Detailed Description

The embodiment of the specification provides a navigation processing method, a navigation processing device, navigation processing equipment and a storage medium.

In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any inventive step based on the embodiments of the present disclosure, shall fall within the scope of protection of the present application.

The scheme aims to provide an auxiliary decision for a user in the outdoor navigation process by combining the weather condition and the terrain condition. The principle comprises the following steps: the navigation path is combined with weather prediction data of several hours in the future, weather conditions and shielding protection conditions accompanying the user in the path process are calculated and deduced, and accurate marks are made on a map. The details will be described below.

Fig. 1 is a flowchart illustrating a navigation processing method according to one or more embodiments of the present disclosure. The method can be applied to navigation software, particularly navigation application on mobile terminals such as smart phones and smart watches, and the effect of the method is mainly presented to users through electronic maps in the navigation application.

The process in fig. 1 may include the following steps:

s102: in response to a navigation request by a user, an alternative navigation path is generated for the electronic map.

In one or more embodiments of the present description, one or more selectable navigation paths are generated according to a current travel type and a specified departure location and a target location, and the navigation paths may be displayed to a user after being subjected to auxiliary marking according to weather information and terrain information.

S104: and obtaining adverse weather information corresponding to the navigation path, and determining a weather warning sub-path in the navigation path according to the adverse weather information.

Adverse weather information such as weather forecast information obtained from the weather bureau for a local future period of time, the adverse weather information corresponding to the navigation path includes: information of adverse weather that at least part of the road segment in the navigation path is encountering or may encounter next.

In some embodiments below, the navigation path generated is a walking path or a riding path, mainly for the type of travel that the user may be exposed to an outdoor environment, such as walking or riding. In such scenarios, the adverse weather information is indicative of at least one adverse weather of rain, snow, hail (with physical precipitation). For ease of use, adverse weather information may also include corresponding weather probabilities, weather intensities, and the like in more detail.

The weather warning sub-path is at least part of the path identified in the navigation path, and can dynamically change along with time change, weather change and actual travel plan change of the user.

S106: and acquiring terrain information of the navigation path, and determining a shielding protection sub-path in the navigation path according to the terrain information.

In one or more embodiments of the present disclosure, the topographic information of the navigation path includes information of buildings (e.g., pedestrian streets with rain-shed corridors, large malls, etc.) above the road surface (e.g., viaducts, underground tunnels, etc.) and on both sides thereof, such as height, width, shape, relative position to the road surface, etc. The topographic information is obtained from a real scene map, a three-dimensional map and the like corresponding to the electronic map.

The buildings can shield tangible falling objects caused by adverse weather, provide continuous or intermittent protection for a user, and can not only prevent the user from continuing to move on the navigation path under the adverse weather, but also determine the path as a shielding protection sub-path. In addition to buildings, for adverse weather without lightning, the topographical information of the navigation path may also include trees on both sides of the path, which may also provide shelter protection.

S108: and determining a routing auxiliary mark according to the weather warning sub-path and the shielding protection sub-path.

In one or more embodiments of the present disclosure, the routing assistance mark at least includes a weather warning sub-path, and may further include a more detailed description of the sub-path, such as a precipitation probability, a temperature, and the like, so as to guide a user to postpone a trip or select another trip method, or to go further after a countermeasure is taken.

In practical application, even if unfavorable weather exists, a user can stay on traveling, in this case, the shielding protection sub-path can help the user to reduce the difficulty of traveling, and different forms of routing auxiliary marks can be determined according to different degrees of help requirements of the user and according to the shielding protection sub-path. Such as simply marking how much of the occlusion protection is, marking the occlusion protection sub-path directly on the navigation path, eliminating the overlap of the occlusion protection sub-path with the weather alert sub-path, etc.

S110: and displaying a navigation path comprising the routing auxiliary mark in the electronic map.

After the display, the user can visually see which road sections are the weather warning sub-paths on the navigation path and can also visually see which road sections are the shielding protection sub-paths on the navigation path.

Based on the auxiliary information, the user can make a decision more reasonably. For example, other travel modes such as driving or public transportation are selected instead of walking and riding; for another example, avoiding time periods with severe weather; for another example, the adventure bump fortune continues to select an outdoor route, and a path with multiple shielding protection is selected to resist the risk depending on the information deduced by the system; and so on.

