[0008] Optionally, determining the offset parameter based on the reference information includes: obtaining an offset reference value; wherein the offset reference value is determined based on the offset reference value and / or the thickness of the outer wall of the target building; if half of the maximum depth of the inner doorway is greater than the offset reference value, then the offset parameter is determined based on half of the maximum depth of the inner doorway; if half of the maximum depth of the inner doorway is not greater than the offset reference value, then the offset reference value is used as the offset parameter.

[0009] Optionally, the step of performing an inward offset operation on the second contour based on the offset parameter to obtain the inner edge line of the outer wall of the target house includes: performing an inward offset operation on the second contour based on the offset parameter to obtain an inward offset result; and optimizing the inward offset result based on the corner of the second contour to obtain the inner edge line of the outer wall of the target house.

[0010] Optionally, the optimization process includes trimming and / or completion processing.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0022] The inventors discovered through research that the existing technology of manually selecting areas along the inner edges of exterior walls on a floor plan using specific software suffers from significant efficiency bottlenecks and accuracy deficiencies. This is especially true for complex floor plans, requiring substantial manpower and time, resulting in low efficiency in determining the inner boundary area of ​​the exterior walls. Furthermore, this manual selection method relies entirely on subjective human operation, making batch execution impossible and exhibiting poor reliability. Factors such as different handling methods for corner areas and mouse placement deviations during manual selection further complicate the process. This leads to significant discrepancies in the area of ​​the inner frame of the exterior walls determined by different individuals for the same apartment type, making it impossible to guarantee the accuracy of the final area. To improve upon these issues, this disclosure provides a method, device, medium, and program product for determining the area, which will be described in detail below.

[0023] Figure 1This is a flowchart illustrating a method for determining the area of ​​a region according to an embodiment of this disclosure. This method can be executed by a region area determining device, which can be implemented in software and / or hardware, and is generally integrated into an electronic device. Figure 1 As shown, the method mainly includes the following steps S102 to S106: Step S102: Obtain the first outline of the target house with the area to be determined; wherein, the first outline is the outline of the target area of ​​the target house, and the target area is the area of ​​the target house after removing the area occupied by the exterior walls and the area occupied by the interior walls. It can also be understood as the usable area of ​​the target house.

[0024] Any house whose inner frame area needs to be determined can be used as the target house. In practical applications, the floor plan data of the target house can be obtained first. For example, this floor plan data can be graphic data or vector data, without limitation. The floor plan data can be used to indicate the vertex coordinates, size parameters, and other parameter information of each room in the target house. Since the target area is the area of ​​the target house after removing the area occupied by the outer and inner walls, there is no need to consider the wall area. Therefore, the target area can be determined conveniently and quickly based on the floor plan data, and the accuracy of the target area can be guaranteed. Based on the determination of the target area, the outline of the target area can be directly obtained, that is, the first outline. In some examples, the first outline can be represented by vector data, such as by the endpoint coordinates of each line segment on the outline.

[0025] Step S104: Obtain offset parameters; perform an outward offset operation on the first contour based on the offset parameters to obtain the second contour, and perform an inward offset operation on the second contour based on the offset parameters to obtain the inner edge line of the outer wall of the target house; wherein, the area enclosed by the second contour includes: the area enclosed by the inner edge line of the outer wall and the area occupied by the outer wall of the target house.

[0026] Offset parameters are used to indicate the amount of contour offset. In practical applications, offset parameters can be preset parameter values ​​or parameter values ​​determined based on relevant information such as the thickness of the outer wall and the depth of the inner door opening of the target building. The specific values ​​can be flexibly set according to the actual situation.

[0027] Based on the known offset parameters, the first contour can be offset outwards to obtain the second contour. This outward offset further expands the area occupied by the inner and outer walls, ensuring the second contour encompasses the area enclosed by the inner edge of the outer wall and the area occupied by the outer walls of the target building. In some cases, the contour offset indicated by the offset parameters equals the thickness of the target building's outer walls. In this case, the second contour is the outer edge of the target building's outer walls, and the area it encloses includes the area enclosed by the inner edge of the outer walls and the area occupied by the outer walls of the target building, which is equal to the target building's total footprint. Specifically, this includes the usable areas of each room, the area occupied by the inner walls, and the area occupied by the outer walls. In other cases, the contour offset indicated by the offset parameters may be greater than the thickness of the target building's outer walls. In this case, the area enclosed by the second contour, in addition to the area enclosed by the inner edge of the outer walls and the area occupied by the outer walls of the target building, will also include the edge area outside the outer edge of the target building's outer walls. Both the outer wall area and the aforementioned edge area belong to the area outside the inner edge of the outer walls. Since the area occupied by the inner wall has been covered by the outward offset operation, the internal area enclosed by the inner edge of the outer wall has been completely merged into a whole. Based on this, the inward offset operation performed on the second contour will not affect the area enclosed by the inner edge of the outer wall, but will only affect the area outside the inner edge of the outer wall, such as removing the area occupied by the outer wall and other areas outside the inner edge of the outer wall, thus cleverly obtaining the inner edge of the outer wall.

