Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a flow chart of steps of a method for constructing a three-dimensional room space according to an embodiment of the present invention is shown.

Step 110, acquiring initial data of a target house, wherein the initial data comprises at least one of 3D (three-dimensional) house type data and 2D house type data;

step 120, acquiring a three-dimensional space of each functional area in the target house according to the initial data, wherein the functional area model data is data for constructing a 3D functional area model of the at least one functional area;

step 130, combining the three-dimensional spaces of the specific function areas in the target house into a three-dimensional space, and combining the three-dimensional space of a non-specific function area to obtain the three-dimensional house space of the target house, so as to render a house decoration result in the three-dimensional house space according to decoration data of each function area, wherein the non-specific function area is other function areas except the specific function area.

In order to simulate decoration effects of different houses, modeling can be performed on the houses in VR decoration, three-dimensional models of the houses are built in 3D modeling software, materials and maps are given to wall surfaces, floors, ceilings and skirting lines in the houses based on the three-dimensional models of the houses, various furniture is arranged in the houses according to different functional areas, various lights are arranged in the houses according to the decoration effects, and finally the decoration effects are rendered to be virtual decoration effects.

Before simulating the decoration effect of the target house, the above process firstly needs to construct a complete 3D (3 Dimensions) house space of the target house for rendering the decoration effect in scenes such as VR decoration. Moreover, in practical applications, the initial data for building a 3D room space available for different rooms may be different in different application scenarios. For example, in an application scenario such as VR house watching, 3D house type data of each functional area included in a house may be provided; for a newly built house or a house under construction, only 2D (2 Dimensions, two-dimensional) user type data (e.g., a 2D user type graph or a hand-drawn user type graph, etc.) of the corresponding house may be provided; and so on.

The 3D house type data may include any 3D data related to the house type of the target house, for example, in a VR house viewing scene, the 3D house type data may be data for representing the house type structure except for map data of each functional area in VR panoramic data of the target house, that is, the 3D house type data may be combined with the map data of each functional area, and is used to show VR effects of each functional area in the house in electronic devices such as a PC (personal computer) end, an APP (Application) end, and a VR device end, and the 3D house type data may include information of each functional area in the house, such as information of a wall surface, a door, a window, an observation point in the functional area, an entrance door, an area of the functional area, a house orientation, and the like. In the embodiment of the present invention, the 3D house type data may be acquired by any available method, which is not limited to this embodiment of the present invention. For example, 3D house type data of a target house may be acquired from an application scene such as VR house watching, and so on.

Therefore, in the embodiment of the present invention, in order to obtain modeling data of a 3D house space of a target house, initial data of the target house may be obtained, where the initial data includes at least one of 3D house type data and 2D house type data of the target house; and then, the three-dimensional space of each functional area in the target house can be obtained according to the initial data of the target house.

For example, for 3D house type data, the data required for constructing the three-dimensional space of each functional area may be included, and in addition, other data only applicable to VR scenes, such as an indoor map, a cover picture, a nomadic scale, default roaming point data, and the like, then the data required for constructing the three-dimensional space may be extracted from the data, and the extracted data is processed to generate the three-dimensional space of each functional area in the target house; for 2D house type data, because only plane information of a target house is contained, available plane information contained in the 2D house type data can be extracted and processed into three-dimensional space data, and therefore a three-dimensional space of each functional area in the target house type data is generated; and so on.

In addition, in practical application, a house may be a combination of a plurality of functional areas, and the division manner of the functional areas included in the target house may also be set by self-definition according to requirements, for example, the functional areas may be divided according to the functions of each area in the target house, so that the divided functional areas may include bedrooms, living rooms, restaurants, toilets, hallways, galleries, kitchens, balconies, and the like; alternatively, the functional area included in the target house may be divided according to a rectangular area included in the recognition target house, or the like.

Moreover, in practical applications, the space plan of different houses may be different, and the connection manner between different spaces or functional areas may also be different, for example, there is a wall between some spaces (bedroom and living room) and the connection is performed through a door, and there is an open wall (i.e., there is no solid wall and the connection is performed through an open space) between some spaces (living room and dining room). For two spaces which are separated by a wall and connected by a door at the same time, the two spaces can be identified as two functional areas through the wall, and for two spaces between which no wall exists, the functional areas contained in the two spaces can be identified in any available mode such as rectangular areas, and the like, and the embodiment of the invention is not limited.

