All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The navigation function may help a user determine a route to a target location and a forward direction, and thus is frequently used in daily life. In order to guide the user in real time, the related art generally acquires the position of the user in real time, and displays a heading and a planned route on a map so as to guide the user to proceed. However, in an area with dense buildings or in an indoor area, signals for positioning such as satellite signals may be attenuated, resulting in a decrease in positioning accuracy. Inaccurate positioning can cause deviation of a navigation planning line, and further misleading is generated for a user. Therefore, the related art has a problem of poor navigation accuracy and navigation effect.

And acquiring a corresponding live-action guidance image after the navigation route is determined, constructing a live-action guidance image set by using the corresponding live-action guidance image, and guiding the user in a mode of outputting the live-action guidance image set. Because the position of the user does not need to be acquired in real time in the navigation process, and navigation is not needed to be carried out according to the real-time position, the problem of reduction of navigation accuracy caused by inaccurate positioning is avoided, and the navigation effect is improved.
In particular, in one possible implementation, please refer to fig. 1. Fig. 1 is a flowchart of an image navigation method according to an embodiment of the present invention, where the method includes:
s101: and acquiring the navigation path, and determining a plurality of guide nodes in the navigation path.
It should be noted that, some or all of the steps of the image navigation method provided by the present invention may be executed by a designated device or terminal, and the device or terminal may be referred to as the present device, and a specific form of the present device is not limited in this embodiment, and may be, for example, a mobile phone, a tablet computer, or a computer.
The navigation path is a path from a starting point to an end point, which the user wants to pass through, and the specific content of the navigation path is related to the end point of the path according to the starting point of the path. The navigation path acquisition mode is not limited in this embodiment, and may be generated according to path information input by a user, for example; or analyzing the path message when receiving the path message to directly obtain the navigation path, wherein the path message can be sent by other terminals or equipment.
And a guide node exists on the navigation path, and the guide node is a position node and is used for representing the position of acquiring the live-action guide image. The specific content of the guidance node is not limited in this embodiment, and may be, for example, a starting point of the navigation route, an end point of the navigation route, a turning point of the navigation route, or an intersection of the navigation route and another route. The guide node corresponds to the navigation path, which is necessarily on the navigation path. The number of the guide nodes is plural, and the specific number is not limited in this embodiment and can be set according to actual situations.
S102: and acquiring the live-action guide image corresponding to each guide node according to the navigation path.
After the guide node is determined, a live-action guide image corresponding to the guide node is obtained so as to guide the user. The real-scene guide image is a real-scene image with guide information, the guide information may include a forward direction, a forward path, or a forward manner of the user, and the form of the guide information may be a text description, a static or dynamic graphic indication, and the like, which is not limited in this embodiment. It should be noted that, since the navigation path has directionality, that is, from the path starting point to the path ending point, when the live-action guidance image corresponding to the guidance node is acquired, the navigation path is acquired according to the real-action guidance image, so as to obtain the real-action guidance image whose direction is consistent with the direction of the navigation path.
The live-action guide image is based on a live-action image, and the live-action image is an image for recording a real environment. In this embodiment, since the real-time position of the user is not obtained, in order to make the user know the current position of the user and determine the heading direction, a real-scene guidance image based on the real-scene image is required. Furthermore, the real-scene guide image is a real-scene image, and for some users with poor direction sense or users with poor abstract graphic understanding ability, the real-scene guide image can more conveniently position the position of the real-scene guide image, so that the user can conveniently correspond the current environment to the real-scene guide image, and the navigation effect is further improved.
S103: and forming a live-action guide image set by using the live-action guide images, and outputting the live-action guide image set.
And after obtaining a plurality of live-action guide images, forming a live-action guide image set by using the live-action guide images, and navigating the user by outputting the live-action guide image set. Specifically, the embodiment does not limit the specific way of outputting the live-action guide image set, and for example, the live-action guide image set may be output through a preset port and output to a display screen for display; or the data can be output to a position corresponding to a preset path for storage according to the preset path; or may be sent to other devices or terminals, i.e., the set of live-action guide images is output to the other devices or terminals.
By applying the image navigation method provided by the embodiment of the invention, the navigation path is determined firstly, and the live-action guidance image is obtained according to the guidance node in the navigation path, and the live-action guidance image contains guidance information and is used for generating the live-action guidance image set. And after the live-action guide image is used for generating a live-action guide image set, the live-action guide image set is output, so that a user can determine the advancing direction according to the live-action guide image set, and the navigation function is realized. The method does not need to acquire a real-time position during navigation and determine a planned route according to the real-time position, so that the interference caused by the fact that the real-time position cannot be accurately acquired can be avoided, the navigation accuracy is improved, the navigation effect is improved, the navigation application range is expanded, and the problems of poor navigation accuracy and poor navigation effect in the related technology are solved. Meanwhile, the real-scene guide image set is adopted to replace a planar abstract graph and a planning line, so that the environment where the user is located can correspond to the real-scene guide image, and the navigation effect is further improved.
