Detailed Description
Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
When a user uses the map AR navigation product to go to a certain place, there is a demand of switching the arrival mode during the journey, for example, after walking for a period of time, the user wants to temporarily take public transportation to reach the destination. The current solutions for such a demand are: the AR navigation product is manually exited, information of public transportation schemes is queried again based on the current position and the destination, and whether public transportation is to be taken to the destination is determined according to the scheme information. The disadvantage of this solution is that it requires manual switching and querying of various information, and the cost of interaction and time is high. For this reason, the present disclosure proposes a route navigation method to solve the above-described problems.
Fig. 1 shows a flow 100 according to one embodiment of a line navigation method of the present disclosure, comprising the steps of:
step 101, acquiring a current position of a terminal and an image to be subjected to augmented reality.
In this embodiment, the terminal may be a mobile terminal held by an object, where an image capturing device is provided on the mobile terminal, and the image capturing device may capture, in real time, a scene around the terminal or the object, and when the object has an augmented reality navigation requirement, an application supporting augmented reality display on the terminal is opened, and an image superimposed with an augmented reality indication identifier may be viewed in real time on an interface corresponding to the application, where the image to be augmented reality is an image captured, in real time, by the image capturing device after the object opens the application supporting augmented reality on the terminal to perform navigation.
In this embodiment, the execution body on which the line navigation method is executed may further implement the functions of the application, and may further provide a virtual reality navigation function for the object by superimposing an augmented reality indication identifier corresponding to the preselected route or the alternative route of the user in the image to be augmented reality, based on the preselected route of the object, so that the object experiences the display effect of the 3D virtual reality in the navigation process (as shown in fig. 2).
In this embodiment, the pre-selected route is a pre-selected preset type of route between the current location and the destination, and it should be noted that the preset type is a navigation type set by the object for the pre-selected route in the above application, and the navigation type may be a walking type, a riding type, a self-driving type, a driving type, or the like.
Step 102, determining a transfer area and a transfer type corresponding to the transfer area based on the image and the current position.
In this embodiment, the exchangeable area is an area for jumping from a preselected route to another type of exchangeable route, for example, the preselected route is a walking navigation route, the exchangeable route is a bus route, and the exchangeable area is a bus stop, a station, or the like. In this embodiment, the changeable route is a route different from the pre-selected route, and the transfer type of the changeable route may be the same as or different from the pre-selected route, but the transfer type of the changeable route and the pre-selected route both belong to the navigation type in the same navigation system, i.e. the transfer type of the changeable route and the pre-selected route belong to the same navigation type range. The navigation type range to which the navigation device belongs may be set based on the navigation requirement, for example, the range to which the navigation device belongs is: walking, public transportation, subway, self-driving, etc.
In this embodiment, the actual area where the object and the terminal of the object are located may be determined by the image to be augmented, for example, the regional characteristics (for example, the building, the clothing of the person, etc.) related to the region in the image to be augmented are identified, and the transformable area is determined by the regional characteristics. Further, the object can be positioned on the map through the current position; the attribute of each position point on the preselected route in the map is completely consistent with the attribute of the identified regional characteristics, the correct transfer area of the object is determined, and the transfer type corresponding to the transfer area can be determined further by the characteristics of the optional area. For example, if the selectable area is a subway station, the transfer type corresponding to the selectable area may be walking, public transportation, subway, etc.
Optionally, the determining the transfer area and the transfer type corresponding to the transfer area based on the image and the current position includes: dividing a circular area with the current position as a center and a preset distance (the preset distance can be determined by the walking path of an object, for example, 20 meters) as a radius, and taking the circular area as a changeable area; based on the image to be augmented reality, identifying the traffic identification and the road type in the image, and determining the transfer type corresponding to the transfer area through the road type and the traffic identification.
Optionally, the determining the transfer area and the transfer type corresponding to the transfer area based on the image and the current position includes: dividing a square area with the current position as a diagonal center and a preset distance (the preset distance can be determined by the walking path of the object, for example, 20 meters) as the length of the diagonal, and taking the square area as a convertible area; based on the image to be augmented reality, identifying the traffic identification and the road type in the image, and determining the transfer type corresponding to the transfer area through the road type and the traffic identification.
