Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic flow diagram of a method for determining device installation parameters according to an embodiment of the present application, where the present embodiment is applicable to any scenario where installation parameters need to be determined when an apparatus to be installed is installed, and the method may be executed by an apparatus for determining device installation parameters, where the apparatus may be implemented in a hardware and/or software manner, and may be generally integrated in an electronic device such as a computer with data computation capability, and specifically includes the following steps:
In this step, the device to be installed refers to a device that needs to be installed, such as a valve, a pipeline, a fan, and the like. The preset standard legend may be a standardized graphic block preset for the device to be installed, and in order to facilitate subsequent comparison of installation legends for different zoom degrees, in this embodiment, the preset standard legend may be set as a vector graphic block.
In addition, the installation legend in this step refers to the corresponding block in the installation drawing to be referred to when actually installing the device to be installed.
It should be noted that the preset standard legend may be stored in the example library, and during storage, mapping storage may be performed on the identifier of the device to be installed, where the identifier of the device to be installed is unique, so that the preset standard legend may be queried from the example library through the identifier of the device to be installed.
Similarly, in the aforementioned installation drawing, the image blocks corresponding to different devices may be mapped with the identifiers of the devices, and when the installation legend corresponding to the device to be installed is obtained from the installation drawing, the image block corresponding to the identifier of the device to be installed is directly extracted and used as the installation legend corresponding to the device to be installed.
Because the installation drawing may have a plurality of devices to be installed at different installation positions, at this time, the devices to be installed in the installation drawing can be numbered in advance, the numbers and the identifiers are combined into a new identifier, and the step only needs to acquire the installation legend of the devices to be installed from the installation drawing according to the new identifier.
In a specific example, fig. 2 and fig. 3 may be referred to, where fig. 2 is a schematic diagram of an installation illustration of a device to be installed according to an embodiment of the present application, and fig. 3 is a schematic diagram of a preset standard illustration of a device to be installed according to an embodiment of the present application.
As shown in fig. 2 and 3, the installation legend corresponding to the device to be installed may be a "z" -shaped component shown in fig. 2, and the obtained preset standard legend may be a "z" -shaped component shown in fig. 3.
And 102, performing geometric transformation on a preset standard legend for preset times, and acquiring legend parameters of a transformation legend obtained after each geometric transformation.
In this step, a predetermined number of times of geometric transformations are performed on a predetermined standard legend, each geometric transformation obtains a transformation legend, and each transformation legend corresponds to a set of legend parameters.
In the solution of this embodiment, the geometric transformation may refer to different transformation manners such as rotation and mirror image, and in actual installation, the difference between the installation legend and the standard legend is often that there is a difference in rotation angle, or that the installation legend and the standard legend are mirror images of each other.
Therefore, in order to facilitate determining the difference between the installation legend and the standard legend, the present embodiment performs multiple geometric transformations on the preset standard legend, and transforms the preset standard legend into different position states, so as to perform similarity comparison with the installation legend.
Specifically, referring to fig. 4, fig. 4 is a schematic flow chart of a legend parameter for obtaining a conversion legend according to an embodiment of the present application.
As shown in fig. 4, in this embodiment, the process of obtaining the legend parameter of the conversion legend may include:
In the foregoing, it is mentioned that the preset standard legend is a vector graphic block, and therefore, the main feature points thereof are vector coordinate points, generally, the vector coordinate points of the preset standard legend can be directly integrated in the information of the legend as the feature points of the legend, and in this step, the corresponding vector coordinate points are directly extracted from the information of the legend as the first vector coordinate set.
Because the draftsman drawing the installation legend may have different drafting styles, such as for the graph shown in FIG. 2, some draftsman may draw with line segments, some may draw with multi-line segments, and some may even draw with a combination of both.
Taking CAD drawing software as an example, a line segment has two end points, and when the graph of the graph 2 is drawn by using the line segment, 6 end points exist, namely 6 vector coordinate points correspond to the end points; by using multiple line segments to plot the graph of fig. 2, there are only two coordinate points, two line segment inflection points, i.e., 4 vector coordinate points.
If the number of coordinate points included in the first vector coordinate set corresponding to the preset standard legend is less than the number of coordinate points corresponding to the installation legend, certain interference may occur during subsequent similarity comparison, resulting in inaccurate similarity comparison.
Therefore, in this step, the first vector coordinate group may be acquired on the basis of the rule that the coordinate points of the installation legend are covered by the maximum amount. Specifically, referring to fig. 5, fig. 5 is a schematic flowchart for determining a first vector coordinate set according to an embodiment of the present application.
As shown in fig. 5, the process of determining the first vector coordinate set provided by this embodiment may include:
It should be noted that, the process of acquiring the coordinate point in this step may refer to the foregoing description of step 401, and is not described herein again.
And 502, repeatedly collecting intermediate coordinate points except the coordinate points corresponding to the head end point and the tail end point in the coordinate points to obtain repeated intermediate coordinate points.
