Detailed ways

The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

As shown in Figure 1, the smart home decoration design system provided by the present invention includes functional modules: house type generation module 1, triangular viewing angle presentation module 2, automatic decoration module 3, personalized decoration module 4, background management module 5 and others Functional module6.

The house type generation module 1 is used for opening the existing house type map or importing the house type map and performing automatic identification. If there is a 3D house type model that is already being edited, you can select the file in the house type generation module 1 to directly open the existing 3D house type. For a new project, it is necessary to import the floor plan and automatically identify it, and then generate the corresponding 3D floor model.

The imported floor plan can come from the image file of the floor plan generated by the drawing software, or the floor plan provided by the developer, or from the image file of the floor plan taken by the user himself with an electronic device such as a mobile phone or a pad. House type generation module 1 extracts information such as wall position, wall thickness, door position, and window position from the imported house type map through image processing and pattern recognition technology, and automatically reconstructs the house based on these information 3D model of .

The house type generation module 1 eliminates the need for the user to manually create a house type or copy the house type according to the house type diagram, which greatly reduces the threshold for novice users to decorate houses, and enhances the user's decoration experience. The diversification of sources of floor plans enables novice users who have never renovated a house to start simulating decoration.

The method for the house type generation module 1 to identify the house type is: preprocessing the uploaded house type map to obtain a grayscale image; performing contour detection on the grayscale image; binarizing the grayscale image; corroding and dilating the binary image Finally, edge detection is performed, and the edge image is hough transformed to obtain linear coordinate information, and the coordinate information of the wall is obtained according to the linear coordinate information. Obtaining the coordinate information of the wall also identifies the house type. Wherein, the method for obtaining the threshold T used in the binarization is: performing adaptive threshold segmentation on the area where the outline detected in the grayscale image is located to obtain the wall area; calculating the average gray value W of the wall area and The average gray value O of the area outside the wall; determine the threshold T=(W+O)/2.

In addition, the house type generation module 1 also automatically corrects the length ratio of the recognized house type diagram, utilizes the OCR recognition engine to identify the length of the target object marked in the house type diagram, and sets L _i as the i-th size value recognized by the OCR recognition engine, P _i is the length value in pixels of the target object corresponding to the i-th size value, and N represents the number of sizes recognized by the OCR recognition engine, then the length value Avg per pixel of the entire floor plan is obtained as: Then the length value P _i ^* of the target object corresponding to the i-th size value in pixels after correction is:

Three viewing angles Presentation module 2 provides three viewing angles of 2D, 3D and roaming, and the user can select the desired viewing angle to watch the model according to needs. Among them, the 2D perspective is a routine function, which is to view and decorate the house from the top perspective. The invention improves the 3D viewing angle and roaming viewing angle. Other decoration software on the market can only view and operate from a relatively fixed viewing angle in 3D mode, while the smart home decoration design system of the present invention can perform viewing and decoration operations in a 360-degree, up, down, left, and right direction under a 3D viewing angle, and Walls that block the line of sight will be automatically hidden to achieve the best visual experience. Decoration software on the market has almost no roaming viewing angle mode. The smart home decoration design system of the present invention can roam in the house from the first-person perspective, just like you are standing in your own decorated room to watch and walk around in each room. Realistic textures of floors, tiles, and wallpapers can be viewed up close.

The automatic decoration module 3 is used to automatically complete the decoration according to the three setting conditions of room type, decoration style and decoration total price. The automatic decoration module 3 enables novice users to easily achieve professional decoration effects with only a few simple operations. Firstly, the user sets the type of each room. The room types include: kitchen, living room, bedroom and bathroom; then the user sets the decoration style of the house. There are various decoration styles, which can be set according to needs. There are European style, Chinese style, Mediterranean style, pastoral style and modern simplicity; finally, the user sets the total price of house decoration, which is the total price of all materials and furniture used for automatic decoration. After the three conditions are set, the automatic decoration module 3 searches the model rooms in the decoration database, intelligently combines and calculates multiple sets of decoration schemes matching the three conditions for the user to choose, and the user can switch between different decoration schemes Watch the specific decoration effect. When the user selects a model room for automatic decoration, the automatic decoration module 3 places the furniture in the model room into the current apartment type according to the decoration rules. During automatic decoration, the automatic decoration module 3 will automatically generate a suspended ceiling according to the type and size of the room, which is not available in the existing decoration system.

