FIG. 1 is a schematic illustration of a vehicle navigation processing scenario, as one example, that illustratively depicts screening of navigation routes that may be performed using interactions of an on-board system on a vehicle for navigation processing with a background server, in accordance with an embodiment of the present disclosure. As shown in fig. 1, in the vehicle navigation processing scene, a plurality of vehicles are included, wherein the vehicle 101 starts an automatic driving model, 2 navigation routes are displayed on a navigation interface 102 of the vehicle-mounted system, namely a navigation route S1 and a navigation route S2, and the navigation route S1 and the navigation route S2 adopt the same starting point a and destination B. Specifically, after receiving the navigation request sent by the vehicle, the background server may generate a plurality of candidate navigation routes shown as a navigation route S1 and a navigation route S2 for the vehicle according to the starting point information and the destination information in the navigation request, if a traffic limit height object (such as a culvert, a tunnel, a lifting rod, etc.) exists on a certain candidate navigation route, the background server obtains a weight for representing the traffic limit height condition according to the limit height condition of the traffic limit height object, so as to screen out a target navigation route from the plurality of candidate navigation routes, and may feed back an item of the screened navigation route to the navigation interface 102 of the vehicle-mounted system to display (not shown in the figure), or may also be selected by the user to feed back a plurality of candidate navigation routes (such as the navigation route S1 and the navigation route S2) to the navigation interface 102 of the vehicle-mounted system to display, and increase the limit height identification information 103 on the navigation route S1 of the traffic limit height object, and correspondingly, and may also display the limit height information of the traffic limit height object, the limit height information and the like.

According to an embodiment of the present disclosure, a navigation route screening method is provided, and fig. 2 is a schematic flow chart of a navigation route screening method according to an embodiment of the present disclosure, where the method may be applied to a navigation route screening apparatus, for example, where the apparatus may be deployed in a terminal or server or other processing device in a stand-alone, multi-machine or clustered system for execution, and may implement navigation route screening and so on. The terminal may be a User Equipment (UE), a mobile device, a Personal Digital Assistant (PDA), a handheld device, a computing device, an in-vehicle device, a wearable device, etc. In some possible implementations, the method may also be implemented by way of a processor invoking computer readable instructions stored in a memory. As shown in fig. 2, the method is applied to any node or electronic device (mobile phone or desktop, etc.) in the cluster system shown in fig. 1, and includes:
S201, acquiring a navigation request.
S202, obtaining a plurality of candidate navigation routes according to the starting point information and the destination information in the navigation request.
S203, screening target navigation routes from the candidate navigation routes according to the weight for representing the traffic limit height condition.
In an example of S201-S203, the background server obtains a navigation request sent by the vehicle, and may obtain a plurality of candidate navigation routes according to the start point information and the destination information in the navigation request. In view of the fact that there may be a height limit condition of the height limit object in the plurality of candidate navigation routes, in order to improve the traffic efficiency, the plurality of candidate navigation routes need to be screened (i.e. the target navigation route is screened out of the plurality of candidate navigation routes according to the weight for representing the traffic limit condition), so as to determine a final target navigation route, and the background server can feed back the target navigation route to the vehicle.
By adopting the embodiment of the disclosure, the background server can acquire the navigation request sent by the vehicle so as to obtain a plurality of candidate navigation routes according to the starting point information and the destination information in the navigation request, and can screen out the target navigation route from the plurality of candidate navigation routes according to the weight for representing the passing limit height condition, thereby improving the passing efficiency.

And recording first height limiting value information corresponding to the first passing height limiting object and second height limiting value information corresponding to the second passing height limiting object in the height limiting model library. By adopting the embodiment, the first traffic height limiting object (such as a fixed traffic height limiting object) and the second traffic height limiting object (such as an adjustable traffic height limiting object) can be classified, first height limiting value information (such as an actual height limiting value of the fixed traffic height limiting object) corresponding to the first traffic height limiting object and second height limiting value information (such as a height limiting action range of the adjustable traffic height limiting object) corresponding to the second traffic height limiting object are recorded, and therefore navigation route screening requirements of different users can be matched according to different classifications of the height limiting objects, and the traffic efficiency is improved.
In some examples, the fixed class of traffic height limiting objects may include bridge bottoms, tunnel culverts, fixed height limiting bars, pedestrian overpasses, portals, archways, billboards, camera/signal light crossbars, and the like, and the adjustable class of traffic height limiting objects may include height adjustable lifting height limiting bars, height adjustable drop bar height limiting bars, height adjustable side-hung height limiting bars, and the like.
In one embodiment, the method further comprises the step of obtaining the weight used for representing the passing limit height condition according to at least one of the first limit height information and the second limit height information. By adopting the embodiment, the weight for representing the passing limit height condition can be obtained according to at least one of the first limit height value information (such as the actual limit height value of the passing limit height object of the fixed class) and the second limit height value information (such as the limit height action range of the passing limit height object of the adjustable class), so that different weights can be obtained according to the detailed information of different limit height values of the limit height object, the navigation route screening requirements of different users can be matched, and the passing efficiency can be improved.
