For example, a boundary line of a building object is drawn manually, and the resulting boundary line of the object is used to divide the building. The segmented building is then singulated by modeling software. However, in the case where a large number of buildings need to be integrated, if the related art is adopted, the user needs to perform a large amount of data processing work, which is heavy.

Detailed Description
Before describing the embodiments of the present application, the terms referred to in the embodiments of the present application are explained:
GeoJSON: GeoJSON is a format that encodes various geographic data structures. In a geographic information data exchange format based on JavaScript's object representation, a GeoJSON object can represent a geometric feature or a set of features. Here mainly a geometric collection of support surface data.
Protocol buffers (pbf): the method is a method for serializing structural data which is independent of a language-independent platform and can be expanded, and can be used for (data) communication protocols, data storage and the like. Compared with other sequence structures, pbf is more flexible and efficient, and the automation mechanism of pbf is smaller, faster and simpler.
Web graphics library (WebGL): WebGL is a three-dimensional (3D) drawing protocol, which allows JavaScript to be combined with open graphics library (OpenGL ES)2.0 for embedded systems, and by adding a JavaScript binding of OpenGL ES2.0, WebGL can provide hardware 3D acceleration for hypertext markup language 5 (HTML 5) Canvas, and developers can smoothly show 3D scenes and models in browsers by means of display cards.
Oblique photography data: the method is characterized in that a plurality of sensors are carried on one aircraft, and image data of a target entity are acquired from a plurality of different angles. The image data may be used to rapidly reconstruct a three-dimensional model (which may also be referred to as a three-dimensional real-world model) of the target entity.
It should be noted that, in the embodiment of the present application, the oblique photography data of the entity may include a plurality of coordinate data of the entity, and the plurality of coordinate data may constitute the shape of the entity. For example, a geometric model of the entity can be obtained by concatenating a plurality of coordinate data.
And (3) performing monomer conversion: the singleton is a single object entity which is managed separately and is an object entity which can be selected, that is, when a user clicks an independent object entity which wants to be managed, the object entity can be highlighted and the attribute information of the object entity is output. Only with the ability to be individualized, data can be managed for use, not just for viewing. For artificial modeling, such as the model built by 3Dmax, the monomer is an easy matter to implement. That is, in the process of artificial modeling, objects that need to be managed separately are naturally made as separate models, separated from other objects.
To realize the singleization of the oblique photography data, the following two methods can be used:
the method I comprises the following steps of artificial modeling:
1. the staff passes through the oblique photography data of unmanned aerial vehicle collection building. The oblique photographing data mainly includes a triangulation network, a building picture, and the like.
2. The method comprises the following steps that a worker processes oblique photography data of a building, the processed data are loaded into relevant software, the worker disassembles the triangulation network in a manual or machine learning training mode, and a single model of the building is built one by one.
3. And smoothing the joints of the built monomeric models of the buildings, and exporting model files in corresponding formats for subsequent use.
Mode two, Identity Document (ID) monomerization:
1. the staff passes through the oblique photography data of unmanned aerial vehicle collection building.
2. The staff assigns the same ID to each vertex of the triangulation of the same building in the oblique shots.
As can be seen from the above, the first and second embodiments are mostly formed by manual work. Because there is a great risk of error in manual work and a great amount of time is required to process data, the error of the manual work mode is great and the efficiency of the singulation is low. Particularly, in the case where a large number of buildings need to be integrated, if a manual operation mode is adopted, a large amount of data processing work needs to be performed by a worker, and the workload is heavy.
In view of this, an embodiment of the present application provides a method for determining a singulation model, where the method includes: the determining device acquires oblique photography data and spatial geographic data of a target entity; the determining device determines a first vector plane of the target entity according to the oblique photography data and the space geographic data; the determining device superimposes the first vector surface on a three-dimensional model formed by oblique photography data of the target entity to obtain a single-body model of the target entity.
