[0055] The embodiments of the present invention provide a method for quickly drawing and automatically trimming a simple floor plan based on gestures, a device for quickly drawing and automatically trimming a simple floor plan based on gestures, an electronic device and a storage medium, which are used to solve or partially solve the technical problems that the existing floor plan drawing process is relatively complicated, the operation is not simple enough, and the drawing efficiency is not high enough.

[0056] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] As an example, existing floor plans are mainly drawn with the help of computer-aided design or other online drawing methods. Most of them are concentrated in application fields such as home decoration, construction, and fire protection. Although such drawing methods have high drawing effects and accuracy, they generally have problems such as relatively complex processes, high entry barriers, and long drawing time, which makes the delivery difficulty of installation and maintenance personnel increase exponentially.

[0058] Based on this, the present invention believes that there is an urgent need for an online floor plan drawing solution that is simple to operate, has high drawing efficiency, and can basically present the layout of a house.

[0059] Therefore, one of the core invention points of the embodiment of the present invention is: in order to help installation and maintenance personnel to efficiently and simply draw the user's house floor plan, a method for fast drawing and automatic trimming of a simple floor plan based on gestures is proposed. First, multiple rooms are drawn one by one in the grid square matrix pre-constructed in the graphic display interface through gestures, so that when drawing the floor plan, there is no need to draw walls, but the outline of a single or multiple rooms is drawn according to the trajectory of the finger sliding on the screen and the rectangular area occupied by the screen; then the room with the largest area is taken as the base point room, and the room gaps of each room are automatically adjusted based on the gaps in the cross direction, so that multiple rooms are automatically adjusted according to the base point room, and the room gaps can be automatically eliminated; then based on the center point of the base point room, combined with the center point path distance calculation, each room is automatically trimmed to open doors and windows, so that doors and windows are automatically opened based on the path distance between the base point room and other rooms, and the door and window positions can be automatically calculated according to the layout of the floor plan and presented on the floor plan; finally, according to the gesture sliding, the room with a wall intersecting with the base point room is fine-tuned to obtain the final simple floor plan.

[0060] The technical solution of the present invention reduces the difficulty of drawing house plans and improves the drawing efficiency by providing an efficient and simple solution for rapid drawing and automatic trimming of simple house plans. By adopting the technical solution of the present invention, in actual applications, installation and maintenance personnel can master the drawing of house plans through simple training. Based on gestures and trajectories, combined with the logic of automatic trimming of the house structure, the outlines of common house types such as one bedroom and one living room, two bedrooms and one living room, and three bedrooms and two living rooms can be drawn within 3 minutes, thereby efficiently and accurately drawing a complete simple house plan that roughly matches the actual house type. Compared with existing drawing methods, the technical solution adopted by the present invention can greatly reduce the threshold for use.

[0061] Reference Figure 1 , shows a flowchart of a method for quickly drawing and automatically trimming a simple floor plan based on gestures provided by an embodiment of the present invention, which may specifically include the following steps:

[0062] Step 101, drawing a plurality of rooms one by one in a pre-constructed grid matrix on a graphic display interface through gestures;

[0063] Gesture refers to sliding your finger on a screen with a touch screen function such as a mobile phone or tablet. In a specific implementation, the graphical display interface can be an H5 page. Before drawing a room, you can draw a grid matrix of a preset size (such as 400*400) on the H5 page, and set the grid squares in the grid matrix to be dragged, enlarged or reduced according to the gesture. That is, the grid squares have the ability to be dragged, enlarged and reduced according to the screen gesture.

