[0059] With the development of technology, people can use navigation software to plan routes at any time when traveling, and the travel route is displayed on the navigation interface to guide users. However, the direction indicated on the navigation interface is often not related to the direction the user is facing. For users with a weak sense of direction, they may not be able to distinguish the direction indicated by the navigation software, causing the user to get lost and a poor user experience.

[0060] To solve the above problems, the embodiments of the present invention provide a direction indication method, device, head-mounted display device, mobile terminal, system and storage medium. The head-mounted display device obtains the first longitude and latitude of the starting position and the second longitude and latitude of the destination position, and determines the target azimuth through the longitude and latitude of the starting position and the destination position, and determines the current azimuth corresponding to the user's current orientation through its own nine-axis inertial measurement unit, and then generates direction indication information according to the target azimuth and the current azimuth, and displays the direction indication information, so that the user can clearly know the relationship between the direction indicated on the navigation interface displayed by the head-mounted display device and the direction the user is facing, thereby improving the accuracy of the direction indication and avoiding users with weak sense of direction from being unable to distinguish the direction indicated by the navigation software.

[0061] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0062] See also Figure 1 , Figure 1 It is a schematic diagram of a scenario for implementing the direction indication method provided by an embodiment of the present invention.

[0063] like Figure 1 As shown, the head mounted display device 100 is connected in communication with the mobile terminal 200. The head mounted display device 100 includes a nine-axis inertial measurement unit (IMU), which includes a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetometer. The head mounted display device 100 and the mobile terminal 200 can establish a communication connection through Bluetooth or mobile wireless interconnection (wireless fidelity, wifi), and the head mounted display device 100 can include augmented reality (AR) glasses, AR helmets, mixed reality (MR) glasses, and MR helmets. The mobile terminal 200 can include a mobile phone, a tablet computer, a laptop computer, a desktop computer, a personal digital assistant, a wearable device, and the like.

[0064] When executing the direction indication method provided by the embodiment of the present invention, the mobile terminal 200 obtains the first longitude and latitude of the starting position and the second longitude and latitude of the destination position, and determines the target azimuth according to the first longitude and latitude and the second longitude and latitude; the head-mounted display device 100 determines the current azimuth corresponding to the current orientation of the user through its own nine-axis inertial measurement unit, and sends the current azimuth to the mobile terminal 200; when the mobile terminal 200 obtains the current azimuth sent by the head-mounted display device, it generates direction indication information according to the target azimuth and the current azimuth, and sends the direction indication information to the head-mounted display device 100; the head-mounted display device 100 displays the direction indication information.

[0065] In some embodiments, the mobile terminal 200 includes a nine-axis inertial measurement unit. When executing the direction indication method provided in the embodiment of the present invention, the mobile terminal 200 obtains the first longitude and latitude of the starting position and the second longitude and latitude of the destination position, and determines the target azimuth according to the first longitude and latitude and the second longitude and latitude; determines the current azimuth corresponding to the user's current orientation through the nine-axis inertial measurement unit of the mobile terminal 200 itself; generates direction indication information according to the target azimuth and the current azimuth, and displays the direction indication information. This embodiment does not require the use of other devices, and direction indication can be achieved only through the mobile terminal 200, which improves the convenience of implementing direction indication, and the user can clearly know the relationship between the direction indicated on the navigation interface and the direction the user is facing, which improves the accuracy of the direction indication and avoids the inability of users with weak sense of direction to distinguish the direction indicated by the navigation software.

[0066] In some embodiments, the head mounted display device 100 obtains a first longitude and latitude of a starting position and a second longitude and latitude of a destination position; determines a target azimuth according to the first longitude and latitude and the second longitude and latitude, determines a current azimuth corresponding to the user's current orientation through a nine-axis inertial measurement unit; generates direction indication information according to the target azimuth and the current azimuth, and displays the direction indication information. For example, Figure 2 As shown, the head-mounted display device 100 is an AR glasses, which are worn on the head of the user 101, so that the user 101 can clearly know the relationship between the direction indicated above the navigation interface and the direction the user is facing through the direction indication information displayed by the AR glasses.

