Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein.
It should be noted in advance that, in the specific embodiment of the present invention, the communication connection and the information interaction are performed through the service terminal and the user terminal, and the automatic information acquisition and judgment of the service terminal are implemented, specifically, the user terminal may be a projection device, specifically, refer to an AR projection technology and an image technology, and the service terminal is a server or a computer.
Example 1
As shown in fig. 1, the present invention is a flow chart of a BIM-based component quality anomaly detection method, which is executed by a server terminal and a mobile terminal together. As shown in fig. 1, the method mainly includes the following steps:
s1, constructing a BIM model of the whole construction building by combining construction drawings;
it is understood that there is a special department to design and present the drawing of the building before the construction, which is used as the basis of the construction and contains all the detected parameters and data, so that the parameters and data in the drawing are input into the server to construct the three-dimensional figure of the construction building, namely, the BIM model in the present embodiment.
S2, obtaining virtual reference component information of the component to be detected according to the BIM, and sending the virtual reference component information to the mobile terminal;
in an optional manner, in step S2, the step of obtaining basic parameter information of the member to be detected includes:
s21, decomposing the component to be detected from the BIM model, and acquiring the connection relation between the component to be detected and relevant parts in the BIM model;
because the information such as the size of the building in the BIM model is constructed according to the drawing, the information can be understood as the installation information, the size information and the like of the standard component, and the installation relation and the connection relation of the component, such as the distance relation between the component and the adjacent component and the like, can be performed and obtained by the same staff so as to detect and judge the quality of the component to be detected from multiple aspects.
S22, acquiring the decomposed relevant dimension information and installation parameter information of the component to be detected;
and S23, generating virtual reference member information of the member to be detected in the actual building according to the acquired related dimension information and the acquired installation parameter information.
S3, the mobile terminal receives the virtual reference member information and generates a virtual reference member;
in the step S3, the virtual reference component refers to projection information in a construction building when the component to be detected meets the installation standard;
and the projection information comprises at least one of holographic projection information of the component to be detected, plane projection information of each surface of the component to be detected, angle projection information of side lines of the component to be detected and proportion projection information of adjacent side lines of the component to be detected, and it is easy to understand that if the standard size information of each plane of the component to be detected is provided, the standard size information is compared with the surface matched with the component to be detected in practice, and a judgment result of the component quality can be obtained easily.
Preferably, the projection information includes standard projection information of the component to be detected and error range information meeting the building construction requirements, it is to be explained that the error allowable range is marked at the outer side or the inner side of the side line of the standard projection, that is, when the projection is used for comparing with the actual component to be detected, the error allowable range during construction of the component to be detected can be obtained quickly, so that the function of auxiliary judgment is achieved, and the subsequent independent determination and detection of the error are not needed.
In an optional mode, the standard projection information and the error range information are preferably distinguished and projected by different colors, so that the standard projection information and the error range information can be better distinguished, and the judgment of field workers by naked eyes is facilitated.
And S4, comparing the difference between the virtual reference member and the member to be detected in the actual construction building, and judging whether the quality of the member to be detected is abnormal.

s41, adjusting the position of the virtual reference component generated by the mobile terminal to be in the standard position of the construction building;
it should be understood that, in this step, when the projection device is installed, an installation distance needs to be calculated, where the distance refers to a distance from the component to be detected, because it is understood that, when projection is performed, the projected distance has a certain relationship with the size of the image, it is to be ensured that the virtual reference component is projected to a correct position, in this embodiment, the correct position may be understood as creating a spatial coordinate system with an area of an actual construction building or dividing longitude and latitude in the space by using a device such as a theodolite, and a longitude and latitude position or a spatial position of each component relative to a longitude and latitude in the actual building space can be known through the BIM model, that is, the correct position refers to the position.
S42, observing the size relation between the virtual reference component and the component to be detected;
if the dimensional relation meets the construction requirement, the quality of the component to be detected is normal;
and if the size relation does not meet the construction requirement, judging that the quality of the component to be detected is abnormal.
For convenience of understanding, it should be noted that if the quality of the component to be detected is detected after the component to be detected is installed, if the detected quality meets the requirement, each step before the component to be detected meets the requirement, and if the quality of the component to be detected is abnormal, the reason why the component may be abnormal in the process from production to installation is traced, which includes: reasons during transportation, reasons during manufacture of the components, reasons during storage and maintenance of the components, etc.
