Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
According to an embodiment of the application, a method for retrieving drawing size labels is provided. Alternatively, in the embodiment of the present application, the method for retrieving the drawing size label may be applied to a hardware environment formed by the terminal 101 and the server 102 as shown in fig. 1. As shown in fig. 1, a server 102 is connected to a terminal 101 through a network, which may be used to provide services (such as video services, application services, etc.) for the terminal or a client installed on the terminal, and a database may be provided on the server or separately from the server for providing data storage services for the server 102, and the network includes but is not limited to: the terminal 101 is not limited to a PC, a mobile phone, a tablet computer, and the like.
The method for retrieving drawings and dimension labels in the embodiment of the present application may be executed by the server 102, by the terminal 101, or by both the server 102 and the terminal 101. The terminal 101 executes the method for retrieving the drawing size label according to the embodiment of the present application, or may be executed by a client installed thereon.
Taking a terminal to execute the retrieval method for drawing size marking in the embodiment of the present application as an example, fig. 2 is a schematic flow chart of a retrieval method for optional drawing size marking in the embodiment of the present application, and as shown in fig. 2, the flow of the method may include the following steps:
In some embodiments, when a user needs to know the distance between two points, the two points generally need to be selected in a drawing, so that the terminal can monitor two target picked points selected by the user. The method comprises the steps that a marking direction is used as an input parameter of a query interface on a terminal, after a user clicks two target picking points, the target marking direction is input at the display position of the query interface, and therefore the target marking direction is obtained by the terminal.
For any point in the drawing, there is a corresponding coordinate. Therefore, after the target picking points are monitored by the terminal, the coordinate information of the two target picking points can be obtained. Generally, two target picking points clicked by a user are consistent with the target labeling direction or slightly deviated.
Specifically, if a connecting line of two target picking points is parallel to the target marking direction, determining coordinate information of the two target picking points as target coordinate information; if the connecting line of the two target picking points is not parallel to the target marking direction, the coordinate information of the two target picking points needs to be corrected to obtain the target coordinate information.
In an alternative embodiment, obtaining target coordinate information of two target pickup points in the drawing includes:
acquiring initial coordinate information of the target picking point; and correcting the initial coordinate information according to a labeling rule to obtain target coordinate information, wherein a connecting line of the target coordinate information of the two corrected target picking points is parallel to the target labeling direction.
In some embodiments, after a user clicks two target picking points in a drawing, a terminal acquires initial coordinate information of the two target picking points, and a connecting line of the obtained target coordinate information can be parallel to a target labeling direction after the initial coordinate information is corrected according to a labeling rule.
In an optional embodiment, the labeling rule includes a target labeling direction; correcting the initial coordinate information according to the labeling rule to obtain target coordinate information, wherein the method comprises the following steps:
determining a pickup starting point and a pickup end point in the target pickup points based on the target labeling direction; correcting the coordinate value of the picking end point in the non-target labeling direction into the coordinate value of the picking start point in the non-target labeling direction to obtain a corrected coordinate value of the picking end point, wherein the non-target labeling direction is a direction vertical to the target labeling direction; and determining coordinate values of the pickup starting point and correction coordinate values of the pickup end point as the target coordinate information.
In some embodiments, the two target pickup points selected by the user on the drawing may have some deviation from the target labeling direction, and therefore, the coordinate connection line of the two target pickup points may be corrected to be parallel to the target labeling direction.
Illustratively, two target pickup points are A, B, the coordinate of point a is (X1, Y1), the coordinate of point B is (X2, Y2), and the target labeling direction is the positive X-axis direction. When the target labeling direction is determined to be parallel to the positive direction of the X axis, the non-target labeling direction can be determined to be perpendicular to the direction of the X axis, namely the direction of the Y axis. If it is determined that point a is the pickup start point and point B is the pickup end point based on the target labeling direction, the ordinate of point B is corrected to coincide with the ordinate of point a, and the corrected coordinates of point B are obtained as (X2, Y1), and further, target coordinate information is determined as (X1, Y1) and (X2, Y1).
In an optional embodiment, the determining a pickup start point and a pickup end point of the target pickup points based on the target labeling direction includes:
sequencing the two target picking points according to the sequence of the target picking points in the target marking direction; and determining the target picking point appearing first in the target labeling direction as the picking starting point, and determining the target picking point appearing later in the target labeling direction as the picking end point.
In some embodiments, since a user may not select two target picked points according to the sequence of the target labeling directions when selecting the two target picked points, the two target picked points need to be sorted first, and then a pickup start point and a pickup end point are determined.
