Exemplary method
Example one
The smart city accurate positioning method in the embodiment can be applied to mobile terminals, such as mobile phones and positioning terminal devices. Specifically, as shown in fig. 1, the smart city accurate positioning method includes the following steps:
and S100, coding each specific position in the urban road in advance.
In the embodiment of the invention, each specific position in the urban road needs to be coded in advance. For example, each road in the city is first coded once, for example, 310001, etc., and then each road is segment-numbered every 10 meters at a specific position to be secondarily coded, for example, 0001, etc., and then the process proceeds to step S200. Thus, multiple locations per road may have multiple codes.
Step S200, the generated codes are printed at the positions corresponding to the roads, and the positions corresponding to the codes are added to the map.
In the embodiment of the invention, each generated code is respectively printed at the corresponding position of the road, and the position corresponding to the code is added into the map. In this way, in the embodiment of the invention, a specific position of each road only corresponds to one unique code, each unique code is printed at the corresponding position of the road, and the position corresponding to the code is added into the map. The unique code of each position of the road has a one-to-one correspondence with the corresponding position in the map.
Step S300, when the current position needs to be positioned, scanning to obtain the coding information of the current position.
Therefore, when the invention is implemented, when a user needs to call a car on the road and needs to position the current position, the coding information of the current position can be obtained by scanning with a mobile phone. For example, taking a picture through a mobile phone and scanning the coded information of the current position.
S400, sending the coding information of the current position obtained by scanning to a positioning terminal;
when the step is implemented, sending the coding information of the current position obtained by scanning to a positioning terminal; the coding information of the current position can also be directly obtained by scanning through the mobile phone. And proceeds to step S500.
And S500, the positioning terminal obtains accurate positioning according to the acquired coding information of the current position.
Specifically, in this step, the positioning terminal obtains accurate positioning according to the obtained coding information of the current position. In the embodiment of the invention, the positioning terminal, such as a mobile phone, has a one-to-one correspondence relationship with the corresponding position in the map and corresponds to the specific position of the road through the unique code of each position of the road which is set in advance according to the acquired code information of the current position, so that the accurate positioning can be obtained through the acquired code information of the current position.
Example II,
The smart city accurate positioning method in the second embodiment of the invention can be applied to mobile terminals, such as mobile phones and positioning terminal equipment. Specifically, as shown in fig. 2, the smart city accurate positioning method according to the second embodiment includes the following steps:
and step S10, carrying out first coding on urban roads in advance, wherein one road corresponds to a unique code.
In the embodiment of the invention, the urban roads are coded for the first time in advance, and one road corresponds to a unique code. For example, existing roads are coded, and one road only has a unique code; the coding method can be according to the expression "S1 + S2", wherein S1 is a postcode (6 numbers), and people can know which area has higher readability through the postcode, and S2 is a concrete road (0000-.
Step S20, carrying out secondary coding on the specific position in each road;
this step is a secondary encoding of the specific location within each road. For example, a specific position in a road is encoded by: "S3 + S4", S3 represents the direction of the road, so only 1 number is needed and can be only 0 or 1; s4 shows the specific position on the road, which is represented by 4 numbers, and S4 can set the start position of the road to 0000, and increase by 1 every 10 meters in the extending direction.
Step S30, the primary code and the secondary code of each position are combined into a group of composite codes representing unique positions;
in an embodiment of the present invention, the primary code and the secondary code of each location are combined into a set of composite codes representing a unique location. For example, encoding as described above, "S1 + S2+ S3+ S4" constitutes a string of 15-bit numbers representing a unique position with an error of less than 10 meters.
Step S40 is to generate a corresponding position two-dimensional code representing the unique position from the composite code representing the unique position.
In this step, the composite code representing the unique position is generated into a corresponding position two-dimensional code representing the unique position. For example, as described above, the 15-bit digital composite code is used to generate a two-dimensional code, for example, as shown in fig. 3, a specific position on a certain road in west Li of Shenzhen city is shown.
And step S50, printing the generated position two-dimensional code and the corresponding composite code at the corresponding position of the road, and adding the corresponding position into the map.
In the embodiment of the invention, the generated position two-dimensional code and the corresponding composite code are printed at the corresponding position of the road, and the corresponding position is added into the map. For example, a composite code for generating the two-dimensional code and the 15-bit number is printed on a roadside (similar to roadside parking space numbers), or a positioning board is installed on the roadside or is printed on other existing boards, and then each position point is added into a map (such as a Baidu map/Gaode map).
And step S60, when the current position needs to be positioned, scanning to obtain the two-dimensional code coding information or the composite coding information of the current position.
In the embodiment of the invention, when the current position needs to be positioned, the two-dimensional code coding information or the composite coding information of the current position is obtained by scanning.
Step S70, sending the two-dimensional code coding information or the composite coding information of the current position obtained by scanning to a positioning terminal;
or acquiring the coding information of the current position according to scanning, positioning and sending the positioned position information to the second terminal.
And step S80, the positioning terminal obtains accurate positioning according to the acquired two-dimensional code coding information or composite coding information of the current position.
That is, in steps S70 and S80 of the embodiment of the present invention, the user may send the two-dimensional code coded information or the composite coded information of the scanned current position to the driver 'S positioning terminal through the mobile phone, and the driver' S positioning terminal obtains accurate positioning according to the obtained two-dimensional code coded information or the composite coded information of the current position. Specifically, according to the arrangement, the unique code of each position of the road has a one-to-one correspondence with the corresponding position in the map and corresponds to the specific position of the road, so that the accurate positioning can be obtained through the obtained code information of the current position.
Or, the invention can also obtain the code information of the current position at the user end according to the scanning to position, and then the user sends the positioned position information to the second terminal of the driver.
The two-dimensional code sharing method and the device can realize that the passenger can share the position of the two-dimensional code at the current position of the code or directly send 15 digits to the driver, and the driver can obtain accurate positioning. Accurate positioning can be obtained at a low cost.
When the invention is implemented, two positioning modes can be realized, 1, a passenger directly sends a position two-dimensional code to a driver after scanning the code by using a mobile phone, and the driver opens a map for positioning after receiving the position two-dimensional code; and 2, after the passenger scans the codes, the passenger can accurately position the specific position on the mobile phone through the position two-dimensional code, and then the specific position information of the positioning is sent to the driver.
In a further embodiment, the 15 numbers (i.e. position codes) — > and the corresponding two-dimensional codes (15 numbers (i.e. position codes) generated by the invention can be mutually converted, and the two-dimensional codes are generated in order to facilitate the code scanning of the mobile phone) — > position information (at the server, the 15 numbers (i.e. position codes) are in one-to-one correspondence). The purpose of the driver is to obtain position information, the user can send 15 coded numbers or position two-dimensional codes, the app can be converted into the position information after the driver terminal receives the position information, and the driver can directly obtain the position information after the user sends the position information.
Therefore, the invention obtains more accurate position than the existing GPS/Beidou positioning system through the accurate positioning of the codes, and provides convenience for the use of users. The invention can conveniently scan the code through the two-dimensional code and automatically send the position, and meanwhile, the 15-digit digital code has readability, low realization cost and high positioning precision.
The invention can be applied to smart cities. The smart city is a new stage of informatization development and is an innovative mode of city development. The method fully embodies the core concept of human-oriented and embodies the construction ideas of large integration, large concentration and high sharing.