The automatic decoration module 3 searches the decoration database, and combines multiple sets of decoration schemes matching the conditions. The user browses the decoration scheme, if he does not find a satisfactory decoration scheme, he can re-set the conditions in the automatic decoration module 3, and perform automatic decoration again; 4 to operate.

Personalized decoration module 4 is used for changing decoration materials or furniture. After the user chooses the decoration effect he likes, he can also modify the decoration effect, including changing/arranging furniture, changing wallpaper, changing floor, adjusting lighting and other operations. Arranging furniture means that the user can rearrange the furniture in the room after the house is automatically renovated. Replacing furniture/wallpaper/floor means that the user can replace the furniture/wallpaper/floor in the room after the house is automatically renovated. Adjusting the light means that the user can adjust each light source after the house is automatically decorated. The shape and size of the suspended ceiling, as well as the lighting effect on the suspended ceiling can also be manually adjusted through the personalized decoration module 4.

The background management module 5 is used for managing the information of users and commodities, and provides the functions of registration, login, database and scheme preservation and import. Registration information includes mandatory information such as user name, password, and email address, as well as optional information such as mobile phone number, date of birth, and gender. The user logs in to the smart decoration software system according to the previously registered information, and the user can also log in anonymously. If the user logs in anonymously, the operations and data performed by the user cannot be saved. All the user's operations and data in the smart home decoration design system can be stored in the database as a plan, and the next time you log in, you can directly open the last unfinished plan to continue the decoration. Saving the database scheme means that the user stores the current decoration scheme in the database, and importing the scheme means that the user imports the decoration scheme previously saved in the database.

The functions realized in other functional modules 6 include: decoration list, article collection, decoration sharing and shopping cart. The decoration list refers to a list of all decoration materials and items in the current decoration plan, including the name, manufacturer, unit price, quantity and total decoration price of each material. Item collection means that users store items they are interested in for next use. Decoration sharing means that users can share the renderings of their renovated houses with others through WeChat/Weibo/QQ space. The shopping cart means that users can put the decoration materials they want to buy into the shopping cart for purchase.

As shown in Figure 2, the user first registers and logs in, opens an existing 3D house type or imports a house type map, and the house type generation module 1 identifies the house types in the imported house type map, and generates a corresponding 3D house type model. The user sets the room type, decoration style and total decoration price, and the automatic decoration module 3 searches the database for storing commodities, and combines multiple sets of decoration schemes matching the conditions. The user browses the decoration scheme, if he does not find a satisfactory decoration scheme, he can re-set the conditions in the automatic decoration module 3, and perform automatic decoration again; 4 to operate. Through the personal decoration module 4, it is possible to change/arrange furniture, change wallpaper, change floors, arrange or add lights and so on. After the decoration is completed, save the decoration plan and generate a decoration list. If you want to buy furniture you like, you can add the goods to the shopping cart and go to the mall for settlement.

The most important innovation point of the present invention is to automatically decorate the imported 3D apartment-type rooms, and the realization of the function of the automatic decoration module 3 will be described in detail below.

First of all, the functional requirements of the automatic decoration module 3 are as follows:

Requirement 1: The items in the model room of the overall apartment type are respectively imported into the corresponding new apartment type room;

Requirement 2: A complete decoration plan for combining some model rooms into a new apartment type.

Before realizing the function of automatic decoration, a decoration database needs to be established. The decoration database mainly includes the following three parts, the first is furniture and building materials, the second is the designed model room, and the third is the model house type.

Furniture belongs to soft decoration, while building materials belong to hard decoration. Building materials include wallpaper, wall covering, floor tiles, wall tiles, latex paint, curtains, floors, etc. For furniture and building materials, the set attributes include product number, product brand, product length, width and height, product color, product material, product price, product description, etc., among them, if an attribute does not exist, the attribute value is set It is empty, for example, the length, width, and height of the dye are set to be empty.

