[0034] Currently, the properties of wall objects include inner walls and outer walls. An inner wall refers to a wall that spans two rooms at the same time (both rooms are special rooms or both are general rooms). An outer wall refers to a wall that spans only one room or spans two rooms at the same time (one of the two rooms is a special room and the other is a general room).

Special rooms refer to specific rooms, such as room names: "Exhaust shaft", "Non-walkable roof", "Walkable roof", "Roof", "Message room", "Supply air shaft", "Fresh air shaft", "Air intake shaft", "Supply air shaft", "Bay window", "Corridor", "Terrace", "Enclosed balcony", "Open balcony", "Equipment platform", "Air conditioning position", "Outdoor platform", "Awning", "Flower bed", "Light well", "Fire corridor", "External corridor", "Eaves corridor", "Porch", "Passageway", "Outdoor bridge", "Outdoor stairs", "Outdoor fire-fighting special steel stairs", "Courtyard", and "Mezzanine".

[0036] General rooms are rooms other than special rooms.

[0037] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Figure 1 The present invention is a system block diagram of a method and device for marking walls of a building model according to an exemplary embodiment.

[0039] In the system 100 of the method and device for marking the wall of a building model, the server 105 may be a server that provides various services, such as a background management server (only for example) that provides support for the wall marking system of the building model operated by the user using the terminal devices 101, 102, and 103 through the network 104. The background management server may analyze and process the received data such as the wall marking request of the building model, and feed back the processing result (such as the wall marking result - only for example) to the terminal device.

[0040] The server 105 may be a physical server, or may be composed of a plurality of servers, a part of the server 105 may be used as a wall annotation task submission system of the building model in the present disclosure, for obtaining a task to execute a wall annotation command of the building model; and a part of the server 105 may also be used as a wall annotation system of the building model in the present disclosure, for determining a target wall object in the building model, wherein the target wall object has a first direction, and the building model has a target space range, and the target space range includes at least one room space; determining a target wall point in the target wall object; translating the target wall point in a second direction by a target translation amount to obtain a first translation point, wherein the target translation amount is the thickness of the target wall object, and the second direction is perpendicular to the first direction; translating the target wall point in a third direction by the target translation amount to obtain a second translation point, wherein the third direction is perpendicular to the first direction, and the second direction is opposite to the third direction; determining the annotation result of the target wall object according to the positional relationship between the first translation point and the second translation point in at least one room space within the target space range.

[0041] Figure 2 1 is a flowchart of a method for labeling a wall of a building model according to an exemplary embodiment. The method for labeling a wall of a building model provided in the embodiment of the present disclosure can be executed by any electronic device with computing and processing capabilities, such as terminal devices 101, 102, 103 and / or server 105. In the following embodiments, the method is illustrated by taking the server executing the method as an example, but the present disclosure is not limited thereto. The method for labeling a wall of a building model provided in the embodiment of the present disclosure can include steps S202 to S210.

[0042] like Figure 2 As shown, in step S202, a target wall object in the building model is determined, the target wall object has a first direction, the building model has a target space range, and the target space range includes at least one room space.

[0043] In the disclosed embodiment, the building model is generated by Revit software, for example. The first direction of the target wall object is the direction of the straight line where the target wall object is located. The target space range of the building model refers to the space area surrounded by the outer contour of the building model. The room space refers to the space area occupied by each room object in the building model.

[0044] In step S204, a target wall point is determined in the target wall object.

[0045] In the embodiment of the present disclosure, for example, a target wall point is determined on the wall positioning line where the target wall object is located. The target wall point may be one or more. When the target wall point is one, the center point of the wall positioning line of the target wall object may be determined as the target wall point.

[0046] In step S206, the target wall point is translated in the second direction by a target translation amount to obtain a first translation point, the target translation amount is the thickness of the target wall object, and the second direction is perpendicular to the first direction.

[0047] In the disclosed embodiment, if there is one target wall point, one first translation point can be obtained. If there are multiple target wall points, at least one first translation point corresponding to the target wall point one by one or less than the number of target wall points can be obtained.

[0048] In step S208, the target wall point is translated in a third direction by a target translation amount to obtain a second translation point, wherein the third direction is perpendicular to the first direction, and the second direction and the third direction are opposite.

[0049] In the disclosed embodiment, if there is one target wall point, one second translation point can be obtained. If there are multiple target wall points, at least one second translation point corresponding to the target wall point one by one or less than the number of target wall points can be obtained.