For example, in the case of a living room space and a restaurant space connected by an open space, they may be divided into two functional areas, i.e., a living room and a restaurant, by identifying a rectangular area, or they may be directly identified as a whole as a living room functional area, or the like.

In addition, after the three-dimensional space of each functional area is obtained, the decoration data of each functional area may be set according to the three-dimensional space of each functional area, where the decoration data may include at least one of hard-pack data and soft-pack data.

Specifically, the decoration data of each functional area may be obtained according to the spatial attribute of the three-dimensional space of each functional area, so as to display a decoration model object corresponding to the decoration data in the three-dimensional space of the functional area, and obtain an on-line decoration result of the target house; the content specifically included in the spatial attribute may be set by user according to a requirement, and the embodiment of the present invention is not limited thereto.

For example, in practical applications, the decoration modes generally applied to the spatial objects of different spatial types may differ, so that the spatial attributes of the spatial object may include at least a spatial type of the functional area, the decoration data may include at least one of hard-pack data and soft-pack data, the soft-pack data may include furniture layout data, and the furniture layout data may include at least one furniture model object and position information of the furniture model object.

The hard-fit data may include any data related to the hard-fit of the house, such as wall-fitting data, door-window fitting data, floor fitting data, ceiling fitting data, and the like. The soft-fit data may then include any data related to the house soft-fit, such as furniture layout data. The furniture layout data may include layout data related to movable interior decoration such as furniture, home appliances, curtain cloth, green plants, and the like. Furthermore, at least one furniture model object and position information corresponding to each furniture model object can be included in the furniture layout data. The furniture model object may be any of the above-described interior decoration model objects.

Furthermore, in order to identify different functional areas contained in the house in the 2D house type data, the identified different functional areas are generally marked as different closed areas, as shown in fig. 3A. Accordingly, for the 3D house type data, in order to facilitate the display of each area in the house, each functional area may be considered as a closed area in the 3D house type data, so that the roaming may be performed in each functional area in an application scene such as VR watching a house, and therefore, the above problem may also occur, thereby causing the three-dimensional spaces to be between each other when the three-dimensional space of each functional space is constructed. However, when a three-dimensional house space is constructed, in order to improve the accuracy of the three-dimensional house space obtained by construction, it is necessary to merge three-dimensional spaces of functional areas (e.g., a living room, a restaurant, an entrance, an aisle, etc.) connected therein into one three-dimensional space, and ensure that no wall or the like exists at the connection part of the three-dimensional spaces of the functional areas included in the merged three-dimensional space, so that the relative spatial relationship between the three-dimensional spaces of the functional areas in the three-dimensional house space of the target house obtained by final construction can correspond to the relative spatial relationship of the corresponding functional areas under the target house one by one.

Therefore, in the embodiment of the present invention, in order to improve the accuracy of modeling data, the three-dimensional spaces of specific functional areas in the target house may be merged into one three-dimensional space, and the three-dimensional space of a non-specific functional area, which is a functional area other than the specific functional area, is combined to obtain the three-dimensional house space of the target house, so as to render a house decoration result in the three-dimensional house space according to the decoration data of each functional area.

The specific functional area may be set by user according to a requirement or an actual situation of the target house, which is not limited in this embodiment of the present invention. For example, the specific function regions may include the living room, the dining room, the hallway, the aisle, and the like, and after the merged three-dimensional space is obtained, the three-dimensional room space of the target room may be constructed and obtained based on the merged three-dimensional space and the three-dimensional spaces of other non-specific function region regions, and specifically, the three-dimensional spaces of the function regions may be combined according to the relative spatial relationship of the function regions in the target room, so as to obtain the three-dimensional room space of the target room.

And after the three-dimensional house space of the target house is constructed, the house decoration result can be rendered in the three-dimensional house space according to the decoration data of each functional area in the subsequent VR decoration process, so that the decoration data under different decoration styles can be modeled in the three-dimensional house space, and the decoration effect under different decoration styles can be conveniently previewed by a user or displayed by a merchant.

Referring to fig. 2, in an embodiment, the step 120 may further include:

step A121, in a case that the initial data includes 3D house type data, analyzing the 3D house type data of the functional area for each functional area in the target house, and extracting first target data of the functional area from the analyzed 3D house type data;

step A122, constructing a three-dimensional space of the functional region according to the first target data; the first target data at least comprises wall data, door data, window data and observation point data.