For the model room, the set attributes include model room number, room information, room type, decoration style, room furniture information, room building material information, and room decoration price, etc. Room information includes room number, apartment type number, room height, number of room vertices, set of room vertices, door information, window information, etc. The room type can be obtained through the vertex collection of the room. As shown in Figure 3, there are types A~I, where A is a regular rectangular room with 4 vertices; B~E are L-shaped apartment types in different directions, all of which have 6 vertices; F～I are T-shaped houses in different directions, all of which have 8 vertices. For the room, it is described by a set of vertex coordinates, starting from the upper left corner as the first vertex, and describing the remaining vertices in a clockwise direction. Gate information includes the number of gates and the set of vertex coordinates of each gate. Window information includes the number of windows and the set of vertex coordinates of each window. There are many types of rooms, including living room, master bedroom, second bedroom, children's room, elderly room, princess room, kitchen, dining room, kitchen, bathroom, balcony, storage room, hallway and corridor, etc. There are many decoration styles, including modern simplicity, European style, Chinese style, Mediterranean style and pastoral style, etc. The room furniture information includes the product number, the three-dimensional coordinates of the center of the bottom surface of the furniture in the sample room, and the placement angle, where the placement angle refers to the clockwise rotation angle with north as the reference. The placement angles of walls, doors, windows, and furniture are also clockwise rotation angles with reference to the north direction. For Figure 3, there are four main placement angles: 0 degrees for the back to the north wall, and 0 degrees for the back to the east. The angle of placing the wall is 90 degrees, the angle of placing the back against the south wall is 180 degrees, and the angle of placing the back against the west wall is 270 degrees. Room building material information mainly includes commodity numbers. The total price of hard decoration is calculated according to the room area, and the total price of soft decoration is obtained by counting the unit price of placed furniture. The room decoration price is obtained by counting the total price of furniture and building materials in the model room. Design more than two decoration schemes with different prices for model rooms of different room types under different decoration styles.

The model house type is formed by combining the model rooms, and the model house type has as many rooms as there are rooms. For the model house type, the set attributes include model room number, total area, house type name, decoration style and total decoration price. Select representative one-bedroom, two-bedroom, three-bedroom and other apartment types, and organically combine eligible model rooms to form model apartment types according to the decoration style and total decoration price. In the decoration database, there are multiple sets of model apartment types with different decoration styles and different decoration total prices.

For requirement 1, during automatic decoration, when the decoration style is determined, the area of the current user’s apartment type is obtained, and the model apartment types with the same or similar area are searched, or the model apartment types belonging to the same apartment type are selected. The model apartment type is prioritized in the front, and the model rooms of the same style corresponding to the room are arranged in the front, so that users can choose and directly import the decoration plan of the model room.

For the second requirement, the specified room is individually decorated, and the qualified ones are selected from the existing model rooms according to the setting conditions, such as decoration price, room area, and decoration style, and then the decoration plan of the model room is imported.

When putting a product into the decoration database, it is necessary to collect the picture data of the product, for example: pictures of a certain type of furniture before and after opening, closing, and placing things, such as wardrobes; pictures from different angles such as front, left, and right sides ; before and after folding; combination pictures, such as sofa combination placement: footrest, chaise longue, single, double, three-person, etc.; furniture sitting before and after people, such as dining table and chairs. For the same product, such as a sofa, it is necessary to collect pictures of different sizes, different prices, and different colors.

Because the product is placed flat, the background color of the collected product is transparent, and some adjustments are made to the placement position according to the coordinates and item size. The collision detection can be realized based on the webgl library.

The intelligent home decoration design system provided by the present invention pre-sets an intelligent decoration sequence, and combines the products for decoration in the order of kitchen engineering, bathroom engineering, lighting, wall and floor, bedroom, living room, balcony and study, forming a style that meets certain style requirements. , Home improvement plan within the budget.

The selected model apartment or model room is automatically decorated for the current apartment type room, that is, the furniture and building materials in each model room are imported into the user's own corresponding apartment type room. For hard decorations such as wallpapers, floors, background walls and other building materials, they are directly paved in the same way as in the model room. For furniture, the present invention intelligently calculates each piece of furniture in the room corresponding to the current user according to the decoration rules based on ergonomics. to place the furniture in the new location. Finally, recalculate the price of hard decoration according to the area of the user's room, and calculate the total price of soft and hard decoration in the current user's apartment.

