Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the disclosed embodiments. However, it will be apparent to one skilled in the art that the present disclosure may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present disclosure with unnecessary detail.
The digital sand table is characterized in that a building model is displayed in front of a user in a three-dimensional visual mode through a three-dimensional model technology and a digital image technology, and compared with an entity sand table, the digital sand table is used for displaying relevant information of the building more intuitively and comprehensively through a virtual three-dimensional scene, and various three-dimensional visual special effects and sand table function applications can be supported. The digital sand table is also called a three-dimensional digital sand table, the three-dimensional digital sand table can display the model by displaying a digital image on a screen, and the model can be displayed on the screen by utilizing a three-dimensional GIS technology, a three-dimensional modeling technology and an internet technology.
In the application of the digital sand table technology, the house scene display is an important component function in the digital sand table, and the function supports users to select buildings and house types in the sand table model more intuitively through some simple interactions and screening, and simulates the landscape visual angles corresponding to the buildings, the floor heights and the house types, so that the use experience of house buyers is improved.
In the related art, the house scene configuration in the digital sand table is mainly generated based on a manual batch building mode, for example: the configurator manually configures the camera position of each house type in the digital sand table according to the house type distribution, the window position, the orientation and the like of the building, namely, the camera positions are added to each house type one by one in a manual mode, and parameters and labels such as the house type, the house number and the like are added. However, in the current actual scene, there may be tens of buildings and thousands of house types in one building, so that when there are many house types in the existing digital sand table by manual operation, the process of configuring the house view becomes more and more complicated, the consumed time and labor cost are higher and higher, the probability of human error is higher and higher, and meanwhile, the efficiency of configuring the house view in the digital sand table is greatly reduced.
In view of the above problems in the prior art, it is desirable to provide a room view display scheme that can automatically generate a corresponding camera point location for each room type in a digital sand table, improve the efficiency of room view configuration, reduce the difficulty of room view configuration, and improve the effect of room view display. The overall implementation process of the technical solution of the embodiment of the present disclosure is described below with reference to the accompanying drawings, and fig. 1 is a schematic overall processing flow diagram of the technical solution corresponding to the embodiment of the present disclosure. As shown in fig. 1, the overall process of the technical solution may specifically include:
on one hand, a complete building information model (such as a Revit model) corresponding to a building or a building is obtained, on the other hand, a model of a building specialty is screened from the building information model, and the building information model containing the building specialty is exported to be a model intermediate file, wherein the model intermediate file adopts a datasmith format; and on the other hand, analyzing the building information model obtained by screening, extracting house type information corresponding to each house type in the building information model, screening a window corresponding to each house type according to the building information model, further calculating a normal vector of each window, generating a camera point location based on the normal vector of the window, and exporting the house type information and the camera point location together into a Json format element information object.
Further, after exporting the model intermediate file in the datasmith format and the element information object in the Json format, the two parts of information are recorded by using a UE4 engine on which the digital sand table depends, wherein after the model intermediate file is loaded, the model intermediate file is directly rendered into a three-dimensional model in the digital sand table; after the element information object is loaded, the element information object is analyzed to generate a house type block of each house type, a camera object is added at a position corresponding to the coordinates of the camera point in the house type block according to the camera point in the element information object, and an interaction mode between the camera object and the house type block is established, for example: and configuring the click house type block to move the view angle of the sand table model to the view angle corresponding to the camera object. The configuration operation of the whole house scene is completed, and when an interaction request aiming at a certain house type in the digital sand table is received, the visual angle of the digital sand table is adjusted to the visual angle of the camera object corresponding to the house type, so that the effect that one house type corresponds to one external scene, namely the effect of displaying one house scene is achieved.
Fig. 2 is a schematic flow chart of a house view display method based on a digital sand table according to an embodiment of the present disclosure. The digital sand table-based house view display method in fig. 2 may be executed by a server, and as shown in fig. 2, the digital sand table-based house view display method may specifically include:
s201, acquiring a first building information model, processing a model file corresponding to the first building information model to obtain a second building information model, and converting the second building information model into a model intermediate file with a preset format;
s202, sequentially traversing each house type in the second building information model to obtain house type data corresponding to each house type, generating a camera point location corresponding to each house type based on window attribute information, and combining the house type data and the camera point location into an element information object;
s203, loading the model intermediate file by using an engine corresponding to a preset digital sand table so as to render a building model corresponding to the model intermediate file in the digital sand table, and performing analysis operation on the element information object to obtain a house type block corresponding to each house type;
and S204, establishing an interactive relation between the camera point location of each house type and the house type block, and adjusting the visual angle of the digital sand table to the visual angle of the camera point location when the selection operation of the house type block in the building model for the digital sand table is triggered so as to display the house scene corresponding to the visual angle of the camera point location.
