Description

Marking generation method and device, terminal equipment and storage medium

Technical Field

The present invention relates to the field of image processing technologies, and in particular, to a method and apparatus for generating a reticle, a terminal device, and a storage medium.

Background

When a two-dimensional building structure is displayed, marking lines for indicating the building structure are usually drawn on four sides around the building structure, and the marking lines are provided with marking points corresponding to the building structure and distances between adjacent marking points, so that a user can know the sizes of all structures in the building structure.

In the related art, a center point is generally used to generate a line for each direction for a building structure, for example, when a line for a building structure above the center point is generated, the center point of the building structure is first determined, then the line for the building above the center point is drawn from the corner points of the room above the center point, and when a line for a building structure below the center point is generated, the center point of the building structure is also first determined, and then the line for the building above the corner points of the room below the center point is drawn from the corner points of the room below the center point.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Example 1

Detailed description of the invention the method for generating the marking line is provided in the embodiment of the invention.

Referring to fig. 1, a flowchart of steps of a method for generating a reticle according to an embodiment of the present invention is shown.

And step 101, projecting the house structure diagram into a two-dimensional plane coordinate system.

In the embodiment of the invention, the house structure diagram refers to a graph capable of showing the planar structure of a building, such as a house type graph, a decoration graph, a planar design graph and the like. The house structure diagram can be directly drawn on a two-dimensional plane or can be obtained by projection of a house three-dimensional structure diagram on the plane, and the determining mode of the house structure diagram is not particularly limited in the embodiment of the invention.

Referring to fig. 2, fig. 2 illustrates a building structure diagram according to an embodiment of the present invention, and as shown in fig. 2, the building structure diagram may represent a building structure in a top view, where lines in the building structure diagram represent boundaries between walls or different building areas.

The building block diagram may be projected into a two-dimensional planar coordinate system to determine endpoint coordinates in the building block diagram in a subsequent step and to map the building block diagram with a reticle.

In general, the building structure is formed by vertical straight lines, and when the building structure is projected to the two-dimensional plane coordinate system, the trend of the lines in the building structure can be kept parallel to the transverse axis and the longitudinal axis in the two-dimensional plane coordinate system as much as possible, so that the drawn marking can be parallel to the wall of the building, and the aesthetic degree of the marking is improved.

When the building structure diagram shown in fig. 2 is projected onto the two-dimensional plane coordinate system, the center point of the building structure diagram can be aligned with the origin of coordinates of the two-dimensional plane coordinate system, and the longitudinal line in the building structure diagram is parallel to the longitudinal axis of the two-dimensional plane coordinate system, and the transverse line in the building structure diagram is parallel to the transverse axis of the two-dimensional plane coordinate system.

And 102, extracting two first end point coordinates of each room area on one side of the target direction in the house structure diagram to obtain a first coordinate set formed by a plurality of first end point coordinates.

In the embodiment of the invention, the marking can be drawn only in one direction of the building structure, for example, the marking can be drawn on the left side or the right side of the building structure, or the marking can be drawn in a plurality of directions of the building structure, for example, the marking can be drawn in four directions around the building structure.

To draw a reticle of a building structure in a target direction of a building structure diagram, first, all room areas in the building structure diagram may be identified, and two first end coordinates of each room area on one side of the target direction may be acquired. The room area may include an independent area in a house structure diagram such as an area of a room, an area of a corridor, an area of a balcony, an area of a vestibule, and the like.

Referring to fig. 3, fig. 3 shows a schematic diagram of an endpoint provided by an embodiment of the present invention, as shown in fig. 3, the target direction is the direction indicated by the arrow w in fig. 3, and the building structure diagram includes a room area a and a room area B, so that two first endpoints of the room area a on one side of the target direction w are an endpoint 111 and an endpoint 112, and two first endpoints of the room area B on one side of the first direction a are an endpoint 121 and an endpoint 122. The first endpoint coordinate corresponding to the endpoint 111 is the coordinate of the endpoint 111 in the two-dimensional plane coordinate system after the building structure diagram is projected to the two-dimensional plane coordinate system.

