Description

Method, device, equipment and medium for measuring interval thickness of three-dimensional model
Technical Field
The present invention relates to the field of measurement technologies, and in particular, to a method, an apparatus, a device, and a medium for measuring a three-dimensional model interval thickness.
Background
In the field of manufacturing industry, it is generally required to design a three-dimensional model using three-dimensional design software UG (Unigraphics NX, digital product development system), and process and manufacture a blank based on the three-dimensional model, to process the blank into a finished product.
In some cases, in order to reduce the machining cost, machining is performed by a machining method with a low precision, and when the thickness of the space between two surfaces to be machined in the three-dimensional model is too low, machining and manufacturing anomalies are likely to occur. As shown in fig. 4, in the case where two identical holes are drilled in the same direction with a relatively small interval, when the interval thickness between the two holes is less than a certain degree, the drilling accuracy for machining is low, and it may be shifted from the center during the drilling; since the larger the depth is, the larger the offset center is, when the depth of the two holes is larger, the two holes may intersect at the bottom, that is, a hole breakage problem may occur, resulting in abnormal manufacturing.
Since the three-dimensional model is the basis of the final processing and manufacturing finished product, if a place where the interval thickness is lower than a preset minimum value can be found in advance in the three-dimensional model and modified, the processing and manufacturing abnormality can be reduced, thereby reducing the processing and manufacturing cost. However, the prior art can only measure the thickness of each interval in the model by a common measurement algorithm carried by the UG software. However, because the thickness of the space to be measured in a model is typically too large, it can be as high as thousands of times; however, manually measuring each spacer thickness is not only time-consuming and easy to miss, so how to measure spacer thickness in a model body efficiently and accurately is a technical problem to be solved by those skilled in the art.

Detailed Description
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. The percentages not specifically stated in the present invention are weight percentages/mass percentages.
Referring to fig. 1-10, there is shown a flowchart of steps of an embodiment of a method of measuring the thickness of a three-dimensional model interval according to the present invention, which may include the steps of:
obtaining an identifier in the model body; wherein the identifier comprises a wired identifier and a face identifier;
acquiring a first non-adjacent facing set A in the model body according to the identifier; wherein any one of the non-adjacent pairs of faces a in the first non-adjacent pair of faces set a has a pair-face relationship G, the pair-face relationship G comprising:
the safety distance value q between the faces is not greater than the minimum distance value k1 of the interval thickness;
the common edge does not exist between the faces;
the area of any one surface is not smaller than a preset minimum value k2 of the area;
and acquiring all non-adjacent facing surfaces B with interval thickness meeting preset conditions from the first non-adjacent facing surface set A as a second non-adjacent facing surface set B. More specifically, to reduce the number of measurement processes of conventional common measurement algorithms, it is desirable to use a combined contrast process to eliminate a large number of opposing faces that do not require measurement. In the present embodiment, the combined contrast processing includes an over-distance elimination processing, an adjacent surface elimination processing, and an over-facet elimination processing, which can eliminate three types of paired surfaces, respectively: a finished surface having a too large surface-to-surface distance; a forming surface with a common edge exists between the surfaces; there is a pair of facets with an area that is too small, and because facets are negligible, measurement of the gap thickness is not required. In order to improve the execution efficiency, the order of the combination contrast processing is not generally changed, that is, the process of eliminating the distance is performed first, then the process of eliminating the adjacent surface is performed, and finally the algorithm of eliminating the small surface is performed. After the comparison processing is carried out in the model body, a first non-adjacent facing surface set A is obtained; the common measurement process is then performed on each non-adjacent pair a contained in the first set of non-adjacent pairs a, and a non-adjacent pair b is derived. The preset condition is that the distance between the non-adjacent facing surfaces a is smaller than a minimum distance k1, that is, when the distance between the surfaces in the non-adjacent facing surfaces a is smaller than the minimum distance k1, machining errors are likely to occur, and in this case, a technician can adjust and modify the non-adjacent facing surfaces b according to the obtained non-adjacent facing surfaces b. The preset conditions herein are understood to be preset conditions in the normal measurement process. The UG software is provided with a common measurement processing function, and the distance between two surfaces in the model body can be measured through the interface and the common measurement processing function. In the present embodiment, two faces of the three-dimensional model to be subjected to measurement processing are referred to as facing faces. By measuring the thickness of the space between the two faces in this solution, as can be seen from fig. 4, it is also understood that the spacing between two nearest neighbors is measured in the same face.