Based on the technical scheme provided by the embodiment of the application, the determining device acquires oblique photography data and space geographic data of the target entity, and determines the first vector plane of the target entity according to the oblique photography data and the space geographic data of the target entity. And finally, the determining device superimposes the first vector plane on the three-dimensional model formed by the inclined data to obtain the single model of the target entity. Since the oblique photography data and the spatial geographic data of the target entity can accurately reflect the structure of the target entity, the first vector plane of the target entity is consistent with the shape of the target entity. Based on the three-dimensional model of the target entity, the first vector plane is superposed on the three-dimensional model of the target entity, so that a single-body model of the target entity can be obtained. Under the condition that a large number of entities need to be individualized, the determining device can carry out the individuation of the entities in batches according to the technical scheme of the application, so that the manual operation is reduced, and the working efficiency is improved.

Fig. 2 provides a method for determining a singulation model according to an embodiment of the present application, and as shown in fig. 2, the method includes:
step 201, the determining device acquires oblique photography data and space geographic data of the target entity.
The determining device may be the communication device in fig. 1, or may include the components of the communication device in fig. 1, without limitation.
The description of the target entity and the oblique photography data can refer to the above description, and is not repeated.
Wherein the spatial geographic data of the target entity may be used to characterize the structure or shape of the target entity. The spatial geographic data of the target entity may include floor data of the target entity. The bottom surface data of the target entity means the bottom surface area of the target entity, the coordinate data of the bottom surface, and the like. Of course, other data may also be included, such as the maximum area occupied by space. The space footprint may refer to the area of the largest cross-section of the target entity. For example, taking the target entity as a building as an example, the floor data of the building may refer to the occupied area of the building and a plurality of vertex coordinates of the floor of the building. The space footprint of a building may refer to the cross-sectional area of the building.
In one possible implementation, the oblique photography data of the target entity may be acquired by a drone equipped with a camera. The spatial geographic data of the target entity may be acquired by a measuring instrument. Specifically, reference may be made to the prior art, which is not described in detail.
Further, the staff can input the oblique photography data and the space geographic data of the target entity acquired by the unmanned aerial vehicle and the measuring instrument into the determining device through the input device of the determining device. Of course, the determination device may also acquire the oblique photography data and the spatial geographic data of the target entity by interacting with the drone or the surveying instrument. For example, the determination device may be in data communication with the drone or the measurement instrument over a wireless network. The wireless network may be a fifth generation (5G) network, or may also be a network of other systems, without limitation.
Step 202, the determining device determines a first vector plane according to the oblique photography data and the space geographic data of the target entity.
Wherein the first vector plane may refer to a spatial triangulation network coinciding with an outer surface or part of an outer surface of the target entity. In the case where the determining means displays the target entity via the display, the first vector plane of the target entity may be a spatial triangulation network coinciding with the displayed portion of the target entity in the display. For example, as shown in fig. 3, the target entity portion that the user can visually see through the display is a polyhedron constituted by points a to H. The corresponding first vector plane of the building of fig. 3 may be the vector plane a ' B ' C ' E ' F ' G ' H ' as shown in fig. 4.
Wherein the first vector surface may include a plurality of coordinate data. The plurality of coordinate data may be coordinate data of a plurality of vertices of the target entity.
For example, as shown in fig. 3, taking the target entity as a building as an example, the spatial geographic data of the building may include bottom surface data of the building. For example, the coordinates of points B, C, E, and I in fig. 3 may be included. Of course, coordinates of other points, such as any one or more points on the line segment AB, may also be included. The building's oblique photography data may include texture data of the building in fig. 3 and coordinate data of a plurality of vertices. For example, the coordinate data of the plurality of vertices may include coordinate data of points a, B, C, D, E, F, G, H, and I. The first vector surface may be a surface formed by points a, B, C, D, E, F, G, and H. The first vector surface of the building may be an irregular curved surface.
In one possible implementation, the determining means determines height data of the target entity based on the floor data and the oblique photography data of the target entity; the determining device determines a first vector plane of the target entity according to the bottom surface data and the height data of the target entity.
The construction process of the first vector plane is described below with reference to the building of fig. 3:
1. the determining device determines height data of the target object based on the bottom surface data and the oblique photography data of the target object.
Wherein the height data of the target entity is a vertical distance from a target vertex to a bottom surface of the target entity in the oblique photography data of the target entity. The target vertex is a vertex having the largest distance to the bottom surface in the oblique photography data.
For example, the floor data of the building of fig. 3 includes coordinate data of four vertices (point B, point C, point E, point I) of the floor. The oblique imaging data includes coordinate data of a plurality of vertices (points a, B, C, D, E, F, G, H, and I).