In the embodiment of the present invention, the 3D house type data may be parsed and the first target data therein may be extracted in any available manner, which is not limited in the embodiment of the present invention.

For example, the 3D house type data of each functional area in the corresponding target house may be traversed, and the first target data, such as wall data, door data, window data, viewpoint data, etc., of each functional area may be extracted and processed.

The 3D house type data of each functional area is assumed to be a data packet named from, and different processing functions may be defined for different data dimensions to extract first target data under different data dimensions, so that the data packet of each functional area may be processed by calling different processing functions to obtain first target data corresponding to the corresponding functional area, and the obtained first target data of each functional area may be stored in a designated data packet, so as to be called when a three-dimensional space and a three-dimensional house space are subsequently constructed.

For example, functions for acquiring wall (walls) data, door (doors) data, window (windows) data, and viewpoint (hotspots) data may be set and defined as get _ wall _ from _ vr (), get _ door _ from _ vr (), get _ window _ from _ vr (), and get _ hotspots _ from _ vr (), respectively. Then, in order to obtain the wall data of any functional area at this time, the 3D house type data of the corresponding functional area can be parsed by get _ wall _ from _ vr (room) and the wall data can be read from it, and so on.

Further, a three-dimensional space of the functional region may be constructed based on the first target data. Optionally, in an embodiment, a data packet of each functional area in a target house may be generated based on first target data of the functional area, and when the data packet of the functional area is generated, a data format of data in the same data dimension when a three-dimensional space is constructed may be different from a data format of the data in 3D house type data, so that when the data packet of each functional area is generated, format adjustment may also be performed on the first target data therein to make the first target data meet the data format when the three-dimensional space is constructed, and different data dimensions (for example, a wall data dimension, a door data dimension, a window data dimension, an observation point data dimension, and the like) corresponding to the data format when the three-dimensional space is constructed may be set in a customized manner according to requirements, which is not limited in this embodiment of the present invention; moreover, in order to facilitate the subsequent generation of the three-dimensional house model of the target house at any time, the data packet of the target house can be constructed based on the data packet of each functional area. For example, for any functional area, the extracted first target data in each data dimension may be recorded into a corresponding designated data packet (e.g., a percentage _ room data packet) of the corresponding functional area, and then the designated data packet of each functional area may be recorded into a designated data packet (e.g., a percentage _ data packet) for storing the target house, so as to obtain a three-dimensional house model of the target house through rendering at any time based on the designated data packet corresponding to the target house.

For example, for the data dimension described above, in order to construct the decode _ data [ ], the first target data of any one functional region may be processed separately in the following manner to generate a decode _ room data packet based on each first target data.

decorate_room＝{}

decorate_room['walls']＝walls

decorate_room['doors']＝doors

decorate_room['windows']＝windows

decorate_room['hotspots']＝hotspots

decorate_room['area']＝area

Furthermore, the decode _ data packet of the target house can be generated through the following function, that is, the decode _ room data packet is stored in the decode _ data packet:

decorate_data.append(decorate_room)

here, the decode _ data _ allowed function may be understood as a function for storing a decode _ room packet into a decode _ data packet.

It should be noted that the wall data may include any data related to the wall, such as coordinates of the inner and outer walls of each wall, the size of the wall, the position of the wall, the functional area to which the wall belongs, and the like; door data may also include any data related to the doors, such as the coordinates, size, location, orientation, functional area, etc. of each door; the window data may also include any data related to the windows, such as coordinates, dimensions, position, orientation, functional area, etc. of each window; the viewpoint data may also include any data relating to the viewpoint, such as position coordinates of the viewpoint, height data from the ground, and the like; and so on. Where the observation point may also be referred to as a roaming point, a camera point location, etc.

In addition, in practical application, heights of different functional areas in the same house may be different or have a deviation in the 3D house type data, so that when the first target data of different functional areas are obtained, heights of walls in the first target data are different, so that the heights of three-dimensional spaces of different functional areas in the same house are different, and accuracy or attractiveness of a three-dimensional house space obtained by subsequent construction is easily affected. Therefore, when the first target data is extracted based on the 3D house type data, any data having special requirements, such as the wall height data obtained by initial extraction, may be subjected to corresponding special processing, for example, a specified height (e.g., 2.8m) is uniformly set for the wall height data obtained by initial extraction, and the wall height data obtained after resetting is used as the wall data in the first target data, and so on.

