Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a three-dimensional navigation method in a building according to the present invention.
In a first embodiment, the method for three-dimensional navigation within a building comprises the steps of:
step S10: and acquiring target position information to be navigated and current position information.
It should be noted that, the execution subject of the embodiment is a three-dimensional navigation device in a building, and may also be other devices that can implement the same or similar functions, such as a mobile device.
In this embodiment, when navigating through a map application program, a user inputs a target location through a navigation setting interface, obtains target position information to be navigated according to the input target location, and when obtaining the target position information, establishes a preset building three-dimensional map model through the target position information.
In the concrete implementation, a more accurate map model is obtained by firstly obtaining data information of a building, obtaining a three-dimensional model of the building according to the data information and then obtaining a preset three-dimensional map model of the building according to the three-dimensional model of the building.
It is understood that a plurality of small base stations are arranged in a building, the small base stations cover a preset area by radiating base station signals, the small base stations are provided by mobile operators, and the coverage area is small, so that the small base stations are used for communication support in various complex environments. In the 4G era, small base stations have been used, while in the 5G era, the 5G base stations are distributed in units of 10 meters, and in some places, even one base station is present, thereby providing more accurate positioning information.
As shown in fig. 3, the small cell covers a preset area with a base station signal, so as to realize full coverage of the signal.
It should be noted that the preset area is an area covered by a base station, and when the current user travels into the preset area, the current location information can be determined through the small base stations arranged in the preset area, so that the user can be accurately located under the condition of weak signals.
Step S20: and mapping the current position information and the target position information on the preset building three-dimensional map model, and obtaining path node information through the preset building three-dimensional map model.
In this embodiment, in order to obtain more accurate navigation information, effective navigation information may be generated according to the node information by acquiring effective node information.
In a specific implementation, the current position information and the target position information are mapped on the preset building three-dimensional map model, and route node information is obtained through the preset building three-dimensional map model, so that the key point information of the generated route is obtained.
Step S30: and generating a target navigation path according to the path node information, and displaying the target navigation path.
According to the scheme, the target position information to be navigated and the current position information are acquired; mapping the current position information and the target position information on a preset building three-dimensional map model, and obtaining path node information through the preset building three-dimensional map model; and generating a target navigation path according to the path node information, and displaying the target navigation path, so that effective path node information is obtained through the established three-dimensional map model of the building, and more accurate navigation in the building is realized according to the path node information.
Referring to fig. 4, fig. 4 is a flowchart illustrating a second embodiment of the method for three-dimensional navigation in a building according to the present invention, and the second embodiment of the method for three-dimensional navigation in a building according to the present invention is proposed based on the first embodiment illustrated in fig. 2.
In the second embodiment, before the step S20, the method further includes:
step S201, calling a preset scanning device, obtaining scanning data through the preset scanning device, and processing the scanning data by adopting a proximity algorithm to obtain a three-dimensional structure model.
In this embodiment, in order to generate a three-dimensional map, a three-dimensional structure model is first generated, the preset scanning device may be a laser scanning device, and may also be other devices that can achieve the same or similar functions.
In a specific implementation, the scanning of the three-dimensional structure of the building is completed inside the building by using a laser cloud point scanning technology, approximate data of the building structure is obtained through computer data processing, and a three-dimensional structure model is constructed through the approximate data.
It should be noted that, the building three-dimensional model generation needs to further process the measured data, generate a rough model of the building by using a proximity algorithm, and finally map the model to obtain model data of the building.
Step S202, acquiring preset identification information, and importing the preset identification information into the three-dimensional structure model to obtain a three-dimensional map model of the preset building.
It should be noted that the preset identification information includes channel data, marker data, and floor data, and the channel data, the marker data, and the floor data are imported into the three-dimensional structure model to obtain a preset building three-dimensional map model.
Further, the step S202 includes:
acquiring channel data, marker data and floor data, and importing the channel data, the marker data and the floor data into the three-dimensional structure model; and acquiring coordinate data corresponding to the channel data, the marker data and the floor data, and corresponding the coordinate data to the three-dimensional structure model to generate the preset building three-dimensional map model.
In the embodiment, the three-dimensional map is generated by inspecting the real field of the building, importing available channel data, marker data, floor data and the like in the building into a building model, generating three-dimensional coordinate data of the building corresponding to a three-dimensional space, and finally generating the three-dimensional map for guiding the passage of a user.
According to the scheme, the building three-dimensional map model is generated through the channel data, the marker data and the floor data information on the basis of the building three-dimensional model, and therefore the more accurate three-dimensional navigation model is generated.