[0067] The following will be combined Figure 1 and Figure 2 The direction indication method provided by the embodiment of the present invention is described in detail in the scenario in FIG. Figure 1 and Figure 2 The scenario is only used to explain the direction indication method provided by the embodiment of the present invention, but does not constitute a limitation on the application scenario of the direction indication method provided by the embodiment of the present invention.

[0068] See also Figure 3 , Figure 3 It is a flow chart of a direction indication method provided by an embodiment of the present invention.

[0069] The direction indication method can be applied to a head-mounted display device to improve the accuracy of direction indication, avoid users with a weak sense of direction from being unable to discern the direction indicated by the navigation software, and improve the user experience.

[0070] like Figure 3 As shown, the direction indication method includes steps S101 to S103.

[0071] Step S101, obtaining a first longitude and latitude of a starting position and a second longitude and latitude of a destination position.

[0072] In this embodiment, the starting position and the destination position can be selected or input by the user in the map based on the actual situation, and the embodiment of the present invention does not specifically limit this. The first longitude and latitude of the starting position and the second longitude and latitude of the destination position can be determined by the built-in positioning device of the head-mounted display device, or can be determined by the mobile terminal 200 through its own positioning device and then sent to the head-mounted display device 100, and the embodiment of the present invention does not specifically limit this. Among them, the positioning device can be the Beidou satellite navigation system, the Global Positioning System (GPS), the Greiner navigation system or the Galileo navigation system, etc.

[0073] Step S102: determine the target azimuth according to the first longitude and latitude and the second longitude and latitude, and determine the current azimuth corresponding to the current orientation of the user through a nine-axis inertial measurement unit.

[0074] In this embodiment, the coordinate system in which the target azimuth is located is the same as the coordinate system in which the current azimuth corresponding to the user's current orientation is located. For example, the coordinate systems in which the target azimuth and the current azimuth corresponding to the user's current orientation are both based on the true north direction, with the clockwise direction as a positive value. The current azimuth corresponding to the user's current orientation is determined by the head-mounted display device through its own nine-axis inertial measurement unit. For example, the head-mounted display device is AR glasses. After the user wears the AR glasses, the orientation of the AR glasses is fixed. The azimuth determined by the AR glasses through its own nine-axis inertial measurement unit is the current azimuth corresponding to the user's current orientation, thereby avoiding changes in the user's current orientation due to the user's movement, which affects the accuracy of the direction indication.

[0075] In some embodiments, determining the target azimuth according to the first longitude and longitude and the second longitude and longitude may include: determining the longitude difference between the starting position and the destination position according to the first longitude and longitude and the second longitude and longitude; determining the target azimuth according to the first longitude and longitude, the second longitude and longitude and the longitude difference.

[0076] For example, let the first longitude and latitude of the starting position be (current_lon, current_lat), and the second longitude and latitude of the target position be (destination_lon, destination_lat), that is, the first longitude and latitude of the starting position are current_lon and current_lat, and the second longitude and latitude of the target position are destination_lon and destination_lat. Convert the first longitude and longitude to radians to obtain the longitude radian value α1=current_lon*π / 180 and the latitude radian value β1=current_lat*π / 180 of the starting position, and convert the second longitude and longitude to radians to obtain the longitude radian value α2=destination_lon*π / 180 and the latitude radian value β1=destination_lat*π / 180 of the target position. Then determine the longitude difference Δα=α1-α2 between the starting position and the destination position, and use the azimuth calculation formula atan2(sin(Δα)*cosβ2, cosβ1*sinβ2-sinβ1*cosβ2*cos(Δα)) to calculate the target azimuth based on the latitude radian value of the starting position, the latitude radian value of the destination position, and the longitude difference between the starting position and the destination position. Δα is the longitude difference between the starting position and the destination position, β1 is the latitude radian value of the starting position, and β2 is the latitude radian value of the destination position.

[0077] Step S103: Generate direction indication information according to the target azimuth and the current azimuth, and display the direction indication information.

[0078] In this embodiment, the direction indication information is used to indicate the direction and angle that the user wants to turn relative to the current position. For example, the direction indication information may be to turn 45° to the left, or to turn 25° to the right, etc. In this embodiment, the direction indication information is generated by the target azimuth and the current azimuth, and the direction indication information is displayed by the head-mounted display device, so that the user can clearly know the relationship between the direction indicated on the navigation interface and the direction the user is facing, thereby improving the accuracy of the direction indication and avoiding the situation where users with a weak sense of direction cannot distinguish the direction indicated by the navigation software.

