Example one
Fig. 1A is a flowchart of a building identification method according to an embodiment of the present invention, where the building identification method may be performed by a building identification apparatus according to an embodiment of the present invention, and the building identification apparatus may be implemented in software and/or hardware. The method specifically comprises the following steps:
and S110, receiving a reading request of a user.
The reading request may be text information or voice information sent by the user to the cloud server through the mobile phone, or a virtual key including a "reading request" is selected, and the embodiment does not limit the expression of the reading request.
Specifically, the building is readable, and a new building-understanding window is built for people. The readable modes at least comprise a multilevel management mode, for example, when an administrative staff needs to read the building information, management information such as enterprise information, talent information, tax of the enterprise, power utilization management and the like of living in the building can be displayed, when a professional staff needs to read the building information, a building designer of the building, a design background, a design style and related introduction of the designer can be displayed, when a non-professional staff reads the building, visiting culture information and the like of the building can be displayed, and people can also know various contents of the current building at any time by using a mobile phone APP as a medium. For example, a software program containing building information of a smart city can be logged in to send a reading request of the current building, so that all-around information about the current building can be known. Specifically, for example, if a visitor visits a historic building in a city, and when the visitor walks into the historic building, the visitor sends a reading request, so that the visitor can know a relatively complete historic building introduction, can see the historic building introduction and can also hear a voice explanation of the historic building, and thus people can know the historic building more conveniently.
And S120, determining a plurality of pieces of facade information of a plurality of buildings facing the user according to the position information of the user terminal and each base station.
The user terminal may be an electronic product such as a mobile phone, an iPad, a notebook computer, and the like, and preferably, the user terminal related in this embodiment is a mobile phone. A base station, i.e., a common mobile communication base station, is a form of a radio station, which refers to a radio transceiver station for information transfer with a mobile phone terminal through a mobile communication switching center in a certain radio coverage area. Wireless base stations are classified into four categories, including macro base stations, micro base stations, pico base stations, and femto base stations. Preferably, the base station involved in this embodiment may be a pico base station, for example, a 5G pico base station. The position information of the user terminal and each base station can be the specific coordinate information of the mobile phone and the 5G pico-base station in the current space. Facade information refers to all of the perimeter protection of the building except the roof.
Specifically, the construction of the smart city can be configured with 5G pico base stations on buildings which need the "readable" function, and one or more 5G pico base stations can be configured on the same building according to the area of the building. The building group in the same area can be flexibly configured with the 5G pico-base station according to the requirements of each building. When the user walks into the range covered by the 5G pico base station, the user sends a reading request, and the position information of the user terminal and the 5G pico base station can be obtained. And if the position of the user is the coverage range of the plurality of 5G pico-base stations, acquiring the position information of the user terminal and the plurality of 5G pico-base stations.

For example, fig. 1B is a schematic diagram of an exemplary building identification according to an embodiment of the present invention. As shown in fig. 1B, the system includes a building a, a building B, and a building C, wherein each building is configured with a 5G pico-base station, a, B, and C. The user D arrives at the position E and is just in the coverage range of the three pico-base stations, so when the user D sends a reading request to the cloud server, the cloud server not only acquires the position of the user D, but also acquires the position information of the three base stations of the building A, the building B and the building C, and acquires the relative view angle information Da, Db and Dc corresponding to the three buildings. And the cloud server can determine three pieces of facade information of the building A, the building B and the building C facing the user according to the complete facade information of the building A, the building B and the building C contained in the building model library and by combining the relative view angle information Da, Db and Dc.
S130, determining target facade information matched with the image information uploaded by the user in the plurality of facade information, and identifying a building corresponding to the target facade information as a target building.
Wherein, the target building refers to a building that the user wants to know. For example, after the user sends a reading request, when the user wants to know a certain building, the user can take a picture of the building by using a mobile phone.
Optionally, the determining, among the plurality of pieces of facade information, target facade information that matches the image information uploaded by the user in a consistent manner includes: respectively determining similarity values between each piece of facade information and the image information uploaded by the user; and taking the facade information corresponding to the highest similarity value as target facade information.
In the prior art, the building readable way can be to perform pattern recognition on key parts of a specific building with salient features, but only individual buildings are applicable and limited by the photographing angle and the building features must be salient, but the embodiment of the invention can solve the problem that the building features are not obvious in the pattern recognition scanning in a coordinate-assisted image recognition way.
As shown in fig. 1B, if the user wants to know the building B in detail, the user photographs the building B as image information and uploads the image information to the cloud server, the cloud server performs image matching on the received image information and the previously processed three pieces of facade information to respectively determine similarity values between the building a, the building B, the building C and the image information uploaded by the user, and the facade information with the highest similarity value is used as target facade information, that is, the facade information of the building B, so as to successfully identify the building B.

And S250, playing the readable information corresponding to the target building under the condition of the user type.
The readable information includes complete information of the building, and may be text information, voice information or video information.
Specifically, the embodiment of the present invention may also set a user type in the mobile phone APP, for example, a government leader, a tourist, a consumer, an investor, a tenant, and the like, and then provide different types of readable information according to different types of requirements. Specifically, for example, when the user is a visitor, the readable information may be information related to the visitor, such as historical building time, famous historical time, play notes, etc. of the building; when the user is an investor, the readable information may be information related to the investor, such as the number of occupied businesses of the building, the industry to which the business belongs, the configuration of catering medical conditions, and the like.
Optionally, before receiving the reading request of the user, the method further includes: constructing a digital twin model of a current region building, wherein the digital twin model of the current region building comprises the building model library.