Referring to fig. 2, in an embodiment, the step 120 may further include:

step B121, under the condition that the initial data includes 2D house type data, analyzing the 2D house type data of the functional area for each functional area in the target house, and extracting second target data of the functional area from the analyzed 2D house type data, wherein the second target data at least includes 2D wall data, 2D door data and 2D window data;

step B122, generating first target data of the functional area according to second target data of the functional area, wherein the first target data at least comprises wall data, door data, window data and observation point data;

and step B123, constructing a three-dimensional space of the functional area according to the first target data.

And in case that the initial data includes 2D house type data, the 2D house type data of the functional area may be analyzed for each functional area in the target house, and second target data of the functional area may be extracted from the analyzed 2D house type data.

The 2D house type data may be parsed and the second target data may be extracted in any available manner, which is not limited in the embodiments of the present invention. For example, according to the 2D house type data, the wall segment line in the 2D house type data may be recognized as 2D wall data, the door and window picture may be recognized as 2D door data and 2D window data, and other necessary second target data such as an entrance door and an orientation may be recognized from the 2D house type picture by any available algorithm such as ai (Artificial Intelligence) Recognition algorithm, OCR (Optical Character Recognition) algorithm, etc.

However, in the 2D house type data, the wall surface is a line segment, the position information of the door and the window is generally represented by two points, and the data of the entrance door is also represented by two points, so that the data needs to be converted into stereo data to accurately and completely construct the three-dimensional house space. Furthermore, since the viewpoint data generally exists in the three-dimensional data, the viewpoint data cannot be directly extracted from the 2D house type data.

Therefore, in the embodiment of the present invention, in order to construct a three-dimensional space of a functional region, first target data of the functional region may be generated according to second target data of the functional region, where the first target data may include at least wall data, door data, window data, and viewpoint data, so as to convert the two-dimensional second target data into the three-dimensional first target data. Furthermore, in the embodiment of the present invention, the second target data in two dimensions may be converted into the first target data in three dimensions in any available manner, which is not limited in the embodiment of the present invention. Further, a three-dimensional space of the functional region may be constructed based on the first target data.

Optionally, for 2D house type data, in an embodiment, for each functional area in the target house, a data packet of the functional area may be generated based on the first target data of the functional area, so as to generate a three-dimensional space of the functional area; furthermore, the data packet of the target house may be constructed based on the data packet of each functional area so as to generate a three-dimensional house space of the target house.

For example, the 2D house type data of each functional area in the corresponding target house may be traversed, and the first target data such as wall data, door data, window data, viewpoint data, etc. of each functional area may be processed.

The 2D house type data of a certain functional area is assumed to be a data packet named from in a 2ddat data packet, and different processing functions may be defined according to different data dimensions in the process of analyzing the 2D house type data and extracting second target data, so that the data packet of each functional area may be processed by calling different processing functions to obtain second target data corresponding to the corresponding functional area, and different processing functions may be called to obtain first target data, and the obtained first target data of each functional area may be stored in a specified data packet, so as to be called when a three-dimensional space or a three-dimensional house space is subsequently constructed.

For example, a processing function of extracting 2D wall data and converting it into wall (walls) data, a processing function of extracting 2D door data and converting it into door (doors) data, a processing function of extracting 2D window data and converting it into window (windows) data may be set and defined as get _ wall _ from _2D () get _ door _ from _2D (), get _ window _ from _2D (), a processing function of extracting an internal window, a processing function of acquiring viewpoint data (hotspots), a processing function of acquiring functional area data (area) may be set and defined as calsulte _ inner _ window (), calsullate _ hotspot (), calsullate _ area (), and calsullate _ area (), respectively. Then, in order to obtain the viewpoint data of any one functional region at this time, the viewpoint data of the corresponding functional region may be obtained by hotspot ═ computing _ hotspot (room), and so on.

Further, a three-dimensional space of the functional region may be constructed based on the first target data. Specifically, for each functional area in the target house, a three-dimensional space of the functional area may be generated based on the first target data of the functional area. The specific process may refer to the specific process of constructing the three-dimensional space of the functional region according to the first target data under the condition of the 3D house type data, which is not described herein again.

For example, for each data dimension under the first target data, the third target data of any functional area may be processed in the following manner to generate functional area model data of the functional area.