[0050] In step S210, a labeling result of a target wall object is determined according to a positional relationship between a first translation point and a second translation point in at least one room space within a target space range.

[0051] In the embodiment of the present disclosure, the labeling result of the target wall object can be determined according to the number and type of rooms in the room space where all the first translation points and the second translation points are located. The labeling result is that the target wall object is an interior wall or the target wall object is an exterior wall.

[0052] According to the wall labeling method of the building model provided by the embodiment of the present disclosure, a target wall point is determined in the target wall object in the building model; the target wall point is translated in a second direction and a third direction respectively perpendicular to the first direction of the target wall object to obtain a first translation point and a second translation point, and then the labeling result of the target wall object can be determined according to the positional relationship between the first translation point and the second translation point in at least one room space within the target space range, thereby realizing automatic labeling of the wall objects in the building model with high labeling accuracy.

[0053] Figure 3 The flowchart of a method for labeling a wall of a building model according to another exemplary embodiment is shown. The method for labeling a wall of a building model provided by the embodiment of the present disclosure may include steps S302 to S306.

[0054] like Figure 3 As shown, in step S302, the first room space where the first translation point is located within the target space range is determined.

[0055] In the disclosed embodiment, the first room space where the first translation point is located within the target space range refers to the room space to which the position of the first translation point within the target space range belongs. If there are multiple first translation points, the room spaces where the multiple first translation points are located within the target space range are counted to obtain at least one first room space.

[0056] In step S304, a second room space where the second translation point is located within the target space range is determined.

[0057] In the disclosed embodiment, the second room space where the second translation point is located within the target space range refers to the room space to which the position of the second translation point within the target space range belongs. If there are multiple second translation points, the room spaces where the multiple second translation points are located within the target space range are counted to obtain at least one second room space.

[0058] In step S306, the labeling result of the target wall object is determined according to the room type of the first room space and the room type of the second room space.

[0059] Figure 4 FIG. 1 is a flow chart of a method for marking walls of a building model according to another exemplary embodiment. Figure 3 Step S306 of the embodiment may further include steps S402 to S410.

[0060] like Figure 4 As shown, in step S402, the number of spaces of the first room space and the second room space is integrated to obtain the target number of rooms.

[0061] In the disclosed embodiment, the first room space and the second room space may be integrated into a set, and the number of elements in the set may be counted to obtain the target number of rooms.

[0062] In step S404, the room types of the first room space and the second room space are integrated to obtain the number of room types.

[0063] In the disclosed embodiment, the first room space and the second room space may be integrated into a set, and the number of room types of each element (ie, room space) in the set may be counted to obtain the number of room types.

[0064] In step S406, if the target room number is 1, it is determined that the target wall object is an exterior wall.

[0065] In the disclosed embodiment, if the number of target rooms is 1, it can be determined that the target wall object only spans one room, and it can be determined that the target wall object is an exterior wall.

[0066] In step S408, if the number of target rooms is 2 and the number of room types is 2, it is determined that the target wall object is an exterior wall.

[0067] In the disclosed embodiment, if the number of target rooms is 2, it can be determined that the target wall object spans 2 rooms at the same time, and if the number of room types is 2, it can be determined that of the 2 rooms spanned by the target wall object, one is a special room and the other is a general room, and it can be determined that the target wall object is an exterior wall.

[0068] In step S410, if the number of target rooms is 2 and the number of room types is 1, it is determined that the target wall object is an interior wall.

[0069] In the disclosed embodiment, if the number of target rooms is 2, it can be determined that the target wall object spans 2 rooms at the same time, and if the number of room types is 1, it can be determined that the 2 rooms spanned by the target wall object are both special rooms or both general rooms, and therefore it can be determined that the target wall object is an inner wall.

[0070] According to the wall labeling method of the building model provided by the embodiment of the present disclosure, the first room space and the second room space are integrated to obtain the target number of rooms and the number of room types, and the number of rooms and room types spanned by the target wall object can be determined based on the target number of rooms and the number of room types, and then the target wall object can be determined as an inner wall or an outer wall based on the definition of the wall object attributes, thereby realizing automatic and accurate labeling of the target wall object.

[0071] Figure 5 The flowchart of a method for labeling a wall of a building model according to another exemplary embodiment is shown. The method for labeling a wall of a building model provided by the embodiment of the present disclosure may include steps S502 to S510.

[0072] like Figure 5 As shown, in step S502, a target wall object in the building model is determined, the target wall object has a first direction, the building model has a target space range, and the target space range includes at least one room space.

