Description
Technical Field
[0001] The present invention relates to the technical field of real-scene three-dimensional data processing, and in particular to a real-scene three-dimensional parameterization method and system. Background Art
[0002] Real scene 3D technology, full name real scene 3D digital technology, can construct a digital space that maps "reality" and is a cutting-edge digital mapping method. In actual work, real scene 3D technology uses high-precision measurement and scanning equipment and technical means such as laser radar, photogrammetry, and satellite remote sensing to capture the geological features of the real world and detailed information such as the shape, size, position, and surface texture of objects, and converts them into structured, semantic, and human-machine compatible understanding and real-time perception of the Internet of Things. Since the measurement data comes from the real world, the 3D models generated by real scene 3D technology are highly realistic in shape, scale, and texture, retaining the realism and three-dimensionality of the real world.
[0003] However, although the real-scene 3D technology can truly and intuitively reflect the real physical space form of an object in the form of a 3D model on a computer, the 3D model files produced by the existing technology do not contain parameter information outside the 3D space. Therefore, in the fields of engineering construction, operators are required to further identify and extract parameter information such as object category and engineering progress from the real-scene 3D model through recognition and extraction technologies such as image recognition. Not only is the work efficiency low, but the accuracy of the extracted parameter information is also low, which cannot meet the demand for parameter information in engineering construction management. Summary of the invention

According to the following description, the advantages and features of the present invention will be clearer.

[0042] like Figure 1 As shown, the present invention provides a real-scene three-dimensional parameterization system, which includes an input module, a control network module, a parameter layer module and an output module. The input module is used to input data, for example, it can be used to input a real-scene three-dimensional file. The output module is used to output data, for example, it can be used to output a real-scene three-dimensional parameterization file. The control network module includes a plane grid unit, a height stratification unit and a coordinate conversion unit, and the parameter layer module includes a grid classification unit, a formula unit and an editing unit. The specific functions of these modules and units will be further described below.
[0043] like Figure 2 As shown, the present invention provides a real-scene three-dimensional parameterization method, which includes step S1, inputting a real-scene three-dimensional file.
[0044] Specifically, in step S1, the real scene 3D file enters the real scene 3D parametric system through the input module and is converted into a special file format that can be read and displayed by the system for further processing by other modules and units. The real scene 3D file includes but is not limited to file formats such as obj, fbx, and osgb. By supporting the real scene 3D files in multiple file formats, it is helpful to improve the applicability and practicality of the real scene 3D parametric system.
[0045] Furthermore, the real-scene three-dimensional parameterization method also includes step S2, establishing a blank output file, and establishing a control network based on the real-scene three-dimensional file to divide the real-scene three-dimensional file into multiple three-dimensional unit grids, and establishing a file basic unit in the blank output file corresponding to each of the three-dimensional unit grids.
[0046] Specifically, in step S2, the blank output file can be established through the control network module, and the control network can be established according to the real-scene three-dimensional file. More specifically, the blank output file corresponding to the real-scene three-dimensional file input through the input module can be newly established in the plane grid unit, and the format of the blank output file is csv format. By additionally establishing the blank output file to form the real-scene three-dimensional parameterized file, there will be no interference or damage to the original real-scene three-dimensional file, which has a good data protection effect and is convenient for staff to perform management and maintenance work.
[0047] In the plane grid unit, the operator can input appropriate plane grid information according to the real-life three-dimensional file. The plane grid information includes the origin plane coordinates, the unit grid plane coordinates and the side length unit information. Among them, the origin plane coordinates include the origin x coordinate and the origin y coordinate; the unit grid plane coordinates include the unit grid x coordinate and the unit grid y coordinate. According to actual needs, the side length unit information can be meters, decimeters or centimeters. By inputting the plane grid information, the x coordinate and y coordinate of each point in the real-life three-dimensional file on the plane can be determined by determining the origin x coordinate and the origin y coordinate on the plane, that is, the unit grid x coordinate and the unit grid y coordinate.
[0048] Similarly, in the height layering unit, the operator can input appropriate height layering information layer by layer from the bottom of the real scene 3D file to the top according to the real scene 3D file and the plane network that has been established through the plane grid information. The height layering information includes the bottom layer height coordinate, the unit grid height coordinate, the total number of layers and the number of unit grid layers. By determining the bottom layer height coordinate, the Z coordinate of each point in the real scene 3D file in the height direction, that is, the unit grid height coordinate, can be determined.
[0049] By combining the height layer information with the plane grid information, the real scene 3D file can be divided into a plurality of 3D unit grids, and a file basic unit is established in the blank output file corresponding to each 3D unit grid, so as to facilitate the storage of parameter information of each 3D unit grid. The file basic unit can store parameter information related to the real scene 3D file and the 3D unit grid, such as the real scene 3D file number, the coordinate file number, the side length unit information, the total number of layers, the unit grid plane coordinates, the unit grid height coordinates and the unit grid layer number.
