In the following detailed description of the present disclosure, certain specific details are set forth. It will be apparent to those skilled in the art that the present disclosure may be practiced without these specific details. Well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present disclosure.
Further, those of ordinary skill in the art will appreciate that the drawings provided herein are for illustrative purposes and are not necessarily drawn to scale.

Generally, in the prior art, when a building is modeled, the following two modes are mainly adopted, namely, a point cloud model is generated by scanning the interior of the building by 360 degrees through mapping equipment; and secondly, manually establishing a model through mapping data or software according to design data.
Specifically, in the first mode, the point cloud model has the advantages that abundant point information can be acquired through the point cloud scanning system, but dead corners can occur in the point cloud model in the building process due to various shelters and complex structures in the building, so that the point cloud model is incomplete; the characteristic point information of equipment and facilities is difficult to obtain from a large amount of point information, so that the application limit is large, and a point cloud scanning system needs more equipment and is high in price, so that the establishment of a point cloud model needs high cost; in the second mode, the manual modeling through software is actually a redrawing process through mapping data or design data, so that the accuracy and readability of the mapping data or the design data affect the result of the model, and further the mapping data or the design data are required to be high in accuracy and strong in readability, if the design data are missing or different from the actual building, the field survey needs to be performed to describe supplementary data, a large amount of human resources and time are consumed, and although the cost is low, errors are prone to occur in the manual modeling process. Therefore, how to model a building quickly, accurately and at low cost is a problem to be solved at present.
In the embodiment of the invention, in order to solve the above problems, a method for mapping data processing is provided, by which real building information, such as core information of equipment, facilities and pipelines, can be recorded quickly and accurately, and then the information is converted into a unified coordinate system through a geometric algorithm, so that a model can be created quickly.
In the embodiment of the present invention, fig. 1 is a flowchart of a method for mapping data processing according to the embodiment of the present invention. As shown in fig. 1, the method specifically comprises the following steps:
and S100, calibrating the position coordinates of any group of positioning base stations in a unified coordinate system.
Specifically, the any one set of positioning base stations includes at least two positioning base stations, and the positions of the positioning base stations are variable.
In one possible implementation, multiple sets of positioning base stations may be calibrated in a unified coordinate system; assuming that the unified coordinate system is determined according to a building with five floors, when the model of the building is drawn, a part of the building can be drawn by setting one group of positioning base stations, therefore, when the building with five floors is drawn, the positions of the positioning base stations need to be set many times, a part of data can be obtained by setting one group of positioning base stations each time, and data of the whole building with five floors can be obtained by setting many times, as shown in fig. 2, two positioning base stations are set in any floor of the building.
And S101, determining a corresponding measurement coordinate system according to the position coordinates of any group of positioning base stations.
Specifically, assuming that the measurement coordinate system determined according to the positions of any one group of positioning base stations is a three-dimensional coordinate system as shown in fig. 3, and the three axes are the x axis, the y axis and the z axis, respectively, according to step S100, since the positioning base stations are calibrated in the unified coordinate system, the measurement coordinate system and the unified coordinate system have a certain conversion logic, that is, data in the measurement coordinate system can be converted into the unified coordinate system.
In the embodiment of the present invention, the unified coordinate system is also a three-dimensional coordinate system.
And S102, determining a measuring tool coordinate system of the measuring tool in the measuring coordinate system.
In the embodiment of the present invention, after a group of positioning base stations is determined, a measuring tool is set in a range covered by the group of positioning base stations, and a plurality of groups of measuring coordinate systems can be set under each measuring coordinate system, where the measuring coordinate system is determined according to the measuring tool, as shown in fig. 4, which indicates a relationship between the measuring tool coordinate system and the measuring coordinate system, and the measuring tool coordinate system is also a three-dimensional coordinate system.