Firstly, the decoration rules based on ergonomics are explained, mainly to check whether the new position in the user's own apartment conforms to the comfortable distance of ergonomics, mainly including human body scale, human behavior area, common furniture and equipment size, architectural scale specifications, and visual Psychology and space (symmetry, beauty, practicality, convenience) and other aspects. The decoration rules mainly include: the rationality and comfort constraints of furniture placement; matching decoration style; matching colors; furniture association rules. There are also decoration rules such as decoration construction sequence, construction technology, and construction precautions. Among them, the rationality and comfort constraints of furniture placement mainly include the following aspects:

(1) After the furniture is put in, the furniture door will not affect people to continue to pass through;

(2) Convenience of maintenance and use: such as the relationship between the placement of cabinets, the relationship between the height of the hanging cabinet and the height of the person;

(3) The relationship between the optimal hanging height of the chandelier and the illuminated area and room area;

(4) The distance between the dining table and the wall, the movement distance of a person sitting on the dining chair and stretching his legs, and the comfortable distance from the dining table;

(5) The location, angle and order of furniture placement of different sizes, such as when a certain type of decoration supplies are not in use temporarily or are not included in the decoration list, for example, there are three combined cabinets, high, middle and low. Only medium and low bookcases are selected, how to adjust the relative placement of subsequent furniture pictures in the decoration plan, if only high and low bookcases are selected, should they be placed together or other placement schemes;

Each decoration plan has a furniture list and a hard decoration list. If the overall style of the hard decoration changes, it will become another decoration plan. After several pieces of furniture and their position relationship are changed, it is also defined as another decoration scheme.

Obtain the information of each room in the user's own house type through the house type generation module 1, and store in the user's room table, the room information includes room number, house type number, room height, room area, room vertex number and vertex coordinate set, door information and window information. Among them, the information of doors and windows can be stored in a separate table and linked by room number. When the apartment type generation module 1 generates a 3D model, the following operations are performed on each room of the user: calculate the length and width of the room according to the vertices of the room; set the name of each window and the angle of the window according to the window list; Calculate the width of the window; set the name of each door and the angle of the door according to the door list, calculate the width of the door according to the two vertices of the door; construct the wall according to each two vertices of the room, set the name of the wall and the angle of the wall, according to The two vertices of the wall calculate the width of the wall; calculate the adjacent relationship of doors and windows on the same wall.

Specifically, the method for the automatic decoration module 3 to import furniture from a model room into the user's room is shown in FIG. 4 .

Step 1: Obtain the furniture list of the model room;

Step 2: Read the user's room information, and obtain the room's vertex set, window information and door information, as well as the adjacent relationship between doors and windows on the same wall through the apartment type generation module 1;

Step 3: For the user's room, output the decoration rules of furniture and doors, furniture and windows, furniture and walls.

In the decoration rules for furniture and doors, the horizontal distance space between furniture and doors, as well as the minimum vertical distance minspace and maximum vertical distance maxspace between furniture and doors are recorded, as shown in Figure 5A, F1 represents furniture. Minspace refers to the vertical distance between the furniture and the wall where the door is placed after the furniture is placed on the left or right of the door, and people are not allowed to walk between the furniture and the wall. maxspace means that after the furniture is placed on the left or right of the door, the vertical distance from the wall where the door is located allows a person to walk between the furniture and the wall without any problem.

In the decoration rules of furniture and windows, the horizontal distance space between furniture and windows, and the two vertical distances minspace and maxspace between furniture and windows are recorded. Similarly, minspace means that after the furniture is placed, the vertical distance from the wall where the window is located does not allow people to walk between the furniture and the wall. Maxspace means that after the furniture is placed, the vertical distance from the wall where the window is located allows a person to walk between the furniture and the wall without any problem.

For walls that do not contain doors or windows, the furniture and wall decoration rules record the horizontal distance space between furniture and a vertex of the wall, and two vertical distances minspace and maxspace from the wall. Similarly, minspace means that after the furniture is placed, the vertical distance from the wall does not allow people to walk between the furniture and the wall; maxspace means that after the furniture is placed, the vertical distance from the wall allows a person to walk between the furniture and the wall without any problem.

Since there are two vertical distances, when the furniture is placed, it has two new positions under different placement angles.