[0050] As described above, the present invention inputs plane grid information according to the real-scene three-dimensional file through the plane grid unit of the control network module. And further inputs height stratification information according to the real-scene three-dimensional file and the plane grid information through the height stratification unit of the control network module. In combination with the plane grid information and the height stratification information, the real-scene three-dimensional file is divided into multiple three-dimensional unit grids, and a file basic unit is established in the blank output file corresponding to each of the three-dimensional unit grids, thereby forming a complete control network. In addition, in order to optimize the blank output file and improve the output accuracy and subsequent work efficiency, the blank output file can also be coordinate-converted by the coordinate conversion unit.
[0051] Furthermore, the real-scene three-dimensional parameterization method also includes step S3, adding grid classification information and parameterization information to the blank output file according to the real-scene three-dimensional file and the control network to form the real-scene three-dimensional parameterization file.
[0052] Specifically, the grid classification information and the parameterization information may be added to the blank output file through a parameter layer module to form the real-scene three-dimensional parameterized file.
[0053] For example, in the grid classification unit, the operator can input appropriate grid classification information to each of the three-dimensional unit grids according to the real-life three-dimensional file, that is, add a grid classification number to the file basic unit of each of the three-dimensional unit grids. Each of the grid classification numbers represents a pre-numbered object. The pre-numbered object can be any object included in the real-life three-dimensional file, such as land, vegetation, water, reinforced concrete, people, machinery, etc., and the present invention is not limited to this. Preferably, when the three-dimensional unit grid includes multiple pre-numbered objects, multiple corresponding file basic units can be established for the three-dimensional unit grid, so as to facilitate the staff to view and manage parameters.
[0054] Similarly, in the formula unit, the operator can select two of the three-dimensional unit grids according to the real-scene three-dimensional file, add formula parameter information to the at least two three-dimensional unit grids, that is, add a call formula number to the file basic unit of the at least two three-dimensional unit grids. Each of the call formula numbers represents a pre-numbered calculation formula.
[0055] Finally, the real-scene three-dimensional parameterization method may further include step S4, outputting a real-scene three-dimensional parameterized file corresponding to the real-scene three-dimensional file input by the input module through the output module. The file format of the real-scene three-dimensional parameterized file is the same as that of the blank output file, both of which are in csv format. The present invention converts a large real-scene three-dimensional file into a small real-scene three-dimensional parameterized file that only records parameter information through a systematic process, which is easy to use, can achieve lightweight files, and is easy to transmit and use, which is conducive to further improving work efficiency and reducing costs.
[0056] If there is already a real-scene three-dimensional parametric file generated by the control network module and the parameter layer module or output by the output module. When the real-scene three-dimensional parametric file needs to be updated, an update editing number can be added to the real-scene three-dimensional parametric file through the update editing unit. Specifically, in the update editing unit, the operator can select one or more steps of the above-mentioned steps of generating the real-scene three-dimensional parametric file in the update editing unit according to the updated version of the real-scene three-dimensional file, so as to avoid tedious and repetitive work, reduce the burden on the staff, and improve work efficiency. When updating the real-scene three-dimensional parametric file, the update editing unit can add an update editing number to the file basic unit of the real-scene three-dimensional parametric file, so as to facilitate the management and maintenance of the staff.
[0057] The following will further illustrate the working principle of the real scene three-dimensional parameterization method and system by taking the changes of the information stored in the basic unit of the file as an example.
[0058] Specifically, the basic structure of the basic file unit can be (a, b, c, d, e, f, x, y, z, za, zb), that is, the basic file unit can be used to store the above information parameters. Among them, a represents the real scene 3D file number; b represents the coordinate file number, c represents the side length unit information; d represents the grid classification number; e represents the call formula number; f represents the update edit number; x represents the unit grid x coordinate; y represents the unit grid y coordinate; z represents the unit grid height coordinate; za represents the total number of layers; zb represents the unit grid layer number.
[0059] First, the blank file is generated in the control network module. When it is output through the plane grid unit, the information included in the basic unit of the file is (a, b, c, x, y). After further output through the highly layered unit, the information included in the basic unit of the file is (a, b, c, x, y, z, za, zb). When the blank output file enters the parameter layer module, for example, when it is output through the grid classification unit, the information included in the basic unit of the file is (a, b, c, d, x, y, z, za, zb). After further output through the formula unit, the information included in the basic unit of the file is (a, b, c, d, e, x, y, z, za, zb). If the real-life three-dimensional parametric file has also been updated through the update editing unit, the information included in the basic unit of the file is (a, b, c, d, e, f, x, y, z, za, zb).
[0060] As described above, the present invention can form the real-scene three-dimensional parametric file through a systematic process, and add parameters that need to be used and managed to the real-scene three-dimensional parametric file according to the management requirements of actual engineering construction. The structure is simple and easy to use. When using the real-scene three-dimensional parametric method and the real-scene three-dimensional parametric system, the staff only needs to master the relevant knowledge in the field of engineering construction and be familiar with the relevant operation process of the real-scene three-dimensional parametric system, without additional learning of relevant knowledge in the field of computer science or software development. It is conducive to reducing the burden on the staff and further improving work efficiency.
[0061] The real-scene three-dimensional parameterization method and system of the present invention converts a real-scene three-dimensional file that does not contain parameter information other than the three-dimensional space into a real-scene three-dimensional parameterized file with multiple parameter information. The parameters are highly accurate and easy to view, which can fully meet the management needs of engineering construction, reduce the burden on staff, and effectively improve work efficiency.