Illustratively, two target pickup points are A, B, the coordinates of point a are (X1, Y1), the coordinates of point B are (X2, Y2), where X1 is smaller than X2, and the target labeling direction is the positive X-axis direction. When sorting is performed in the positive direction of the X axis, since X1 is smaller than X2, point a is found first and then point B is found, and therefore point a is a pickup start point and point B is a pickup end point.
In some embodiments, after obtaining the target coordinate information of two target pickup points, a distance value between the two target pickup points may be calculated according to the two target coordinate information. It can be understood that, when the connecting line of the target coordinate information is parallel to the target labeling direction, the difference value of the coordinates in the target labeling direction in the two target coordinate information may be calculated to obtain the difference value as the distance value between the two target picking points.
It can be understood that, if the original dimension value in the dimension label is the actual dimension, after the difference is obtained, the difference can be converted into the actual distance value between the two picked points according to the scale on the drawing.
And 203, retrieving to obtain a target size label from a pre-stored label storage structure based on the target coordinate information, the distance value and the target labeling direction.
In some embodiments, when the length between two target picked points in the drawing needs to be determined, after target coordinate information and a target labeling direction between the two target picked points are obtained, a target size label can be retrieved from the label storage structure through the distance value between the two target picked points, the target coordinate information and the target labeling direction, which are obtained through calculation, so that the condition that the distance value is not accurately calculated directly by adopting coordinates of the two target picked points is avoided, the actual size between the two target picked points is obtained based on the obtained target size label, and the accuracy is improved.
It can be understood that, after the target size label is obtained, since the size value is included in the target size label, the size value in the target size label can be used as the true distance value between two target picked points.
The target size label can be obtained by screening in a label storage structure stored in advance based on the target coordinate information, the distance value and the target label direction.
In an optional embodiment, each size label in the pre-stored label storage structure comprises an original label direction, an original size value, a label starting point and a label end point;
the retrieving a target size label from a pre-stored label storage structure based on the target coordinate information, the distance value and the target labeling direction includes:
determining a first size labeling set with the original labeling direction consistent with the target labeling direction in a pre-stored labeling storage structure; determining a second dimension marking set in the first dimension marking set, wherein the difference value of the original dimension value and the distance value is within a first error range; and determining the target size label from the second size label set based on the position relation between the target coordinate information and the label starting point and the label end point.
In some embodiments, after obtaining the target coordinate information, the distance value, and the target labeling direction, the target can be filtered from a pre-stored label storage structure based on the parameters. Each dimension label in the label storage structure comprises an original label direction, an original dimension value, a label starting point and a label end point, so that the parameters of the two target picking points can be compared with the storage labels in the label storage structure, and the target dimension labels can be determined.
Specifically, a first size label set which is consistent with a target label direction is firstly screened in the label storage structure by traversing the label storage structure, the first size label set is further screened by the distance value, the size labels with the distance value being as much as the original size value in the size labels in the first size label set are screened out, and a second size label set with the difference value between the original size value and the distance value within a first error range is obtained. And then, determining the target size label from the second size label set according to the position relation between the target coordinate information and the label starting point and the label end point.
When the distance value and the original dimension value are calculated, the distance value and the original dimension value are values on the same scale, and the first error range may be, but is not limited to, from-5 meters to 5 meters, taking the actual distance value calculation of the distance value and the original dimension value as an example.
In an alternative embodiment, the target coordinate information includes a pickup start point coordinate and a pickup end point coordinate;
the determining the target size label from the second size label set based on the position relationship between the target coordinate information and the label starting point and the label end point includes:
determining a third dimension labeling set in which a difference value between the coordinates of the picking start point and the coordinates of the labeling start point in a non-target labeling direction is within a second error range and a difference value between the coordinates of the picking end point and the coordinates of the labeling end point in the non-target labeling direction is within a third error range, wherein the non-target labeling direction is a direction perpendicular to the target labeling direction; sorting the size labels in the third size label set according to the size difference value between the original size value and the distance value; and determining the size label corresponding to the minimum value in the size difference value as the target size label.
