Description

Technical Field

[0001] This invention relates to the field of graphic data reading and image data processing technology, and in particular to a method, device, medium, equipment and product for transforming the position of architectural plan elements based on dual positioning lines. Background Technology

[0002] In architectural planning and surveying, layout plans are a crucial technical basis for construction layout. Traditionally, the creation of layout plans requires analysis of planning and approval drawings, overlaying multiple layered plans onto the same coordinate system to determine the precise location and axial relationships of the building.

[0003] Currently, CAD software such as AutoCAD provides basic graphic editing and transformation functions, including commands for moving, rotating, and aligning. However, when performing alignment operations on complex architectural floor plans, these commands typically require operators to manually select the elements to be processed and, based on the axes, positioning lines, or architectural outlines in the drawing, determine the target position where each element should be aligned before performing move, rotate, or other operations. For architectural floor plans containing multiple architectural outlines, multiple layered floor plans, or multiple elements to be aligned, the above processing method is not only cumbersome but also makes it difficult to achieve batch alignment of elements.

[0004] Furthermore, during manual alignment, the correspondence between the elements to be transformed and the reference axes usually relies on the operator's experience, which can easily lead to problems such as incorrect element matching, inconsistent reference point selection, and deviations in rotation angles. Especially when multiple elements need to be moved and rotated continuously, errors generated by manual operation may gradually accumulate, causing the original positional relationships between the building outlines to shift. This results in inaccurate relative positions of building outlines, positioning axes, or layered elements in the generated layout plan, thus affecting the accuracy of subsequent construction layout. Summary of the Invention

[0005] The purpose of this invention is to propose a method, device, medium, equipment, and product for transforming the position of architectural plan elements based on dual positioning lines. By setting a reference axis and a target axis to be transformed in the architectural plan, and using the reference axis as the transformation reference, the target target axis to be transformed is transformed to obtain a target transformation matrix. The target transformation matrix is ​​then applied to the target element to be transformed, thereby realizing batch alignment processing of elements and effectively improving the accuracy of element alignment.

[0006] To achieve the above objectives, a first aspect of the present invention provides a method for transforming the position of architectural plan elements based on dual positioning lines, the method comprising: Determine the reference axis in the building plan, and then determine several axes to be transformed in sequence; Based on the positional relationship between the reference point of the target graphic element to be transformed and each of the axes to be transformed, the target axis to be transformed corresponding to the target graphic element is determined; Using the reference axis as the transformation reference, the target axis to be transformed is transformed to obtain a target transformation matrix, and the target transformation matrix is ​​applied to the target primitive to be transformed to transform the target primitive.

[0007] In this embodiment, a target transformation matrix is ​​generated based on the positional transformation relationship between the target axis to be transformed and the reference axis, so that the primitives at different positions can be automatically matched and uniformly transformed according to their respective corresponding axes to be transformed, thereby improving the processing efficiency and accuracy of primitive position transformation.

[0008] Furthermore, the process of determining a reference axis in the building plan and sequentially determining a plurality of axes to be transformed includes: A first positioning line and a second positioning line are set in the building plan. The first positioning line and the second positioning line are both polysegment lines, and the first positioning line and the second positioning line each include a number of segments that are of the same number and in corresponding order. A reference starting point is determined from the segment points of the first positioning line, and a reference ending point is determined from the segment points of the second positioning line; the reference axis is determined based on the reference starting point and the reference ending point; According to the arrangement order of the segment points in the first positioning line and the second positioning line, the i-th segment point in the first positioning line is determined as the starting point of the i-th axis to be transformed, and the i-th segment point in the second positioning line is determined as the ending point of the i-th axis to be transformed; the i-th axis to be transformed is determined based on the starting point and ending point of the i-th axis to be transformed, until several axes to be transformed are determined, where i is a positive integer.

[0009] In this embodiment, by setting a first positioning line and a second positioning line with the same number of segments and corresponding segment order, the corresponding segments in the two positioning lines can form a stable axis correspondence relationship. Thus, several axes to be transformed are automatically generated according to the segment arrangement order, ensuring the consistency of axis generation rules and improving the stability of subsequent primitive matching and position transformation.

