[0024] With reference to the drawings and the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly described. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art are within the scope of protection of the present application.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the objects before and after are in a "or" relationship.

[0026] The house type drawing processing method, device, electronic equipment and storage medium provided by the embodiments of the present application will be described in detail below in combination with the drawings and specific embodiments and application scenarios.

[0027] In some embodiments of the present application, a house type drawing processing method is provided, Figure 1 A flowchart of a house type drawing processing method according to an embodiment of the present application is shown in FIG. 1. Figure 1 As shown in FIG. 1, the house type drawing processing method comprises:

[0028] In step 102, the house type drawing to be processed is preprocessed to obtain a target image, the content of the target image includes a target object, and the target object includes a plurality of object regions.

[0029] In step 104, a first contour of the target object is determined.

[0030] In step 106, a second contour of the plurality of object regions is determined.

[0031] In step 108, the target house type drawing is generated according to the first contour and the second contour.

[0032] In the embodiments of the present application, for online house viewing scenarios, users can display house type drawings through electronic devices such as mobile phones and tablet computers. For different electronic devices, their software and hardware are different, in order to adapt to the display screens of different electronic devices, the house type drawings will be compressed or enlarged.

[0033] In the related art, the house type drawing is manually drawn by a draftsman, and is saved in the form of a picture after being drawn, so that when the picture house type drawing is scaled, the house type drawing display will be blurred and other problems will occur.

[0034] To address the aforementioned issues, this application vectorizes the floor plan based on its overall outline and internal room outlines. The vectorized floor plan remains undistorted and unblurred regardless of whether it is scaled or not.

[0035] Specifically, the floor plan to be processed is the floor plan drawn by the draftsman. After obtaining the floor plan to be processed, the first step is to preprocess it. Specifically, the preprocessing steps can be to remove useless parts of the floor plan, such as decorative patterns and background colors, to obtain a relatively clean line floor plan, which is the target image.

[0036] The target image includes the target object, which is the property shown in the floor plan, such as a unit with an area of ​​100 square meters. 2 The target property includes multiple areas, which are the various rooms within the property, including the porch, entryway, living room, bedroom, and bathroom.

[0037] The first outline of the current property as a whole and the second outline of each room in the current property are drawn separately. Both the first and second outlines are drawn in vector form. In the final target floor plan, the overall outer outline and the internal room outlines are vectorized line segments or curve segments. Therefore, a vectorized floor plan can be obtained. When displaying the vectorized floor plan, no image distortion or blurring will occur, regardless of whether the floor plan is compressed or enlarged, thus improving the display effect of the floor plan.

[0038] In some embodiments of this application, determining the first contour of the target object includes:

[0039] Identify the outer contour of the target object and obtain multiple outer contour feature points of the target object;

[0040] The outer contour curve of the target object is obtained by fitting multiple outer contour feature points;

[0041] The outer contour curve is smoothed to obtain the first contour.

[0042] In this embodiment of the application, the first outline is the overall outline of the property shown in the current floor plan. Figure 2 A schematic diagram of a first outline according to an embodiment of this application is shown, as follows. Figure 2 As shown, when drawing the first contour, image recognition is first performed on the preprocessed floor plan, that is, the target object 202 in the target image 200. Specifically, edge detection is performed on the target object, and feature points on the edge of the target object are obtained through the edge detection algorithm, which are denoted as outer contour feature points 204.

[0043] The contour feature points 204 are fitted to obtain a curve, i.e., a contour curve 206 of the target object. It can be understood that the contour curve can be a closed curve or an open, non-closed curve, and the embodiments of the present application do not limit this.

[0044] The fitted contour curve is further smoothed to obtain a first vectorized contour.

[0045] The embodiments of the present application vectorize the overall contour of the house type diagram, i.e., the first contour, and the vectorized target house type diagram after processing will not be blurred or distorted when displayed at any resolution, thereby improving the display effect of the house type diagram.

[0046] In some embodiments of the present application, the second contour of the plurality of object regions is determined, including:

[0047] According to the shape of each object region in the plurality of object regions, a corresponding region graph is generated in each object region, and the area of the region graph is less than the area of the object region;

[0048] Each region graph in the plurality of region graphs is enlarged at a constant ratio until at least one side of each region graph intersects at least one side of at least one other region graph.

[0049] The second contour is determined according to the plurality of region graphs after the constant ratio enlargement.