[0028] Step S106: Determine the area enclosed by the inner edge line of the target building's outer walls. The area enclosed by the inner edge line of the target building's outer walls can also be referred to as the area of ​​the inner frame of the outer walls.

[0029] The area enclosed by the inner edge of the outer wall is a polygon. For example, the area enclosed by the inner edge of the outer wall can be determined by a geometric algorithm. In some specific examples, the area can be calculated by the shoelace formula (also known as the Gaussian area formula) or by calling library functions in the geometric calculation library. The entire calculation process is completed automatically by the computer program, which takes very little time and can have high accuracy.

[0030] In summary, the area determination method provided in this embodiment can first obtain the outline of the target area, and then perform outward offset and inward offset operations sequentially. The outward offset operation can further cover the area occupied by the inner wall and the area occupied by the outer wall on the basis of the target area, and the inward offset operation can eliminate the area occupied by the outer wall, thereby cleverly obtaining the inner edge line of the outer wall, and then obtaining the area enclosed by the inner edge line of the outer wall. The above method does not require manual selection of the area along the inner edge line of the outer wall on the floor plan, and can efficiently and quickly obtain the inner edge line of the outer wall, greatly saving the cost required to determine the area of ​​the inner frame of the outer wall, effectively improving the efficiency of area determination, and has strong reliability.

[0031] In some implementations, step S102, which is the step of obtaining the first outline of the target house with the area to be determined, can be performed as follows: steps (1) to (3): Step (1): Obtain the floor plan data of the target house whose area needs to be determined. For example, the floor plan data is vector data containing information such as the vertex coordinates and size parameters of each room of the target house.

[0032] Step (2): Based on the house type data, obtain the usage area of ​​each independent room in the target house and the area occupied by each internal doorway in the target house.

[0033] For example, based on the floor plan data, the outlines of each individual room in the target house and the outlines of each internal doorway in the target house can be obtained. The outline of an individual room is the outline formed by the inner edges of the walls of the individual room, also known as the net outline line. The outline of an internal doorway is the outline formed by the edges of the internal doorway. In some examples, the floor plan data is vector data, and each of the above outlines is a polygon, which can be represented by a series of ordered vertex coordinates. For example, the outline of a room can be represented as... ,in This represents the coordinates of the i-th vertex of the room. The area enclosed by the outline of the independent room is the usable area of ​​the independent room, and the area enclosed by the outlines of each inner doorway is the occupied area of ​​the inner doorway. The boundaries of each of these areas can be accurately determined using the outlines.

[0034] Step (3) merges the usage areas of all independent rooms and the footprints of all internal doorways to obtain the target area of ​​the target house. An internal doorway is a doorway on an interior wall that connects at least two room areas.

[0035] For example, the usable areas of all independent rooms and the occupied areas of all internal doorways can be merged based on a geometric merging algorithm to obtain a continuous polygon. This embodiment of the disclosure does not limit the above geometric merging algorithm. In practical applications, the above-mentioned merging process can be achieved by directly using existing software tools for processing spatial geographic data, merging operations in computational geometry libraries, etc., to obtain the target area. The target area is usually a polygon, specifically the usable area of ​​the target house, which can also be called the interior area.

[0036] Step (4): Obtain the first contour of the target area. The contour formed by the edge lines of the target area is the first contour. The first contour can also be understood as the contour enclosed by the inner edge of the outer wall, the outer edge of the inner wall, and the edge of the inner doorway of the target building. For easier understanding, please refer to... Figure 2 The diagram shown illustrates a housing information processing result. In this diagram, the green lines represent the inner wall boundaries of individual rooms, and the area enclosed by the green lines is the usable area of ​​the individual room. The red lines represent the edge of the inner doorway, and the area enclosed by the red lines is the footprint of the inner doorway. It should be noted that... Figure 2 The image also illustrates other colors, such as the blue line representing the edge of the window opening. Since these are embedded in the wall, they don't need to be considered here; in this example, only the red and green lines need to be considered. Figure 2 In the middle, the individual rooms are merged through internal doorways to form a connected and complex target area. That is, the target area is the complex area after all the green-filled areas are merged, and the edge line of the complex area is the first outline.