[0079] In some embodiments, generating direction indication information according to the target azimuth and the current azimuth may include: determining direction deviation information according to the target azimuth and the current azimuth; and generating corresponding direction indication information according to the direction deviation information. Wherein, determining direction deviation information according to the target azimuth and the current azimuth may include: subtracting the current azimuth from the target azimuth to obtain the azimuth difference. By generating corresponding direction indication information through direction deviation information, the direction indication information can accurately feedback the offset between the target azimuth and the current azimuth, making it easier for users to adjust the direction by themselves, and avoiding users with weak sense of direction from being unable to distinguish the direction indicated by the navigation software.

[0080] In some embodiments, the direction deviation information may be an azimuth difference. According to the direction deviation information, generating corresponding direction indication information may include: when the azimuth difference is greater than zero, generating first direction indication information corresponding to the azimuth difference, the first direction indication information is used to instruct the user to rotate a first angle along a first direction relative to the current position, and the value of the first angle is equal to the azimuth difference; when the azimuth difference is less than zero, generating second direction indication information corresponding to the azimuth difference, the second direction indication information is used to instruct the user to rotate a second angle along a second direction relative to the current position, and the value of the second angle is equal to the absolute value of the azimuth difference; when the azimuth difference is equal to zero, generating third direction indication information corresponding to the azimuth difference, the third direction indication information is used to indicate that the angle to be rotated by the user relative to the current position is zero.

[0081] For example, if the azimuth difference is zero, it means that the user's current direction is facing the direction corresponding to the target azimuth. At this time, the direction indication information generated may be "the user's direction is consistent with the target direction", and the user can move according to the current direction. If the azimuth difference is -30°, it means that the direction corresponding to the target azimuth is located to the left of the user's current direction. At this time, the direction indication information generated may be "turn 30° left along the current direction". After the user turns 30° to the left along the current direction, the user's direction is consistent with the target direction. If the azimuth difference is 30°, it means that the direction corresponding to the target azimuth is located to the right of the user's current direction. At this time, the direction indication information generated may be "turn 30° right along the current direction". After the user turns 30° to the right along the current direction, the user's direction is consistent with the target direction.

[0082] In some embodiments, a navigation path is generated based on the first longitude and latitude and the second longitude and latitude, and the navigation path is displayed while the direction indication information is displayed. In this embodiment, by generating a navigation path and displaying the navigation path while the direction indication information is displayed by the head mounted display device, the user can accurately move along the navigation path according to the direction indication information, thereby improving the accuracy of navigation.

[0083] See also Figure 4 , Figure 4 This is a flow chart of another direction indication method provided by an embodiment of the present invention. The direction indication method is applied to a mobile terminal to improve the accuracy of direction indication, avoid users with a weak sense of direction from being unable to distinguish the direction indicated by the navigation software, and improve user experience.

[0084] like Figure 4 As shown, the direction indication method includes steps S201 to S203.

[0085] Step S201, obtaining a first longitude and latitude of a starting position and a second longitude and latitude of a destination position, and determining a target azimuth according to the first longitude and latitude and the second longitude and latitude.

[0086] In this embodiment, the starting position and the destination position can be selected or input by the user in the map based on actual conditions, and the embodiment of the present invention does not specifically limit this. The first longitude and latitude of the starting position and the second longitude and latitude of the destination position can be determined by a positioning device built into the mobile terminal. Among them, the positioning device can be a Beidou satellite navigation system, a global positioning system (GPS), a Grenades navigation system or a Galileo navigation system, etc.

[0087] In some embodiments, determining the target azimuth according to the first longitude and longitude and the second longitude and longitude may include: determining the longitude difference between the starting position and the destination position according to the first longitude and longitude and the second longitude and longitude; determining the target azimuth according to the first longitude and longitude, the second longitude and longitude and the longitude difference. It should be noted that the specific implementation method of determining the target azimuth according to the first longitude and longitude, the second longitude and longitude and the longitude difference can refer to the corresponding process in the aforementioned embodiment, which is not repeated here. Among them, the coordinate system in which the target azimuth is located is a coordinate system with due north as the reference and clockwise as positive values.