After determining the two first endpoint coordinates corresponding to all the room areas, all the first endpoint coordinates can be put into the set to obtain a first coordinate set.

For example, if the coordinates of the endpoint 121 in the two-dimensional plane coordinate system shown in fig. 3 are (x 1, y 1) and the coordinates of the endpoint 122 in the two-dimensional plane coordinate system are (x 1, y 1), the endpoint coordinates (x 1, y 1) and the endpoint coordinates (x 2, y 2) corresponding to the house area a may be added to the first coordinate set.

Step 103, removing the first end point coordinates, which are blocked by the target edge line segment at one side of the target direction, in the first coordinate set from the first coordinate set to obtain a second coordinate set; the target edge line segment is formed by connecting the coordinates of the two first end points.

In the embodiment of the present invention, the target edge line segment refers to a connecting line between two first end coordinates of the room area, as shown in fig. 3, where the line segment 11 is formed by connecting an end 111 and an end 112 of the room area a, and then the line segment 11 is the target edge line segment of the room area a. The line segment 12 is formed by connecting the end point 121 and the end point 122 of the room area B, and the line segment 12 is a target edge line segment of the room area B.

It should be noted that, in the actual application process, two first end point coordinates of the room area may be determined first, then a target edge line segment corresponding to the room area may be determined according to a connection line of the two first end point coordinates, or a target edge line segment corresponding to the room area may be determined first, and then two first end point coordinates corresponding to the room area may be determined according to the target edge line segment. The order of determining the first endpoint coordinates and the target edge line segments can be flexibly adjusted by a technician according to actual needs, which is not particularly limited in the embodiment of the present invention.

After the first coordinate set is obtained, the first endpoint coordinates in the first coordinate set may be traversed, and for each first endpoint coordinate, it may be determined whether the first endpoint coordinate is blocked by a target edge line segment on one side of the target direction of the first endpoint coordinate, where it is noted that the blocking may refer to that a projection point of the first endpoint coordinate in the first direction is located above the target edge line segment.

For example, as shown in fig. 3, when the first end point 111 of the room area a is blocked in the target direction w by the target edge line segment 14 of the room area D on the target direction w side thereof, the first end point coordinate corresponding to the first end point 111 is removed from the first coordinate set, and when the first end point 112 of the room area a is not blocked by any target edge line segment on the target direction w side, the first end point coordinate corresponding to the first end point 112 of the room area a is retained in the first coordinate set.

And 104, drawing a target marking line of the house structure diagram in the target direction based on the target coordinate set.

After the target coordinate set is obtained, the target coordinate set includes first end point coordinates of all the room areas on one side of the target direction, so that a target marking line of the building structure on one side of the target direction can be drawn according to the first end point coordinates, and the target marking line is used for indicating the length of structures such as side walls of the target direction of each room area in the building structure.

Specifically, the abscissa or ordinate values of all the first end coordinates in the target coordinate set may be extracted based on the trend of the target mark to be drawn, if the target mark to be drawn is parallel to the longitudinal axis in the two-dimensional plane coordinate system, the ordinate values of the first end coordinates are extracted, and if the target mark to be drawn is parallel to the transverse axis in the two-dimensional plane coordinate system, the abscissa values of the first end coordinates are extracted.

Under the condition that the target mark line to be drawn is parallel to the longitudinal axis in the two-dimensional plane coordinate system, the abscissa value of the target mark line can be determined according to the preset drawing position of the target mark line, the abscissa value of the target mark line and the extracted ordinate value of the first end point coordinate are combined to form mark points, each mark point is drawn in the two-dimensional plane coordinate system, and connecting lines of each mark point are drawn, so that the target mark line is obtained.

Under the condition that the target mark line to be drawn is parallel to the transverse axis in the two-dimensional plane coordinate system, the longitudinal coordinate value of the target mark line can be determined according to the preset drawing position of the target mark line, the longitudinal coordinate value of the target mark line and the extracted horizontal coordinate value of the first end point coordinate are combined to form mark points, each mark point is drawn in the two-dimensional plane coordinate system, and connecting lines of each mark point are drawn, so that the target mark line is obtained.