Step 4: According to the decoration rules, put the furniture in the model room into the user's room one by one. If the furniture is placed successfully, obtain the center coordinates of the bottom surface of the furniture in the user's room; if the furniture is placed in violation of the decoration rules, the furniture placement is unsuccessful.

When placing in a new room, some furniture has no direction. For example, the shape of the furniture is square, hexagonal, round, etc. No matter which direction it faces, the effect of final placement is the same. Some furniture has two directions. For example, the shape of the furniture is rectangular, and the effect of placing it horizontally and vertically is different. Some furniture has four orientations, such as a sofa with a backrest, after defining a new position, different orientations are different placement situations, for example, if the sofa is against the north wall, it can be placed on the left or right side of the door, if the door is placed On the left, the furniture has 3 placement angles, which are 0, 90, and 270.

For the furniture in a certain room, the furniture close to the door, window and wall should be placed first; the furniture not close to the door, window and wall in the model room needs to calculate the new position according to the priority furniture that has been placed.

According to the door, as shown in Figure 5, the furniture may be placed on the left or right of the door, expressed as <door number, left or right, whether there is furniture already placed>, when furniture is placed on a certain side of the door , the new position of the furniture is <door number, left or right, <placement angle, center coordinates of the furniture bottom>>. For example, there are possible placement positions: <door 1, left, yes>, yes means it can be placed, no means it cannot be placed, then the new position of the furniture is <door 1, left, <placement angle, center coordinates of the bottom of the furniture >>.

According to the window, as shown in Figure 6, the furniture may be placed on the left side of the window, right side of the window or in front of the window, expressed as <window number, left side or right side or front side, whether there is furniture already placed>. There are two situations in which the length of the furniture placed in front of the window is larger or smaller than the width of the window, but the position of the center point of the bottom surface of the calculated furniture is the same.

According to the wall, as shown in Figure 7, the furniture may be placed in the space from the right vertex of the wall, the space from the left vertex of the wall, and the middle of the wall, expressed as <wall number, the horizontal distance from the wall to the left vertex The horizontal distance from the space or the wall to the right vertex is the space or the middle of the wall, whether there is furniture placed >.

For the placement of the remaining furniture that is not close to the door, window or wall, the new coordinates of the furniture to be placed are calculated according to the possible placement relationship between the furniture.

For example, for the furniture in the living room: sofa, coffee table, TV cabinet and wine cabinet; among them, the set A={sofa, TV cabinet, wine cabinet} is a collection of furniture placed against the wall; the set B={tea table} is not against the wall The collection of furniture; first place the furniture in collection A, and then place the furniture in collection B.

For example, for furniture in a restaurant, the placement rules are: the furniture placed against the wall is prioritized and the furniture placed in the middle of the restaurant is prioritized; the furniture not placed against the wall is based on the positional relationship and Place them in sequence at a suitable distance or around the items in collection A; for example, place the dining table first and then the dining chairs.

For example, for the furniture in the bathroom, since the toilet drain is fixed, the shower room (or bathtub), bathroom cabinet (with basin, bathroom mirror), and toilet are all against the wall, but the toilet needs to be placed first, and then the shower room needs to be moved Move the room or bathroom cabinet to other locations against the wall to prevent drainage inconvenience.

Step 5: For furniture that is unsuccessfully placed, judge whether it can be successfully placed by adjusting the size. If so, adjust to the corresponding size for placement, otherwise give up the placement.

For example, a desk cannot be placed successfully due to its large size. Check whether the desk can be replaced with a small size.

For example, the three furniture F1, F2, F3 in the model room shown in FIG. 8 are imported into the user room as shown in FIG. 9 . The room in Fig. 9 is a rectangular room with four walls Wall1-Wall4. Wall Wall1 has two doors Door1, Door2 and a window Window1, and wall Wall2 has a door Door3 and a window Window2.

Arrange the furniture according to the positional relationship in the model room, and calculate the new coordinates of the furniture. For example, the furniture F1, F2, and F3 in the currently used model room are arranged in a row, and they are also arranged in a row in the user's room. There are four types Placement effect: F3 has directions, and the placement angle of F3 is 0, 90, 180, 270, then F1 and F2 are calculated according to the coordinates of F3.