[0088] Step S202: Obtain a current azimuth angle corresponding to the user's current orientation sent by the head mounted display device.

[0089] In this embodiment, the coordinate system of the current azimuth corresponding to the current orientation is a coordinate system with the true north direction as the reference and the clockwise direction as the positive value. The head-mounted display device includes a nine-axis inertial measurement unit, and the current azimuth corresponding to the user's current orientation is determined by the head-mounted display device through its own nine-axis inertial measurement unit. For example, the head-mounted display device is AR glasses. After the user wears the AR glasses, the orientation of the AR glasses is fixed. The azimuth determined by the AR glasses through its own nine-axis inertial measurement unit is the current azimuth corresponding to the user's current orientation, so as to avoid the user's current orientation changing due to the user's movement and affecting the accuracy of the direction indication.

[0090] In some embodiments, obtaining a current azimuth corresponding to a user's current orientation sent by a head-mounted display device may include: a mobile terminal sends a query request for the user's current orientation to the head-mounted display device; when the head-mounted display device receives the query request, the head-mounted display device determines the current azimuth corresponding to the user's current orientation through its own nine-axis inertial measurement unit, and sends the current azimuth to the mobile terminal; the mobile terminal obtains the current azimuth corresponding to the user's current orientation returned by the head-mounted display device based on the query request.

[0091] Step S203: Generate direction indication information according to the target azimuth and the current azimuth, and send the direction indication information to the head mounted display device so that the head mounted display device displays the direction indication information.

[0092] In this embodiment, the direction indication information is used to indicate the direction and angle that the user wants to turn relative to the current position. For example, the direction indication information may be 45° to the left, or 25° to the right. The mobile terminal generates the direction indication information through the target azimuth and the current azimuth, and the head-mounted display device displays the direction indication information, so that the user can clearly know the relationship between the direction indicated on the navigation interface and the direction the user is facing, thereby improving the accuracy of the direction indication and preventing users with a weak sense of direction from being unable to distinguish the direction indicated by the navigation software.

[0093] In some embodiments, generating direction indication information according to the target azimuth and the current azimuth may include: determining direction deviation information according to the target azimuth and the current azimuth; and generating corresponding direction indication information according to the direction deviation information. Wherein, determining direction deviation information according to the target azimuth and the current azimuth may include: subtracting the current azimuth from the target azimuth to obtain the azimuth difference. By generating corresponding direction indication information through direction deviation information, the direction indication information can accurately feedback the offset between the target azimuth and the current azimuth, making it easier for users to adjust the direction by themselves, and avoiding users with weak sense of direction from being unable to distinguish the direction indicated by the navigation software.

[0094] In some embodiments, the direction deviation information may be an azimuth difference. According to the direction deviation information, generating corresponding direction indication information may include: when the azimuth difference is greater than zero, generating first direction indication information corresponding to the azimuth difference, the first direction indication information is used to instruct the user to rotate a first angle along a first direction relative to the current position, and the value of the first angle is equal to the azimuth difference; when the azimuth difference is less than zero, generating second direction indication information corresponding to the azimuth difference, the second direction indication information is used to instruct the user to rotate a second angle along a second direction relative to the current position, and the value of the second angle is equal to the absolute value of the azimuth difference; when the azimuth difference is equal to zero, generating third direction indication information corresponding to the azimuth difference, the third direction indication information is used to indicate that the angle to be rotated by the user relative to the current position is zero.

[0095] In some embodiments, a navigation path is generated based on the first longitude and latitude and the second longitude and latitude; the navigation path is sent to a head mounted display device so that the head mounted display device displays the navigation path while displaying the direction indication information. In this embodiment, the head mounted display device displays the navigation path while displaying the direction indication information, so that the user can accurately move along the navigation path according to the direction indication information, thereby improving the accuracy of navigation.

[0096] See also Figure 5 , Figure 5 This is a flow chart of another direction indication method provided by an embodiment of the present invention. The direction indication method is applied to a mobile terminal to improve the accuracy of direction indication, avoid users with a weak sense of direction from being unable to distinguish the direction indicated by the navigation software, and improve user experience.

