S103. The navigation device performs reverse navigation on the user according to the sequence of the sub-paths included in the description information of the acquired path and the length information and direction information of the sub-path.

In the embodiment of the present invention, after acquiring the description information of a path through the description information of the at least one path, the navigation device selects the path sequence of the sub-path and the length information of the sub-path according to the description information of the acquired path. And direction information to reverse navigation to the user.

As an optional implementation manner, the specific implementation manner of the reverse navigation of the user by the navigation device according to the sequence of the sub-paths included in the description information of the acquired path and the length information and the direction information of the sub-path may include the following steps:

Step 81) The navigation device inverts the order of the sub-paths included in the description information of the acquired path, obtains the path sequence of at least one sub-path that constitutes the reverse navigation path, and includes each sub-item according to the description information of the acquired path.

Step 82) The navigation device follows the route order of the sub-paths of the reverse navigation path, and navigates the user according to the length information and direction information of each sub-path of the reverse navigation path.

In this embodiment, optionally, when performing step 82), the navigation device may output length information and direction information of each sub-path in the reverse navigation path on the display screen according to the path sequence of each sub-path of the reverse navigation path. Navigate the user. Alternatively, the navigation device may sequentially output the length information and the direction information of each sub-path of the reverse navigation path by the horn according to the path of each sub-path of the reverse navigation path to navigate the user.

For example, as shown in FIG. 1c, FIG. 1c is a schematic diagram of a route path and a reverse navigation path according to an embodiment of the present invention. The sub-paths included in the path are path 1 and path 2, and the length information of the path 1 is 50 meters. The direction information corresponding to the path 1 is northward, and the length information of the path 2 is 100 meters. To the east, the order of the sub-paths is first route 1 and then route 2. After the navigation device obtains the description information of the path, according to the principle that the path of the sub-path is reversed, the order of the path of the sub-path of the path is reversed (ie, path 2 is followed by path 1), and the reverse navigation path is obtained. The order of the sub-paths is reversed, and the direction information of path 1 and path 2 is reversed, and the length information of path 1 and path 2 is kept unchanged, and a reverse navigation path as shown in FIG. 1c is obtained. As shown in FIG. 1c, in the reverse navigation path shown in FIG. 1c, the path corresponding to path 2 of the reverse navigation path The direction information corresponding to the path 1 of the reverse navigation path is southward; the length information corresponding to the path 2 of the reverse navigation path is 100 meters, and the length information corresponding to the path 1 of the reverse navigation path is 50 meters. When navigating the user, the navigation device will guide the user to go west for 100 meters and then south for 50 meters according to the path route of path 2 and route 1 first.

Optionally, if the direction information corresponding to the reverse navigation path is absolute direction information, when the navigation device navigates the user by using the reverse navigation path, the navigation device may convert the absolute direction information into relative direction information, and use the relative direction information to navigate. For example, when the navigation device uses the reverse navigation path of FIG. 1c to navigate the user, if the direction that the user is currently facing is northward, the direction information corresponding to the path 2 of the reverse navigation path output by the navigation device is relative to the current face. The direction is to the left, and the direction information corresponding to the path 1 of the reverse navigation path output by the navigation device is leftward.

For example, as shown in FIG. 1d, FIG. 1d is a schematic diagram of another path and a reverse navigation path disclosed in the embodiment of the present invention. The sub-paths included in the path shown in FIG. 1d are path 1 and path 2, the length information of the path 1 is 50 meters, the direction information corresponding to the path 1 is forward, and the length information of the path 2 is 100 meters, and the path 2 is The corresponding direction information is rightward relative to path 1, and the order of the sub-paths is first path 1 and then path 2. After the navigation device obtains the description information of the path, according to the principle that the path of the sub-path is reversed, the order of the path of the sub-path of the path is reversed (ie, path 2 is followed by path 1), and the reverse navigation path is obtained. The order of the path of the sub-path, and reverse the direction information of the path 2 with respect to the path 1, obtaining the direction information of the path 1 with respect to the path 2 (to the left with respect to the path 2), and maintaining the length information of the path 1 and the path 2 Without change, a reverse navigation path as shown in Figure 1d is obtained. In the reverse navigation path shown in FIG. 1d, the direction information corresponding to the path 2 of the reverse navigation path is forward, the direction information corresponding to the path 1 of the reverse navigation path is leftward, and the length information corresponding to the path 2 of the reverse navigation path is At 100 meters, the length information corresponding to path 1 of the reverse navigation path is 50 meters. When the navigation device uses the reverse navigation path to navigate the user, the user will guide the user to go forward for 100 meters and then to the left for 50 meters according to the route route of the route 2 and the route 1 . When using the reverse navigation path to navigate the user, the user needs to adjust the starting direction.

Optionally, when performing step 82), the navigation device may indicate the initial running direction of the user according to the path sequence of the sub-path of the reverse navigation path and the direction information of the sub-path of the reverse navigation path; and, the navigation device may The sensor device configured by itself detects the running direction of the user and the distance the user runs in the running direction in real time, according to the running direction of the user detected in real time, the distance the user runs in the running direction, and the direction of the sub path of the reverse navigation path. Information and length information, Direct direction guidance to users in real time.