Referring to fig. 5, fig. 5 is a schematic flow chart of a third embodiment of the three-dimensional navigation method in a building according to the present invention, and the third embodiment of the three-dimensional navigation method in a building according to the present invention is proposed based on the first embodiment or the second embodiment.
In a third embodiment, a plurality of base stations are distributed in the building, and the base stations cover a preset area by radiating base station signals, and the acquiring current location information includes:
searching signal intensity information corresponding to each base station in a preset area; selecting at least three target base stations from the searched base stations; determining distance information with each target base station according to the signal intensity of each target base station; and determining current position information according to the distance information between the current position information and each target base station and the position of each target base station.
In order to realize more accurate positioning and navigation, small base stations are arranged in a building, are provided by mobile operators, have small coverage and are used for communication support in various complex environments.
The embodiment is based on small base stations densely distributed in a building, and the small base stations are used for assisting positioning. As shown in the schematic base station positioning diagram of fig. 6, when a user moves with a mobile device in the coverage area of a dense base station, the device may search for a plurality of base station signals, and may estimate the relative distance from the device to each base station according to the signal strength of 3 or more than 3 base stations that are searched, and since the relative distance from the base station is known, the location information of the mobile device may be confirmed.
Further, the acquiring current location information includes: when signal intensity information corresponding to each base station in a preset area is not searched, acquiring traveling direction information and current speed information by calling an acceleration sensor; and determining current position information according to the previous position information, the traveling direction information and the current speed information.
The acceleration sensor may be a gyroscope sensor and an electronic compass mounted on the mobile device, so that the traveling direction information of the user can be confirmed, and inertial navigation can be realized through the gyroscope for positioning in a weak signal area.
Further, the step S20 includes:
step S203, mapping the current position information and the target position information on the preset building three-dimensional map model to obtain coordinate point information of direction change.
It should be noted that, mapping the base station position coordinate data and the user positioning coordinate data to corresponding points of the three-dimensional map, when the user requests navigation to the target position at the current position, searching an available path from the starting point to the target position in the three-dimensional map by a traversal method, and listing the shortest paths for the user to select. As shown in the path selection diagram of fig. 7, two routes from the starting point a to the ending point B are set to be reachable, and the navigation system lists the two routes at the same time, so that the user can select the route according to the requirement.
And step S204, taking the coordinate point information as the path node information.
Continuing with FIG. 7, the active paths are A-1-4-B and A-1-2-3-4-B, where 1, 2, 3, 4 are the key nodes in the path. At the node, the traversal algorithm needs to decide a proper path, and if the decision is not appropriate, a-1-4-3-2-1-4-B and other similar invalid paths may occur. Therefore, there is a need to introduce path planning, and the key points of the planning include: an environment model: a three-dimensional map containing all channel information; and (3) node: all points in the environment model, which need to change two or more directions, are regarded as key nodes, so that key node information is obtained.
Further, the step S30 includes:
generating a reference navigation path by adopting a search algorithm according to the path node information; performing invalid path evaluation on the reference navigation path through a decision algorithm; and obtaining a target navigation path according to the evaluation result, and displaying the target navigation path.
It should be noted that, in order to improve the effectiveness of the path, a search algorithm is adopted to finally generate the path by connecting the nodes between a and B. To prevent invalid paths, the decision algorithm must prevent "loops", i.e., a-1 is reasonable and 1-a is considered "loop", in the route from a to B, which should be rejected first. In addition, the decision algorithm should avoid duplication, such as the A-1-4-3-2-1-4-B route, which is considered invalid when a 1-4 duplication occurs for the first time.
Meanwhile, the navigation system supports a user to record own path data by using the mobile equipment, and after the user shares the path to the cloud platform, when other users initiate navigation requests with the same starting point and the same end point, the navigation system can recommend other available paths for the user except algorithm planning.
In this embodiment, the recorded path may also be used to help improve the path planning algorithm, and as the amount of data increases and improves, more reliable navigation may be achieved.
According to the scheme, the reference navigation path is generated by adopting a search algorithm according to the path node information; performing invalid path evaluation on the reference navigation path through a decision algorithm; and obtaining a target navigation path according to the evaluation result, and displaying the target navigation path, thereby improving the effectiveness of the path.
In addition, an embodiment of the present invention further provides a storage medium, where the storage medium stores a three-dimensional navigation program in a building, and the three-dimensional navigation program in the building implements the steps of the terminal network accessing method described above when being executed by a processor.
Since the storage medium adopts all technical solutions of all the embodiments, at least all the beneficial effects brought by the technical solutions of the embodiments are achieved, and no further description is given here.