By the method of fig. 1, it is considered that in usage scenarios such as riding and walking, a user may pay special attention to weather conditions, such as adverse weather which may cause a physical falling object, like rain, snow, hail, may wet the clothes of the user, or even threaten the personal safety of the user, the adverse weather is considered in route selection, such as weather conditions which may be several hours in the future, and shielding protection terrain which can block the physical falling object caused by the adverse weather for the user is considered, so as to determine a weather warning sub-path and a shielding protection sub-path in an alternative navigation path, and accordingly mark the alternative navigation path in an electronic map to assist the user to use navigation services more reasonably, such a scheme is more closely combined with the usage scenarios, and is more considered by the user, which is helpful for improving the user experience.

Based on the process of fig. 1, some specific embodiments and embodiments of the process are also provided in the present specification, and the description is continued below.

In one or more embodiments of the present description, weather is time-varying, and the time a user travels may also vary, and these factors may also affect which road segments in the route the user will likely encounter adverse weather.

Based on this, determining the weather warning sub-path needs to consider these factors, specifically, for example, the following ways are adopted: estimating at least part of time length required for completing the navigation path, determining the time interval of the at least part of time length on a time axis, acquiring weather prediction information corresponding to each set moment in the time interval, determining adverse weather information corresponding to the navigation path according to the weather prediction information, and estimating a sub-path passing through the navigation path during the time sub-interval as a weather warning sub-path according to the time sub-interval of the adverse weather information in the time interval.

The time interval of at least part of the duration on the time axis depends on the travel time selected by the user, and the user can refer to the time of the adverse weather, and can advance or postpone the unreasonable travel time originally planned, so that the road section suffering from the adverse weather is shortened, and even the adverse weather is avoided. The default is to calculate the time interval from the current time (i.e. the default user goes out immediately), and allow the user to adjust the time of the trip, so that the position of the time interval on the time axis also changes.

In order to facilitate a user to visually and conveniently check the condition that the weather warning subpath dynamically changes along with the corresponding trip plan of the user, the scheme provides a weather time axis display area (which is provided with other improvements and provides an interface effect picture later) on the electronic map, wherein the weather time axis display area is used for identifying the set time and the weather prediction information corresponding to the set time, and the weather time axis display area also comprises a user operation control.

Assuming that the operation control is a selection box, the user can check the dynamic change condition of the weather warning sub-path on the navigation path by selecting different time intervals through the box. The method includes the steps that a user selects a time interval by sending a time interval framing instruction for a weather time axis display area, if the time interval framing instruction of the user is not received, a period of time (such as the next 2-3 hours or the estimated time consumption in the whole process) after the current time on a time axis is selected in a default mode, a framing part is determined to be the time interval of at least part of time duration on the time axis, and if the time interval framing instruction is received, the default framing part is adjusted towards the future time direction of the time axis according to the time interval framing instruction (which means that the user possibly wants to delay a trip and wants to see a weather warning sub-path at a later time), and the adjusted framing part is determined to be the time interval of at least part of time duration on the time axis.

In one or more embodiments of the present description, for a walking or riding user, the user may travel on both sides of the road surface in the presence of a vehicle lane, or may travel in the center of the road surface if no vehicle lane is present. If the road surface can be shielded as much as possible (for example, an underground passage, a viaduct overlapping with the road, and the like), more reliable protection can be provided; in addition to the shielding area, if the shielding can be performed continuously over a longer path (for example, buildings such as a corridor with a canopy in a pedestrian street, a shade lane, and the like), the user is greatly helped. Based on the method, the shading degree is measured by the shading area and/or the continuous shading path length, so that the shading protection sub-path is more accurately and reliably determined, and the reference value of the shading protection sub-path for a user is improved.

Specifically, information of a road surface and a building of the navigation path is acquired as topographic information, whether the building meets a shielding protection condition (for example, whether a shielding area ratio is greater than a set ratio, whether a continuous shielding path length is greater than a set length, and the like) is judged according to the shielding degree of the building to the road surface in the vertical direction, and a shielding protection sub-path is determined in the navigation path according to the building meeting the shielding protection condition.

In one or more embodiments of the present description, the physical falling objects, particularly rain and hail, directly affecting the user, caused by adverse weather, consider the shielding degree in the vertical direction, but the physical falling objects are affected by the wind direction, so that the falling trajectory is changed from vertical to inclined, in which case the originally shelterable area actually loses the shielding ability temporarily, and based on this, the present solution further considers the negative effect caused by the wind direction.