[0050] In the embodiments of the present application, after the pre-processing of the house type diagram to be processed, a target image is obtained, the target image includes a target object, i.e., a house property displayed by the house type diagram, and the target object includes a plurality of object regions, each of which corresponds to a room in the house property.

[0051] Since the shapes of these rooms can be different and irregular, a region graph is first drawn in each room, Figure 3 A schematic diagram of the second contour according to the embodiments of the present application is shown in FIG. 3. Figure 3 As shown in FIG. 3, the shape of the region graph 3022 is the same as that of the corresponding object region 302, and the area of the region graph is less than that of the object region.

[0052] Meanwhile, the region graphs 3022 are enlarged at a constant ratio. During the enlargement of the region graphs 3022, adjacent region graphs approach each other, and when a region graph intersects with the side of another region graph, the enlargement of the two region graphs is stopped until each region graph contacts at least one other region graph.

[0053] At this time, adjacent region graphs in the plurality of region graphs drawn share a side, as shown in FIG. 3. Figure 3As shown, there is a common edge 308 between the first region graph 304 and the second region graph 306.

[0054] According to the edges of the plurality of region graphs after the enlargement, the second contour of each object region, i.e., each room, can be determined.

[0055] Embodiments of the present application draw region graphs with the same shape as the rooms, and obtain rooms matching the shape, size and position of the real rooms by inflating the region graphs, so as to accurately draw the contours of the rooms, and finally generate vectorized rooms, which can avoid the problems of display distortion and blur when the house type diagram is scaled.

[0056] In some embodiments of the present application, determining the second contour according to the plurality of region graphs after the equal-scale enlargement comprises:

[0057] determining a graph contour curve of each of the plurality of region graphs;

[0058] performing smoothing processing on the graph contour curve to obtain the second contour.

[0059] In embodiments of the present application, after the plurality of region graphs are enlarged, a graph contour curve of each of the enlarged region graphs is determined, which is a curve formed by the edges of the region graph. It can be understood that the graph contour curve can be a closed curve, i.e., the outer edges of the region graph form a closed shape. The graph contour curve can also be an open curve, which is not limited in embodiments of the present application.

[0060] Performing smoothing processing on the graph contour curve of each of the region graphs, i.e., each room, can obtain the vectorized second contour.

[0061] Embodiments of the present application vectorize the contour of each room in the house type diagram, i.e., the second contour. The processed vectorized target house type diagram will not be blurred or distorted when displayed at any resolution, which can improve the display effect of the house type diagram.

[0062] In some embodiments of the present application, before determining the second contour according to the plurality of region graphs after the equal-scale enlargement, the method further comprises:

[0063] In a case where the first region graph and the second region graph in the plurality of region graphs satisfy that at least part of the first region graph and at least part of the second region graph coincide, a coincident region graph of the first region graph and the second region graph is determined;

[0064] In a case where the area of the coincident region graph is greater than an area threshold, the coincident region graph is determined as a new region graph;

[0065] In a case where the area of the overlapping region pattern is less than or equal to the area threshold, the overlapping region pattern is deleted in the first region pattern or the second region pattern.

[0066] In the embodiments of the present application, when the region patterns corresponding to the plurality of object regions are scaled up at a same scale, there may be a case where the scaled-up region patterns at least partially overlap with other region patterns. If the first region pattern and the second region pattern overlap, the overlapping part is the overlapping region pattern.

[0067] The area of the overlapping region pattern is determined. If the area of the overlapping region pattern is large, specifically greater than an area threshold, the overlapping region is classified as a room with a small area, and the overlapping region pattern is determined as a new region pattern.

[0068] If the area of the overlapping region pattern is small, specifically less than or equal to the area threshold, one of the overlapping first region pattern and the second region pattern is adjusted. For example, the overlapping region pattern is deleted in the first region pattern, the area of the overlapping region pattern is included in the second region pattern, or the overlapping region pattern is deleted in the second region pattern, and the area of the overlapping region pattern is included in the first region pattern.

[0069] The embodiments of the present application can ensure the accuracy of the house type diagram by processing the overlapping region based on the area of the overlapping region.

[0070] In some embodiments of the present application, the first contour and the second contour each include at least one contour line segment;

[0071] Generating a target house type diagram according to the first contour and the second contour includes:

[0072] Receiving a configuration input of the at least one contour line segment;

[0073] In response to the configuration input, setting a line segment attribute of the at least one contour line segment to obtain the target house type diagram, wherein the line segment attribute includes one or a combination of a wall type, a door type, and a window type.