Step 103, based on the transfer type, it is detected whether there is a replaceable route between the exchangeable area and the destination with respect to the preselected route.
Wherein the preselected route is a preselected, preset type of route between the current location and the destination.
In this embodiment, the detecting whether there is a replaceable route between the exchangeable area and the destination with respect to the preselected route based on the transfer type includes: planning all pre-transfer routes from any point to a destination in a transfer area; in response to all of the pre-transfer routes having a pre-transfer route belonging to the transfer type, the pre-transfer route belonging to the transfer type is treated as a replaceable route, i.e., a replaceable route is detected.
In this embodiment, the pre-transfer route is a pre-transfer route on which the execution subject on which the line navigation method operates is based on a pre-selected transfer route between each position point of the transfer area to the destination, and the type of the pre-selected transfer route may be one of all types corresponding to the middle navigation type of the navigation system, i.e., the type of the pre-transfer route is the navigation type.
In this embodiment, the transfer type of the replaceable route may be the same as the preset type of the preselected route, or may be different from the preset type of the preselected route.
In response to detecting the replaceable route, the replaceable route and the preselected route are indicated on the image by the augmented reality indication mark 104.
In this embodiment, the replaceable route and the preselected route may be marked by using marking information, and the marking information for marking the replaceable route may be displayed on the terminal in an AR information format, and information such as the estimated arrival time, a specific trip scheme, and the like may be presented around the replaceable route by using the marking information.
When the labeling information and the replaceable route are rendered and displayed on the terminal to be augmented reality images, whether the object adopts the preselected route or the replaceable route can be judged according to the real-time traveling position of the object, and after the object travels for a certain distance, the AR presentation content of the unapplied replaceable route or the AR presentation content of the preselected route is subjected to blanking processing, so that the intelligent recommendation of the travel scheme and the scheme switching of the platform are realized under the condition that the AR navigation state is not exited.
In this embodiment, it may be indicated that different types of augmented reality indication identifiers are required to be superimposed on an image to be augmented reality, as shown in fig. 2, the augmented reality indication identifier a is used to indicate a walking navigation mode, and the labeling information of the preselected route indicated by the augmented reality indication identifier a is "25 meters in straight line", that is, the object in the handheld terminal in the current walking navigation state needs to travel 25 meters in straight line.
In this embodiment, when the transfer type of the replaceable route is different from the preset type of the preselected route and the augmented reality indication marks are required to be superimposed on the image to be augmented reality, the preselected route and the replaceable route may be indicated by using the augmented reality indication marks of different styles, as shown in fig. 3, specifically, the preselected route is a walking navigation route in a subway station, the replaceable route is a subway navigation route in the subway station, the first mark b is used to indicate the preselected route, the second mark c is used to indicate the replaceable route, and in fig. 3, the first mark b and the second mark c are dynamically displayed in real time as the object operates in the actual environment.
Alternatively, in one example of the present application, when the preselected route is a walking navigation route and there are multiple exchangeable routes, the same type of augmented reality indication marks may be used to indicate different exchangeable routes, respectively, and detailed information of the various exchangeable routes may be interpreted by labeling information of different contents, as shown in fig. 4, the augmented reality indication mark d is used to indicate the exchangeable route of which the navigation type is taxi, and in fig. 4, the labeling information is: taxis need to wait 30 minutes. As shown in fig. 5, the augmented reality indication identifier e is used for indicating that the navigation type is a replaceable route of a bus, and in fig. 5, the labeling information is: suggesting to take 15 roads, saving 15 minutes for you.
Optionally, the line navigation method may further include detecting whether the current position is located outside the transfer area; if the current position is detected to be located outside the exchangeable area, the indication of the exchangeable route in the image through the augmented reality indication mark is stopped.