In the embodiment of the invention, the measuring tool comprises the electronic compass, the gyroscope, the space positioning equipment and the distance measuring equipment, and the space positioning equipment is arranged in the measuring tool, so that the position of a coordinate system of the measuring tool in a coordinate system of the measuring tool can be determined, and further, a certain conversion logic between the coordinate system of the measuring tool and the coordinate system of the measuring tool can be determined, namely, data under the coordinate system of the measuring tool can be converted into a unified coordinate system.
Optionally, before measuring the measured target, the initial coordinates of the measuring tool need to be specified in the measurement coordinate system; and initializing the posture of the measuring tool, and determining a measuring tool coordinate system corresponding to the measuring tool. Specifically, the step of calibrating the initial coordinates of the measuring tool under the measurement coordinate system specifically includes: determining the initial coordinate of the measuring tool according to the positioning label of the measuring tool in the measuring coordinate system; the initializing the posture of the measuring tool specifically comprises: initializing an electronic compass and a gyroscope in the measuring tool.
And step S103, acquiring first measurement data of the measured target under the measuring tool coordinate system.
Specifically, the first measurement data includes a north declination angle and a vertical declination angle on a horizontal plane, and a distance from the measuring tool to the measured target.
In a possible implementation manner, the north declination angle on the horizontal plane is determined according to an electronic compass, the vertical declination angle is determined according to a gyroscope, the distance from the measuring tool to the measured target is determined according to a distance measuring device, the measuring device may be a laser distance measuring device, and the embodiment of the present invention does not limit the north declination angle on the horizontal plane.
For example, as shown in fig. 5, the distance measuring coordinate system is a schematic diagram of when the measuring target is measured under the measuring coordinate system, where the origin of the measuring coordinate system is the position of the measuring tool, the distance from the measuring tool to the measuring target is 1900mm, the north declination angle on the horizontal plane is 48 °, and the vertical declination angle is 56 °, which is only an exemplary example.
And step S104, converting the first measurement data into second measurement data in the measurement coordinate system.
Specifically, the first measurement data is converted into second measurement data in the measurement coordinate system through geometric calculation.
And step S105, converting the second measurement data into third measurement data in the unified coordinate system.
Specifically, the second measurement data is converted into third measurement data in the unified coordinate system through geometric calculation.
And S106, drawing a model according to the third measurement data.
In particular, the model generated from the third measurement data is a model of a building with a height of five stories in the example.
In the embodiment of the invention, after the measuring tool finishes measuring the measured target in one area each time, the measuring tool is moved to other positions to continuously acquire new first measurement data, and then the new first measurement data is converted into a plurality of third measurement data.
In the embodiment of the invention, after the measuring tool finishes the measurement of all the measured targets in one measuring coordinate, a group of positioning base stations is moved to other positions, for example, after the measurement of one floor in a building with the height of five floors is finished, the group of positioning base stations is moved to two floors, and the like, so that the measurement of each floor in the building with the height of five floors is finished. The position of the measuring tool is moved for multiple times in each floor to complete the measurement of each floor, all the acquired data are converted into a unified coordinate system in the above mode, and finally the model corresponding to the building with the five floors is drawn.
In the embodiment of the invention, because the positioning base station is adopted, the indoor positioning can be continued through the positioning base station without depending on equipment such as a map or a GPS (global positioning system) and the like to determine the measured position, and further, the data conversion is completed.
In the embodiment of the invention, the position coordinates of any group of positioning base stations are calibrated in a unified coordinate system; determining a corresponding measurement coordinate system according to the position coordinates of any group of positioning base stations; determining a measuring tool coordinate system of the measuring tool in the measuring coordinate system; acquiring first measurement data of a measured target under the measuring tool coordinate system; converting the first measurement data into second measurement data under the measurement coordinate system; converting the second measurement data into third measurement data under the unified coordinate system; and drawing a model according to a plurality of the third measurement data. By the method, the first measurement data of the measured template can be rapidly and accurately acquired through the measuring tool, then the data of the drawn model is generated through data conversion, and finally the model is drawn, so that the modeling cost is reduced, and the method is rapid and accurate.