[0074] In the embodiments of the present application, after obtaining the first contour of the entire property in the house type diagram and the second contour of each room inside the property, the first contour and the second contour each include at least one contour line segment. It can be understood that the contour line segment can be a straight line segment or a curved line segment.

[0075] The user or the draftsman can configure the line segment attribute of the line segment in the first contour and the second contour through configuration input, such as configuring the wall type of a certain contour line segment, for example, configuring the wall type of the first contour line segment as a load-bearing wall. For example, marking the door type on a certain contour line segment, for example, marking the door type on the second contour line segment as a front door. For example, marking the window type on a certain contour line segment, for example, marking the window on the third contour line segment as a bay window.

[0076] The embodiment of the present application marks the wall type, the door type and the window type in the house type drawing by configuring the line segment attribute of the line segment contour line segment, and enriches the content of the house type drawing.

[0077] In some embodiments of the present application, the house type drawing to be processed is preprocessed to obtain a target image, comprising:

[0078] The house type drawing to be processed is subjected to gray scale processing to obtain a target gray scale drawing;

[0079] The target gray scale drawing is subjected to noise reduction processing to obtain a target image.

[0080] In the embodiment of the present application, the house type drawing to be processed is a house type drawing drawn by a draftsman. After obtaining the house type drawing to be processed, the house type drawing to be processed is first preprocessed. Specifically, the house type drawing to be processed is first subjected to gray scale processing, so as to remove useless information such as background color in the house type drawing, and obtain a target gray scale drawing.

[0081] In some embodiments, the target gray scale drawing can also be subjected to binaryzation processing, so as to further remove useless information such as watermarks and decorative patterns.

[0082] After obtaining the target gray scale drawing, the target gray scale drawing is further subjected to noise reduction processing to remove noise information in the image, and obtain a target image after noise reduction.

[0083] The embodiment of the present application removes useless information and noise information in the house type drawing to be processed through preprocessing, so as to improve the purity of the drawing degree after vector processing, and improve the display effect of the house type drawing.

[0084] In some embodiments of the present application, the house type drawing is subjected to vectorization processing, specifically comprising the following steps:

[0085] 1. First, obtain the house type drawing, and preprocess it (convert it into a gray scale drawing, and remove noise points) to obtain a standard house type drawing (an outer contour and a uniform size), then perform fitting and smoothing processing on the overall outer contour of the standard house type drawing, and finally perform fitting and smoothing processing on the room contour, and finally generate a vectorized house type drawing;

[0086] 2. When integrating the overall outer contour, first obtain the outline shape of the apartment, then expand it proportionally according to the outline of the internal rooms, stop when it touches the outline of another room, and finally optimize it by deleting smaller spaces. Finally, smooth and collinearize the outer contour.

[0087] 3. When optimizing and integrating room outlines, first obtain the room outlines, then smooth and cross the closed room outlines. If two rooms have a large overlapping area, the overlapping area can be assigned to the smaller room. If two rooms have a small overlapping area, the outline of one of the rooms will be offset.

[0088] 4. Finally, define the specific walls in the vector diagram, and determine which locations are doors, windows, and the type of wall.

[0089] The floor plan processing method provided in this application can be executed by a floor plan processing device. This application uses the floor plan processing device executing the floor plan processing method as an example to illustrate the floor plan processing device provided in this application.

[0090] In some embodiments of this application, a floor plan processing device is provided. Figure 4 A structural block diagram of a floor plan processing apparatus according to an embodiment of this application is shown, such as... Figure 4 As shown, the floor plan processing device 400 includes:

[0091] Preprocessing module 402 is used to preprocess the floor plan to be processed to obtain a target image. The content of the target image includes a target object, and the target object includes multiple object regions.

[0092] The determination module 404 is used to determine the first contour of the target object; it is also used to determine the second contour of multiple object regions.

[0093] The generation module 406 is used to generate a target floor plan based on the first contour and the second contour.

[0094] In this application embodiment, for scenarios such as online house viewing, users may use electronic devices such as mobile phones and tablets to display floor plans. Different electronic devices have different hardware and software; therefore, the floor plans may be compressed or enlarged to adapt to the displays of different electronic devices.

[0095] In related technologies, floor plans are drawn manually by draftsmen and saved as images after completion. Therefore, scaling the floor plan image can lead to problems such as blurry display.