Specifically, the digital sand table in the embodiment of the present disclosure may be considered as a three-dimensional digital sand table constructed by a three-dimensional building model and an external scene in a certain range around the building, where the number of the three-dimensional building model is not limited, and the three-dimensional building model may be a single building or a building composed of multiple buildings; the exterior scene of the building is a virtual exterior scene environment which is constructed in advance according to the actual exterior scene within several kilometers of the periphery of the building, and the exterior scene of the building comprises but is not limited to the following scenes: trees, other buildings, lakes, rivers, etc.
Further, the first building Information model and the second building Information model may both adopt a model based on BIM forward design, BIM (building Information modeling) is referred to as a building Information model for short, BIM refers to a process of creating and managing building Information in a whole life cycle of planning, designing, constructing, operating and maintaining stages of construction engineering and facilities, and a three-dimensional, real-time and dynamic model applied in the whole process covers geometric Information, spatial Information, geographic Information, property Information of various building components and work and material Information. In BIM, Revit is a mainstream BIM visualization and modeling tool, and therefore, the building information model in the embodiment of the present disclosure may adopt a Revit model.
Further, the model intermediate file in the predetermined format refers to a model file that can be recognized and loaded by the UE4 engine, and in practical applications, the model intermediate file may be a model file of the datasmith suffix. Here, the UE4 engine is a game engine, and the underlying engine of the digital sand table in the embodiment of the present disclosure uses the UE4 engine, but of course, other 3D engines can be used as the underlying engine of the digital sand table as well, besides the UE4 engine. The house scene in the embodiment of the present disclosure is shown in the digital sand table of the UE4 engine, and the interactive function of the house scene is also implemented in the digital sand table of the UE4 engine.
According to the technical scheme provided by the embodiment of the disclosure, the embodiment of the disclosure comprises two parts, namely, a first part, converting a Revit model into a model file in a datasmith format, analyzing the Revit model to obtain attribute data (namely house type data) of each house type, calculating a camera point location corresponding to each house type, and generating an element information object in a Json format according to the attribute data of the house type and the camera point location; and a second part, loading a model file in a datasmith format on a digital sand table based on a UE4 engine, analyzing element information objects in a Json format, generating a house type block of each house type, and establishing an interactive relation between a camera point position and the house type block, so that the house type blocks have a certain interactive function, and when the house type blocks are clicked, the view angle of the whole digital sand table can be moved to the view angle of the camera point position corresponding to the house type blocks. The method and the device can automatically generate corresponding camera point positions for each house type, reduce the problems of low configuration efficiency and increased error rate caused by manual configuration, reduce the difficulty of house scene configuration and improve the house scene display effect.
In some embodiments, obtaining a first building information model, and processing a model file corresponding to the first building information model to obtain a second building information model includes: acquiring a model file and a file name corresponding to the model file, sequentially matching the file names of the model files according to a key character string corresponding to a preset target model file, and loading the successfully matched model file to obtain a second building information model; the target model file is a model file related to the building structure, and the first building information model and the second building information model are both Revit models.
Specifically, the first building information model may be considered as an initial model including multiple specialties, in practical applications, a complete Revit model may include multiple specialties, such as a building model, an electromechanical module, a structural model, and the like, and generally only a building specialties model is needed in the digital sand table, so that the model in the initial building information model (i.e., the first building information model) is first screened, and only the building specialties model needs to be loaded.
It should be noted that models of different specialties in the building information model can be regarded as models under different layers, that is, one speciality corresponds to one layer file, and for a complete Revit model, all speciality models are displayed. The following describes a process of loading a second building information model with reference to a specific embodiment, which may specifically include the following:
generally, after building information models are obtained by utilizing BIM forward design, different types of model structures have independent and regularized naming modes, for example, file names of a building professional model and an electromechanical professional model are different, so that the different types of models can be distinguished through the names of model files, and then which model files are target model files needing to be loaded finally are judged. For example, the naming rule of the architecture professional model is "XX-project name-a-f 01. rvt", when the Revit model file is loaded, all file names in the Revit model file can be traversed by using key character strings through a native API interface in the Revit model, wherein the key character strings are character strings generated based on the naming rule of the architecture model, and the "-a-" key character strings can be generated according to the naming rule to traverse and match the model file, so that the model file conforming to the naming rule is screened out, and the matched model file is loaded, and the unmatched model file is not loaded.