Specifically, whether the shielding degree of the building to the road surface in the vertical direction is not less than a set threshold value is judged, if yes, and the building is located on the weather warning sub-path, the shielding degree is corrected according to estimated local wind direction information when the user reaches the building, the height of the building (for example, the higher the viaduct is, the greater the actual shielding degree is affected by the wind direction), and the type of a tangible landing object corresponding to adverse weather information (different types of weights and shapes are different, and the degree of the effect of the wind direction is also different), and if the corrected shielding degree is not less than the set threshold value, the building is judged to meet the shielding protection condition. By correcting the shielding degree, the determined shielding protection sub-path has higher accuracy and better timeliness. In addition to the above factors, the width of the building (e.g., the width of the overpass), the material (e.g., whether the material is permeable to water, whether the material is resistant to impact, etc.), the state of the windward side (e.g., whether the material is open or blocked), and the like may be considered.

Taking the weight of the tangible falling object as an example, the weight condition of the tangible falling object can be determined according to the tangible falling object type corresponding to the adverse weather information, the preset vertical falling track of the tangible falling object is corrected to the deflection direction according to the weight condition of the tangible falling object and the estimated local wind direction information when the user arrives at the building, and the shielding degree is corrected to the direction of reducing according to the height of the building and the corrected falling track, so that the shielding degree which is more likely to be really realized when the user encounters the adverse weather is obtained.

In one or more embodiments of the present specification, in practical applications, there are two types of users who have a desire to travel (as far as they are to stay on time to travel) in adverse weather, one type is that they passively and actually need to travel, for example, go to work, meet customers, etc., and the other type is that they actively want to travel, typically, tourists, because they can stay in the local for a short time and need to fully utilize the time to obtain a travel harvest. The scheme further considers meeting the actual requirements of the other users in adverse weather and improving the experience of the other users.

For tourists, the travel path is a visiting process, the unfavorable weather brings inconvenience to the tourists, but the unfavorable weather also brings other environment scenes which are hard to see or not frequently seen by the tourists even the local people because the occurrence of the unfavorable weather is uncertain, and in the other environment scenes, scenes at the landscape level (which need to be explained is not a known scenery, so that surprise can be brought to the users, and the big data can be helpful to dig out new sceneries which are rare) are likely to exist, and the scene is a 'unfavorable weather-limited version' (the scenery which can be viewed in the unfavorable weather is not enough to be viewed by people in normal weather, but can be viewed by people in short), it is of practical value to tourists, and this situation can affect the decision of tourists on travel planning and navigation routes.

Based on the thought, when the shielding protection sub-path is determined, deeper analysis processing can be carried out, so that the weather-limited viewing guidance is further provided on the basis of providing shielding protection.

Specifically, for example, the topographic information may include a live-action image on the navigation path, a corresponding weather filter effect is determined according to the type of the unfavorable weather, the live-action image superimposed with the corresponding weather filter effect is predicted to determine a scene degree representation value of a location indicated by the live-action image in the unfavorable weather (the scene degree representation value reflects whether the corresponding location is enough to be a scene pleasing to a user in the unfavorable weather), a mask protection sub-path indicating a timely scene indication section is determined according to the scene degree representation value and a building meeting a mask protection condition, and the user may view an unusual scene in the timely scene indication section under the condition of obtaining mask protection, so as to guide the user (especially a visitor) to travel.

Further, for the same road segment on the navigation path, if the scene in adverse weather (e.g., rainy day) is better than the scene in normal weather (e.g., sunny day), it is particularly suitable to identify the road segment as the timely viewing indication road segment in the adverse weather. Based on the above, the scene prediction model obtained by training according to the first type sample and the second type sample can be obtained, the first type sample is a live-action image sample in adverse weather, the second type sample is a live-action image sample in normal weather relative to the adverse weather, the scene prediction model is utilized to predict the live-action image superimposed with the corresponding weather filter effect, and the goal is to identify a road section more suitable for passing under the adverse weather.

In one or more embodiments of the present disclosure, after determining the weather warning sub-path and the shelter protection sub-path, information reflected by the sub-paths is represented on an electronic map in the form of routing assistance marks. The navigation path can be displayed on the electronic map in a specific color (usually blue or green, and also yellow and red which reflect congestion conditions, etc.), and the specific relation between adverse weather and the path is further considered, so that the weather warning sub-path and the shielding protection sub-path can be intuitively represented by a color different from that of the navigation path to serve as a routing auxiliary mark. In a more concise display mode, in order to avoid the over-color appearance, the shielding protection subpath can be simply represented, for example, according to the shielding protection subpath, the degree of shielding protection on the navigation path is determined (for example, more shielding, less shielding, no shielding and the like), the degree of shielding protection and the weather warning subpath represented by different colors are determined as the auxiliary routing mark, in this case, a user can quickly know the specific condition of adverse weather and the rough condition of shielding protection, and the user can go out according to the mode and the route which are enough.