[0010] Further, determining the target axis to be transformed corresponding to the target graphic element based on the positional relationship between the reference point of the target graphic element and each of the axes to be transformed includes: Based on the starting point, ending point, and preset outward distance value of each axis to be transformed, the axis association region of each axis to be transformed is determined respectively; Based on the positional relationship between the reference point of the target graphic element to be transformed and the axis-associated region of each of the axes to be transformed, the target axis to be transformed corresponding to the target graphic element is determined.

[0011] In this embodiment, by setting an axis association area for each axis to be transformed, the axis to be transformed can cover a certain range of matching areas around it, thereby adapting to actual drawing scenarios where there is a certain offset distance between architectural elements and positioning axes.

[0012] Further, determining the target axis to be transformed corresponding to the target graphic element based on the positional relationship between the reference point of the target graphic element and the axis association region of each of the axes to be transformed includes: Calculate the geometric center coordinates of the target primitive to be transformed; When the geometric center coordinates fall into only one axis-related region, the axis to be transformed corresponding to the axis-related region is determined as the target axis to be transformed corresponding to the target primitive to be transformed. When the geometric center coordinates fall into multiple axis-related regions, the Euclidean distance between the geometric center coordinates and the regional center point of each of the multiple axis-related regions is calculated respectively; and the axis to be transformed corresponding to the axis-related region with the smallest Euclidean distance is determined as the target axis to be transformed corresponding to the target primitive.

[0013] In this embodiment, by using the geometric center coordinates of the target graphic element to be transformed to represent the overall position of the graphic element, the effectiveness of determining the axis to which the graphic element belongs can be improved. Furthermore, by determining the target axis to be transformed through preset rules, an accurate axis matching basis can be provided for subsequent graphic element position transformations.

[0014] Further, the step of using the reference axis as a transformation reference to perform position transformation on the target axis to be transformed, to obtain the target transformation matrix, includes: Calculate the translation vector between the starting point of the target axis to be transformed and the starting point of the reference axis, and construct a translation transformation matrix based on the translation vector; Calculate the direction angle difference between the direction angle of the target axis to be transformed and the direction angle of the reference axis, and construct a rotation transformation matrix based on the direction angle difference; The target transformation matrix is ​​generated based on the translation transformation matrix and the rotation transformation matrix.

[0015] In this embodiment, the primitive position transformation process is decomposed into two quantifiable steps: translation transformation and rotation transformation, by calculating the translation vector and direction angle difference between the target axis to be transformed and the reference axis. Then, a target transformation matrix is ​​generated based on the translation and rotation transformation matrices, which can describe the complete position transformation relationship in a unified matrix form, achieving consistency in primitive position transformation.

[0016] Further, applying the target transformation matrix to the target primitive to be transformed to perform a positional transformation on the target primitive includes: Obtain the coordinates of each vertex of the target primitive to be transformed; The target transformation matrix is ​​applied to the coordinates of each vertex to obtain the target vertex coordinates corresponding to each vertex, and the position transformation of the target primitive to be transformed is performed based on the target vertex coordinates.

[0017] In this embodiment, by applying the target transformation matrix to each vertex of the target primitive to be transformed, all vertices of the same primitive are transformed synchronously according to the same translation and rotation relationships, thereby improving the accuracy of primitive transformation.

[0018] To achieve the above objectives, a second aspect of the present invention also provides a device for transforming the position of architectural plan elements based on dual positioning lines, used to implement the method for transforming the position of architectural plan elements based on dual positioning lines as described in any of the first aspects, the device comprising: The axis generation module is used to determine the reference axis in the building plan and sequentially determine several axes to be transformed; The transformation axis determination module is used to determine the target transformation axis corresponding to the target graphic element based on the positional relationship between the reference point of the target graphic element to be transformed and each of the transformation axes; The primitive position transformation module is used to perform position transformation on the target axis to be transformed using the reference axis as the transformation reference, to obtain a target transformation matrix, and to apply the target transformation matrix to the target primitive to be transformed in order to perform position transformation on the target primitive to be transformed.

[0019] A third aspect of the present invention also provides a computer-readable storage medium, the computer-readable storage medium including a stored computer program; wherein, when the computer program is executed, it controls the device where the computer-readable storage medium is located to perform the method for transforming the position of architectural plan elements based on dual positioning lines as described in any of the first aspects above.

