current point _P0 to the target point _Pt is calculated. FIGS. 5(a) and (b) show an example of a display screen of the calculation result of the azimuth angle in the location information agency that transmitted the location information from the mobile terminal 10 according to an embodiment of the present disclosure. FIG. 5(a) shows a table 500 showing the latitude and longitude values of the current point _P0 and the target point _Pt input in the table 400 shown in FIG. 4. The latitude and longitude of the current point _P0 displayed in the seventh column 501 is the same as the value input in the fourth column 404 of FIG. 4, and the latitude and longitude of the target point _Pt displayed in the eighth column 502 is the same as the value input in the fifth column 405 of FIG. 4. FIG. 5B shows a table 600 indicating the geodesic length d (601) and azimuth angle θ (602) calculated from the input latitude and longitude values of the current point and the latitude and longitude values of the target point.

In the example shown in FIG. 5(b), the geodesic length d is calculated to be 1831.801 m, and the azimuth angle θ is calculated to be 40°45'04.59". The receiver 6 receives information (e.g., 40 degrees) about the azimuth angle θ from the current location to the target location, which is calculated based on the position information of the current location and the target location, from a direction information agency (e.g., the Geospatial Information Authority of Japan).

The output unit 7 outputs information related to the received azimuth angle θ. For example, as shown in FIG. 1(b), the output unit 7 may display the azimuth angle "40 degrees" in the azimuth angle display section 22 of the display unit 8.

(Operation flow of direction measurement process)
Next, a procedure for determining an azimuth angle by a mobile terminal according to an embodiment of the present disclosure will be described. Fig. 6 shows a flowchart for explaining a procedure for determining an azimuth angle by using a mobile terminal according to an embodiment of the present disclosure.

First, in step S101, the current location information acquisition unit 1 acquires location information of the current location of the mobile terminal 10. The current location information acquisition unit 1 can acquire location information (e.g., latitude and longitude) of the current location of the mobile terminal 10 using the GPS unit 11. The control unit 4 may store the location information of the current location of the mobile terminal 10 acquired by the current location information acquisition unit 1 in the storage unit 12.

Next, in step S102, the target position information acquisition unit 2 acquires position information of the target point on the map. Specifically, as shown in FIG. 3B, the user taps the position of the target point _Pt on the map displayed on the display unit 8 to acquire position information (e.g., latitude and longitude) of the target point _Pt . Examples of applications that can acquire position information by tapping a specific position on the map include, but are not limited to, Google Maps (registered trademark) and Maps by Apple.

Next, in step S103, the transmitting unit 5 transmits the position information of the current point P0 and the position information of the target point _Pt acquired by the current position information acquiring unit ₁ and the target position information acquiring unit 2 to the direction information agency. The direction information agency is, for example, the Geospatial Information Authority of Japan site, but is not limited to such an example. For example, on the Geospatial Information Authority of Japan site, as shown in table 400 in FIG. 4, the latitude and longitude data of the current point _P0 is input in the fourth column 404 as the position information of the current point _P0 , and the latitude and longitude data of the target point _Pt is input in the fifth column 405 as the position information of the target point _Pt , and calculation is performed. As a result, as shown in FIG. 5B, the geodesic length d between the current point _P0 and the target point _Pt and the azimuth angle θ from the current point _P0 to the target point _Pt are calculated as output points.

Next, in step S104, the receiving unit receives information about the azimuth angle from the current point _P0 to the target point _Pt , which is calculated based on the position information of the current point _P0 and the target point _Pt, from the site of the Geospatial Information Authority of Japan, which is a direction information organization.

Next, in step S105, the output unit 7 outputs information about the received azimuth angle θ. For example, the output unit 7 may display the azimuth angle "40 degrees" on the azimuth angle display section 22 of the display unit 8, as shown in FIG. 1(b).

(Procedure for setting true north)
As described above, the azimuth angle from the current location to the target location and the measured point length from the current location to the target location can be obtained by transmitting the location information of the current location and the target location to the direction information agency and receiving information on the azimuth angle from the current location to the target location calculated based on the location information of the current location and the target location from the direction information agency. Here, if the angle displayed on the compass 24 when the cross mark is aligned with the position of the target object 31 is to be the corrected azimuth angle, the angle display on the compass 24 needs to be accurate. Therefore, the procedure for calculating the coordinates pointing to true north from the acquired azimuth angle and measured point length, and setting the display on the compass 24 to 0 degrees when the mobile terminal 10 is pointed in the direction of true north will be described.

7 shows a flowchart for explaining a procedure for setting the true north direction of a compass based on information about an acquired azimuth angle using a mobile terminal according to an embodiment of the present disclosure. First, in step S201, the coordinates of true north are determined based on information about the azimuth angle θ. Information about the azimuth angle θ from the current point toward the target point calculated based on the position information of the current point and the target point includes the azimuth angle θ and a geodesic length d, as shown in FIG. 5B. The geodesic length d is the distance between the current point P ₀ and the target point P _t , and the azimuth angle θ is the angle based on true north in the direction from the current point P ₀ toward the target point P _t .