In practical application, a plurality of selectable navigation paths with the routing auxiliary marks are determined for a user, and a more matched navigation path is displayed for the user by identifying the current preference type of the user. For example, assuming that the user is a visitor from a different place according to the recent position change of the user, the navigation path with the highest degree of occlusion protection is determined as the navigation path with the highest recommendation level, and the navigation path with the highest recommendation level and the corresponding degree of occlusion protection are displayed on the electronic map by default.

The above description has been made on the idea and processing logic of the solution, and from the user perspective, the user directly feels the solution improvement from the interactive interface (navigation page), so the following provides an illustration of the comparison of the page effects to more intuitively aid understanding.

Fig. 2 is a diagram illustrating an effect of a conventional navigation page.

Included in fig. 2 are subfigures (a) and (b). In sub-diagram (a), the navigation route is from the current position of the user (i.e. my position) to the west stream a area of a certain place, and the selected travel mode is the riding, so the navigation application plans three selectable navigation paths which are more suitable for riding, and gives a recommendation according to the number of intersections, namely, the path which is displayed on the map and has the darkest color (e.g. dark blue in the color map), and the other two selectable paths are represented by a lighter color (e.g. light grey in the color map). Similarly, in sub-diagram (b), the main difference from sub-diagram (a) is that the selected travel mode is walking, and accordingly two alternative navigation paths are revealed that are more suitable for riding.

It can be seen that the navigation route in fig. 2 is planned from three dimensions of time, distance, and number of intersections according to the travel mode.

Fig. 3 is a diagram of an effect of a navigation page provided by one or more embodiments of the present disclosure.

In fig. 3, it can be seen that compared with the prior art, a new annotation is added to the navigation path, including: information reflecting the weather alert subpath (including alerts with precipitation probability of 40%, and the weather alert subpath itself represented by another color); the navigation path display system also comprises the weather event axis display area, and can display each moment on the time axis and the corresponding prediction information such as temperature, weather type, precipitation probability, wind direction and the like at intervals of every hour, the time interval from 'now' to '12 hours' is currently framed and selected in the area, and a user can adjust the time interval, so that the labels on the navigation path can be correspondingly matched and changed, and the user can conveniently preview the navigation path; the navigation path recommendation method further comprises a multi-mask label aiming at the recommendation scheme below the page, wherein the label reflects summary information of the mask protection sub-path and indicates that the currently recommended navigation path has more mask protection and can be used as a riding preferred path.

Fig. 4 is a diagram of another navigation page effect provided by one or more embodiments of the present disclosure.

Compared with fig. 3, in fig. 4, the shelter protection sub-path and the timely view indication road section included in the shelter protection sub-path are further labeled in the weather warning sub-path on the navigation path (that is, the whole shelter protection sub-path is assumed to be the timely view indication road section in the figure, the thickest road section is additionally labeled by a hexagon symbol), and the weather warning sub-path is additionally labeled by a lightning symbol. In practical applications, the navigation path, the weather warning sub-path, the shielding protection sub-path, and the timely viewing indication road section may be respectively represented by different colors, and more specifically, the degree of adverse weather, the degree of shielding protection, and the degree of beautiful scenery may be represented by color depth. In addition, under the weather time axis display area, information 'ink scenery in a rainy far mountain' reflecting the timely view indication road section is marked aiming at the recommendation scheme, which indicates that if the current departure is made, the weather is likely to be met on the weather warning sub-path, but the wonderful scenery as the same ink painting in a rainy far mountain which cannot be seen in a sunny day is likely to be seen on the timely view indication road section in the weather warning sub-path.

Based on the navigation page provided by the scheme, a user can select a navigation route more reasonably and arrange a trip plan, unfavorable weather can be predicted in advance, help brought by a shielding building under the unfavorable weather can be predicted, and special viewing experience which can be obtained by trip under the unfavorable weather can be known in advance, so that the user experience is improved, and resource allocation is optimized.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: the ARC625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory.