[0037] By merging the usable areas of each independent room in the target house with the area occupied by the interior doorway, the discrete usable areas in the target house can be aggregated into a unified usable area or interior area. This efficiently and quickly yields the target area (i.e., the area of ​​the target house after removing the areas occupied by the exterior and interior walls), which serves as the reference geometry for subsequent calculations. This provides the data basis for automatically determining the area of ​​the interior frame of the exterior walls, effectively avoiding the tedious process of processing each room individually and significantly improving processing efficiency.

[0038] In some implementations, the step of obtaining the offset parameter in step S104 above can be performed as follows: steps a to b: Step a, obtain reference information; wherein, the reference information includes at least one of the following: the maximum depth of the inner doorway of the target house, the thickness of the outer wall of the target house, and a preset offset reference value. The inner doorway is used to connect at least two room areas, and the depth of the inner doorway is the thickness of the inner wall corresponding to the inner doorway; in some scenarios, it can also be directly referred to as the inner doorway thickness. Considering that the target house may contain multiple inner doorways, and the depths of these inner doorways may be the same or different, the maximum depth of the inner doorway is selected as the reference information. In practical applications, the maximum depth of the inner doorway and the thickness of the outer wall can both be obtained based on measurement. The preset offset reference value can be determined in advance based on one or more of the following: statistically obtained wall information of multiple houses, empirical values ​​obtained from the results of contour offset operations performed on multiple houses, etc. The above are only examples; other factors can also be considered in practical applications, which will not be listed here one by one. This embodiment of the disclosure does not limit the offset reference value, such as 240mm.

[0039] Step b: Determine the offset parameter based on the reference information. In some examples, the reference information contains only one type of data. In such cases, the offset parameter only needs to be determined based on the value of that data type. For instance, if the reference information only contains an offset reference value, the offset reference value is directly used as the offset parameter. If the reference information only contains the maximum value of the inner doorway depth, half of the maximum inner doorway depth can be used as the offset parameter, or the result obtained by adding a floating value to half of the maximum inner doorway depth can be used as the offset parameter. In other examples, the reference information contains multiple types of data. In these cases, the data values ​​of each of the multiple data types can be fused or analyzed to determine a suitable offset parameter. This method effectively ensures the rationality of the offset parameter. In some specific examples, step b can be performed as follows: Steps b1 to b3. Step b1, obtain the offset reference value; wherein the offset reference value is determined based on the offset reference value and / or the thickness of the exterior walls of the target building. For example, the offset reference value is the offset reference value or the thickness of the exterior walls, or the offset reference value is a weighted fusion value of the offset reference value and the thickness of the exterior walls.

[0040] Step b2: If half of the maximum depth of the inner doorway is greater than the offset reference value, then the offset parameter is determined based on half of the maximum depth of the inner doorway.

[0041] For example, assuming the offset baseline is 240mm and the maximum depth of the inner doorway is 500mm, half of the maximum depth of the inner doorway, 250mm, can be directly used as the offset parameter, or a small floating value can be added to 250mm as the offset parameter. As mentioned earlier, the offset parameter is used to indicate the contour offset. The purpose of the outward offset operation performed according to the offset parameter is to cover the area occupied by the inner wall, so that the internal area enclosed by the inner edge of the outer wall is completely merged into a whole. The inner doorway is used to connect two room areas sharing the same inner wall, and the depth of the inner doorway is equal to the thickness of the inner wall. Figure 2 It is known that the outline of an independent room is enclosed by the inner edge of its walls, and the outlines of each independent room are also components of the first outline to be offset outwards, all of which need to be offset outwards. If the inner edge of the walls of the two rooms corresponding to the inner doorway is offset outwards by half the depth of the inner doorway, then the area occupied by the inner wall between these two rooms will be covered. In the case of multiple inner doorways, if half of the maximum depth of the inner doorway is used as the offset parameter, then the inner edge of the walls of the two rooms corresponding to all the inner doorways in the target house will be offset by half of the maximum depth of the inner doorway, ensuring that all the area occupied by the inner wall in the target house is covered, thereby merging the multiple discrete room areas separated by the inner walls inside the target house into a whole. It should be noted that for inner doorways with smaller depths, the outward offset operation performed using the above offset parameters may cause partial overlap between the two room areas, but this will not affect the overall result, because the purpose of the outward offset operation is to merge the discrete room areas inside the target house into a whole, and even if there is some overlap, it will not affect the definition of the usable area of ​​the target house.