It should be noted that, the line identifier corresponds to a line attribute feature of a corresponding line segment, and the line attribute feature includes: the length of each line segment; the face identifier corresponds to a face attribute feature of the corresponding face, the face attribute feature comprising: the number of the faces, the minimum three-dimensional wire frame corresponding to each face, the line segments forming the faces corresponding to each face, the area value of each face and the like. After the line identifier and the face identifier are acquired, the corresponding line attribute and face attribute can be acquired through an interface in the UG software.
It should also be noted that in UG software, each model body, each face, and each line has only one unique identifier, which can be used to uniquely name and distinguish each model body, each face, and each line; it is further noted that, because the identifiers of each body, each face, each line and each point in the UG software are independent of each other, although the model body and its corresponding upper line point are associated, if the identifier of the upper line point in the model body is to be obtained, the corresponding upper line point identifier in the model body can be obtained through the interface of the UG software.
According to the embodiment of the application, the paired surfaces in the model body are subjected to combined comparison treatment before the common measurement treatment, so that paired surfaces which are too far apart and are paired surfaces of adjacent surfaces or the same surface and too small in area can be effectively removed, excessive surfaces can be detected when the common measurement algorithm treatment is performed, the treatment time of the common measurement treatment is greatly reduced, and the efficiency of modifying the distance between paired surfaces with too small interval thickness is improved.
Next, a method of measuring the space thickness of the three-dimensional model in the present exemplary embodiment will be further described.
As an example, the step of obtaining a first non-adjacent set of pairs a in the model body from the line identifier and the face identifier comprises:
s1: any one surface of the model body is obtained to serve as a reference surface, and the reference surface is marked as an ith reference surface; acquiring any surface of the model body, which is subjected to comparison processing with the ith reference surface, as a comparison surface, and marking the comparison surface as the jth comparison surface;
s2: according to the ith reference plane and the jth comparison plane, executing the steps of removing the excessive distance processing, removing the adjacent plane processing and removing the excessive facet processing; if the ith reference surface and the jth comparison surface meet the requirement of the paired surface relation G, obtaining a corresponding non-adjacent paired surface a;
s3: judging whether the model body has an unparallel surface or not; if yes, returning to the execution step S1; if not, entering step S4;
s4: and summarizing all the obtained non-adjacent facing surfaces a to form a first non-adjacent facing surface set A, and terminating traversal. More specifically, the unpaired face refers to a reference face in the model body that has not been selected for comparison processing, and a comparison face in the model body that has not been selected for comparison processing with the i-th reference face. In this embodiment, one surface is selected as the i-th reference surface in the model body, and then one surface subjected to comparison processing with the i-th reference surface is selected as the j-th comparison surface in the model body. Therefore, the j-th reference plane here is likely to be identical to the i-th reference plane, since they are all selected in the model body. Taking the ith reference surface as a reference, and carrying out contrast treatment on all contrast surfaces in the model body with the ith reference surface one by one, wherein the contrast treatment is distance elimination treatment, adjacent surface elimination treatment and facet elimination treatment; when the ith reference plane and a comparison plane meet the pairing relation G, the ith reference plane and the comparison plane are a group of non-adjacent pairing planes a; when the ith reference surface and one comparison surface do not meet the pairing relation G, a step S3 is entered, at this moment, whether all the comparison surfaces and the ith reference surface are subjected to comparison processing is judged first, if not, the step S1 is returned to, and the comparison processing is carried out between the other comparison surface and the current ith reference surface, so that the comparison surface at this moment can be marked as a j+1th comparison surface for the convenience of understanding; if all the reference surfaces are compared with the ith reference surface, then judging whether all the reference surfaces are selected. If it is determined that there is a surface which is not selected as the reference surface, the surface is acquired as the reference surface for the next comparison processing, and for convenience of understanding, it can be understood that the reference surface