In the embodiment of the invention, after the target marking in one direction around the building structure diagram is drawn, the target direction can be determined again, and the steps are adopted to continue drawing the target marking in other directions until the target marking in four directions around the building structure diagram is drawn.

It should be noted that, according to the first end point coordinates corresponding to two adjacent points of the marking, the corresponding size marks, for example, 2.5m, 250cm, etc., may be displayed near the two adjacent points, in the actual distance in the building structure.

In summary, the method for generating the marking provided by the invention comprises the following steps: projecting the house structure diagram into a two-dimensional plane coordinate system; extracting two first end point coordinates of each room area on one side of a target direction in a house structure diagram to obtain a first coordinate set formed by a plurality of first end point coordinates; removing the first end point coordinates, which are blocked by the target edge line segment at one side of the target direction, in the first coordinate set from the first coordinate set to obtain a second coordinate set; the target edge line segment is formed by connecting two first end point coordinates; and drawing a target marking line of the house structure diagram in the target direction based on the target coordinate set. Therefore, each marking around the house structure drawing board can be drawn according to the endpoints of all room areas which can be observed on one side of the marking, so that the marking can completely fit the size of the whole house structure, the size of each room area can be accurately described, and the marking drawing accuracy is improved.

Example two

Referring to fig. 4, a flowchart illustrating specific steps of another method for generating a reticle according to an embodiment of the present invention may include the following steps:

step 201, projecting the house structure diagram into a two-dimensional plane coordinate system.

In this step, reference is made to step 101, which is not repeated in the embodiment of the present invention.

Step 202, obtaining target edge line segments of all room areas on one side of a target direction in the house structure diagram.

In the embodiment of the invention, in order to draw the target marking line of the house structure diagram on one side of the target direction, firstly, the room area in the house structure diagram can be identified, and the target edge line segment on one side of the target direction in all the room areas can be obtained.

As shown in fig. 3, if the target direction is left, the target edge line segment of the room area a is a line segment corresponding to the wall on the left side of the room area a, that is, the target edge line segment 11. The target edge line segment of the room area B is the line segment corresponding to the wall on the left side of the room area B, i.e., the target edge line segment 12.

Optionally, step 202 further includes:

in step 2021, a plurality of edge line segments surrounding the room area in the building block diagram are obtained.

In the embodiment of the invention, in order to obtain the target edge line segments of the room area, all the edge line segments of the room area can be obtained first, and then the edge line segments matched with the target direction are found out from all the edge line segments of the room area to obtain the target edge line segments.

For example, as shown in fig. 3, if the target edge line segment of the room area a is to be determined, all edge line segments of the room area a may be obtained first, that is, four edge line segments surrounding the room area a are obtained, and then the four edge line segments are respectively matched with the target direction, so as to determine the target edge line segment corresponding to the room area a.

Substep 2022, determining an edge line segment of the plurality of edge line segments that is perpendicular to the target direction and that is near the target direction as a target edge line segment of the room region.

In the embodiment of the present invention, since the target edge line segment of each room area is an edge line segment of the room area on one side of the target direction, that is, the target edge line segment is perpendicular to the target direction, further, since the room area may correspond to a plurality of edge line segments perpendicular to the target direction, the target edge line segment also needs to be the edge line segment closest to one side of the target direction among all edge line segments perpendicular to the target direction, which correspond to the room area.

Specifically, an edge line segment which is perpendicular to the target direction and is close to the target direction among the plurality of edge line segments may be determined as a target edge line segment of the room area.

For example, as shown in fig. 3, the room area a corresponds to four edge line segments, wherein the edge line segments 11 and 21 are perpendicular to the target direction, and the edge line segments 11 are closer to the target direction w than the edge line segments 21, so the edge line segments 11 can be determined as the target edge line segments corresponding to the room area a.