Optionally, the line navigation method may further include: receiving a determination instruction to select a replaceable route, and stopping indicating the preselected route in the image by the augmented reality instruction identification based on the instruction.
In this alternative implementation, the instruction for determining the replaceable route may be an instruction issued by the object of the handheld terminal to determine to select the replaceable route, where the intention of the object is specified by the instruction: and selecting an exchangeable route for navigation.
In this embodiment, after obtaining the replaceable route, the execution subject renders the replaceable route in the image to be augmented reality of the terminal at the same time, and when the replaceable route is plural, the execution subject may also separately prompt each replaceable route in different manners.
The line navigation method provided by the embodiment of the disclosure includes the steps of firstly, acquiring a current position of a terminal and an image to be subjected to augmented reality; secondly, determining a transfer area and a transfer type corresponding to the transfer area based on the image and the current position; again, based on the transfer type, detecting whether there is a replaceable route between the transfer area and the destination relative to a preselected route, the preselected route being a pre-selected pre-set type of route between the current location and the destination; finally, in response to detecting the replaceable route, the replaceable route and the preselected route are indicated on the image by the augmented reality indication mark. Therefore, when a user runs on the current preselected route, the replaceable route is determined based on the acquired image to be enhanced and displayed, and the indication mark of the replaceable route is added on the image, so that intelligent recommendation of the travel scheme under the condition that the user does not exit the current augmented reality navigation state is realized, and user experience is improved.
In some optional implementations of the present embodiment, detecting whether there is a replaceable route between the availability of the transfer area and the destination with respect to the preselected route based on the transfer type includes: determining a pre-transfer route belonging to a transfer type from any point in the transfer area to the destination; screening out pre-transfer routes which are coincident with the near ends of the opposite transfer areas of the pre-selected routes in all the pre-transfer routes; based on the screened pre-transfer route, a replaceable route is determined that differs from the pre-selected route from any point in the convertible area to the destination.
In this alternative implementation, the screened pre-transfer route coincides with the pre-selected route, the coinciding zone is located in the exchangeable area, and the coinciding zone is located at the nearest proximal end of the pre-selected route to the exchangeable area. By screening the pre-transfer routes, pre-transfer routes that do not coincide with the preselected route, as well as pre-transfer routes that deviate from the preselected route direction, may be filtered out.
In this optional implementation manner, the determining, based on the screened pre-transfer route, a replaceable route that is different from the pre-selected route from any point in the transfer area to the destination may include: and comparing the screened pre-transfer route with the preselected route, and taking the screened pre-transfer route as a replaceable route if the screened pre-transfer route is different from the preselected route.
In the alternative implementation mode, a plurality of alternative navigation modes are provided for the navigation of the user by determining the alternative route, so that the navigation experience of the user is improved.
In the alternative implementation manner, the pre-transfer routes which are not overlapped with the pre-selected route can be removed by screening out the pre-transfer routes which are overlapped with the near end of the relative exchangeable area of the pre-selected route in all the pre-transfer routes, so that the pre-transfer routes in the opposite direction to the pre-selected route are removed, reliable basis is provided for providing the preferable exchangeable route for the object, and the accuracy of route navigation is ensured.
In this embodiment, the replaceable route may be determined based on the time consumption of the screened pre-transfer route, and in some optional implementations of this embodiment, the determining, based on the screened pre-transfer route, the replaceable route that is different from the pre-selected route from any point in the available transfer area to the destination includes: calculating the time consumption of the pre-transfer route and the pre-selected route selected by each screen; ascending sorting is carried out on time consumption of all the screened pre-transfer routes and the pre-selected routes; based on the ascending sort results, alternate routes of all screened pre-transfer routes that are different from the pre-selected route are determined.
In this optional implementation manner, determining, based on the ascending sort result, a replaceable route that is different from the preselected route among all the screened pre-transfer routes includes: and selecting a time-consuming pre-set (for example, the first 3 bits) route in the ascending sort result, removing a pre-selected route in the pre-set bit route, and taking the rest pre-transfer route as a replaceable route.