In some embodiments, the size value of the size label in the second size label set is within the error tolerance range from the distance value of the two target pick-up points, and the labeling direction is the same as the target labeling direction, so that the size label in the second size label set is different from the two target pick-up points in the non-target labeling direction, so that the target coordinate information is different from the position relationship between the label starting point and the label ending point. When the labeling start point and the labeling end point have a large deviation from the target coordinate information, the corresponding size labels may not be the size labels corresponding to the two pickup points, so that the target coordinate information, the labeling start point and the labeling end point need to satisfy the following matching conditions: and a third dimension marking set, wherein the difference value between the coordinates of the picking start point and the coordinates of the marking start point in the non-target marking direction is within a second error range, and the difference value between the coordinates of the picking end point and the coordinates of the marking end point in the non-target marking direction is within a third error range.
Although there is a certain deviation between the two picked points selected by the user, the user often clicks the edge of the object whose size is desired to be obtained as accurately as possible when selecting the two picked points, and therefore, after the third set of size labels is obtained, the size labels in the set are sorted according to the difference between the original size value and the distance value, and the size label with the smallest difference is taken as the target size label.
In an ideal case, when the pick-up starting point, the pick-up end point, the mark starting point and the mark end point can form a rectangle, or the pick-up starting point coincides with the mark starting point and the pick-up end point coincides with the mark end point, the size mark corresponding to the mark starting point is the target size mark retrieved by the two pick-up points.
The pre-stored label storage structure summarized in the above embodiments may be that all size labels in the drawings are stored in the same file according to the same storage format, and are screened one by one during retrieval. The size labels can be classified and sorted firstly, so that during retrieval, direct screening can be performed according to each type of size labels, and the retrieval efficiency is improved.
In an alternative embodiment, the process of pre-storing the annotation storage structure comprises:
extracting the marking information of the dimension marking graphic elements in the drawing; dividing the dimension marking primitive into at least one group of marking data groups based on the marking information, wherein the dimension marking primitive in each group of marking data groups is not adjacent to the dimension marking primitives in other marking data groups; and storing the labeling information in each group of labeling data groups according to the adjacency relation among the dimension labeling primitives to obtain a labeling storage structure.
In some embodiments, in order to facilitate retrieval of the target dimension labels, the dimension labels in the drawing are stored in a label storage structure, the dimension labels are grouped in the label storage structure, and the dimension labels in each group are structurally stored, so that rapid retrieval is facilitated.
In the process of drawing an actual drawing, when components on a line are marked, size marks are often on the same line. Based on this, for each extracted dimension marking primitive, whether a dimension marking primitive adjacent to the extracted dimension marking primitive exists or not can be judged through marking information, so that the adjacent dimension marking primitives are divided into one group to obtain a plurality of initial groups, and for some dimension marking primitives, two adjacent dimension marking primitives may exist, so that the two adjacent dimension marking primitives exist in the two initial groups.
After the dimension marking primitives are grouped, the dimension marking primitives can be stored according to the adjacency relation based on the marking information in each group, and therefore the marking storage structure is obtained.
In an optional embodiment, the extracting the labeling information of the dimension labeling primitive in the drawing includes:
traversing all the primitives in the drawing, and extracting dimension marking primitives with primitive types as marking types; and extracting the labeling information of the dimension labeling graphics primitive.
In some embodiments, each primitive in the drawing has a primitive type, such as a label type, a component type, a view type, and the like, and by judging the primitive type, the primitive of the label type is extracted, and label information of the primitive of each label type is obtained.
In an optional embodiment, the annotation information includes an annotation start point and an annotation end point, and the dividing the size annotation primitive into at least one group of annotation data groups based on the annotation information includes:
judging whether the labeling information of other dimension labeling primitives comprises the labeling starting point or the labeling end point of the dimension labeling primitive or not for any dimension labeling primitive; if so, determining the dimension marking primitives with the same marking starting point or marking end point as mutually adjacent dimension marking primitives; and determining the mutually adjacent dimension marking primitives as a group of marking data groups.
In some embodiments, the extracted labeling information of the dimension labeling primitives includes a labeling start point and a labeling end point, when two dimension labeling primitives are adjacent, the labeling end point of one dimension labeling primitive coincides with the labeling start point of the other dimension labeling primitive, based on which, whether there is a labeling end point or a labeling start point of any dimension labeling primitive or a labeling end point coincides with the labeling start point or the labeling start point of the other dimension labeling primitive, if so, the two are considered as the adjacent dimension labeling primitives.
In an optional embodiment, the labeling information includes an original size value, a labeling start point and a labeling end point; the step of storing the labeling information in each group of the labeling data groups according to the adjacency relation among the size labeling primitives to obtain a labeling storage structure comprises the following steps:
determining the marking starting point and the marking end point in each marking data group as node information; merging the same node information among the dimension marking primitives with the adjacency relation to obtain a node storage structure; and determining the original size value in each group of labeled data groups as attribute information among the node information in the node storage structure to obtain the labeled storage structure of each group of labeled data groups.