[0042] Step b3: If half of the maximum depth of the inner doorway is not greater than the offset reference value, then the offset reference value is used as the offset parameter. Based on the preceding analysis, if half of the maximum depth of the inner doorway is not greater than the offset reference value, then performing an outward offset operation according to the offset reference value can completely cover the area occupied by the inner walls of the target house, making the internal area enclosed by the inner edge of the outer walls a complete whole. Therefore, the offset reference value can be directly used as the offset parameter. By using the method described in steps b1 to b3, which comprehensively considers the maximum depth of the inner doorway and the offset reference value, the accuracy and rationality of the final offset parameter can be effectively guaranteed.

[0043] Based on the obtained offset parameters, an outward offset operation is performed on the first contour to obtain the second contour. For easier understanding, please refer to [link to relevant documentation]. Figure 3The diagram shown illustrates a housing information processing result, using the simplest housing structure as an example. It includes two rooms and an internal doorway between them. The internal doorway is located in the shared internal wall between room 1 and room 2. Figure 3 The left-hand diagram illustrates that the usable areas of Room 1 and Room 2, along with the area occupied by the inner doorway, are combined into the target area, all filled with light gray. The outline surrounding the target area is the first outline, which is formed by... Figure 3 The black lines on the left side of the image represent the contour. Based on the offset parameters, an outward offset operation is performed on the first contour, as shown below. Figure 3 As shown, each black line in the left-hand image is offset along its respective outward-pointing arrow. The final outward offset result can be found in [reference needed]. Figure 3 The right-hand diagram shows the outer contour (dashed outline) of the dark gray filled area, which is the second contour. This dark gray filled area includes the target area, as well as the areas occupied by the exterior and interior walls. It can also be described as the area enclosed by the second contour, encompassing both the area enclosed by the inner edge of the exterior walls and the area occupied by the exterior walls. By determining reasonable offset parameters as described above, the outward offset result can completely cover the area occupied by the interior walls, thus connecting the wall areas, discrete room usage areas, and interior doorway areas into a unified whole, which can be considered as the entire area occupied by the target building. Figure 3 This is merely a simple example; in real-world applications, houses are often much more complex. Based on the above operations, this disclosure also provides embodiments such as... Figure 4 The diagram shown illustrates the result of housing information processing. Figure 2 Based on the result of the outward offset operation, Figure 4 exist Figure 2 Based on this, in addition to the usage areas of each discrete room and the area occupied by the inner doorway, the area occupied by the inner wall and the area occupied by the outer wall are completely covered by the outward offset operation, thus obtaining a whole area.

[0044] In some implementations, the step S104 above, which involves performing an inward offset operation on the second contour based on the offset parameter to obtain the inner edge line of the outer wall of the target building, can be performed as follows: Steps A and B: Step A: Perform an inward offset operation on the second contour based on the offset parameters to obtain the inward offset result. As mentioned earlier, the purpose of the inward offset operation is to eliminate the area occupied by the outer wall, thereby obtaining the inner edge line of the outer wall. Based on the second contour obtained through the outward offset operation, the area enclosed by the second contour is shrunk inward by the same distance through the inward offset operation, thereby accurately eliminating the area occupied by the outer wall introduced by the outward offset operation.

[0045] Step B involves optimizing the inward offset result based on the corners of the second contour to obtain the inner edge line of the target building's exterior wall. It is understood that the second contour is typically a polygonal contour containing multiple corners, including convex and concave corners. The optimization process includes trimming and / or completion processing. Different corner types require different optimization processing methods. In practical applications, corresponding optimization operations can be performed on each corner of the second contour separately to ensure the reliability of the final inner edge line of the exterior wall.

[0046] Based on the optimization process, which includes cropping and / or completion, in some specific implementation examples, step B above can be performed as follows: Steps B1 to B3: Step B1: If the corner of the second contour includes a convex corner, then the excess portion in the inward offset result is determined based on the convex corner, and the excess portion in the inward offset result is trimmed. For easier understanding, please refer to... Figure 5 The diagram shown illustrates a corner treatment. Figure 5 The illustration shows a house layout with multiple corners, and simply marks one convex corner and one concave corner. For the convex corner, the two sides of the convex corner will intersect when they are offset inward, resulting in an extra part. Therefore, the extra part can be directly cut off to obtain a standard corner.