Optionally, determining the alternate route of all the screened pre-transfer routes that is different from the pre-selected route based on the ascending sort result comprises: judging whether the route with the shortest time consumption of the ascending sort result is a preselected route or not; in response to the shortest time consuming route being not the preselected route, the shortest time consuming pre-transfer route is treated as a replaceable route.
In the alternative implementation mode, the time consuming of each screened pre-transfer route and the time consuming of the preselected route are sequenced in an ascending order by calculating the time consuming of all the screened pre-transfer routes and the preselected route, and the route with the shortest time consuming can be determined, so that a reliable basis is provided for determining the replaceable route which is different from the preselected route in all the screened pre-transfer routes, and the reliability of the selection of the replaceable route is ensured.
Optionally, the determining, based on the screened pre-transfer route, a replaceable route that is different from the pre-selected route from any point in the replaceable area to the destination includes: calculating the time consumption of the pre-transfer route and the pre-selected route selected by each screen; comparing the time consumption of each screened pre-transfer route with the time consumption of the pre-selected route; the pre-transfer route that consumes less time than the pre-selected route is taken as a replaceable route that is distinct from the pre-selected route.
In this embodiment, the exchangeable route different from the preselected route may also be determined based on the length of the screened pre-transfer route and the transfer type corresponding to each pre-transfer route. The determining a replaceable route, which is different from a preselected route from any point in the replaceable area to the destination, based on the screened pre-transfer route includes: respectively calculating equivalent average lengths of each screened pre-transfer route and each pre-selected route, wherein the equivalent average lengths of each screened pre-transfer route and each pre-selected route correspond to the respective transfer type; ascending order is carried out on all equivalent lengths; and determining the replaceable routes which are different from the preselected route in all the screened pre-transfer routes based on the sequencing results of all the equivalent average lengths.
In this alternative implementation manner, in order to facilitate unified calculation of the pre-transfer route and the pre-selected route, different transfer type coefficients are set for the pre-transfer route of different transfer types, for example, the transfer type is walking, and the transfer type coefficient is 1.0; the transfer type is public transportation, and the transfer coefficient is 1.5; the transfer type is self-driving, and the transfer type coefficient is 2. After each pre-transfer route is obtained, calculating the route length of each screened pre-transfer route, dividing the route length of each screened pre-transfer route with the transfer type coefficient corresponding to the screened pre-transfer route, and obtaining the equivalent length corresponding to the screened pre-transfer route.
Similarly, if the preselected route is a determined route, the route length and the preset type of the preselected route are determined, the preset type of the preselected route is a unified type with the transfer type, that is, the preset type also has a transfer type coefficient, and the equivalent average length corresponding to the preselected route is obtained by dividing the route length of the preselected route and the transfer type coefficient corresponding to the preselected route.
In the alternative implementation mode, the equivalent lengths of the screened pre-transfer routes and the preselected routes are compared, so that a reliable basis is provided for determining the replaceable routes different from the preselected routes in all the screened pre-transfer routes, and the reliability of the selection of the replaceable routes is ensured.

In this embodiment, the traffic sign includes an indication sign, a road indication sign, an auxiliary sign, an indication mark line, and the like, and the sizes and rules of various traffic signs all have fixed requirements, and the type of transfer path which can be transferred relative to the current position of the object can be determined by the traffic sign in the image. Specifically, the transfer path may be of walking, subway, bus, self-driving, or the like.
In this embodiment, the image with the traffic sign feature may be identified in real time in the navigation image by the image identification technology, so as to determine whether the navigation image has the traffic sign.

step 601, acquiring a current position of a terminal and an image to be augmented reality.
Step 602, determining a transfer area and a transfer type corresponding to the transfer area based on the image and the current position.
Step 603, based on the transfer type, detects whether there is a replaceable route between the transfer area and the destination with respect to the preselected route.
Wherein the preselected route is a preselected, preset type of route between the current location and the destination.
In response to detecting the replaceable route, the replaceable route and the preselected route are indicated on the image by the augmented reality indication mark, step 604.