at this time is the i+1th reference surface. If there are no faces that are not selected as reference faces, all the non-adjacent pairs a obtained can be summarized to form the first non-adjacent pair set a. Taking this embodiment as an example, there are 6 surfaces in a certain model body, and any one of the surfaces is obtained as a reference surface, and is recorded as a 1 st reference surface, and there are 6 reference surfaces (a 1 st reference surface, a 2 nd reference surface, a 3 rd reference surface, a 4 th reference surface, a 5 th reference surface, and a 6 th reference surface) at this time; and then, any surface of the model body is taken as a comparison surface, and the comparison surface is marked as a 1 st comparison surface, and 6 comparison surfaces (a 1 st comparison surface, a 2 nd comparison surface, a 3 rd comparison surface, a 4 th comparison surface, a 5 th comparison surface and a 6 th comparison surface) are also obtained. And then the 6 comparison surfaces are respectively compared with the 1 st reference surface, if the 1 st reference surface and the 1 st comparison surface accord with the pairing relation G, the comparison surfaces are marked as a group of non-adjacent pairing surfaces a, then the comparison surfaces enter into S3 to judge whether the comparison surfaces are used up, and when the 1 st comparison surface is found to be compared, the 2 nd comparison surface is obtained to be compared with the 1 st reference surface. Even if the 1 st reference plane and the 1 st comparison plane do not match the pairing relation G, the process goes to S3 to determine whether the comparison plane is used up. When judging that the 1 st reference surface is used up with the 6 th reference surface after the comparison processing is carried out, namely, when the comparison surface which is used up with the 1 st reference surface is used up, judging whether the reference surface is used up or not, and when the 1 st reference surface is compared at the moment, changing the reference surface into the 2 nd reference surface and then carrying out the comparison processing, namely, carrying out one-to-one comparison processing with the 6 comparison surfaces by using the 2 nd reference surface.
As an example, in the step of performing the distance-elimination excessive processing, the adjacent-surface-elimination processing, and the facet-elimination excessive processing according to the i-th reference surface and all the j-th reference surfaces, the distance-elimination excessive processing specifically includes:
c1: acquiring a minimum three-dimensional wire frame xi of the ith reference plane through the plane identifier of the ith reference plane, and acquiring a diagonal length r1 of the minimum three-dimensional wire frame xi;
c2: acquiring a minimum three-dimensional wire frame xj of the jth comparison surface through a surface identifier of the jth comparison surface, and acquiring a diagonal length j1 of the minimum three-dimensional wire frame xj;
and C3: obtaining the length d3 of a connecting line of a diagonal central point between the minimum three-dimensional wire frame xi and the minimum three-dimensional wire frame xj;
and C4: judging whether the safety distance value q is larger than the minimum distance value k1, wherein q=d3-r 1/2-j1/2; if yes, entering a step S3; if not, entering a step C5;
c5: and outputting the ith reference plane and the jth comparison plane as a first temporary group z1. More specifically, the minimum three-dimensional wire frame is automatically generated by UG software, and each surface can be enclosed by a minimum three-dimensional wire frame, and it should be noted that when two surfaces are identical in space, the minimum three-dimensional wire frame is identical; but the minor three-dimensional wireframes are identical, the non-substituted surfaces are spatially identical. As shown in fig. 9, the diagonal length r1 of the minimum three-dimensional wire frame xi is the length of the wire segment A1A2, the wire segment A1A3 can be understood as a radius (with a value of r 1/2), the diagonal length j1 of the minimum three-dimensional wire frame xj is the length of the wire segment B1B2, the wire segment B1B3 can be understood as a radius (with a value of j 1/2), and the connecting wire segment between the wire segment A1A2 and the midpoint of the wire segment B1B2 is A3B3 (with a value of d 3); when the connecting line segment d3 subtracts r1/2 and j1/2 respectively, a safety distance q is left; if the safety distance q is greater than k1 (k 1 is the minimum distance value of the spacing thickness set by the user), it is indicated that the distance between the surface a and the surface B cannot be lower than k1, that is, the spacing thickness of the non-adjacent pairs of surfaces is not too small; if the safety distance q is not greater than k1, then the subsequent comparison is performed based on this condition. In fig. 6, the start step is started on the premise that the i-th reference plane and the j-th reference plane are acquired, that is, on the premise that step S1 is performed, and when it is determined that the safe distance value q is greater than the minimum distance value k1, the end means the end of this step for the distance elimination process, and the next step proceeds to step S3.