In some embodiments, converting the second building information model into a model intermediate file of a predetermined format includes: and converting the Revit model corresponding to the second building information model into a model intermediate file in a format with datasmith as a suffix.
Specifically, the second building information model may be considered to only include a building model, the datasmith format is an intermediate format that the Revit model supports loading to the UE4 engine, a special plug-in and API export interface are provided in the UE4 engine, and the model intermediate file that exports the Revit model file into the datasmith format is a function possessed by the Revit model, and therefore, the specific process of format conversion is not described in the embodiment of the present disclosure.
In some embodiments, sequentially traversing each house type in the second building information model to obtain house type data corresponding to each house type includes: determining all floors in the second building information model, and traversing the house type in each floor in sequence along the floors by taking the floors as units so as to extract a floor identifier, a house type identifier, an outer contour line and an elevation corresponding to each house type; the method comprises the steps of calculating the house type area corresponding to each house type according to the area parameter corresponding to each room in each house type, generating structured data based on floor identification, house type identification, outer contour lines, elevation and the house type area, and taking the structured data as house type data.
Specifically, in the Reivt modeling process, a designer can firstly build a model of a standard floor of a building, or build a half of the standard floor, then obtain a complete standard floor along the center line in bilateral symmetry, completely build the middle floor of the building in a mirror image or copy mode, and finally complement the bottom floor and the top floor of each building. In the process of modeling the standard layer, a designer can finish building the wall facades of all rooms on the same layer, and labels, area outlines and the types of the rooms are marked. Therefore, when the second building information model is traversed to generate the house type data, the standard layer may be used as a basic traversal unit to traverse attribute data of all rooms, and the following detailed description is given to the traversal process of the house type data in combination with a specific embodiment, and may specifically include the following contents:
the data files corresponding to each floor in the second Reivt model file (namely, the second building information model) are obtained, the data files corresponding to each room in each floor data file are sequentially traversed, each room is classified according to the house type, an array structure of one house type dimension can be obtained through traversing data, and the array structure of each house type dimension comprises an array structure of one or more room dimensions. The array structure of each house type dimension at least comprises information such as a floor mark, a house type mark, an outer contour line, an elevation and the like, area parameters corresponding to rooms forming each house type are added, and then the whole area of each house type is obtained.
Further, according to the calculated whole area of each house type, the floor identification, the house type identification, the outer contour line and the elevation of each house type obtained through traversal are combined, a set of data structure used for describing the house type structure is generated comprehensively through the parameters, and the structured data are used as house type data. It should be noted that the above-mentioned so-called standard floor can be regarded as an intermediate floor after the top floor and the bottom floor of the whole building are removed, that is, in practical application, the floor data file representing the intermediate floor in the Reivt model file can be regarded as a file of the standard floor, and of course, in the embodiment of the present disclosure, the standard floor can be regarded as any floor in the intermediate floor.
In some embodiments, generating a camera site location corresponding to the house type based on the window attribute information comprises: acquiring window attribute information corresponding to each house type, determining a wall facade corresponding to a window according to the window attribute information, calculating a plane vector of a center line corresponding to the wall facade, and determining a normal vector of the window according to the plane vector; and respectively moving the window along the normal vector of the window to positive and negative directions for a preset distance to obtain two point location coordinates, judging whether the point location is in the outer contour line according to the point location coordinates, and taking the point location coordinates belonging to the outer contour line as the camera point location.
Specifically, before obtaining the window attribute information corresponding to each house type in the second Reivt model file, it is first necessary to determine which windows in the house type correspond to which window attribute information is processed to generate a camera point location. Since one house type may correspond to a plurality of windows, when the UE4 engine shows the external landscape of the house type, it is often only necessary to pay attention to the landscape at the positions of the balcony and the main-lying window, and therefore, when acquiring the window attribute information in the Reivt model file, only the window attribute information corresponding to the balcony and the main-lying window may be acquired. The following describes how to select a specific window attribute information extraction process in the Reivt model file with reference to a specific embodiment, which may specifically include the following:
in the Revit model file, windows are represented by points, a room-shaped contour line is a closed surface, the intersection relation between the points and the surface is used for judging which points (windows) are in which contour lines (rooms), and the windows belonging to balconies and living rooms can be obtained according to room label information mapped on contour lines. The point location of the window is intersected with the outer contour line according to the outer contour line and the point location corresponding to the window in the second building information model, and the room where the window is located is judged according to the intersection relationship between the point location of the window and the outer contour line.