In one possible implementation, the determining device may compare the floor data of the building with the oblique photography data to obtain the height data of the target entity.
For example, the determination means may determine the vertices in the oblique photography data corresponding to the plurality of points of the floor data by comparing the coordinate data of the plurality of points in the floor data of the building with the coordinate data of the plurality of points in the oblique photography data after acquiring the floor data of the building and the oblique photography data. The specifying device specifies the target vertex by using a plane including the plurality of vertices corresponding to the plurality of points of the bottom surface data as a reference plane. The target vertex is a vertex in the oblique photography data. The determining means may determine height data of the target entity from the target vertex. For example, the height data is the vertical distance of the target vertex from the reference plane. For example, when the reference surface is a bottom surface, the height data is a distance from the target vertex to the bottom surface.
Further, after determining the floor data and the height data of the target entity, the determining device may further store the floor data and the height data of the target entity. For example, the determining means may store the floor data as well as the altitude data of the target entity in a geographical information common format of GeoJSON or pbf or the like for subsequent use.
2. The determining device determines a first vector plane of the target entity according to the bottom surface data and the height data of the target entity.
In one possible implementation, the determining means may construct the vector plane using the bottom surface data and the height data of the target entity as a connection. For example, the determining means may sequentially connect a plurality of points in the bottom surface data and a corresponding point in the height data to obtain a surface that can cover the outer surface of the target entity. That is, the first vector plane of the target entity may be obtained.
Step 203, the determining device superimposes the first vector plane on the three-dimensional model formed by the oblique photography data of the target entity to obtain a single-body model of the target entity.
The three-dimensional model formed by the oblique photography data of the target entity may be a three-dimensional model obtained according to the oblique photography data of the target entity and three-dimensional model modeling software and used for representing the target entity.
For example, the three-dimensional model modeling software may be 3ds max, or the like. The determination means may be installed/provided with three-dimensional modeling software. The determining means may input oblique photography data of the target entity to the three-dimensional model modeling software to obtain the three-dimensional model of the target entity.
In one possible implementation, the determining device may determine, according to the coordinate data of the vertices of the three-dimensional model of the target entity and the coordinate data of the vertices of the first vector plane, a plurality of vertices of the three-dimensional model that are consistent with the coordinate data of the vertices of the first vector plane. For example, the coordinate data of the point a in fig. 3 coincides with the coordinate data of the point a ' in fig. 4, the coordinate data of the point B coincides with the coordinate data of the point B ' in fig. 4, and … …, the coordinate data of the point H coincides with the coordinate data of the point H ' in fig. 4. Based on this, the determining device may superimpose the plurality of vertexes of the first vector plane with the plurality of vertexes of which the coordinate data are consistent, respectively, and may superimpose the first vector plane on the three-dimensional model of the target entity to obtain the monolithic model of the target entity. For example, the determining means may superimpose the a 'point on the a point, superimpose the B' point on the B point, … …, superimpose the H 'point on the H point, that is, superimpose the vector plane a' B 'C' E 'F' G 'H' of fig. 4 on the building of fig. 3, and render it, so as to obtain the simplex model shown in fig. 5. For example, a target entity may be rendered by WebGL to obtain a monolithic model.
It should be noted that, in the embodiment of the present application, the first vector surface may be transparent or translucent.
Further, in order to improve the real effect of the individualized model of the target entity, the determining device may further construct a shadow volume for the individualized model of the target entity. Specifically, the method for constructing the shadow volume may refer to the prior art, and is not described in detail.
In addition, to facilitate viewing of the attribute information of the target entity, the determination device associates the individualized model of the target entity with the attribute information of the target entity. Therefore, the user can quickly and intuitively check the attribute information of the target entity through the single model of the target entity.
The attribute information of the target entity may include a name, a height, a construction age, and an attribute of the target entity. The attribute of the target entity may refer to a purpose of the target entity, for example, in case the target entity is a building, the attribute of the building may refer to a function of the building, such as a house, a shop, and the like.