For example, as shown in FIG. 1e, FIG. 1e is a schematic diagram of a reverse navigation path according to an embodiment of the present invention. The sub-paths included in the reverse navigation path shown in FIG. 1e are path 1 and path 2, wherein the direction information corresponding to path 1 is northward, the length information corresponding to path 1 is 50, and the direction information corresponding to path 2 is eastward. The length information corresponding to path 2 is 100, and the path order of the sub-path is first path 1 and then path 2. After the navigation device starts to navigate, the navigation device will prompt the user to run north for 50 meters; the navigation device can detect whether the user's running direction is the northward direction, and if not, the navigation device can output a prompt message for prompting the running direction to be incorrect. If yes, the navigation device continues to detect the distance that the user runs northward; when the difference between the length of the path 1 and the distance traveled by the user to the north is less than or equal to a preset threshold, the navigation device guides the user to the running direction corresponding to the path 2, Realize direction guidance to users in real time. For example, when the navigation device runs 45 meters according to the northward distance of the user, if the preset threshold is 5, the navigation device may prompt the user to run 100 meters to the east and then run 100 meters to the east.

As an optional implementation manner, the description information of the path further includes environment identification information, and the navigation device may further perform the following steps:

Step 91) detecting, in the process of performing reverse navigation on the user, the identification information of the environment in which the user is currently located;

Step 92) determining whether the identification information of the current environment of the user matches the environmental identification information;

Step 93) If there is no match, the prompt information for prompting that the running path is incorrect is output.

In this embodiment, the description information of the path further includes one or more environment identification information, and the environment identification information may be text information or image information of the environment identifier, and the like, which is not limited in the embodiment of the present invention.

In this embodiment, optionally, the environment identification information may correspond to a relative position in the sub path of the path (the relative position may be, for example, at the 40th meter of the sub path). If the environment identification information is at the 40th meter of the subpath of the route path and the subpath of the route path is 50 meters, the environment identification information is at the 10th meter of the subpath when the user is reversely navigated. During the reverse navigation of the user by the navigation device, when the navigation device detects that the user runs at a distance of 10 meters, the navigation device detects the environment identification information. Optionally, the navigation device can detect the environment identifier by using the camera device. information. When the navigation device detects the environmental identification information, it determines whether the detected environmental identification information matches the recorded environmental identification information. If not, the prompt information indicating that the running path is incorrect is output.

In practical applications, the user's running direction or running distance detected by the navigation device may have errors, and the user may not operate in the correct path according to the navigation instruction. The environment identification information of the preset location in the path can be recorded by the implementation of the embodiment. When the user arrives at the preset location, the environment identifier information corresponding to the preset location may be detected in the current environment again. If not, the indication is The running path is incorrect. It can be seen that by implementing steps 91) to 93), the user can be reversely navigated more accurately.

As an optional implementation manner, the description information of the path further includes running angle information, and the navigation device may further perform the following steps:

Step 101) in the process of performing reverse navigation on the user, detecting the current running angle information of the user compared to the horizontal direction;

Step 102) determining whether the currently detected running angle information matches the running angle information included in the description information of the acquired route path;

Step 103) If not matched, output prompt information for prompting that the running path is incorrect.

In this embodiment, the description information of the path may include one or more operating angle information, which may include an angle value with respect to the horizontal direction, and direction information compared to the horizontal direction. For example, if the user is currently running in a direction obliquely upward by 30 degrees compared to the horizontal direction, the navigation device can detect that the current running angle information of the user compared to the horizontal direction by the angle sensor is: the angle value with the horizontal direction is 30. Degree, and the direction is upward in the horizontal direction.

In this embodiment, optionally, the description information of the path includes the running angle information corresponding to a relative position in the sub path of the path (the relative position may be, for example, at the 40th meter of the sub path). For example, if the running angle information 1 corresponds to the 40th meter of the sub path of the path path and the sub path of the path path is 50 meters, the navigation device detects that the user is in the process of reverse navigation to the user. When the running distance of the sub-path is 10 meters, the navigation device determines whether the currently detected running angle information matches the running angle information 1. If not, the prompt information for prompting that the running path is incorrect is output. For example, if the running angle information 1 is 30 degrees from the horizontal direction and the direction is upward in the horizontal direction, when the navigation device detects that the current running angle information of the user is 30 degrees from the horizontal direction, When the direction is down in the horizontal direction, the navigation device determines that the currently detected running angle information matches the running angle information 1. Otherwise, the navigation device determines that the currently detected running angle information does not match the running angle information 1.

By implementing steps 101) to 103), the user can be more accurately navigated backwards.

In the method described in FIG. 1 , after receiving the navigation instruction, the navigation device acquires description information of a route path from the description information of the at least one path of the record, and forms the route according to the description information of the acquired route path. The user's reverse navigation is performed on the path sequence and sub-path length information and direction information of the sub-path of the path. It can be seen that, by implementing the embodiment of the present invention, the navigation device can obtain the route sequence of the sub-path of the reverse navigation path and the length information and direction of the sub-path according to the path sequence of the sub-path of the path path and the length information and direction information of the sub-path. Information, and according to the path of each sub-path of the reverse navigation path, the length information and the direction information of each sub-path of the reverse navigation path are outputted by the display screen or the horn to reversely navigate the user; or the navigation device can navigate through The sensor of the device detects the running direction and running distance of the user in real time, and performs real-time reverse navigation on the user according to the path sequence of the sub-path of the reverse navigation path and the direction information of the sub-path of the reverse navigation path, so that the user does not need to pass The network is used for navigation, which reduces the environmental network deployment requirements during the navigation process.