[0064] At the same time, default attributes can also be filled in for each grid square. Among them, the default attributes include square ID, edge type and direction identifier. Furthermore, edge types can mainly include non-edges, walls, doors, and windows. Direction identifiers can mainly include four directions: east, south, west, and north. For the screen, from the user's perspective, it can also be seen as the four directions of up (north), down (south), left (west), and right (east). In the specific example, the default attributes filled in each grid square are:

[0065] {Square ID, edge type: {0: non-edge 1: wall 2: door 3: window}, direction identifier: east, south, west, north}

[0066] Specifically, the drawing process of each room can be as follows: first, taking the first touch point in the grid matrix through a gesture as the origin, calculate the continuous x-axis coordinate data and y-axis coordinate data of the touch point as the gesture slides; secondly, according to the x-axis coordinate data and the y-axis coordinate data, calculate the x-axis minimum value min(x), x-axis maximum value max(x), y-axis minimum value min(y), and y-axis maximum value max(y) in the coordinates; finally, according to the x-axis minimum value min(x), x-axis maximum value max(x), y-axis minimum value min(y), and y-axis maximum value max(y), draw a room in the grid matrix.

[0067] For example, Figure 2 A schematic diagram of an interface for drawing a single room provided by an embodiment of the present invention is shown.

[0068] Figure 2 It can be regarded as the first step in drawing a simple floor plan, that is, drawing a single room. Figure 2 , when drawing a single room:

[0069] Take the first touch point as the origin and calculate the continuous x and y coordinate data when the touch point slides;

[0070] Calculate the four values ​​of the coordinates: min(x), max(x), min(y), and max(y);

[0071] Draw a rectangular room based on the above four values.

[0072] It is understandable that in actual situations, the drawn room is not necessarily a rectangle, but may just be a square. Since a square is a special case of a rectangle, for ease of description, the drawn rooms are all regarded as rectangular rooms.

[0073] For example, Figure 3 A schematic diagram of an interface for drawing multiple rooms provided by an embodiment of the present invention is shown.

[0074] Figure 3 This can be regarded as the second step of drawing a simple floor plan, that is, drawing multiple rooms. When drawing each room, just refer to the single room drawing method. I will not go into details here.

[0075] Assumption Figure 3 After a quick drawing of Figure 3 The first picture from left to right above), bathroom (corresponding to Figure 3 The second picture from the left above), kitchen (corresponding to Figure 3 The third picture from the left above) and the living room (corresponding to Figure 3The rooms with the largest area are shown below.

[0076] Among them, when drawing multiple rooms, if the intersection of the currently drawn room and other rooms will "invade" these rooms, and the midpoints of the matrix of the overlapping part have been marked by these rooms, you can adopt the direct overwriting marking method to complete the drawing.

[0077] Specifically, during the process of drawing multiple rooms, if the current drawing room overlaps with the historical drawing room, and the overlap matrix has been marked by the historical drawing room, the overlap matrix is ​​directly covered and marked as part of the current drawing room. The current drawing room refers to the room currently being drawn. The historical drawing room refers to the room drawn before the current drawing room.

[0078] Step 102, taking the room with the largest area as the base room, merging the gaps in the cross direction, and automatically adjusting the room gaps of each room;

[0079] In a specific implementation, the room with the largest area is taken as the base room, and the gaps in the cross direction are merged to automatically adjust the gaps between the rooms. The process can be as follows:

[0080] The room with the largest area is regarded as the base room, and the rooms other than the base room are regarded as common rooms;

[0081] Calculate the gaps between each common room and the base point room in each direction in the four directions of east, south, west and north of the base point room;

[0082] For any single direction of the east, south, west, or north (or any single direction of the four directions of up, down, left, or right in a more popular sense) centered on the base room:

[0083] Taking the maximum gap calculated in a single direction as the moving distance, all common rooms in a single direction are translated toward the base point room to connect with the base point room;

[0084] Determine the target common room with the smallest distance difference from the base point room in the cross direction in a single direction; the distance difference in the cross direction indicates the distance difference between the length of the same side of a single common room in a single direction and the base point room in the cross direction; the single direction and the cross direction are perpendicular to each other;

[0085] Taking the target common room as the base point for movement in the cross direction, the common rooms other than the target common room in a single direction are translated toward the target common room to merge the gaps in the cross direction, and the gaps between two adjacent common rooms in a single direction are automatically eliminated;

[0086] If the minimum distance difference between the target ordinary room and the base point room in the intersection direction is less than 1 / 10 of the length of the side of the base point room connected to the target ordinary room, the target ordinary room will be translated in the direction of shortening the minimum distance difference to align the target ordinary room with the base point room.