8 is a diagram for explaining a method for calculating the true north direction from the distance and azimuth between the current point and the target point. Since the coordinates, azimuth angle θ, and geodesic line length d of the current point _P0 and the target point _Pt are known, the coordinates of a point _PN in the true north direction can be obtained. By adjusting the compass 24 so that the display of the compass 24 is 0 degrees when the mobile terminal 10 is pointed in the direction of this point _PN , the true north direction of the compass 24 can be set. In addition, the azimuth angle of the mobile terminal 10 can be displayed as the angle at which the compass 24 and the reference line 20 intersect, using the gyro sensor 15.

Next, in step S202, the mobile device 10 is oriented toward the coordinates of true north, and the display of the compass 24 is adjusted so that the true north direction coincides with 0 degrees on the compass 24. In this manner, the true north direction can be set to 0 degrees on the compass.

(Procedure for recording the azimuth angle of installed equipment)
[First embodiment]
Next, a procedure for saving as a record that a specific facility is installed facing a specified azimuth angle will be described. As a prerequisite, the specific facility is assumed to be installed in advance facing a specified azimuth. For example, it is assumed that an antenna 100, which is a specific facility, is installed facing a specified azimuth angle (for example, 40 degrees). FIG. 9 shows a flowchart for explaining a procedure for saving as a record that a specific facility is installed facing a specified azimuth angle using a mobile terminal according to an embodiment of the present disclosure.

First, in step S301, an image of the target 31 is captured using the imaging unit 9 of the mobile terminal 10. At this time, it is preferable to capture the image so that the antenna 100 and the sign 101 are included as part of the image.

Specifically, the user aligns the position of the target 31 (or building 30) with the cross X, captures an image at that time, and saves it. In this way, the user can save as a record that a specific piece of equipment is installed facing the specified azimuth angle.

Second Embodiment
In this way, the user can record the direction in which the specified equipment is installed, but if the position of the target 31 and the position of the cross X are misaligned, the following correction may be made. Next, in step S302, it is determined whether the position of the target 31 matches the mark, the cross X. When the user taps the target point on the map, there may be a misalignment with the original position, or the position information of the target differs from the position information of the building in which the target is installed, and in such cases, there may be a difference between the azimuth angle from the current position to the target point and the azimuth angle of the installed specified equipment.

Figures 10(a) and (b) are diagrams for explaining the procedure for correcting the azimuth angle using a mobile terminal according to an embodiment of the present disclosure. Figure 10(a) shows a state in which the azimuth angle from the current location to the target location does not match the azimuth angle of antenna 100, which is a specified facility.

Here, the display unit 8 displays a mark based on the information about the azimuth angle, superimposed on the image of the surroundings of the current location. For example, the mark may be a cross X consisting of a reference line 20 and a horizontal line 21. However, the mark is not limited to this example, and may have any shape.

For example, if the user taps on a map at a location near the target 31 when in fact the user should have tapped on that location, the azimuth angle from the current location to the target 31 may not match the azimuth angle of the mobile device 10. In such a case, as shown in FIG. 10(a), a discrepancy occurs between the position of the cross X formed by the reference line 20 and the horizontal line 21 and the position of the target 31 on the display unit 8 of the mobile device 10.

Here, a compass 24 is displayed on the display unit 8, and the angle indicated by the reference line 20 on the compass 24 is the azimuth angle of the mobile device 10. FIG. 10(a) shows an example in which the target point tapped by the user is a position away from the target object 31, and for example, the azimuth angle display unit 22 displays "43 degrees." In this case, the sign 101 of the antenna 100 displayed on the display unit 8 is offset from the reference line 20, so the user can recognize that the target point set by tapping is offset from the original position of the target object 31.

If the position of the target 31 does not match the cross X mark in step S302, the direction of the mobile terminal 10 is corrected in step S303. FIG. 10(b) shows an example of the display unit 8 after the user has corrected the azimuth. The user can recognize from the image on the display unit 8 shown in FIG. 10(a) that the position of the target 31 does not match the position of the cross X mark, and so, as shown in FIG. 10(b), the user rotates the mobile terminal 10 to the left so that the position of the target 31 matches the position of the cross X. When the position of the target 31 matches the position of the cross X, the angle indicated by the reference line 20 on the compass 24 is 40 degrees.

Next, the correction unit 3 corrects the information about the azimuth angle in response to an input signal input by the user when the mark, the cross X, points in the direction of the target object 31 located at the target location. As a result, the azimuth angle displayed on the azimuth angle display unit 22 can be changed from the pre-correction value of "43 degrees" to the corrected value of "40 degrees."

Next, in step S304, an image of the target 31 and the compass 24 is recorded. In this way, it is possible to store a record that the antenna 100 is set facing the specified azimuth angle.

As described above, the mobile terminal, the control method for the mobile terminal, and the control program according to the embodiments of the present disclosure can accurately and easily measure the orientation direction of a specified facility.