In some embodiments, after determining the adjacency between the dimensioning primitives, an annotation storage structure can be constructed based on the adjacency and the original dimensions in the annotation information. Specifically, the labeling start point and the labeling end point in each group of labeling data groups can be used as node information, and the labeling start point and the labeling end point of the adjacent size labeling graphics primitives can coincide with each other. Therefore, different labeling starting points and labeling end points in each group of labeling data groups are associated to obtain a node storage structure. In addition, the label information also includes an original size value, and in the node storage structure, the label starting point and the label end point represented by two adjacent nodes take the corresponding original size value as the attribute information between the two node information, thereby obtaining the label storage structure.
Illustratively, a plurality of size annotation primitives with annotation starting points and annotation ending points of (V0, V1), (V1, V3), (V3, V4), (V0, V2) and (V2, V3) are included in an annotation data group, so five nodes of V0-V4 are obtained, and the node storage structure can be stored in the manner shown in fig. 3. And correspondingly storing the original size as attribute information between the two nodes to obtain a label storage structure.
For quick retrieval, the label storage structure can be stored in a manner of a contiguous matrix. Specifically, the node information in the labeled data group of each group is stored in a one-dimensional array, and the attribute information between nodes is stored in two-dimensional data, wherein elements in the array represent the attribute information between nodes represented by corresponding rows and columns.
Specifically, the node storage structure shown in fig. 3 may be represented by the adjacency matrix shown in fig. 4.
The size marking primitives in each group of marking data groups are in an adjacent relation, so that the size marking primitives in each group are all on the same line, and when the size marking primitives are stored in a marking storage structure, marking directions can be set for each group of marking data groups so as to be standardized and unified, and later-stage size marking retrieval is facilitated.
In a specific embodiment, the retrieval method for drawing dimension marking performs structured storage processing on dimension marking data, and realizes rapid retrieval processing on dimension marking based on a structured storage design scheme.
The size marking is structured specifically by performing data structuring and storage processing on the cad-analyzed primitive data. The structural design and data storage of drawing dimension marking are realized by extracting marking primitive data, grouping marking primitives, representing and performing structural processing on marking data graphs and the like.
The size labeling quick query scheme is specifically based on a size labeling structural design and a data storage scheme, storage processing is carried out by adopting a 'graph grouping' and 'adjacency matrix' structure according to distribution characteristics of drawing labeling data, and quick query of size labeling is promoted through preposed grouping coordinate filtering.
Specifically, the size labeling primitive extraction, grouping by line (line), and graph structured storage processing specifically include:
firstly, extracting and processing a dimension marking primitive according to the picture frame primitive data and the dimension marking type.
And secondly, carrying out independent and non-independent marking division on the dimension marking primitive according to whether the adjacent marking exists or not.
Thirdly, traversing the non-independent dimension labels, acquiring adjacent label data of all the non-independent dimension labels, performing primary grouping, and dividing dimension label primitives with consistent label starting points and label end points into the same group.
And fourthly, according to the non-independent marking grouping and the neighbor marking data thereof, grouping and merging are carried out by judging whether intersecting marks exist. The intersection of the two groups of marking data means that the two groups of marking data have a common size marking primitive.
And fifthly, traversing the grouped data, and storing each group of labeled data according to a graph structure represented by the adjacency matrix.
Specifically, the fast query processing of the size labeling data includes:
firstly, the coordinates of two input points (namely two target picking points) are sorted, the coordinates in the y-axis direction (vertical x-axis) are sequentially returned from bottom to top, and otherwise, the coordinates are sequentially returned from left to right.
And secondly, correcting the two sorted points according to the labeling direction (namely the target labeling direction).
Thirdly, traversing the grouped graph structure data according to the corrected data, and extracting possible target graph structure data. The labeling direction of the obtained target graph structure data is consistent with the target labeling direction, and the coordinates of the two corrected points are in the vertex range of the graph structure data.
And fourthly, traversing possible target graph structure data, and acquiring matched dimension labeling graph structure data according to matching conditions with equal distance and vertical (rectangular) distance.
Fifthly, effective size marking data are obtained by filtering the text marking data. The content of the labels in some dimensioning schemes may be such that the designer fills out the text string in addition to the numbers, and therefore filtering of the text label data is required.
And sixthly, sorting the effective size marking data to obtain the size marking with the best matching.