[0047] Step B2: If the corner of the second contour includes a concave corner, then determine the missing portion in the inward offset result based on the concave corner, and complete the missing portion in the inward offset result. See also... Figure 5 For concave corners, missing sections appear when the two sides of the concave corner are offset inward. These missing sections need to be filled in to ensure that the final inner edge line of the outer wall obtained by the inward offset is complete and continuous. In practical applications, the two endpoints of the missing sections can be connected with lines, such as smooth curves, to obtain a smooth corner.

[0048] For example, the missing parts in the inward offset result are filled in by: determining a set of endpoints to be processed based on the missing parts in the inward offset result; wherein the set of endpoints includes a first line endpoint and a second line endpoint, and the set of endpoints has a one-to-one correspondence with the concave angle of the second contour; and performing curve connection processing on the first line endpoint and the second line endpoint in the set of endpoints. See also Figure 5 The first and second line endpoints in the endpoint group form a concave angle before the inward offset operation, but are moved away from each other due to the inward offset operation. A smooth corner is obtained by connecting the curves.

[0049] Step B3: Based on the optimized inward offset result, obtain the inner edge line of the outer wall of the target house.

[0050] By using steps B1 to B3 above, the cornering issue in the inward offset result can be optimized, thus obtaining a continuous inner edge line of the outer wall. For easier understanding, please refer to... Figure 6 The diagram shown illustrates the result of housing information processing. Figure 5 Based on this, the area occupied by the outer wall is removed by offsetting inward, and the remaining area is the area surrounded by the inner edge of the outer wall of the house. Figure 6 For illustrative purposes only, this apartment layout only includes protruding corners. Figure 6 This illustration shows the final result after trimming the convex corner. Further details can be found in [link to relevant documentation]. Figure 7 The diagram shown illustrates the result of housing information processing. Figure 4 Based on this, the area occupied by the outer wall is eliminated by offsetting inward, ultimately obtaining the area enclosed by the inner edge of the outer wall, that is... Figure 7 All green-filled areas in the middle, among which, Figure 7 The corners in the image are all obtained after the above optimization process, making them smoother and more regular.

[0051] For ease of understanding, see [link to relevant documentation]. Figure 8 The flowchart shown is a method for determining the area of ​​a region, which mainly includes the following steps S802 to S816: Step S802: Obtain the floor plan data of the target house in the area to be determined.

[0052] Step S804: Based on the floor plan data, obtain the outlines of each independent room in the target house and the outlines of each interior doorway in the target house.

[0053] Step S806: Merge the outlines of all individual rooms and all interior doorways to obtain the first outline of the target house.

[0054] Step S808: Obtain reference information; wherein the reference information includes at least one of the following: the maximum depth of the inner doorway of the target house, the thickness of the outer wall of the target house, and a preset offset reference value.

[0055] Step S810: Determine the offset parameters based on the reference information.

[0056] Step S812: Perform an outward offset operation on the first contour based on the offset parameters to obtain the second contour. The area enclosed by the second contour includes the area enclosed by the inner edge of the outer wall of the target building and the area occupied by the outer wall of the target building. This operation can also be referred to as forward buffering operation.

[0057] Step S814: Perform an inward offset operation on the second contour based on the offset parameters to obtain the inner edge line of the outer wall of the target building. This operation can also be referred to as a reverse buffering operation.

[0058] Step S816: Determine the area enclosed by the inner edge of the outer wall of the target house.

[0059] The specific implementation methods for the above steps can be found in the aforementioned related content and will not be repeated here. The above method accurately determines the inner edge line of the outer wall by sequentially performing discrete region merging, forward offset, and reverse offset operations. Based on this, the inner frame area of ​​the outer wall can be determined efficiently and conveniently, eliminating the need for manual selection along the inner edge line on the floor plan. This significantly reduces the cost of determining the area of ​​the inner frame, effectively improving the efficiency of area determination and providing strong reliability. Furthermore, in the inward offset operation, the corners of the second contour can be optimized specifically according to concave and convex corner types, making the corners of the final inner edge line of the outer wall more regular, resulting in a smooth and accurate inner edge line, further improving the accuracy of the inner frame area. Moreover, the above operations have a unified standardized process, entirely executed by computer programs, effectively eliminating subjective biases and mouse-point errors caused by manual operation, fully guaranteeing area accuracy. The above method can be well applied to various apartment layouts, even complex layouts, and can efficiently and quickly obtain high-precision inner frame areas of the outer walls.