[0073] In step S504, K target wall points are determined on the wall positioning line in the target wall object, where K is an integer greater than 0.

[0074] In the embodiment of the present disclosure, K target wall points can be obtained by sampling according to a preset step value on the wall positioning line of the target wall object, starting from the starting point of the wall positioning line. For another example, K points can be randomly selected on the wall positioning line as the K target wall points.

[0075] In step S506, if the 1st to k-1th first translation points are all located outside at least one room space within the target space range, the kth target wall point is translated in the second direction by the target translation amount to obtain the kth first translation point, where k is an integer greater than 1 and less than or equal to K.

[0076] In the disclosed embodiment, the first target wall point may be first translated in the second direction by the target translation amount to obtain the first first translation point. If the judgment result of "Is the first first translation point outside at least one room space within the target space range?" is yes, the second target wall point is translated in the second direction by the target translation amount to obtain the second first translation point.

[0077] For another example, when at least one of the first translation points from the first to the second (i.e., k-1, k=3) first translation points is located in at least one room space within the target space range, the translation operation of the third, fourth, ..., Kth target wall point to the second direction by the target translation amount is canceled. This method can avoid unnecessary translation operations and reduce the amount of translation calculation.

[0078] In step S508, if the 1st to k-1th second translation points are all located outside at least one room space within the target space range, the kth target wall point is translated in the third direction by the target translation amount to obtain the kth second translation point.

[0079] In the disclosed embodiment, the first target wall point may be first translated in the third direction by the target translation amount to obtain the first second translation point. If the judgment result of "Is the first second translation point located outside at least one room space within the target space range?" is yes, the second target wall point may be translated in the third direction by the target translation amount to obtain the second second translation point.

[0080] For another example, when at least one of the first to second (i.e., k-1, k=3) second translation points is located in at least one room space within the target space range, the translation operation of the third, fourth, ..., Kth target wall point to the third direction by the target translation amount is canceled. This method can avoid unnecessary translation operations and reduce the amount of translation calculation.

[0081] In step S510, a labeling result of a target wall object is determined according to a positional relationship between a first translation point and a second translation point in at least one room space within a target space range.

[0082] In this embodiment, since the specific first room space adjacent to the target wall point in the second direction can be determined based on the 1st to kth first translation points, there is no need to perform redundant judgment on the adjacent room space of the target wall point in the second direction, which can avoid unnecessary translation operations, reduce the amount of translation calculation while ensuring the accuracy of wall marking. Step S508 when performing a translation operation in the third direction to obtain the second translation point can also achieve the above technical effect.

[0083] Figure 6 The present invention is a flowchart of a method for marking walls of a building model according to yet another exemplary embodiment. Figure 2 Step S206 of the embodiment may further include steps S602 to S604.

[0084] like Figure 6 As shown, in step S602, if the first translation point is not within at least one room space within the target space range, and the first translation point is within the range of a first wall object, the thickness of the first wall object is determined.

[0085] In the disclosed embodiment, if the first translation point is not within at least one room space within the target space range, and the first translation point is within the range of a first wall object, it can be determined that the first translation point obtained after the translation of the target wall point is still located inside the wall, that is, the area outside the wall is still a wall.

[0086] In step S604, the first translation point is translated in the second direction by a first translation amount, and the translated point is used as the updated first translation point. The first translation amount is the thickness of the first wall object.

[0087] In the case where the wall outside is still a wall, it is impossible to accurately determine whether the first wall is adjacent to a room space in the second direction. In this step, the first translation point can be translated again by the first translation amount to serve as the updated first translation point. Furthermore, if the updated first translation point is within the range of the second wall object, the updated first translation point can be translated again by the second translation amount to serve as the updated first translation point, and the second translation amount is the thickness of the second wall object. The above translation operation is stopped until it is determined that the first translation point is located in at least one room space within the target space range, or the first translation point is located outside the target space range.

[0088] In an exemplary embodiment, if the fourth direction of the first wall object is perpendicular to the first direction, it is determined that the first translation point is not in at least one room space within the target space. In this embodiment, when the first direction is perpendicular to the fourth direction, it can be confirmed that the first wall object and the target wall object are in a vertical position relationship. In this case, it can be confirmed that there is no need to translate the first translation point again in the second direction, even if the room space where the updated first translation point is located after multiple translations may not be adjacent to the target wall object. Therefore, it can be directly considered that the first translation point is not in at least one room space within the target space, avoiding subsequent statistics of the room space where the first translation point is located.

