Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
As described in the foregoing background, the use of Revit modeling results in a sporadic fractional numerical error like "0.1" or "1" in the relative position between model components or in the absolute position between project basepoints due to software auto-capture misalignment or manual operator error. The error can not be quickly discriminated during modeling, when the number of components is large, the error is accumulated more and more, and the model precision is also poor more and more.
In the prior art, when the problem of the scattered small numerical errors is solved, the dimension labels of the components are simulated by lines and numbers mainly by making false labels, but because the labeled numerical values are not associated with the Revit components, the model components needing to eliminate the errors need to be manually searched, and then the errors are sequentially eliminated by a manual modification mode, namely, the positions of the model components are adjusted by the manual modification mode. Therefore, the existing error elimination mode aiming at the model member in the building information model needs manual elimination, the mode of manually searching and modifying the error is time-consuming and labor-consuming, and the mode does not accord with the forward design flow of drawing after drawing in the building information model and drawing consistency, and the existing error elimination mode aiming at the model member can not really eliminate the position error of the model member.
In view of the above problems in the prior art, it is desirable to provide a model component error elimination scheme that can automatically eliminate the position error of a model component in a building information model, does not need to manually find and eliminate the position error, and can correct the absolute position of the model component to truly eliminate all scattered decimal errors generated during modeling. The implementation process and principle of the technical solution of the present application are described below with reference to the accompanying drawings and specific embodiments, and fig. 1 is a schematic flow chart of an error elimination method for a model component according to the embodiments of the present application. The error elimination method of the model member of fig. 1 may be performed by building information model software or separately developed software, and as shown in fig. 1, the error elimination method of the model member may specifically include:
s101, determining a building information model for executing error elimination operation of a model component, and acquiring the model component in the building information model by using a filter provided by an interface of a preset building information model;
s102, acquiring the position of a positioning point or a positioning line endpoint corresponding to each model component by using an interface of the building information model, wherein the position of the positioning point or the positioning line endpoint is used for representing the absolute coordinate of the model component in the building information model relative to a base point;
s103, determining the distance error of each model component relative to the base point based on the positions of the positioning points or the end points of the positioning lines and the positions of the base points, and judging the distance errors by utilizing preset tolerance values;
s104, when the distance error is larger than the tolerance value, obtaining the coordinates of the positioning point of the model component or the end point of the positioning line when the distance error is larger than the tolerance value, and determining the offset corresponding to the model component when the distance error is larger than the tolerance value by using a preset offset value algorithm;
and S105, adjusting the coordinates of the positioning points or the end points of the positioning lines of the model component when the positioning points or the end points of the positioning lines are larger than the tolerance value according to the offset, so that the absolute position of the model component relative to the base point when the positioning points or the end points of the positioning lines are larger than the tolerance value is changed into an integer.
Specifically, the Building Information model in the embodiment of the present application may adopt a model based on a forward design of a BIM (Building Information Modeling), which is referred to as a Building Information model for short, where the BIM refers to a process of creating and managing Building Information in a whole life cycle of planning, designing, constructing, and operating and maintaining stages of a construction project and a facility, and the whole process applies a three-dimensional, real-time, and dynamic model to cover geometric Information, spatial Information, geographic Information, property Information of various Building components, and work material Information. In BIM, revit is a mainstream BIM visualization and modeling tool, and therefore, the building information model in the embodiment of the present application may adopt a Revit model.
Further, the tolerance value of the embodiment of the present application may be regarded as a range that allows a distance error of the model member with respect to the base point, and a smaller tolerance value may have a higher requirement on the accuracy of the position of the model member in the building information model, and a larger tolerance value may have a lower requirement on the accuracy of the position of the model member in the building information model; in practical applications, a certain tolerance may be set according to actual requirements, for example, the tolerance may be set to the following values: 5mm, 10mm, 20mm, etc. It will be appreciated that the smaller the set tolerance value, the smaller the allowed distance error of the model component with respect to the base point, the greater the number of model components that need to be position corrected, and thus the smaller the tolerance value, the greater the computational complexity.
In some embodiments, obtaining model members in the building information model using a filter provided by an interface of a preset building information model includes: and filtering the instances in the file corresponding to the building information model according to the type of the preset model component by using a filter provided by an API (application program interface) of the building information model to obtain the instances corresponding to the model components conforming to the type in the building information model.
Specifically, the building information model may adopt a Revit model, at this time, an API interface of the building information model may be regarded as a Revit API, and through a filter provided by the Revit API, instances in a file (such as a Revit model file) of the building information model are filtered to obtain an instance corresponding to a model component conforming to a preset type. The instance is an object corresponding to the model component in the file of the building information model, and the instance includes the content such as the attribute information and the position information corresponding to the model component.
In some embodiments, the obtaining the position of the positioning point or the positioning line end point corresponding to each model component by using the interface of the building information model comprises: acquiring absolute coordinates of a positioning point or a positioning line end point corresponding to an instance of each model component from a file of the building information model by using an API (application program interface) interface of the building information model, and taking the absolute coordinates of the positioning point or the positioning line end point as the absolute position of the model component in the building information model; and the positioning points or the positioning line end points are used for positioning the model members in the building information model.
Specifically, each model component in the building information model is located by a positioning point or a positioning line, so that the absolute coordinates of the positioning point or the positioning line endpoint corresponding to each example of the model component can be obtained from the Revit model file by using the method provided by the Revit API. Therefore, the absolute coordinates of the positioning point or the positioning line end point corresponding to the instance of each model component are obtained through the Revit API, so that the absolute position of each model component in the building information model can be obtained.