Step 203, obtaining two first end point coordinates of the target edge line segment in the two-dimensional plane coordinate system.

In the embodiment of the invention, two end points of one target edge line segment are two first end point coordinates of one room area, so that after the target edge line segments corresponding to each room area are determined, the end point coordinates of the target edge line segments can be obtained, and the two first end point coordinates corresponding to the room area are obtained.

And 204, adding the first endpoint coordinates into an initial set according to the distribution sequence of the target edge line segments in the two-dimensional plane coordinate system to obtain a first coordinate set.

The distribution order of the target edge line segments in the two-dimensional plane coordinate system may refer to the distribution order of each target edge line segment in the two-dimensional plane coordinate system along the target direction, or may refer to the distribution order along the opposite direction of the target direction.

For example, as shown in fig. 3, the distribution order of the target edge line segments of each room area along the target direction w is an edge line segment 12, an edge line segment 11, an edge line segment 13, an edge line segment 14, an edge line segment 16, an edge line segment 15, an edge line segment 17, an edge line segment 18. It should be noted that if a plurality of target edge line segments are located at the same position in the target direction (for example, the edge line segment 11 and the edge line segment 13 in fig. 3), the order between the plurality of target edge line segments may be arbitrarily adjusted.

In the embodiment of the invention, all the first endpoint coordinates can be added into an initial set according to the distribution sequence of the corresponding target edge line segments in the two-dimensional plane coordinate system, so as to obtain a first coordinate set containing all the first endpoint coordinates. It should be noted that, for two first endpoint coordinates corresponding to the same target edge line segment, when the two first endpoint coordinates are added to the initial set, the first endpoint coordinates of one azimuth may precede the first endpoint coordinates of the other azimuth, or the sequence between the two first endpoint coordinates may not be limited.

For example, let the coordinates of the two first end points corresponding to the target edge line segment 11 be A1 and A2, the coordinates of the two first end points corresponding to the target edge line segment 12 be B1 and B2, the coordinates of the two first end points corresponding to the target edge line segment 13 be C1 and C2, and so on. The first endpoint coordinates are added to the initial set according to the distribution sequence of the target edge line segments along the target direction in the two-dimensional plane coordinate system, and the obtained first coordinate set can be [ B1, B2, A1, A2, C1, C2, D1, D2, F1, F2, E1, E2, G1, G2, H1, H2].

And 205, traversing the first end point coordinates corresponding to each target edge line segment in the first coordinate set in a reverse order.

In the embodiment of the invention, the traversal can be started from the first end point coordinate corresponding to the target edge line segment at one side far away from the target direction until the first end point coordinate corresponding to the target edge line segment at one side closest to the target direction is traversed.

Since the first coordinate set obtained by adding the first end point coordinates to the initial set according to the distribution order of the target edge line segments in the two-dimensional plane coordinate system when the first coordinate set is generated in the foregoing step, the starting point position from which the traversal starts can be selected from the first coordinate set according to the distribution order.

Specifically, in the case that the distribution sequence is that each target edge line segment is in the two-dimensional plane coordinate system and along the target direction, the whole first coordinate set may be traversed from the first endpoint coordinate of the first coordinate set. In the above-mentioned distribution sequence, when each target edge line segment is in the two-dimensional plane coordinate system and is in the opposite direction to the target direction, the whole first coordinate set may be traversed from the last first endpoint coordinate of the first coordinate set.

In the embodiment of the invention, the first coordinate set is generated through the distribution sequence of the target edge line segments, and each first endpoint coordinate in the first coordinate set is sequentially traversed from the starting position/the ending position of the first coordinate set according to the distribution sequence, so that the first endpoint coordinate can be sequentially traversed according to the distribution condition of the first endpoint coordinate on the plane without analyzing the arrangement sequence of the first endpoint coordinate in the two-dimensional plane coordinate system in the traversing process, and the traversing efficiency is improved.

And 206, determining the traversed first endpoint coordinate as a second endpoint coordinate when the extension line of the traversed first endpoint coordinate in the target direction intersects with the target edge line segment corresponding to the first endpoint coordinate which is not traversed.