[0060] It should also be noted that the area determination method provided in this embodiment can be entirely based on vector floor plan data. The contours and areas involved can be directly represented by key point coordinates, without the need to obtain a planar floor plan image. Figures 2-7 All of these are intuitive and visual representations of the converted data for ease of understanding. Compared to image processing methods, the methods provided in this disclosure effectively reduce processing costs and computational load, significantly improving processing efficiency. Furthermore, for complex floor plans, directly extracting the inner edges of exterior walls from corresponding floor plan images using computer programs is difficult and inaccurate. In contrast, the methods provided in this disclosure can achieve high-precision results through data computation at a lower cost, exhibiting greater reliability and universality.

[0061] Corresponding to the aforementioned method for determining the area, this disclosure further provides a device for determining the area. Figure 9 This is a schematic diagram of a region area determination device provided in an embodiment of the present disclosure. The device can be implemented by software and / or hardware, and is generally integrated into an electronic device, such as... Figure 9 As shown, the area determination device includes: The first contour acquisition module 902 is used to acquire the first contour of the target house with the area to be determined; wherein, the first contour is the contour of the target area of ​​the target house, and the target area is the area of ​​the target house after removing the area occupied by the exterior walls and the area occupied by the interior walls. The offset operation module 904 is used to obtain offset parameters; perform an outward offset operation on the first contour based on the offset parameters to obtain a second contour; and perform an inward offset operation on the second contour based on the offset parameters to obtain the inner edge line of the outer wall of the target house; wherein, the area enclosed by the second contour includes: the area enclosed by the inner edge line of the outer wall of the target house and the area occupied by the outer wall of the target house. The area determination module 906 is used to determine the area of ​​the region enclosed by the inner edge line of the outer wall of the target house based on the inner edge line of the outer wall of the target house.

[0062] The aforementioned device can first obtain the outline of the target area, and then perform outward offset and inward offset operations sequentially. The outward offset operation can further cover the area occupied by the inner wall and the area occupied by the outer wall on the basis of the target area, and the inward offset operation can eliminate the area occupied by the outer wall, thus cleverly obtaining the inner edge line of the outer wall, and then obtaining the area enclosed by the inner edge line of the outer wall. The aforementioned device does not require manual selection of the area along the inner edge line of the outer wall on the floor plan, and can efficiently and quickly obtain the inner edge line of the outer wall, greatly saving the cost required to determine the area of ​​the inner frame of the outer wall, effectively improving the efficiency of area determination, and has strong reliability.

[0063] In some implementations, the first contour acquisition module 902 is specifically used for: acquiring the floor plan data of the target house with an area to be determined; based on the floor plan data, acquiring the usage area of ​​each independent room in the target house and the footprint of each inner doorway in the target house; merging the usage areas of all the independent rooms and the footprints of all the inner doorways to obtain the target area of ​​the target house; and acquiring the first contour of the target area.

[0065] In some embodiments, the offset operation module 904 is specifically used to: obtain an offset reference value; wherein the offset reference value is determined based on the offset reference value and / or the thickness of the outer wall of the target house; if half of the maximum depth of the inner doorway is greater than the offset reference value, then an offset parameter is determined based on half of the maximum depth of the inner doorway; if half of the maximum depth of the inner doorway is not greater than the offset reference value, then the offset reference value is used as the offset parameter.

[0066] In some embodiments, the offset operation module 904 is specifically used to: perform an inward offset operation on the second contour based on the offset parameters to obtain an inward offset result; and optimize the inward offset result based on the turning angle of the second contour to obtain the inner edge line of the outer wall of the target house.

[0067] In some embodiments, the optimization process includes trimming and / or completion processing. The offset operation module 904 is specifically used to: if the corner of the second contour contains a convex corner, determine the redundant part in the inward offset result based on the convex corner, and trim the redundant part in the inward offset result; if the corner of the second contour contains a concave corner, determine the missing part in the inward offset result based on the concave corner, and complete the missing part in the inward offset result; and obtain the inner edge line of the outer wall of the target house based on the inward offset result after the optimization process.

[0068] In some embodiments, the offset operation module 904 is specifically used to: determine the endpoint group to be processed based on the missing part in the inward offset result; wherein, the endpoint group includes a first line endpoint and a second line endpoint, and the endpoint group has a one-to-one correspondence with the concave angle of the second contour; and perform curve connection processing on the first line endpoint and the second line endpoint in the endpoint group.