In one embodiment, the method further comprises obtaining the first value according to at least one of the first height-limiting value information and the second height-limiting value information. And combining the first value with the height limit adjustment value to obtain the weight for representing the passing height limit condition. The height limit adjustment value comprises at least one of a vehicle type, a vehicle weight, a vehicle allowed passing time period and a vehicle passing scene. According to the method and the device, in consideration of the situation of limiting the height of the height-limiting object, such as vehicle information of the vehicle, such as vehicle type, vehicle weight and the like, and the screening of navigation routes can be influenced by the vehicle allowed passing time period and the vehicle passing scene, the weight is required to be further optimized, so that the weight can be combined with the height-limiting adjustment value according to at least one of the first height-limiting value information (such as the actual height-limiting value of the fixed type of the passing height-limiting object) and the second height-limiting value information (such as the height-limiting action range of the adjustable type of the passing height-limiting object) so as to obtain more accurate weight to match the navigation route screening requirements of different users, and the passing efficiency is improved.
In one embodiment, a target navigation route is selected from a plurality of candidate navigation routes according to the weight for representing the traffic height condition, wherein the first mode comprises that the plurality of candidate navigation routes are respectively corresponding to the weight for representing the traffic height condition, the candidate navigation route with the minimum weight for representing the traffic height condition is determined as the target navigation route, and the second mode comprises that one candidate navigation route with zero weight for representing the traffic height condition exists in the plurality of candidate navigation routes, and the candidate navigation route is determined as the target navigation route. By adopting the embodiment, the navigation route screening requirements of different users can be matched in various modes, the candidate navigation route with the minimum weight can be selected as the target navigation route, or one candidate navigation route with zero weight (namely, the height limiting condition of the height limiting object does not exist) is selected as the target navigation route, and the passing efficiency is improved.
In one embodiment, the method further comprises obtaining wind control prompt information of navigation priority according to the weight used for representing the traffic limit height condition. By adopting the implementation mode, the wind control prompt information of the navigation priority can be obtained according to the weight used for representing the passing height limiting condition, if a user selects a target navigation route with the height limiting condition of a height limiting object, the passing efficiency is affected, and the wind control prompt information (such as alarm prompt information) can be sent.
The navigation route screening method provided by the embodiment of the present disclosure is illustrated below.
As for the passing height-limiting objects, the field measurement is mainly divided into two types, namely a passing height-limiting object of a fixed type and a passing height-limiting object of an adjustable type. Fig. 3-5 are schematic diagrams of a fixed class of traffic limit height objects in an application example according to an embodiment of the present disclosure, as shown in fig. 3, a fixed class of traffic limit height object (e.g., a fixed limit height lever) is present on a road section, a limited height indicator 301 "vehicle traffic over 2.2 meters" is set on the fixed class of traffic limit height object, S256 Jiang Longda bridge is a four-class bridge, vehicle traffic over 2.2 meters is prohibited, as shown in fig. 4, a fixed class of traffic limit height object (e.g., a fixed limit height lever) is present on a vehicle travel road section, limited height indicators are respectively set on the fixed class of traffic limit height object corresponding to different lanes (e.g., a first lane is set with a limited height indicator 401 "vehicle traffic over 2.2 meters", and a second lane is likewise set with a limited height indicator 402 "vehicle traffic over 2.2 meters", as shown in fig. 5 is set with a limited height indicator "vehicle traffic over 5 meters" is prohibited on the road section, a limited height indicator "vehicle traffic over 5 meters" is set on the fixed class of road section (e.g., a culvert or tunnel), a limited height indicator "vehicle traffic over 5 meters" is prohibited "is set on the limited height indicator" 6, a specific vehicle traffic limit height indicator "is set for a specific vehicle traffic over 1.2 meters" vehicle traffic limit height indicator "is set on the road section, a specific traffic limit height indicator (e.g., a limited height indicator is set on a specific vehicle is set on a road surface of 6, a vehicle is set on a road, and a vehicle is limited to a specific traffic level indicator, a vehicle is set on a road surface is no 2 meter, the limited height value variable quantity caused after the height adjustment is inconsistent with the height value measured in the field, so that the accuracy of navigation route planning is affected, a user drives a vehicle or an automatic driving vehicle, the traveling can reduce the passing efficiency according to the height value measured in the field, and even the road safety risk is generated.
In the application example, a height limiting model library can be established according to the actually measured passing height limiting objects, the passing height limiting objects are classified in the height limiting model library, the passing height limiting objects of fixed types and the passing height limiting objects of adjustable types are obtained, and the respective actual height limiting value action ranges of the two types of passing height limiting objects are recorded respectively, so that more accurate and safe data support is provided for planning of navigation routes, and the passing efficiency is improved.