[0029] The technical solution of the present invention will be further described below with reference to specific embodiments: The first aspect of this invention provides a method for transforming the position of architectural plan elements based on dual positioning lines, see [link to relevant documentation]. Figure 1 The diagram shown is a flowchart of a preferred embodiment of a method for transforming the position of architectural plan elements based on dual positioning lines provided in the first aspect of the present invention. The method includes steps S1 to S3, as follows: Step S1: Determine the reference axis in the building plan, and then determine several axes to be transformed in sequence; The building plan can be a layout plan, planning and approval plan, floor plan, building outline, or other two-dimensional plan containing building elements, used in architectural planning and surveying. The reference axis refers to an axis in the building plan that serves as a reference for position transformation, providing the reference position and direction for the target element to be transformed. The axis to be transformed refers to an axis that has a preset correspondence with the reference axis and is used to determine the position and direction of the element before transformation. Several axes to be transformed can be generated sequentially based on double positioning lines in the building plan, or determined sequentially based on pre-set positioning lines, axes, or auxiliary lines in the building plan.

[0030] In one example, a first positioning line and a second positioning line are set on the building plan. Both the first and second positioning lines are polylines, and each includes the same number of sequentially corresponding segment points. The system can determine a reference starting point from the segment points of the first positioning line and a reference ending point from the segment points of the second positioning line, connecting the reference starting point and the reference ending point to form a reference axis. Then, according to the arrangement order of the segment points in the first and second positioning lines, the system uses the i-th segment point in the first positioning line as the starting point of the i-th axis to be transformed and the i-th segment point in the second positioning line as the ending point of the i-th axis to be transformed, thereby sequentially determining several axes to be transformed. Thus, a set of axes can be automatically generated from sequentially corresponding segment points in the two positioning lines.

[0031] Step S2: Determine the target axis to be transformed corresponding to the target graphic element based on the positional relationship between the reference point of the target graphic element to be transformed and each of the axes to be transformed; The target graphic element to be transformed refers to a graphic object in the building plan that needs to undergo positional transformation, such as a building outline, building outer boundary, polyline graphic element, closed graphic element, or other graphic element that can be represented by vertex coordinates. The reference point refers to a point used to characterize the overall position of the target graphic element to be transformed, which can be the geometric center point, the center point of the circumscribed rectangle, the centroid point, or a pre-specified graphic element positioning point. The target axis to be transformed refers to the axis to be transformed corresponding to the target graphic element, determined from a plurality of axes to be transformed, and is used as the axis for positional transformation of the target graphic element.

[0032] In one example, the system can determine the axis association region for each axis to be transformed based on its start point, end point, and a preset outward distance value. The axis association region can be understood as the effective matching area around the axis to be transformed. Then, the system calculates the geometric center coordinates of the target primitive to be transformed and determines the positional relationship between these coordinates and each axis association region. When the geometric center coordinates fall within one axis association region, the axis to be transformed corresponding to that region is determined as the target axis to be transformed. When the geometric center coordinates fall within multiple axis association regions simultaneously, the Euclidean distance between the geometric center coordinates and the regional center points of each axis association region can be further calculated, and the axis to be transformed corresponding to the axis association region with the smallest Euclidean distance is determined as the target axis to be transformed.

[0033] Step S3: Using the reference axis as the transformation reference, perform position transformation on the target axis to be transformed to obtain the target transformation matrix, and apply the target transformation matrix to the target primitive to be transformed to perform position transformation on the target primitive to be transformed.

[0034] The target transformation matrix refers to a matrix used to describe the positional transformation relationship required for the target axis to be transformed to the reference axis. The target transformation matrix may include translation transformation information and rotation transformation information, used to transform the target primitive to be transformed from its current position and direction corresponding to the axis to the position and direction corresponding to the reference axis.

[0035] In one example, the system first calculates the translation vector between the starting point of the target axis to be transformed and the starting point of the reference axis, and constructs a translation transformation matrix based on the translation vector. Next, it calculates the direction angle difference between the direction angle of the target axis to be transformed and the direction angle of the reference axis, and constructs a rotation transformation matrix based on the direction angle difference. Finally, it generates a target transformation matrix based on the translation and rotation transformation matrices. Afterward, the system obtains the vertices of each primitive to be transformed, applies the target transformation matrix to each primitive vertex, and obtains the target vertex coordinates corresponding to each primitive vertex, thereby completing the position transformation of the target primitive.