Optionally, in an embodiment, the step B122 may further include:

step B1221, generating wall data of the functional area according to the 2D wall data of the functional area and a preset wall height;

step B1222, generating door data and window data of the functional area according to the 2D door data and 2D window data of the functional area and a preset door and window height;

and step B1223, generating the observation point data of the functional area according to the second target data of the functional area.

As described above, in the 2D house type data, the wall surface is a line segment, the position information of the door and the window is generally represented by two points, and the data of the entrance door is also represented by two points, so that it is necessary to convert the data into the stereoscopic data. Optionally, in order to convert the second target data in the two-dimensional plane into the first target data in the three-dimensional space, data such as a door, a window, a wall and the like are mainly converted into stereo data, and viewpoint data is obtained.

Specifically, in order to quickly complete the conversion of the second target data, data such as a wall height, a door and window height and the like may be preset, so that the wall data of the functional area may be generated according to the 2D wall data of the functional area and the preset wall height; generating door data and window data of the functional area according to the 2D door data and the 2D window data of the functional area and a preset door and window height; and generating viewpoint data of the functional region based on the second target data of the functional region.

The wall height, the door and window height and the like can be set in a user-defined mode according to requirements and specific application scenes, and the embodiment of the invention is not limited.

For example, wall heights of 2.8m (meters), 2.5 meters, etc. may be set, door heights of 2.2m, 2.5m, etc. may be set, window heights of 900mm (millimeters) from the bottom of the window to the floor of the house, 300mm from the top of the window to the top of the house, etc. may be set.

In addition, in practical applications, the types of windows in the house can be divided into a plurality of types, such as a French window, a bay window, a normal window, and the like, and then the heights of the windows of different types can be set respectively.

For example, the window height for setting a bay window includes the bottom of the window being 400mm (millimeters) from the floor of the house, the top of the window being 300mm from the top of the house, the window height for a french window includes the bottom of the window being 300mm or 100mm from the floor of the house, the top of the window being 300mm from the top of the house, and so on.

In addition, when the observation point data is obtained, the relationship between the observation point data and the second target data may be set by user according to requirements, and the embodiment of the present invention is not limited. For example, for any functional area, coordinate information of a position at a specified height from the floor height of the house in the center line of the minimum rectangle that may include the plane area in the corresponding functional area may be acquired as viewpoint data of the functional area, and so on, based on the second target data of the functional area.

Optionally, in an embodiment, the step B1223 further includes:

step S1, acquiring the plane shape type of the functional area according to the second target data of the functional area;

step S2, in response to the plane shape type of the functional region being a rectangle, taking the position data of the center point of the largest rectangle within the functional region as the viewpoint data of the functional region.

Step S3, in response to the planar shape type of the functional region being an L shape, taking position data of a center point of an intersection region of two rectangles within the functional region as viewpoint data of the functional region.

Step S4, in response to the planar shape type of the functional region being a U shape, taking position data of center points of three rectangles in the functional region as viewpoint data of the functional region, respectively.

Step S5, in response to the functional region containing more than three rectangles, using the position data of the center point of each rectangle as the observation point data of the functional region.

In practical applications, a plurality of observation points may be included in one functional area, and in order to ensure that each corner in the three-dimensional space of each functional area can be previewed in the process of subsequently constructing and navigating the three-dimensional room space, it is required to ensure that the observation points are located so as to facilitate previewing the whole content of the three-dimensional room space.

Specifically, the plane shape type of the functional region may be acquired from second target data of the functional region. For example, the plane shape type of the functional area may be obtained from wall data such as the number of walls, the length of each wall, the connection relationship between the walls, and the positions of the walls included in the second target data. If the planar shape type of the functional area is a rectangle, the position data of the center point of the largest rectangle in the functional area can be used as the observation point data of the functional area, as shown in fig. 4(a), where the position of the ring can be an observation point; if the planar shape type of the functional region is an L shape, the position data of the center point of the intersection region of two rectangles in the functional region may be used as the viewpoint data of the functional region, as shown in fig. 4 (b); if the planar shape type of the functional region is a U shape, the position data of the center points of three rectangles in the functional region may be respectively used as the viewpoint data of the functional region, as shown in fig. 4 (c); if the functional region includes three or more rectangles, the position data of the center point of each rectangle may be used as the viewpoint data of the functional region.

The observation point can be located on the ground in the functional area or a certain height from the ground, wherein the height of the observation point relative to the ground in the functional area can be set in a user-defined mode according to requirements, and the embodiment of the invention is not limited.