[0096] To address the aforementioned issues, this application vectorizes the floor plan based on its overall outline and internal room outlines. The vectorized floor plan remains undistorted and unblurred regardless of whether it is scaled or not.

[0097] Specifically, the floor plan to be processed is the floor plan drawn by the draftsman. After obtaining the floor plan to be processed, the first step is to preprocess it. Specifically, the preprocessing steps can be to remove useless parts of the floor plan, such as decorative patterns and background colors, to obtain a relatively clean line floor plan, which is the target image.

[0098] The target image includes the target object, which is the property shown in the floor plan, such as a unit with an area of ​​100 square meters. 2 The target property includes multiple areas, which are the various rooms within the property, including the porch, entryway, living room, bedroom, and bathroom.

[0099] The first outline of the current property as a whole and the second outline of each room in the current property are drawn separately. Both the first and second outlines are drawn in vector form. In the final target floor plan, the overall outer outline and the internal room outlines are vectorized line segments or curve segments. Therefore, a vectorized floor plan can be obtained. When displaying the vectorized floor plan, no image distortion or blurring will occur, regardless of whether the floor plan is compressed or enlarged, thus improving the display effect of the floor plan.

[0100] In some embodiments of this application, the floor plan processing apparatus further includes:

[0101] The recognition module is used to recognize the outer contour of the target object and obtain multiple outer contour feature points of the target object.

[0102] The image processing module is used to fit the outer contour curve of the target object based on multiple outer contour feature points; and to smooth the outer contour curve to obtain the first contour.

[0103] In this embodiment of the application, the first outline is the overall outline of the property shown in the current floor plan. Figure 2 A schematic diagram of a first outline according to an embodiment of this application is shown, as follows. Figure 2 As shown, when drawing the first contour, image recognition is first performed on the preprocessed floor plan, that is, the target object 202 in the target image 200. Specifically, edge detection is performed on the target object, and feature points on the edge of the target object are obtained through the edge detection algorithm, which are denoted as outer contour feature points 204.

[0104] The contour feature points 204 are fitted, and a curve obtained by fitting is a contour curve 206 of the target object. It can be understood that the contour curve can be a closed curve or an open curve, and the embodiments of the present application do not limit this.

[0105] The fitted contour curve is further smoothed, and a first vectorized contour is obtained.

[0106] The embodiments of the present application vectorize the overall contour of the house type drawing, that is, the first contour. The vectorized target house type drawing processed will not be blurred and distorted when displayed at any resolution, and the display effect of the house type drawing can be improved.

[0107] In some embodiments of the present application, the generation module is further configured to generate a corresponding region graph in each object region according to the shape of each object region in the plurality of object regions, and the area of the region graph is less than the area of the object region.

[0108] The image processing module is further configured to proportionally enlarge each region graph in the plurality of region graphs until at least one side of each region graph intersects at least one side of at least one other region graph.

[0109] The determination module is further configured to determine a second contour according to the plurality of region graphs after proportional enlargement.

[0110] In the embodiments of the present application, after the house type drawing to be processed is preprocessed, a target image is obtained, the target image includes a target object, that is, a house property displayed by the house type drawing, and the target object includes a plurality of object regions, each of which corresponds to a room in the house property.

[0111] Since the shapes of the rooms can be different and irregular, a region graph is first drawn in each room, Figure 3 FIG. 2 shows a schematic diagram of a second contour according to an embodiment of the present application, as Figure 3 As shown in FIG. 2, the shape of the region graph 3022 is the same as that of the corresponding object region 302, and the area of the region graph is less than that of the object region.

[0112] Meanwhile, the region graphs 3022 are proportionally enlarged, and in the process of enlarging the region graphs 3022, adjacent region graphs approach each other. When a region graph intersects with a side of another region graph, the enlargement of the two region graphs is stopped, and each region graph is in contact with at least one other region graph.

[0113] At this time, adjacent region graphs in the plurality of region graphs drawn share a side, as Figure 3As shown, there is a common edge 308 between the first region graph 304 and the second region graph 306.

[0114] According to the edges of the enlarged region graphs, the second contour of each object region, i.e., each room, can be determined.

[0115] Embodiments of the present application draw region graphs with the same shape as the rooms, and obtain rooms matching the shape, size and position of the real rooms by inflating the region graphs, so as to accurately draw the contours of the rooms and finally generate vectorized rooms, which can avoid display distortion and blurring when the house type diagram is scaled.