In this step, the intermediate coordinate points except the coordinate points corresponding to the head and tail end points in the coordinate points are repeatedly collected, so that the obtained coordinate points can be ensured to cover the coordinate points of the installation legend to the maximum extent.
Since the drawing habit is mainly the difference between a line segment and a multi-line segment, the present embodiment is mainly optimized for the habit. In a specific example, reference may be made to fig. 6, where fig. 6 is a schematic diagram of a preset standard legend with coordinate points provided in an embodiment of the present application.
As shown in fig. 6, (x1, y1) and (x4, y4) are coordinate points corresponding to the head-tail end points, (x2, y2) and (x3, y3) are intermediate coordinate points, and (x5, y5) and (x6, y6) are repeated intermediate coordinate points.
In addition, in this step, when determining the first minimum bounding volume covering all vector coordinates in the first vector coordinate set, the first vector coordinate set may be first converted into a coordinate matrix, and then the coordinate matrix is input into a preset minimum bounding volume obtaining function, so as to obtain the first minimum bounding volume output by the minimum bounding volume obtaining function.
It should be noted that the transformation coordinate matrix may be implemented by using a numpy function, and taking the coordinate points shown in fig. 6 as an example, a specific example of the transformation coordinate matrix may be symMat ═ np.array ([ (x1, y1), (x2, y2), (x5, y5), (x3, y3), (x6, y6), (x4, y4) ], and dtype ═ np.float 32.
In addition, the minimum bounding graph obtaining function may be an openCV function, and the principle of obtaining the minimum bounding graph by using the openCV function may refer to a related technology applying the openCV function, which is not described herein again.
It should be noted that the first minimum enclosing pattern is rectangular or circular, and in the present embodiment, a rectangular form is adopted in order to make the geometric transformation more friendly.
Further, after the first minimum enclosing pattern is rotated into a regular rectangle, the subsequent step 402 is performed, where the regular rectangle is that one side of the rectangle is parallel to one axis of the coordinate system, and specifically, an included angle between a target side of the first minimum enclosing pattern and a first coordinate axis of the coordinate system may be determined first; and then, rotating the first minimum enclosing graph according to the included angle so as to enable the target edge to be parallel to the first coordinate axis, and then executing the step of performing geometric transformation on the first minimum enclosing graph for preset times on the basis of the rotated first minimum enclosing graph.
The target edge may be any one edge of the first minimum bounding rectangle, and may generally refer to the length of the rectangle, the first coordinate axis is any one axis of a coordinate system, and the coordinate system is a rectangular coordinate system.
After the first minimum enclosing graph is rotated into the positive rectangle, the subsequent geometric transformation is more visual and convenient, and the calculated amount is less.
Of course, in order to make the calculation more friendly, the center point of the first minimum bounding graph may be set as the origin of the coordinate system, and then the vector coordinates in the first vector coordinate set may be transformed according to the graph parameters (the length, width, and original center point coordinates of the rectangle) of the first minimum bounding graph. On the basis, the rectangular plate is rotated into a positive rectangle.
In order to reduce the calculation power consumed in the process of rotating into the regular rectangle, in this embodiment, the minimum angle required to rotate into the regular rectangle can be calculated according to the obtained included angle, for example, the included angle is 60 degrees, and then the first minimum enclosing image can be rotated counterclockwise by 30 degrees to form the regular rectangle; with an included angle of 20 degrees, the first minimal enclosing image can be rotated clockwise by 20 degrees to form a positive rectangle.
After the rotation into a regular rectangle, new coordinates of each vector coordinate point in the first vector coordinate points can be calculated according to the vector coordinates obtained after the central point is transferred and the minimum angle. The specific calculation process may refer to a related mathematical algorithm of coordinate transformation, which is not described herein again.
In this step, the more times of geometric transformation, the more accurate the finally determined installation parameters, and in combination with the actual installation situation, generally, the rotation angles of the deviation between the installation legend and the installation legend are usually 0 degree, 90 degree, 180 degree, 270 degree and the mirrored 0 degree, 90 degree, 180 degree, 270 degree, relative to the preset standard legend, so the geometric transformation of the preset times in this step may be 0 degree, 90 degree, 180 degree, 270 degree rotation and the mirrored 0 degree, 90 degree, 180 degree, 270 degree rotation, which are 8 kinds of geometric transformation.
Since the comparison subject is the vector coordinate point of the legend during the final similarity comparison, it is necessary to move all the vector coordinates in the first vector coordinate set covered by the first minimum bounding graph during each geometric transformation.
And step 403, for any geometric transformation, obtaining the legend parameters of the transformation legend obtained by the current geometric transformation according to the first minimum bounding figure after the geometric transformation and the first vector coordinate group after the movement.