Referring to fig. 2, in an embodiment, the step 130 may further include:

step 131, obtaining a specific function area of a target type from the function areas of the target house, wherein the target type comprises at least two of a living room, a restaurant, an aisle and an entrance;

step 132, acquiring any two specific function areas with a connection relation, combining three-dimensional spaces of the two specific function areas, and removing a wall body connected between the three-dimensional spaces of the two specific function areas to obtain a combined space;

step 133, in response to that there are some uncombined specific function regions, merging the three-dimensional space of any uncombined specific function region, which has a connection relationship with the current combining space, into the current combining space, and removing the wall connected between the three-dimensional space of the uncombined specific function region and the combining space until all the three-dimensional spaces of the specific function regions are combined completely, or there is no connection relationship between the three-dimensional space of the uncombined specific function region and the current combining space;

and step 134, generating the three-dimensional house space of the target house according to the finally obtained combined space and by combining the three-dimensional space of the specific functional area which is not combined with the combined space and the three-dimensional space of the non-specific functional area.

As described above, in practical applications, the merging process is only performed on the three-dimensional space of a part of the functional regions, and the merging process is not performed on the three-dimensional space of the functional regions partitioned by the solid walls, such as bedrooms and toilets. Therefore, in the embodiment of the present invention, a specific functional area of a target type, which may include, but is not limited to, at least two of a living room, a restaurant, an aisle, and a hallway, may be first obtained from the functional areas of the target house. The type of the functional area may be obtained by parsing and extracting from the original data, for example, for 2D house type data, the type of each functional area may be identified, for 3D house type data, the type of each functional area may be identified through mapping data in each functional area included in corresponding 3D house type data in a VR viewing room, and the like, and the type of the functional area may also be included in the first target data, which is not limited in this embodiment of the present invention.

Taking the living room, the dining room, the aisle and the hallway shown in fig. 3A as an example, any two connected functional areas, such as the living room and the dining room, may be merged first, the three-dimensional space of the living room and the three-dimensional space of the dining room are merged into one three-dimensional space, i.e., the current merged space, and the wall connected between the three-dimensional space of the living room and the three-dimensional space of the dining room is removed from the merged space, so that the three-dimensional space of the living room and the three-dimensional space of the dining room are communicated; furthermore, if the connection relationship exists between the aisle and the current merging space, the three-dimensional spaces of the guest restaurants, namely the current merging space and the three-dimensional space of the aisle, can be merged, and the wall bodies connected between the three-dimensional spaces of the guest restaurants and the three-dimensional spaces of the aisle are deleted in the merged space obtained after merging; secondly, if the vestibule and the current merging space have a connection relation, the current merging space and the three-dimensional space of the vestibule can be merged, and the wall body connected between the three-dimensional space obtained by merging in the previous step and the three-dimensional space of the vestibule is deleted from the merged space obtained by merging. The resulting merged space at this point can be as shown in fig. 3B.

Of course, in the embodiment of the present invention, if there is at least one specific functional area that is not adjacent to each of the other specific functional areas (i.e., there is no connecting wall), then it is not necessary to merge the specific functional area that is not adjacent to each of the other specific functional areas with each of the other specific functional areas.

Therefore, the three-dimensional house space of the target house can be generated according to the finally obtained merged space and by combining the three-dimensional space of the specific functional area which is not merged with the merged space and the three-dimensional space of the non-specific functional area. Of course, in the embodiment of the present invention, if the three-dimensional spaces of all the specific function areas are merged into the merged space, when the three-dimensional house space of the target house is generated, the three-dimensional spaces of the specific function areas that are not merged with the merged space do not need to be merged.

Optionally, in an embodiment, step 132 further may include:

step 1321, merging the first target data of the two specific function areas to obtain first target data of a current merging space, and removing wall data of a connected wall between the two specific function areas from the currently merged first target data;

step 1322 is to generate a three-dimensional space of the two specific functional regions based on the merged first target data.

In the embodiment of the invention, in order to facilitate the automatic combination of the three-dimensional spaces of the specific functional areas when the target house three-dimensional house model is subsequently constructed, the first target data of each specific functional area can be combined while the spaces are combined.