In the embodiment of the invention, if the first endpoint coordinate is blocked by other target edge line segments at one side of the target direction, it is indicated that the first endpoint coordinate cannot be directly observed from one side of the target line to be generated, the target point corresponding to the first endpoint coordinate may not appear on the target line corresponding to the target direction, and the target point corresponding to the first endpoint coordinate may appear on other target lines corresponding to other directions, so that the effect of the generated line is improved, and the target point on the target line is more easily corresponding to each first endpoint.

For example, referring to fig. 5, fig. 5 shows a schematic diagram of a reticle provided in an embodiment of the present invention, as shown in fig. 5, a direction w corresponds to a reticle 61, a direction x corresponds to a reticle 62, a direction y corresponds to a reticle 63, and a direction z corresponds to a reticle 64. When the target direction is w, the first end point 111 of the room area a is blocked by the target edge line segment of the other room area on the w direction side thereof, and cannot be observed from the w direction side of the entire house, and therefore, the first end point 111 can be removed from the first coordinate set, and the target point corresponding to the first end point 111 is not generated on the reticle 61. When the reticle 62 corresponding to the direction x is subsequently generated, since the first end point 111 can be directly observed from the x-direction side, the reticle 621 corresponding to the first end point 111 can be generated on the reticle 62.

When traversing to a first endpoint coordinate, it can be determined whether the first endpoint coordinate is blocked by a target edge line segment on one side of the target direction of the first endpoint coordinate, and it should be noted that the blocking refers to that a projection point of the first endpoint coordinate in the first direction is located above the target edge line segment. In the embodiment of the invention, an extension line of the first endpoint coordinate can be made along the target direction, whether the extension line intersects with other target edge line segments or not is judged, if the extension line does not intersect with other target edge line segments, the next first endpoint coordinate is continuously traversed, and if the extension line intersects with other target edge line segments, the first endpoint coordinate is determined as the second endpoint coordinate.

Specifically, since in the first coordinate set, the two first end point coordinates corresponding to each target edge line segment always appear in adjacent pairs, and the first end point coordinates in the first coordinate set are arranged in the order of distribution of the corresponding target edge line segments in the two-dimensional plane coordinate system, it is possible for each traversed first end point coordinate to be compared with the two first end point coordinates corresponding to each non-traversed target edge line segment in the first coordinate set before or after it, so as to determine whether or not the extension line of the traversed first end point coordinate in the target direction intersects with other target edge line segments.

And under the condition that the target direction is parallel to the x axis of the two-dimensional plane coordinate system, comparing the ordinate values of the traversed first endpoint coordinates with the two first endpoint coordinates corresponding to all the non-traversed target edge line segments, if the ordinate values of the traversed first endpoint coordinates are larger than the ordinate values of one first endpoint coordinate corresponding to a certain non-traversed target edge line segment and smaller than the ordinate values of the other first endpoint coordinate corresponding to the non-traversed target edge line segment, the extension line of the traversed first endpoint coordinates in the target direction is intersected with the non-traversed target edge line segment, and determining the first endpoint coordinates as second endpoint coordinates.

For example, as shown in fig. 3, in the case where the first coordinate set is [ B1, B2, A1, A2, C1, C2, D1, D2, F1, F2, E1, E2, G1, G2, H1, H2], since the first end coordinates are added to the initial set in the order of distribution of the target edge line segments along the target direction when the first coordinate set is generated, the first coordinate set may be traversed from the start position of the first coordinate set, and when traversing to the 12 th first end coordinate E2, it may be determined whether the ordinate value corresponding to the first end coordinate E2 is located between the ordinate values of the two first end coordinates G1 and G2 corresponding to the target edge line segment 17, if the determination result is no, it may be continued to determine whether the ordinate value corresponding to the first end coordinate E2 is located between the ordinate values of the two first end coordinates H1 and H2 corresponding to the target edge line segment 18, and if the determination result is yes, it may be determined that the first end coordinate E2 is the second end point.