Further, after determining window attribute information corresponding to a window to be extracted, a camera point location is generated according to the window attribute information, and a detailed description is given below of a generation manner of the camera point location with reference to the accompanying drawings and specific embodiments. Fig. 3 is a schematic diagram of determining a camera point location in a Revit model according to an embodiment of the present disclosure. As shown in fig. 3, the generation process of the camera point location may specifically include:
the center point position of a balcony window or a main horizontal window is obtained, the normal direction of the window is calculated, and in Revit modeling design, the window is usually hung on a wall surface, so that the wall vertical surface corresponding to the window can be found out through window attributes, the XY plane vector of the center line corresponding to the vertical surface is calculated, the normal vector perpendicular to the wall vertical surface is further calculated, and the normal vector of the window is a three-dimensional vector perpendicular to the wall vertical surface. The method for calculating the camera location is shown in fig. 3, and the center point of a window is taken as a circular point, the window is moved by 1m in the positive direction and the negative direction of a normal vector to obtain two locations, whether the locations are included in the contour line of a room is judged according to the locations, if the locations are included, the locations are taken as correct camera locations, and the coordinates of the camera locations are stored.
In some embodiments, combining the house type data and the camera point locations into a factor information object comprises: and generating a data structure for representing the house type structure and the camera position for each house type according to the house type data corresponding to each house type and the camera position, and exporting the data structure into an element information object in a Json format.
Specifically, after house type data is analyzed from the Revit model file and camera point locations are determined through calculation, a key element information object in a Json format is generated for each house type according to the house type data and the camera point locations, and the key element information object comprises information such as a floor identifier, a house type identifier, an outer contour line, an elevation, an overall area, a window positive direction, a window center point location and the camera point location corresponding to each house type. Therefore, the element information object in the finally generated Json format includes coordinates corresponding to the camera point location.
It should be noted that each model intermediate file corresponds to a model file identifier, and a corresponding relationship between the model file identifier and the identifier of the element information object is established. In practical application, information such as house type outer contour lines, house type identifiers (such as house numbers), room contours (two-dimensional arrays corresponding to contour line coordinates), elevations and the like can be further extracted, and unique room identification IDs are generated and associated.
According to the technical scheme provided by the embodiment of the disclosure, the Revit model is converted into the model intermediate file in the datasmith format, house type data is obtained through extraction and analysis according to the Revit model file, corresponding camera point positions are generated based on the house type data, and the house type data and the camera point positions are combined into element information in the Json format, so that the electronic sand table based on the UE4 engine can automatically load the model intermediate file and analyze the element information. The corresponding camera point location is automatically generated for the window of each house type, the camera point location does not need to be manually added, the workload of house scene configuration is reduced, and the accuracy of the camera point location during house scene configuration is improved.
In some embodiments, the engine corresponding to the preset digital sand table employs a UE4 engine, and loads the model intermediate file by using the engine corresponding to the preset digital sand table, so as to render the building model corresponding to the model intermediate file in the digital sand table, including: and loading the model intermediate file in the datasmith format into a UE4 engine by using a preset plug-in, rendering the building model corresponding to the model intermediate file in the UE4 engine, wherein the rendering is used for displaying the effect corresponding to the building model in a pre-configured digital sand table containing the external scene of the building.
Specifically, the UE4 engine provides a datasmith plug-in for importing and loading the datasmith data converted by the Revit model into the UE4 engine, that is, the model intermediate file in the datasmith format is automatically loaded into the UE4 engine by calling the datasmith plug-in through an API preset in the UE4 engine.
Here, the datasmith format is a model file used for expressing a model interface and a presentation effect in a digital sand table, the datasmith model file does not have interaction and parameter association functions, the Json element information file loaded and parsed in the UE4 engine is used for generating some block models (house-type blocks) for interaction, and a user clicks not the datasmith model when actually doing interaction but a block generated based on the Json file and specially used for interaction.
In some embodiments, performing a parsing operation on the element information object to obtain a house type block corresponding to each house type includes: and serializing the element information objects in the Json format, traversing house type data corresponding to the house types in the serialized element information objects, and constructing house type blocks corresponding to the house types in a three-dimensional coordinate system of the UE4 engine according to outer contour lines and elevations corresponding to the house types.
Specifically, the serialization process of the element information object may be regarded as a process of converting the object into a data format (e.g., into a byte string of a specific format) that can be transmitted through a network or stored to a local disk. And traversing the element information after the serialization processing, traversing all floors and house types, generating a house type block according to an outer contour line and an elevation of the house type, and associating the house type identifier with the house type block. The following detailed description of the generation process of the atrial block with reference to the specific embodiment may specifically include the following:
the three-dimensional space in the UE4 engine is a three-axis coordinate system, which is the X-axis, Y-axis, and Z-axis, respectively.