[0116] In some embodiments of the present application, the determining module is further configured to determine a graph contour curve of each region graph in the plurality of region graphs.

[0117] The image processing module is further configured to perform smoothing processing on the graph contour curve to obtain the second contour.

[0118] In embodiments of the present application, after the plurality of region graphs are enlarged, a graph contour curve of each enlarged region graph is determined, which is a curve formed by the edges of the region graph. It can be understood that the graph contour curve can be a closed curve, i.e., the outer edges of the region graph form a closed shape. The graph contour curve can also be an open curve, which is not limited in embodiments of the present application.

[0119] The graph contour curve of each region graph, i.e., each room, is smoothed, and a vectorized second contour can be obtained.

[0120] Embodiments of the present application vectorize the contour of each room in the house type diagram, i.e., the second contour. The processed vectorized target house type diagram will not be blurred or distorted when displayed at any resolution, which can improve the display effect of the house type diagram.

[0121] In some embodiments of the present application, the determining module is further configured to, when the first region graph and the second region graph in the plurality of region graphs satisfy a condition that at least part of the first region graph and at least part of the second region graph coincide, determine a coinciding region graph of the first region graph and the second region graph; and when the area of the coinciding region graph is greater than an area threshold, determine the coinciding region graph as a new region graph.

[0122] The house type diagram processing apparatus further includes:

[0123] The deleting module is configured to, when the area of the coinciding region graph is less than or equal to the area threshold, delete the coinciding region graph in the first region graph or the second region graph.

[0124] In the embodiments of the present application, when the region graphs corresponding to the plurality of object regions are scaled up at a constant ratio, there can be a case where the scaled-up region graph at least partially overlaps with other region graphs. If the first region graph and the second region graph overlap, the overlapping part is the overlapping region graph.

[0125] The area of the overlapping region graph is determined. If the area of the overlapping region graph is large, specifically greater than an area threshold, the overlapping region is classified as a room with a small area, and the overlapping region graph is determined as a new region graph.

[0126] If the area of the overlapping region graph is small, specifically less than or equal to the area threshold, one of the overlapping first region graph and the second region graph is adjusted, such as deleting the overlapping region graph in the first region graph, classifying the area of the overlapping region graph into the second region graph, or deleting the overlapping region graph in the second region graph, and classifying the area of the overlapping region graph into the first region graph.

[0127] The embodiments of the present application can ensure the accuracy of the house type graph by processing the overlapping region based on the area of the overlapping region.

[0128] In some embodiments of the present application, the first contour and the second contour each include at least one contour line segment;

[0129] The house type graph processing apparatus further includes:

[0130] The receiving module is configured to receive a configuration input of the at least one contour line segment;

[0131] The setting module is configured to set a line segment attribute of the at least one contour line segment in response to the configuration input, to obtain a target house type graph, wherein the line segment attribute includes one or a combination of a wall type, a door type, and a window type.

[0132] In the embodiments of the present application, after obtaining the first contour of the entire property in the house type graph and the second contour of each room inside the property, the first contour and the second contour each include at least one contour line segment. It can be understood that the contour line segment can be a straight line segment or a curved line segment.

[0133] The user or the draftsman can configure the line segment attribute of the contour line segment in the first contour and the second contour through the configuration input, such as configuring the wall type of a certain contour line segment, for example, configuring the wall type of the first contour line segment as a load-bearing wall. For example, marking the door type on a certain contour line segment, for example, marking the door type on the second contour line segment as a front door. For example, marking the window type on a certain contour line segment, for example, marking the window on the third contour line segment as a bay window.

[0134] The embodiment of the present application marks the wall type, the door type and the window type in the house type drawing by configuring the line segment attribute of the line segment contour line segment, and enriches the content of the house type drawing.

[0135] In some embodiments of the present application, the preprocessing module is specifically configured to perform grayscale processing on the house type drawing to be processed to obtain a target grayscale drawing, and perform noise reduction processing on the target grayscale drawing to obtain a target image.

[0136] In the embodiment of the present application, the house type drawing to be processed is a house type drawing drawn by a draftsman. After obtaining the house type drawing to be processed, the house type drawing to be processed is first preprocessed. Specifically, the house type drawing to be processed is first subjected to grayscale processing, so as to remove useless information such as the background color in the house type drawing, and obtain a target grayscale drawing.