Based on the above embodiment, in a possible implementation manner, the live-action image may be marked according to the guidance information of the navigation path, so as to obtain the live-action guidance image. Referring to fig. 2, fig. 2 is a flowchart of a live-action guidance image method according to an embodiment of the present invention, including:
s201: and acquiring a panoramic image corresponding to the guide node.
The panoramic image is a panoramic image in which the surrounding environment is represented as much as possible by a wide-angle representation means. In the present embodiment, the live-action guidance image is generated using the panoramic image as the live-action image. The panoramic image can allow a user to observe a 360-degree real scene environment around the guide node, so that a better navigation effect is achieved. After the guidance nodes are determined, panoramic images corresponding to the guidance nodes need to be acquired, the panoramic images can be stored locally or in a cloud, for example, the panoramic images can be stored in a server, corresponding relations can be established between each guidance node and the corresponding panoramic image, and the panoramic images corresponding to the guidance nodes are acquired according to the corresponding relations.
S202: and extracting guide information corresponding to the navigation path.
After the panoramic image is acquired, the guidance information corresponding to the navigation path needs to be extracted, and specifically, the guidance information may be extracted from the navigation information corresponding to the navigation path. The guide information includes direction information and the like, and a live-action guide image matched with the navigation path can be obtained according to the guide information.
S203: and marking the panoramic image by using the guide information to obtain a live-action guide image.
And after the panoramic image is obtained, determining the panoramic image as a live-action image, and marking the panoramic image by using the guide information to obtain the live-action guide image. The specific method of marking is not limited in this embodiment, and for example, the real-image may be marked by using an arrow, a character, or an animation.
In one possible embodiment, to reduce the file size of the live-action guide image, the panoramic image may be sliced. Specifically, since the panoramic image records all real scenes around the guidance node, that is, 360-degree real scenes around the guidance node, the panoramic image can be segmented according to the guidance information to obtain a real image matched with the navigation path, so as to reduce the file size of the finally generated real-scene guidance image. For example, when the guidance information indicates that the node a advances in the south direction, the panoramic image corresponding to the node a may be segmented, and the specific segmentation method is not limited in this embodiment and may be set according to actual needs. For example, the southward part of the panoramic map may be segmented, and the segmented image may be determined as a live-action image; or the direction of the user reaching the a guide node and the south direction may be combined to segment the panoramic image, for example, if the user reaches the a guide node from the east direction, the image in the southeast direction of the a guide node may be segmented, and the segmented image is determined to be the live image.
In another possible implementation, the pre-marked image may be filtered with the guide information in order to obtain the live-action guide image more quickly. Referring to fig. 3, fig. 3 is a flowchart of another real-scene guidance image method according to an embodiment of the present invention, including:
s301: and extracting guide information corresponding to the navigation path.

S302: and screening the pre-marked images in the database according to the guide information to obtain the live-action guide image.
The database is preset in the embodiment, and can be a local database or a cloud database. The database stores pre-marked images, and each guide node corresponds to a plurality of pre-marked images. And after the guide information is obtained, screening the pre-marked image of the guide node by using the guide information, and determining the screened pre-marked image as the live-action guide image. Specifically, when only one pre-marked image passes the screening, the pre-marked image is directly determined as the live-action guide image; when there are a plurality of screened images, the live-action guidance image may be selected according to a preset selection rule, and the specific content of the preset selection rule is not limited in this embodiment, and may be, for example, a random selection rule or a polling selection rule.
In another possible implementation, in order to acquire the real-scene guide image more quickly and reduce the computing power requirement of the device, a server with stronger computing power may be used to acquire the real-scene guide image. Referring to fig. 4, fig. 4 is a flowchart of another real-scene guidance image method according to an embodiment of the present invention, including:
s401: and extracting guide information corresponding to the navigation path.
In this embodiment, in order to acquire the live-action guidance image matching the navigation path, it is also necessary to extract guidance information corresponding to the navigation path.
S402: and sending the guide information and the node information corresponding to the guide node to a server.
And after the guide information is acquired, the guide information and the node information corresponding to the guide node are sent to the server side together, so that the server side determines the live-action guide image according to the guide information and the node information. The embodiment does not limit the specific way of determining the live-action guide image by the server, and for example, the way described in fig. 2 or fig. 3 may be adopted. Because the server side has stronger computing power, the live-action guide image can be determined more quickly, and meanwhile, the computing power requirement on the equipment is reduced.
S403: and receiving the live-action guide image sent by the server.
After the live-action guide image is determined, the server sends the live-action guide image, and the equipment or the terminal can receive the live-action guide image sent by the server and perform subsequent operation by using the live-action guide image.
Based on the above embodiment, in one possible implementation, different guidance levels may be set, and the strength of the navigation guidance is determined according to the guidance levels.