[0097] like Figure 5 As shown, the direction indication method includes steps S301 to S303.

[0098] Step S301, obtaining the first longitude and latitude of the starting position and the second longitude and latitude of the destination position.

[0099] In this embodiment, the starting position and the destination position can be selected or input by the user in the map based on actual conditions, and the embodiment of the present invention does not specifically limit this. The first longitude and latitude of the starting position and the second longitude and latitude of the destination position can be determined by a positioning device built into the mobile terminal. Among them, the positioning device can be a Beidou satellite navigation system, a global positioning system (GPS), a Grenades navigation system or a Galileo navigation system, etc.

[0100] Step S302: determine the target azimuth according to the first longitude and latitude and the second longitude and latitude, and determine the current azimuth corresponding to the current orientation of the user through a nine-axis inertial measurement unit.

[0101] In this embodiment, the mobile terminal can determine the current azimuth corresponding to the user's current orientation through its own nine-axis inertial measurement unit without the need for external equipment, thereby improving the convenience of implementing direction indication.

[0102] In some embodiments, determining the target azimuth according to the first longitude and longitude and the second longitude and longitude may include: determining the longitude difference between the starting position and the destination position according to the first longitude and longitude and the second longitude and longitude; determining the target azimuth according to the first longitude and longitude, the second longitude and longitude and the longitude difference. It should be noted that the specific implementation method of determining the target azimuth according to the first longitude and longitude, the second longitude and longitude and the longitude difference can refer to the corresponding process in the aforementioned embodiment, which is not repeated here. Among them, the coordinate system in which the target azimuth is located is a coordinate system with due north as the reference and clockwise as positive values.

[0103] Step S303: Generate direction indication information according to the target azimuth and the current azimuth, and output the direction indication information.

[0104] In this embodiment, the direction indication information is used to indicate the direction and angle that the user wants to turn relative to the current position. For example, the direction indication information may be to turn 45° to the left, or to turn 25° to the right, etc. After generating the direction indication information, the mobile terminal may directly display and / or broadcast the direction indication information, so that the user can clearly know the relationship between the direction indicated above the navigation interface and the direction the user is facing, thereby improving the accuracy of the direction indication and avoiding the situation where users with a weak sense of direction cannot distinguish the direction indicated by the navigation software. It should be noted that the specific implementation method of generating the direction indication information according to the target azimuth and the current azimuth can refer to the corresponding process in the aforementioned embodiment, which will not be described in detail here.

[0105] In some embodiments, the mobile terminal is in communication with the head mounted display device, and outputting the direction indication information may include: sending the direction indication information to the head mounted display device, so that the head mounted display device displays the direction indication information. In this embodiment, the head mounted display device displays the direction indication information, so that the user can read the direction indication information more conveniently, thereby improving the user experience.

[0106] In some embodiments, generating direction indication information according to the target azimuth and the current azimuth may include: determining direction deviation information according to the target azimuth and the current azimuth; and generating corresponding direction indication information according to the direction deviation information. Wherein, determining direction deviation information according to the target azimuth and the current azimuth may include: subtracting the current azimuth from the target azimuth to obtain the azimuth difference. By generating corresponding direction indication information through direction deviation information, the direction indication information can accurately feedback the offset between the target azimuth and the current azimuth, making it easier for users to adjust the direction by themselves, and avoiding users with weak sense of direction from being unable to distinguish the direction indicated by the navigation software.

[0107] In some embodiments, the direction deviation information may be an azimuth difference. According to the direction deviation information, generating corresponding direction indication information may include: when the azimuth difference is greater than zero, generating first direction indication information corresponding to the azimuth difference, the first direction indication information is used to instruct the user to rotate a first angle along a first direction relative to the current position, and the value of the first angle is equal to the azimuth difference; when the azimuth difference is less than zero, generating second direction indication information corresponding to the azimuth difference, the second direction indication information is used to instruct the user to rotate a second angle along a second direction relative to the current position, and the value of the second angle is equal to the absolute value of the azimuth difference; when the azimuth difference is equal to zero, generating third direction indication information corresponding to the azimuth difference, the third direction indication information is used to indicate that the angle to be rotated by the user relative to the current position is zero.