[0036] For example, a building plan may include multiple building outline elements, each located near a different axis to be transformed. The system automatically determines the corresponding target axis to be transformed based on the geometric center coordinates of each building outline element. Then, it calculates the translation and rotation relationships between each target axis to be transformed and the reference axis, and applies the corresponding target transformation matrix to each vertex of the building outline element. In this way, building outline elements distributed in different locations and directions can be batch-transformed to positions and directions corresponding to the reference axis, achieving automatic alignment of building plan elements.

[0037] In another preferred embodiment, determining a reference axis in the building plan and sequentially determining a plurality of axes to be transformed includes: A first positioning line and a second positioning line are set in the building plan. The first positioning line and the second positioning line are both polysegment lines, and the first positioning line and the second positioning line each include a number of segments that are of the same number and in corresponding order. A reference starting point is determined from the segment points of the first positioning line, and a reference ending point is determined from the segment points of the second positioning line; the reference axis is determined based on the reference starting point and the reference ending point; According to the arrangement order of the segment points in the first positioning line and the second positioning line, the i-th segment point in the first positioning line is determined as the starting point of the i-th axis to be transformed, and the i-th segment point in the second positioning line is determined as the ending point of the i-th axis to be transformed; the i-th axis to be transformed is determined based on the starting point and ending point of the i-th axis to be transformed, until several axes to be transformed are determined, where i is a positive integer.

[0038] See Figure 2 This is a schematic diagram of the correspondence between two positioning lines and vertices, representing another preferred embodiment of a method for transforming the position of architectural plan elements based on two positioning lines provided in the first aspect of the present invention. A two-dimensional coordinate system is established in the architectural plan, with the horizontal axis being the X-axis and the vertical axis being the Y-axis. A first positioning line L1 and a second positioning line L2 are set in the architectural plan. The first positioning line L1 is a blue polyline in the diagram, and the second positioning line L2 is a red polyline in the diagram. Both L1 and L2 include a number of segments arranged in sequence, and the number of segments in L1 and L2 is the same.

[0039] In one example, let the first positioning line and the second positioning line be respectively and Both include Each segment point, and The segment points of the two positioning lines correspond one-to-one according to their serial numbers:

[0045] To accommodate user-specified reference axes, the starting point of the reference axis is set as:

[0046] The endpoint of the reference axis is:

[0047] By default, The direction vector of the reference axis Represented as:

[0048] in:

[0049] In architectural floor plan alignment scenarios, the axis direction is typically calculated in the XY plane; therefore, the direction angle of the reference axis relative to the positive X-axis direction is... Represented as:

[0050] For the Current axis Its direction vector and direction angle are as follows:

[0051]

[0052] in:

[0053] In yet another preferred embodiment, determining the target axis to be transformed corresponding to the target graphic element based on the positional relationship between the reference point of the target graphic element and each of the axes to be transformed includes: Based on the starting point, ending point, and preset outward distance value of each axis to be transformed, the axis association region of each axis to be transformed is determined respectively; Based on the positional relationship between the reference point of the target graphic element to be transformed and the axis-associated region of each of the axes to be transformed, the target axis to be transformed corresponding to the target graphic element is determined.

[0054] In one example, for the first Axis Let its starting point be:

[0055] The destination is:

[0056] To determine whether a candidate primitive belongs to the axis, the axis is constructed in the XY plane. Corresponding extended rectangular area .

[0057] set up This refers to the outward expansion distance parameter, in millimeters. This can be set by the user; the default value is 5000mm. This expands the rectangular area. The boundary is:

[0058] Therefore, the rectangular area is expanded. It can be represented as:

[0059] The formula outputs not a single coordinate point, but a two-dimensional rectangular region. This rectangular region can be defined by its lower left corner point. and the top right corner The only certainty.

[0060] In yet another preferred embodiment, determining the target axis to be transformed corresponding to the target graphic element based on the positional relationship between the reference point of the target graphic element to be transformed and the axis association region of each of the axes to be transformed includes: Calculate the geometric center coordinates of the target primitive to be transformed; When the geometric center coordinates fall into only one axis-related region, the axis to be transformed corresponding to the axis-related region is determined as the target axis to be transformed corresponding to the target primitive to be transformed. When the geometric center coordinates fall into multiple axis-related regions, the Euclidean distance between the geometric center coordinates and the regional center point of each of the multiple axis-related regions is calculated respectively; and the axis to be transformed corresponding to the axis-related region with the smallest Euclidean distance is determined as the target axis to be transformed corresponding to the target primitive.