In this step, the legend parameter is mainly the number of coordinate points included in each area in the coordinate system, and in a specific example, the legend parameter may include: the number of coordinate points in the positive y-axis region, the number of coordinate points in the negative x-axis region, the number of coordinate points in the positive x-axis region, the number of coordinate points in the negative x-axis region, the positive y-axis region, the number of coordinate points in the positive x-axis region, the positive y-axis region, the number of coordinate points in the negative x-axis region, the negative y-axis region, the number of coordinate points in the positive y-axis region, the number of coordinate points in the negative x-axis region, the number of coordinate points in the positive y-axis region, the number of coordinate points in the negative x-axis region, the number of coordinate points in the positive x-axis region, the negative y-axis region, the first minimum aspect ratio, Rotation angle, y-axis mirror value (no mirror is 1, mirror is-1).
In a specific example, please refer to fig. 7, fig. 7 is a schematic diagram illustrating a center point as an origin and a first minimum bounding graph as a regular rectangle according to an embodiment of the present application.
As shown in fig. 7, in the state of 0 degree rotation (first geometric transformation), the number of coordinate points in the positive y-axis region is 3 (x2, y2), (x5, y5), (x4, y4)), and the number of coordinate points in the negative y-axis region is 3, … …, and the rotation angle is 0+ minimum angle (the minimum angle obtained when the rotation is a positive rectangle).
After the counter-clockwise rotation is carried out for 90 degrees (for the second time), the rotation angle is 90+ the minimum angle, and the number of the coordinate points of each area can be directly assigned. For example, the number of coordinate points in the positive y-axis region at this time is the number of coordinate points in the positive x-axis region at the previous time.
And 103, acquiring legend parameters of the installation legend, and determining a target conversion legend with the maximum similarity to the installation legend from all conversion legends according to the legend parameters of the installation legend and the legend parameters of the conversion legend.
In this step, the legend parameter of the installation legend may refer to the aforementioned process of obtaining the legend parameter of the conversion legend, extract a second vector coordinate set of the device to be installed from the installation legend, and determine a second minimum bounding graph covering all vector coordinates in the second vector coordinate set; and acquiring the legend parameters of the installation legend according to the second minimum bounding graph and the second vector coordinate set. And will not be described in detail herein.
It should be noted that, if the center point of the first minimum bounding rectangle is moved and rotated to be the positive rectangle, the center point of the second minimum bounding rectangle is also moved and rotated to be the positive rectangle in this step.
In addition, the rotation angle in the legend parameter of the second smallest bounding rectangle is the minimum angle required to rotate it into a positive rectangle.
Referring to fig. 8, in the process of determining the target transformation legend in this step, fig. 8 is a schematic flowchart of determining the target transformation legend according to an embodiment of the present application.
As shown in fig. 8, the process of determining the target transformation legend may include:
Since the legend parameters include a plurality of parameters, in this step, the ratio may be obtained in a one-to-one correspondence manner, and then the ratio is added to obtain the ratio between the legend parameters and the legend parameters finally obtained in this step.
And step 802, determining the conversion legend corresponding to the ratio closest to the preset threshold as the target conversion legend with the maximum similarity to the installation legend.
It should be noted that, the more similar the conversion legend and the installation legend, the closer the ratio of a legend parameter is to 1, and the aforementioned process is to add the ratios, so the preset threshold in this step can be the parameter number of the legend parameter.
Still taking the example of the illustrated parameters mentioned in the previous embodiment as an example, there are 20 parameters, and the preset threshold in this step is 20. And the closest to the preset threshold may be quantified as the absolute value of the difference between the ratio and the preset threshold being the smallest.
And step 104, determining the installation parameters of the equipment to be installed according to the legend parameters of the target conversion legend and the legend parameters of the installation legend.
In this step, the legend parameters include a rotation angle parameter, i.e., the aforementioned rotation angle, and a mirror image parameter, i.e., the aforementioned y-axis mirror image value. Specifically, the difference between the rotation angle parameter corresponding to the target conversion legend and the rotation angle parameter corresponding to the installation legend may be determined as the installation angle for installing the device to be installed; determining the mirror image parameters corresponding to the target conversion legend as mirror image installation reference values for installing equipment to be installed; and finally, determining the installation angle and the mirror image installation reference value as the installation parameters of the equipment to be installed.
It should be noted that, when the installation angle is to install the device to be installed, the installation angle needs to be rotated based on the angle in the preset standard legend, and the mirror image installation reference value is "1" to indicate that mirror image installation is not needed, and "— 1" to indicate that mirror image installation is needed.
The technical scheme that this embodiment provided, through introducing the preset standard legend of waiting to install the equipment, through carrying out many times geometric transformation to preset standard legend, thereby obtain a plurality of transformation legends, then confirm the target transformation legend that has the biggest similarity with the installation legend, utilize the legend parameter of target transformation legend and the legend parameter of installation legend to confirm the installation parameters of waiting to install the equipment, the process of obtaining installation parameters through manual measurement has been avoided, the problem that the installation parameters that manual measurement exists obtain inaccurately is solved, realize the effect of the automatic acquisition of more accurate installation parameters.