1. Classification of height-limiting model libraries
1) The fixed type of passing height limiting objects comprise bridge bottoms, tunnel culverts, fixed height limiting rods, pedestrian overpasses, portal frames, memorial archways, billboards, camera/signal lamp cross bars and the like.
2) The adjustable class of passing height-limiting objects (namely, the non-fixed class of passing height-limiting objects) comprise lifting height-limiting rods, falling rod type height-limiting rods, flat-open type height-limiting rods and the like.
2. Actual height-limiting value range recorded in height-limiting model library
1) And recording fixed height limit values, such as 4.5m, 3m, 5m and the like, of the fixed class of passing height limit objects.
2) The adjustable class of traffic height limiting objects (namely, the non-fixed class of traffic height limiting objects) records the action range of actual height limiting values according to the field scene measurement result, such as a flat-open height limiting rod, wherein the field measurement height limiting indication is 3m, and the adjustable class of traffic height limiting objects can be opened to be completely free of height limitation, so that the adjustable class of traffic height limiting objects are recorded as a 'minimum height value: 0m and a maximum height value: 3 m'. If the height limiting rod is lifted, the height limiting indication measured in the field has 2 heights, namely 2.8m and 4.5m, the height limiting rod is recorded as a 'minimum height value of 2.8m and a maximum height value of 4.5 m'. It should be noted that, the range of the actual height limit value recorded in the height limit model library can be obtained through in-situ measurement, and also can be obtained through historical navigation data of vehicle running, for example, the vehicle height is 2.2m, and the road section where the lifting height limit rod is located, so that the record can be adjusted to be "the lowest height limit value is 2.2m, and the highest height limit value is 4.5m".
In this application example, the weight for representing the passing height limit condition may be calculated according to the classification of the height limit model library and the action range of the actual height limit value recorded in the height limit model library.
In this application example, the weight calculation may be further performed according to the classification of the height-limiting model library and the action range of the actual height-limiting value recorded in the height-limiting model library, in combination with the height limitation of the vehicle type (for example, the height of the vehicle of the middle-sized vehicle, the large-sized vehicle, the small-sized vehicle, the micro-sized vehicle, etc., and the height limitation of the specific scene, so as to obtain a more accurate weight value.
By adopting the application example, the classification of the height limiting model library is established, the action range of the actual height limiting value (such as the action range of the actual height limiting of the fixed class and the adjustable class) is recorded in the height limiting model library, and under the condition that two navigation routes with the same starting point and destination exist, the obtained weight value can be used for selecting the priority of the navigation route (such as the existence of the height limiting object on the navigation route, the low navigation priority and the like) according to the recorded action range of the actual height limiting value, so that the passing height limiting object of the fixed class and the adjustable class exists on the navigation route according to the weight value, and the target navigation route with high passing efficiency is screened out from a plurality of navigation routes. Furthermore, the wind control of the navigation route which is the risk of no passing can be known according to the weight value, so that wind control prompt information is sent out, a user can conveniently select a reasonable target navigation route, and the risk of no passing is avoided.

These program code may be provided to a processor or controller of a general purpose computer, special purpose computer, or other programmable data processing apparatus such that the program code, when executed by the processor or controller, causes the functions/operations specified in the flowchart and/or block diagram to be implemented. The program code may execute entirely on the machine, partly on the machine, as a stand-alone software package, partly on the machine and partly on a remote machine or entirely on the remote machine or server.
In the context of this disclosure, a machine-readable medium may be a tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device. The machine-readable medium may be a machine-readable signal medium or a machine-readable storage medium. The machine-readable medium may include, but is not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing. More specific examples of a machine-readable storage medium would include an electrical connection based on one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing.
To provide for interaction with a user, the systems and techniques described here can be implemented on a computer having a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to the user and a keyboard and a pointing device (e.g., a mouse or a trackball) by which the user can provide input to the computer. Other types of devices may also be used to provide interaction with the user, for example, feedback provided to the user may be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback), and input from the user may be received in any form, including acoustic input, speech input, or tactile input.
The systems and techniques described here can be implemented in a computing system that includes a background component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front-end component (e.g., a user computer having a graphical user interface or a web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such background, middleware, or front-end components. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include a Local Area Network (LAN), a Wide Area Network (WAN), and the Internet.
The computer system may include a client and a server. The client and server are typically remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. The server may be a cloud server, a server of a distributed system, or a server incorporating a blockchain.
It should be appreciated that various forms of the flows shown above may be used to reorder, add, or delete steps. For example, the steps recited in the present disclosure may be performed in parallel, sequentially, or in a different order, provided that the desired results of the technical solutions of the present disclosure are achieved, and are not limited herein.
The above detailed description should not be taken as limiting the scope of the present disclosure. It will be apparent to those skilled in the art that various modifications, combinations, sub-combinations and alternatives are possible, depending on design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present disclosure are intended to be included within the scope of the present disclosure.