It should be noted that, in addition to determining the position of the model component by obtaining the absolute coordinates of the positioning point or the end point of the positioning line of the model component, the absolute position of the model component may also be determined by using the coordinates of other points, as long as it is ensured that the selected point can reflect the absolute position of the model component in the building information model, the embodiment of the present application does not limit the type and specific position of the positioning point or the positioning line, and any manner that can realize the positioning of the model component in the building information model is suitable for the technical solution of the present application.
In some embodiments, determining the distance error of each model component with respect to the base point based on the positions of the anchor points or the anchor line end points and the positions of the base points comprises: calculating the distance between the model component and the base point based on the absolute coordinates of the positioning points or the positioning line end points of the model component in the building information model, and taking the numerical value of the decimal place as the distance error of the model component relative to the base point when the numerical value corresponding to the distance comprises the decimal place; and when the numerical value corresponding to the distance is an integer value, judging that the model component has no distance error relative to the base point.
Specifically, after obtaining the absolute coordinates of the positioning point or the positioning line end point of each model component in the building information model, the distance between the model component and the base point is determined by using the coordinates of the positioning point or the positioning line end point of the model component and the coordinates of the base point, where the distance is the distance between the model component and the base point in the base point coordinate system. The distance error elimination operation is required for model members corresponding to distances including fractional numbers, and the distance error elimination operation is not required for model members having distances of integer values.
In some embodiments, determining the corresponding offset of the model component when the offset is greater than the tolerance value using a predetermined offset algorithm comprises: and rounding the distance error corresponding to the model component when the distance error is larger than the tolerance value, enabling the distance between the rounded model component and the base point to be an integer, and taking the difference between the front distance and the rear distance as the offset of the model component according to the distance between the front model component and the rear model component which are rounded and the base point.
Specifically, before correcting the absolute coordinates of the model component with the distance error, the Revit API and the NET encapsulation method are used to calculate the offset value (i.e. offset) required by the model component, and the present embodiment encapsulates the rounding method into the NET method, and uses the NET method to calculate the offset of the model component. The following describes in detail the offset calculation process using the NET encapsulation rounding algorithm with reference to a specific embodiment, which may specifically include the following steps:
based on the numerical value behind the decimal point in the numerical values of the distances between the model component and the base point, taking the numerical value as a distance error, and changing the distance error into 0 or 1 in a rounding way; for example, when the distance between the model member a and the base point is 10.3cm, and the numerical value of the distance is rounded to obtain that the distance between the model member a and the base point is 10cm, that is, after the distance error of the model member a is eliminated, the distance between the model member a and the base point in the Revit model should be 10cm, the difference between the distances before and after rounding may be used as the offset amount of the model member in the Revit model, and in the above embodiment, the offset amount of the model member a is 0.3cm.
In some embodiments, adjusting coordinates of the locating point or locating line end point of the model member when the offset is greater than the tolerance value comprises: and correcting the absolute position of the model component in the building information model when the model component is larger than the tolerance value according to the offset corresponding to the model component when the model component is larger than the tolerance value, so that the absolute position of the model component relative to the base point after correction is an integer.
Specifically, the method and the device can adjust the coordinates of the positioning points or the end points of the positioning lines of the model component only when the positioning points or the end points of the positioning lines are larger than the tolerance value, that is, only when the distance error of the model component relative to the base point is larger than a certain threshold value (namely, the tolerance value), the distance error of the model component is eliminated, and the model component corresponding to the distance error smaller than the tolerance value is not eliminated, so that the efficiency of eliminating the errors can be improved, and certain precision requirements can be ensured.
Further, after the offset amount corresponding to the model member is calculated according to a rounding algorithm, the absolute position of the model member having a distance error larger than the tolerance value is corrected according to the offset amount, and the absolute position in the embodiment of the present application refers to the coordinates of the model member in a coordinate system having the base point as the origin, and thus may also be referred to as absolute coordinates. For example, continuing the example of the foregoing embodiment, if the offset of the model component a is calculated to be 0.3cm through a rounding algorithm, the coordinate corresponding to the positioning point or point end point of the model component a may be offset by 0.3cm, the offset direction may be determined by the direction of the connecting line between the positioning point or point end point and the base point, that is, the coordinate may be moved by 0.3cm along the connecting line between the positioning point or point end point and the base point toward the base point, so that the distance between the positioning point or point end point and the base point of the model component a after the offset becomes an integer distance of 10cm.
According to the technical scheme provided by the embodiment of the application, because the distance error generated by the model component in Revit during modeling is difficult to find, the application finds the absolute coordinates of the positioning points or the positioning line end points of different types of components through Revit API, and then shifts the positions of the positioning points and the positioning line end points by combining the preset tolerance value and the rounding algorithm, thereby finally achieving the purpose of eliminating the position error of the component. The position error of the model component can be corrected based on the base point position in the Revit model, the problem that scattered small numerical errors are generated when the model component is marked is fundamentally eliminated, and the model precision is improved so as to facilitate later application. The method and the device eliminate the absolute position error between the model component and the model base point, and also eliminate the relative position error between the model components. Compared with a mode of manually searching and moving the position, the distance error elimination method of the model component greatly improves the efficiency of eliminating the model component errors, reduces labor cost and time cost, and finally reduces the modeling cost of the building information model.