[0087] In order to enable those skilled in the art to better understand this step, following the above example, Figure 4 A schematic diagram of an interface for automatically adjusting the room gaps between multiple rooms provided by an embodiment of the present invention is shown.

[0088] Figure 4 It can be seen as the third step of drawing a simple floor plan, that is, the process of merging rooms in automatic trimming, and it can also be seen as the process of automatically adjusting the gaps between rooms.

[0089] Combination Figure 3 , take the living room, the largest room, as the base room. Calculate the gaps between other rooms and the living room in four directions: up, down, left, and right. For example Figure 3 , taking the living room as the base room, the bedroom, bathroom and kitchen are just above the living room. Assume that after calculation, the bedroom is 2 away from the living room, the bathroom is 3 away from the living room, and the kitchen is 5 away from the living room. Then the maximum gap between the living room and other rooms in the "upward" direction is 5. Figure 4 In the example, the three rooms (bedroom, bathroom, kitchen) in the "upward" direction are moved downward as a whole to connect with the living room with a maximum gap of 5. To better match the design of a real house, after the three rooms are moved downward as a whole to connect with the living room and embedded, the edges of the bedroom, kitchen and living room that are tangent to each other can be adjusted to be on the same straight line (that is, the bottom edge of the four sides of the bedroom is flush with the bottom edge of the four sides of the kitchen).

[0090] In addition to the base room, other ordinary rooms in a single direction are merged in the cross direction. First, calculate the room with the smallest cross direction distance difference from the base room in a single direction, and use this room as the base point for the cross direction movement. Other rooms in the same direction are moved closer to this room. For example Figure 3 Assuming that the left distance between the bedroom and the living room is 1, and the right distance between the kitchen and the living room is 3, then take the bedroom as the base point for horizontal movement (i.e. the cross direction at this time), and move the bathroom and kitchen to the left to align and eliminate the gap between the rooms.

[0091] Step 103, based on the center point of the base point room and in combination with the center point path distance calculation, automatically trim each of the rooms;

[0092] In a specific implementation, each room is automatically trimmed based on the center point of the base room and combined with the center point path distance calculation, which can be as follows: first calculate the center point of the base room; for the base room, open the door on any wall with the longest path from the center point; for each ordinary room adjacent to the base room, open the door on the wall with the shortest path from the center point, and open the window on the wall with the longest path from the center point.

[0093] Fig. 5 (a) shows a schematic diagram of an interface for opening doors of multiple rooms. Fig. 5 (b) shows a schematic diagram of an interface for opening windows of multiple rooms.

[0094] Figure 5 (a) and Figure 5 (b) can be regarded as the fourth step of drawing a simple floor plan, that is, the process of opening windows and doors in automatic trimming. This process actually automatically opens doors and windows based on the distance between the base room and the wall path of other rooms. Combined with Figure 5 (a) and Figure 5 (b), when opening doors and windows in a room:

[0095] First calculate the center point of the living room;

[0096] For rooms adjacent to the living room (bedroom, bathroom, kitchen), open the door on the shortest path to the center of the living room;

[0097] For rooms adjacent to the living room (bedroom, bathroom, kitchen), windows should be opened on the wall farthest from the center point of the living room.

[0098] In addition, for the living room, the door opening operation can also be performed on any wall with the longest path from the center point, such as on the left side of the longer short side.

[0099] In another case, the door opening operation can also be performed on the wall with the shortest path from the center point. As shown in FIG5(b), the door opening operation is performed on the wall with the opposite long side length between the living room and each room (i.e., the lower side among the four sides of the living room).

[0100] Based on the previous steps, Figure 6 FIG. 1 shows a schematic diagram of a room interface obtained after drawing. Figure 6 It can be seen that after opening the doors and windows, the width of the windows in the bedroom and kitchen is 600mm (millimeters). Since the bathroom has a smaller area, its window width can be set to 300mm for a more realistic house design. The door widths of the bedroom, bathroom, and kitchen are all 390mm. Since the door of the living room is the main door of the entire house, it can be set wider, such as 1280mm.