Based on the technical scheme of fig. 2, the determining device obtains oblique photography data and spatial geographic data of the target entity, and determines the first vector plane of the target entity according to the oblique photography data and the spatial geographic data of the target entity. And finally, the determining device superimposes the first vector plane on the three-dimensional model formed by the inclined data to obtain the single model of the target entity. Since the oblique photography data and the spatial geographic data of the target entity can accurately reflect the structure of the target entity, the first vector plane of the target entity is consistent with the shape of the target entity. Based on the three-dimensional model of the target entity, the first vector plane is superposed on the three-dimensional model of the target entity, so that a single-body model of the target entity can be obtained. Under the condition that a large number of entities need to be individualized, the determining device can carry out the individuation of the entities in batches according to the technical scheme of the application, so that the manual operation is reduced, and the working efficiency is improved.
In order to implement visualization of a monolithic model of a target entity, as shown in fig. 6, a method provided in an embodiment of the present application may further include:
step 601, in response to a first operation instruction of the user on the individualized model of the target entity, the determining device may control the individualized model of the target entity to display a first brightness/color and/or output attribute information of the target entity.
The visualization of the individualized model of the target entity means that the individualized model of the target entity can be displayed through partial highlighting, layered coloring and the like. Partially highlighted means that the intensity of the individualized model of the target entity is higher than the intensity of the individualized models of the other entities. Hierarchical coloring may refer to the color of a target entity being inconsistent with the color of the individualized models of other entities.
Wherein the first operation instruction can be used for viewing the monomer model of the target entity. For example, taking the determining apparatus as a computer as an example, the first operation instruction may be an operation instruction generated by the determining apparatus when a user clicks the simplex model of the target entity using an input device such as a mouse or a keyboard. As another example, the first operation instruction may identify (e.g., name) the target entity entered by the user through a search window of a display of the determination apparatus. In response to a search instruction by a user, an operation instruction generated by the apparatus is determined.
Wherein the first brightness refers to a brightness of the simplex model of the target entity with a brightness higher than a threshold. That is, when the user views the target entity through the input device, the brightness of the target entity may be higher than that of the other entities, so that the user can quickly and accurately view the individualized model of the target entity.
Wherein, the first color refers to one or more colors displayed by the monomer model of the target entity. The first color may be preset by the determination device, and may be, for example, red or a mixed color of red and yellow, without limitation. Alternatively, different portions of the individualized model of the target entity may display different colors. For example, the roof of a building may display red and the walls of the building may display yellow.
The determining device may output the attribute information of the target entity, where the determining device may display the attribute information of the target entity through a display, and may display the attribute information of the target entity in a form of a table or a list, for example. For another example, the determination means may also output the attribute information of the target entity in the form of voice.
Example 1, as shown in fig. 7, when a user clicks the simplex model of the target entity of a in fig. 7 through a mouse, as shown in b in fig. 7, the simplex model of the target entity may display a first brightness or color, and/or display a first interface including attribute information of the target entity.
Example 2, as shown in fig. 8, when a user inputs an identification (e.g., name) of a target entity through a search window, as shown in b of fig. 8, a singulation model of the target entity may display a first brightness or color and/or display a first interface including attribute information of the target entity.
Example 3, as shown in fig. 9, taking the target entity as a street lamp as an example, in order to facilitate viewing of the coverage area of the street lamp, the individualized model of the street lamp may be a columnar model. In response to a click operation of the user on the individualized model of the street lamp, the determining device may control the individualized model of the street lamp to display the first brightness/color and/or output the attribute information of the street lamp.
Example 4 to allow batch viewing of entities having the same attribute information, a monolithic model of entities having one or more of the same attributes may also have an association. For example, for multiple entities located on the same display interface, the display interface has a search window. The user inputs 'building' through the search window, and the attribute information in the display interface displays a first brightness or color for the monomer model of all the entities of the building in response to the search instruction of the user.
Example 5, to allow batch viewing of attribute information for multiple entities. The determination means may further output attribute information of the plurality of entities in response to a query operation by the user. For example, the output may be in the form of a table. Further, the attribute information of the plurality of entities in the table may be partially identical. For example, when the user inputs "street lamps" through the search window, the determination device may input attribute information of a plurality of street lamps in response to a search instruction of the user.
Based on the possible implementation mode, through visualization of the single model of the target entity, the user can visually check the target entity and the attribute information of the target entity.