In the embodiment of the invention, all the first endpoint coordinates can be traversed from the first endpoint coordinates far away from the target direction, and the first endpoint coordinates which are traversed currently are compared with the first endpoint coordinates which are not traversed currently, so that whether the first endpoint coordinates which are traversed currently need to be reserved or not is determined, the speed of traversing the first endpoint coordinates is improved, all the first endpoint coordinates which can be observed from the target direction can be reserved, and therefore a more complete target marking is drawn on one side of the target direction.

And step 207, drawing a target marking of the house structure diagram in the target direction based on the second coordinate set.

In an embodiment of the present invention, the target direction may include a transverse axis direction, a transverse axis opposite direction, a longitudinal axis direction, and a longitudinal axis opposite direction of the two-dimensional planar coordinate system. Therefore, there is also a difference in the trend of the target reticle to be drawn in the two-dimensional plane coordinate system based on the difference in the target direction, the drawn target reticle is parallel to the longitudinal axis direction if the target direction is parallel to the transverse axis direction, and the drawn target reticle is parallel to the transverse axis direction if the target direction is parallel to the longitudinal axis direction.

Optionally, step 207 further comprises:

sub-step 2071, extracting ordinate of each endpoint coordinate in the second coordinate set, and drawing a target marking outside the target direction of the building structure according to the ordinate, when the target direction is parallel to the horizontal axis of the two-dimensional plane coordinate system.

As shown in fig. 5, if the target direction is the direction w, that is, the target direction is parallel to the horizontal axis, the ordinate of each endpoint coordinate in the second coordinate set corresponding to the target direction w may be extracted, the abscissa of the reticle may be determined, the same number of endpoint coordinates as the endpoint coordinates in the second coordinate set may be generated according to the abscissa of the reticle and the ordinate of each endpoint coordinate, each endpoint coordinate may be drawn in the two-dimensional plane coordinate system, and the connection line between each endpoint coordinate may be generated, so as to obtain the reticle 61 corresponding to the target direction w, and the endpoint 611 on the reticle 61.

It should be noted that, the abscissa may be calculated based on a preset distance from the building structure, for example, when the target direction is the negative direction of the horizontal axis, the minimum abscissa of all points in the building structure is determined, and then the minimum abscissa is subtracted by a preset distance to obtain the abscissa value corresponding to the target marking in the target direction. The technician may also determine the generation position of each marking line in other manners, and embodiments of the present invention are not specifically limited herein.

Further, if the distance between two adjacent targets in the marker line is too short, the target adhesion may not be distinguished, and the display effect of the generated marker line is affected. Specifically, the merging may be removing one of the two adjacent punctuations, or generating a new punctuation between the two adjacent punctuations, and removing the two adjacent punctuations from the reticle, and the technician may also merge the two adjacent punctuations in other manners according to actual needs, which is not limited in particular by the embodiment of the present invention.

Sub-step 2072, extracting the abscissa of each endpoint coordinate in the second coordinate set, and drawing a target marking outside the target direction of the building structure according to the abscissa, when the target direction is parallel to the longitudinal axis of the two-dimensional plane coordinate system.

This step is similar to the above-described substep 2071, and the embodiments of the present invention will not be described again.

In summary, another method for generating a reticle according to the present invention includes: projecting the house structure diagram into a two-dimensional plane coordinate system; extracting two first end point coordinates of each room area on one side of a target direction in a house structure diagram to obtain a first coordinate set formed by a plurality of first end point coordinates; removing the first end point coordinates, which are blocked by the target edge line segment at one side of the target direction, in the first coordinate set from the first coordinate set to obtain a second coordinate set; the target edge line segment is formed by connecting two first end point coordinates; and drawing a target marking line of the house structure diagram in the target direction based on the target coordinate set. Therefore, each marking around the house structure drawing board can be drawn according to the endpoints of all room areas which can be observed on one side of the marking, so that the marking can completely fit the size of the whole house structure, the size of each room area can be accurately described, and the marking drawing accuracy is improved.