[0089] Exemplarily, when translating the target wall point in a third direction by a target translation amount to obtain a second translation point, it may include: if the second translation point is not in at least one room space within the target space range, and the second translation point is within the range of a first wall object, determining the thickness of the first wall object; translating the second translation point in the third direction by a first translation amount, and using the translated point as an updated second translation point, and the first translation amount is the thickness of the first wall object.

[0090] When translating the target wall point in a third direction by a target translation amount to obtain a second translation point, the method may further include: if a fourth direction of the first wall object is perpendicular to the first direction, determining that the second translation point is not in at least one room space within the target space range.

[0091] Figure 7 FIG. 1 is a flow chart of a method for marking walls of a building model according to another exemplary embodiment. Figure 7 As shown, the wall marking method of the building model provided by the embodiment of the present disclosure may include steps S702 to S732.

[0092] In step S702, K target wall points are determined according to the direction of the wall positioning line or the room dividing line of the current wall object.

[0093] In step S704, a loop operation is performed on the kth target wall point, which loop operation includes a first loop operation of steps S706 to S716 and a second loop operation of steps S718 to S719.

[0094] The first cycle operates as follows:

[0095] In step S706, if k>1, it is determined whether to translate the kth target wall point in the second direction to obtain the kth first translation point. The determination condition can be expressed as a first determination condition: the first to k-1th first translation points are all located outside at least one room space within the target space range.

[0096] In step S708, it is determined whether the kth first translation point is in at least one room space within the target space range. If yes, step S710 is executed, otherwise, step S712 is executed.

[0097] In step S710, it is determined that the first judgment condition is not satisfied, that is, in the subsequent first loop operation, the k+1th to Kth target wall points are no longer translated in the second direction.

[0098] In step S712, it is determined whether the kth first translation point is within the range of a first wall object. If yes, step S714 is executed, otherwise, step S716 is executed.

[0099] In step S714, the first translation point is translated in a second direction by a first translation amount, and the translated point is used as an updated first translation point, and then the process returns to step S708.

[0100] In step S716, the operation of translating the kth first translation point in the second direction is ended, k is incremented by 1, and then the process returns to step S706, and step S718 is executed when k>K.

[0101] The second loop operates as follows:

[0102] In step S718, if k>1, it is determined whether to translate the kth target wall point in the third direction to obtain the kth second translation point. The determination condition can be expressed as a second determination condition: the first to k-1th second translation points are all located outside at least one room space within the target space range.

[0103] In step S720, it is determined whether the kth second translation point is in at least one room space within the target space range. If yes, step S722 is executed, otherwise, step S724 is executed.

[0104] In step S722, it is determined that the second judgment condition is not satisfied, that is, in the subsequent second loop operation, the k+1th to Kth target wall points are no longer translated in the third direction.

[0105] In step S724, it is determined whether the kth second translation point is within the range of a first wall object. If yes, step S726 is executed, otherwise, step S728 is executed.

[0106] In step S726, the second translation point is translated in the third direction by the first translation amount, and the translated point is used as the updated second translation point, and then the process returns to step S720.

[0107] In step S728, the operation of translating the kth second translation point to the third direction is ended, k is incremented by 1, and then the process returns to step S718, and the process ends when k>K.

[0108] After the first cycle operation and the second cycle operation are completed, steps S730 to S732 are performed.

[0109] In step S730, the room space where the first translation point and the second translation point are located is integrated.

[0110] In step S732, it is determined whether the target wall object is an inner wall or an outer wall according to the room space where the first translation point and the second translation point are located.

[0111] The wall marking method of the building model of the embodiment of the present disclosure uses one or more suitable points on a carrier (such as a wall) to perform displacement in multiple geometric spaces (such as the boundary outline of a room) to determine the characteristics of the carrier. Specifically, the target wall point (located on the carrier wall positioning line or the room dividing line) and the geometric space (i.e., the target space range) are first placed in the same plane coordinate system, and then the point displacement is used to determine whether it is inside the room space. The final displacement results are as follows:

[0112] 1. The point inside a room after being displaced once to the left and right is the exterior wall.

[0113] 2. The point after displacement to the left and right is inside the space of two rooms, and one of the two rooms is a special room and the other is a general room, which is the exterior wall.

[0114] 3. A point that is inside two room spaces after being displaced once to the left and right is an inner wall, and both room spaces are special rooms or ordinary rooms.

[0115] Based on the concepts of interior and exterior walls, the above three results are used to judge the interior and exterior walls and obtain the offset rules, so as to realize accurate automatic marking of the walls of the building model.