As an example, in the step of performing the distance elimination process, the adjacent surface elimination process, and the facet elimination process based on the i-th reference surface and all the j-th reference surfaces, the adjacent surface elimination process specifically includes:
d1: acquiring a line identifier of the ith reference plane in the first temporary group z 1;
d2: screening out a common edge surface with any line identifier of the ith reference surface in the model body, and acquiring the identifier of the common edge surface;
d3: determining whether the identifier of the j-th reference plane in the first temporary group z1 is identical to the identifier of any one of the co-boundary planes; if yes, entering a step S3; if not, entering a step D4;
d4: and outputting the ith reference plane and the jth comparison plane in the first temporary group z1 as a second temporary group z2. More specifically, since the jth surface may be identical to or adjacent to the ith surface, where identical refers to the same surface case, and adjacent may refer to the case where two surfaces have a common edge, the minimum distance between the two surfaces is 0 in both cases, and the surfaces in both cases need to be excluded. Since the i-th surface and the j-th surface are both surfaces in the model body, the i-th surface and the j-th surface may be the same surface, and thus, not only surfaces having a common edge may be removed by excluding the adjacent surface treatment; and when the ith surface and the jth surface are the same surface, the ith surface and the jth surface can be selected and removed. It should be noted that, in the present embodiment, the starting step in fig. 7 is started on the premise that the first temporary group z1 is acquired, that is, on the premise that step C5 is performed; when it is determined that the identifier of the j-th reference plane is the same as the identifier of any common plane, the end refers to the end of this step for excluding the adjacent plane, and the next step proceeds to step S3.
As an example, in the step of performing the distance elimination excessive processing, the adjacent surface elimination processing, and the over-facet elimination processing according to the i-th reference surface and all the j-th reference surfaces, the over-facet elimination processing specifically includes:
e1: in the second temporary group z2, acquiring an area value mj of the jth comparison surface through the surface identifier of the jth comparison surface;
e2: judging whether the area value mj is smaller than a preset minimum value k2 of the area or not; if yes, returning to the step S3; if not, entering a step E3;
e3: outputting the ith reference plane and the jth comparison plane in the second temporary group z2 as a group of the non-adjacent opposite planes a. More specifically, k2 is a minimum area value set by the user, and when the area of the jth comparison surface is smaller than k2, this indicates that this comparison surface is too small, and the measurement interval thickness is meaningless, so this surface can be ignored. It should be noted that, in the present embodiment, the starting step in fig. 8 is started on the premise that the second temporary group z2 is acquired, that is, on the premise that step D4 is performed; when it is determined that the area value mj is smaller than the preset minimum value k2 of the area, the end refers to the end of this step for the process of excluding the undersides, and the next step goes to step S3. The interface of UG software is used for obtaining the line identifier and the surface identifier of the co-edge surface and the j-th contrast surface, and the line attribute characteristics and the surface attribute characteristics corresponding to the line identifier and the surface identifier are respectively read through the line identifier and the surface identifier. The attributes of the lines comprise the number, the length and the like of all the lines, and the attributes of the planes comprise the number of all the planes, the corresponding minimum three-dimensional wire frame, the area value and the like.

As an example, the step of obtaining, as the second non-adjacent pair face set B, all non-adjacent pair faces B whose interval thickness satisfies the preset condition in the first non-adjacent pair face set a includes:
f1: in a first non-adjacent opposite face set A, any group of non-adjacent opposite faces a are acquired;
f2: a step of executing ordinary measurement processing according to the ith reference plane and the jth comparison plane corresponding to each other in the non-adjacent pair of planes a; if the ith reference surface and the jth comparison surface meet the requirement of the interval thickness, obtaining a corresponding non-adjacent forming surface b;
f3: judging whether the non-adjacent facing surface a which is not subjected to common measurement processing exists in a first non-adjacent facing surface set A or not; if yes, returning to the execution step F1; if not, go to step F4

It should be noted that, in this embodiment, the initial step in fig. 10 is started on the premise that the first non-adjacent pair-face set a is acquired, that is, on the premise that the combined comparison processing step is completed; and when judging that the first non-adjacent paired surface set A has no non-adjacent paired surface a which is not subjected to common measurement processing, summarizing the obtained non-adjacent paired surfaces B to obtain a second non-adjacent paired surface set B, and ending the flow.