Taking three-dimensional space merging any two specific function areas with a connection relation as an example, merging the first target data of the two specific function areas to obtain the first target data of the current merging space, and removing the wall data of the wall body connected between the two specific function areas from the current merged first target data; and generating three-dimensional spaces of the two specific functional regions based on the merged first target data. For example, when the living room and the restaurant are merged, the wall data of the wall connected to the living room and the restaurant in the first target data of the living room and the restaurant may be removed, and then the first target data of the current merging space may be merged based on the remaining first target data, that is, the wall data of the wall connected between the two specific function areas is removed from the first target data after the current merging.

It should be noted that, in the embodiment of the present invention, when merging the three-dimensional spaces of other specific function regions into the current merging space, referring to the step 1321 and 1322 described above, first target data of a corresponding specific function region and first target data of the current merging space are merged first to obtain merged first target data, and wall data of a wall connected between the corresponding specific function region and the current merging space is removed from the currently merged first target data; the three-dimensional space of the corresponding specific function region and the current merging space is generated based on the merged first target data, so as to obtain the latest merged three-dimensional space, and the specific details may refer to the merging process of the three-dimensional spaces of the two specific function regions, which is not limited in the embodiment of the present invention.

Taking each living room, dining room, aisle and hallway shown in fig. 3A as an example, first target data of two specific function areas, such as the living room and the dining room, are merged, wall data of a wall connected between the living room and the dining room is deleted, remaining wall data is merged into the first target data of the merged space, and further, when the living room, the dining room and the aisle are merged, wall data of a wall connected between the two specific function areas is deleted, and remaining wall data is merged into the first target data of the merged space; secondly, merging the aisle and the entrance of the guest room, deleting the wall data of the wall body connected with the two specific functional areas, merging the rest wall data into the first target data of the current merging space, and finally adding other data except the wall data of all door data, window data and the like contained in the guest room, the restaurant, the aisle and the entrance into the first target data of the current merging space. Thereby obtaining the final merged space and the first target data thereof.

Moreover, in the merging process, the merged space obtained after the merging process may be an independent space, and the corresponding first target data may be separately generated, and the merged space and the first target data thereof may not affect each specific function area and the first target data of each specific function area, that is, the data for constructing the three-dimensional house model of the target house may simultaneously include the first target data of the merged space, the first target data of each specific function area, and the first target data of each non-specific function area. Of course, in the embodiment of the present invention, the first target data for generating the specific functional area of the merged space may be deleted from the data for constructing the three-dimensional house model of the target house according to the requirement, and the embodiment of the present invention is not limited thereto.

For example, a specific functional region may be identified by executing the following pseudo code;

the combination processing can be further carried out through the following pseudo codes;

# merging first target data of a particular functional area

combined_walls＝combine_walls(need_combined_rooms)

combined_doors＝combine_doors(need_combined_rooms)

combined_windows＝combine_windows(need_combined_rooms)

combined_hotspots＝combine_hotspots(need_combined_rooms)

combine_room＝{}

combine_room['walls']＝combined_walls

combine_room['doors']＝combined_doors

combine_room['windows']＝combined_windows

combine_room['hotspots']＝combined_hotspots

decorate_data.append(combine_room)

Here, "combine _ room" may be understood as a data packet containing first target data of the merge space, and the first target data of the merge space may be placed in the decode _ data packet through the above-mentioned decode _ data.

It should be noted that, in the embodiment of the present invention, if the original data includes both 3D house type data and 2D house type data, any one of the 3D house type data and the 2D house type data may be randomly adopted to construct a three-dimensional house space of the target house; or the priority of two kinds of original data under different target houses can be set, and the original data with higher priority is selected to construct the three-dimensional house space of the target house; or the three-dimensional house space of the target house may be constructed based on the 3D house type data and the 2D house type data at the same time, for example, the first target data obtained based on the 3D house type data and the 2D house type data may be considered comprehensively, and for any functional area, the first target data in the same data dimension obtained based on the 3D house type data and the 2D house type data may be merged and deduplicated to generate the first target data of the corresponding functional area, and so on.

In the embodiment of the invention, in order to realize the on-line simulation of decoration effects of different houses under different decoration styles, the data required in scenes of decoration and the like can be extracted from original data such as 3D house type data, 2D house type data and the like of a target house, the original data is calculated and processed, a complete three-dimensional house model for VR decoration is constructed, the accuracy and the integrity of the three-dimensional house model are improved, and the visual effect of subsequent VR decoration is further improved.