[0101] It should be noted that Figure 5(b) and Figure 6The relevant dimension values ​​of the doors and windows of the house are only used as an example. For the specific dimension values ​​of the doors and windows of each room, those skilled in the art can reasonably set them according to the actual situation. It is understood that the present invention is not limited to this.

[0102] Step 104, according to the gesture sliding, fine-tune the room whose wall intersects with the base point room to obtain the final simplified floor plan.

[0103] Furthermore, according to the gesture sliding, the rooms where the walls intersect with the base room are fine-tuned to obtain the final simple floor plan. The final simple floor plan can be as follows: within the range of the base room, according to the finger sliding range in the gesture sliding, the rooms where the walls intersect with the base room are adjusted to adjust the wall position of the wall intersection room to coincide with the wall position of the base room, to obtain the final simple floor plan.

[0104] by Figure 6 For example, combined with the previous related drawing process, the edge where the bathroom and the living room meet is used as the reference calibration edge. In fact, the bedroom and kitchen both have walls intersecting with the living room. At this time, you can slide your finger in the living room, place your finger below the bedroom (when adjusting the bedroom) or the kitchen (when adjusting the kitchen), and slide your finger upward. At this time, the wall positions of the bedroom and kitchen will be adjusted according to the finger sliding range, so that they coincide with the wall position of the living room (that is, it is equivalent to manually adjusting the walls of the bedroom and kitchen to align with the walls of the living room), and obtain the final simple floor plan.

[0105] For another example, suppose that after the drawing steps, the bathroom and the living room finally have walls that intersect. At this time, you can slide your finger under the bathroom in the living room and slide it upward. At this time, the bathroom wall position will be adjusted according to the finger sliding range to make it coincide with the living room wall position (that is, it is equivalent to manually adjusting the bathroom wall to align the living room wall), and the final simple floor plan will be obtained.

[0106] In an embodiment of the present invention, a method for fast drawing and automatic trimming of a simple floor plan based on gestures is proposed. First, multiple rooms are drawn one by one in a grid matrix pre-constructed in a graphic display interface through gestures, so that when drawing a floor plan, there is no need to draw walls, but the outlines of a single or multiple rooms are drawn according to the trajectory of the finger sliding on the screen and the rectangular area occupied by the screen; then the room with the largest area is taken as the base point room, and the room gaps of each room are automatically adjusted based on the gaps in the cross direction, so that multiple rooms are automatically adjusted according to the base point room, and the room gaps can be automatically eliminated; then based on the center point of the base point room, combined with the center point path distance calculation, each room is automatically trimmed to open doors and windows, so that doors and windows are automatically opened based on the path distance between the base point room and other rooms, and the positions of doors and windows can be automatically calculated according to the floor plan layout and presented on the floor plan; finally, according to the gesture sliding, the room with a wall intersecting with the base point room is fine-tuned to obtain the final simple floor plan.

[0107] The technical solution of the present invention reduces the difficulty of drawing house plans and improves the drawing efficiency by providing an efficient and simple solution for rapid drawing and automatic trimming of simple house plans. By adopting the technical solution of the present invention, in actual applications, installation and maintenance personnel can master the drawing of house plans through simple training. Based on gestures and trajectories, combined with the logic of automatic trimming of the house structure, the outlines of common house types such as one bedroom and one living room, two bedrooms and one living room, and three bedrooms and two living rooms can be drawn within 3 minutes, thereby efficiently and accurately drawing a complete simple house plan that roughly matches the actual house type. Compared with existing drawing methods, the technical solution adopted by the present invention can greatly reduce the threshold for use.

[0108] For better explanation, refer to Figure 7 , showing a schematic diagram of the overall process of a method for quick drawing and automatic trimming of a simple floor plan based on gestures provided by an embodiment of the present invention. It should be pointed out that this embodiment only briefly describes the general process of quick drawing and automatic trimming of a simple floor plan based on gestures. The specific implementation process of each step can be understood by referring to the relevant content in the aforementioned embodiment, which will not be described here. It can be understood that the present invention does not limit this.

[0110] Step 702: Draw multiple rooms one by one in the grid matrix through gestures;