[0061] In one example, let the first... The geometric center points of the candidate primitives are:

[0062] like satisfy and If the candidate primitive falls into the first position, then it is determined that the candidate primitive falls into the first position. An extended rectangular region along the axis.

[0063] When a candidate primitive falls into multiple extended rectangular regions simultaneously, calculate the geometric center point of each candidate primitive. Center point of each candidate extended rectangular region The distance between them is determined, and the axis with the smallest distance is selected as the target axis.

[0064] Expanding rectangular area center point Represented as:

The candidate primitive was matched to the first... A single axis line.

[0067] See Figure 3 This is a schematic diagram of the axis association region and element matching relationship of an axis to be transformed, which is another preferred embodiment of a method for transforming the position of architectural plan elements based on dual positioning lines provided in the first aspect of the present invention. The diagram shows an axis to be transformed. For example, the axis to be transformed starts from the starting point. and the end point Confirmed. Based on the start and end points of the axis to be transformed and the preset outward distance value offset, an axis-related region is constructed around the axis to be transformed. The range of the axis-related region is shown in the figure with a blue dashed box, where offset represents the outward distance of the axis to be transformed in the preset direction.

[0068] Within the area associated with this axis, several candidate graphic elements are set, such as the candidate graphic elements in the figure. , and The orange dots inside each candidate primitive represent the geometric center point of the corresponding candidate primitive. Because the candidate primitives... , and Since the geometric center points of all elements fall within the area associated with the axis, the candidate primitives can be determined. , and With the axis to be transformed Match successful. The successfully matched candidate elements are indicated by a yellow border in the figure. Additionally, unmatched candidate elements are also shown in the figure. and Among them, candidate primitives Candidate primitives located outside the area associated with the axis The geometric center point also does not fall within the area associated with the axis; therefore, the candidate primitive can be determined. and With the axis to be transformed Mismatch. The gray borders in the diagram indicate the unmatched candidate elements.

[0069] In yet another preferred embodiment, the step of using the reference axis as a transformation reference to perform a position transformation on the target axis to be transformed, thereby obtaining a target transformation matrix, includes: Calculate the translation vector between the starting point of the target axis to be transformed and the starting point of the reference axis, and construct a translation transformation matrix based on the translation vector; Calculate the direction angle difference between the direction angle of the target axis to be transformed and the direction angle of the reference axis, and construct a rotation transformation matrix based on the direction angle difference; The target transformation matrix is ​​generated based on the translation transformation matrix and the rotation transformation matrix.

[0070] In one example, for the match to the Axis Candidate primitives need to be calculated from the current axis. To the reference axis The coordinate transformation includes translation and rotation.

[0071] For translation transformations, first calculate the starting point of the current axis. To the reference starting point Translation vector :

(Based on the reference starting point) Rotate around the Z-axis with the Z-axis as the center of rotation. The rotation matrix is ​​obtained. In two-dimensional planar representation, its equivalent transformation relationship is:

[0076] The above expression indicates that the point Rotate in the XY plane around the reference starting point A new point was obtained later. In actual matrix calculations, the rotation matrix... It can be determined by the rotation angle Rotation axis Z-axis and rotation center The only certainty.

[0077] Multiply the translation and rotation matrices to obtain the combined transformation matrix. :

[0078] This embodiment uses column vectors to represent point coordinates and performs coordinate transformation by multiplying the column vectors by a transformation matrix on the left. Therefore... This means that a translation transformation is performed on the point first, followed by a rotation transformation.

[0079] In yet another preferred embodiment, applying the target transformation matrix to the target primitive to be transformed to perform a positional transformation on the target primitive includes: Obtain the coordinates of each vertex of the target primitive to be transformed; The target transformation matrix is ​​applied to the coordinates of each vertex to obtain the target vertex coordinates corresponding to each vertex, and the position transformation of the target primitive to be transformed is performed based on the target vertex coordinates.

[0080] In one example, let any vertex in the candidate primitives be:

[0081] Represented in homogeneous coordinates as follows:

[0082] Then the aligned vertices homogeneous coordinates It can be represented as:

[0083] in:

[0084] These are the homogeneous coordinates of the vertices after the transformation. These are the 3D coordinates of the transformed vertices. Performing the above transformation on all vertices of the candidate primitive yields the aligned new primitive.
