Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, for the purpose of making the objects, technical solutions and advantages of the present invention more apparent.
Example 1
Referring to fig. 1, embodiment 1 of the present invention provides a method for positioning a test lot based on a BIM model, including the steps of:
step 1, acquiring acceptance information such as a problem image with quality safety problems in a construction site, and the longitude and latitude coordinates corresponding to the problem image. The BIM model can be displayed on handheld equipment such as a mobile phone after being quantized, so that a problem image can be acquired through the handheld equipment in the acceptance process. The longitude and latitude coordinates corresponding to the problem image can also be obtained by the handheld device of the acceptance person, for example, the longitude and latitude coordinates of the acceptance person are obtained by mobile phone positioning, and are equivalent to the longitude and latitude coordinates of the problem image. In a more preferred embodiment, the problem image or the problems, acceptance time, acceptance person name or number, component description, etc. of each component in the problem image may be uploaded together with the problem image when the problem image is acquired. Further, for a target member in some problem images, it is necessary to acquire altitude coordinates, such as altitude coordinates, in addition to longitude and latitude coordinates, to further determine the position of the target member. Specifically, the longitude and latitude coordinates can be obtained in various manners, such as a GPS system, a Beidou system, a GLONASS and the like.
And 2, converting longitude and latitude coordinates corresponding to the problem image into modeling reference coordinates under the BIM model. Specifically, in the BIM model, a latitude and longitude coordinate may be preset as the origin of coordinates, and then projected onto the three-dimensional coordinates of the BIM model through a coordinate conversion formula. Specifically, the present invention is premised on that each construction element has its own unique three-dimensional coordinates in the BIM model, and it is preferable that the three-dimensional coordinates be defined by the geometric center of the construction element or a point on the geometric center.
And 3, determining a target component corresponding to the problem image according to the modeling reference coordinate and the coordinate range of the component in the BIM model.
And then executing step 4, obtaining the association relation between the target component and the test batch, and establishing the association relation between the problem image and the test batch according to the association relation between the target component and the test batch.
Specifically, the modeling reference coordinate and the target precision corresponding to the problem image may be obtained first, then the target positioning range may be determined with the modeling reference coordinate as the center and the target precision as the radius area, and the verification batch information may be searched within the target positioning range, and the searching process may specifically query the component information summary table of the BIM model, so as to generate the entity information of at least one target component and the corresponding verification batch information within the target positioning range. So that the entire test lot information in the area is displayed to the acceptance person, and the acceptance person confirms or selects the information. And finally, associating the confirmed or selected inspection batch information, the problem image, the problems of the target component, the acceptance time, the name or number of the acceptance person, the description of the target component and the like, and automatically uploading or generating an acceptance report or executing corresponding steps according to the acceptance requirement. The target precision can be a default value, such as the positioning precision of a mobile phone positioning system, or can be set by an acceptance person, such as in an open air environment, and can be set smaller, such as 5 meters; in a closed environment, the target precision can be set to be larger, such as 20 meters; if the check batch information cannot be found under the default precision, the positioning precision can be manually enlarged until the check batch information or the correct check batch information appears.
In step 1 of the preferred embodiment, corresponding standard segment information, engineering information, supervision unit information, construction unit information and the like can be generated and displayed according to longitude and latitude coordinates corresponding to the problem image, and the displayed information is set according to requirements, so that an acceptance person can rapidly correspond a target component to an inspection batch or/and can conveniently express an acceptance result.
The method specifically comprises the following steps of:
S301, obtaining modeling reference coordinates and target precision corresponding to the problem image;
s302, determining a target positioning range by taking the modeling reference coordinate as a center and taking the target precision as a radius;
S303, inquiring a component information summary table of the BIM model, and generating entity information and corresponding check batch information of at least one target component in the target positioning range.
Wherein, referring to fig. 2, the method for obtaining the target precision specifically comprises the following steps:
S3011, acquiring a preset precision range;
S3012, collecting current environment information, identifying the current environment information, and judging the signal intensity of the current environment information according to the identification result;
s3013, selecting an initial precision value in the preset precision range according to the signal intensity;
S3014, generating the quantity of the inspection batches of the target component entity corresponding to the modeling reference coordinate under the initial precision value through the BIM model, reducing the initial precision value by a first preset amplitude when the quantity of the inspection batches is larger than a first preset value, repeating the steps until the quantity of the inspection batches is smaller than or equal to the first preset value, taking the corresponding current precision as the target precision, and taking the target precision as the default precision under the current environment.
The process can quickly and intelligently confirm the target precision, avoid the influence of the positioning precision change on the method, and further ensure that the information of the inspection batch can be accurately and quickly found.
In another preferred embodiment, when the number of verification batches of the target component entity corresponding to the modeling reference coordinate under the initial precision value is generated through the BIM model, when the number of verification batches is 0, the initial precision value is increased by a second preset amplitude, and the steps are repeated until the generated number of verification batches is not 0, and the number of verification batches is smaller than or equal to the first preset value, the corresponding current precision is used as the target precision, and the target precision is used as the default precision under the current environment. The process can be automatically realized, and the selection can be performed manually by an acceptance person. If the first preset value is 5m, if the check batch information cannot be found within the precision range, the check batch information is continuously searched under the precision of 10m, and if the check batch information cannot be checked yet, the check batch information can be continuously searched under the precision of 15m until the check batch information is found or the maximum preset precision is exceeded.
In the above embodiment, the number of verification batches of the target component entity corresponding to the modeling reference coordinate under the initial precision value is generated through the BIM model, and when the number of verification batches is 0, all the current verification batch information is displayed through the BIM model. If the number of the found inspection lots is small, the inspection lots can be displayed in a simple list mode; if the number of the found inspection lots is large, the inspection lots can be displayed in a multi-level submenu mode, so that an acceptance person can find and print the correct inspection lots quickly.
Specifically, the preset precision range is 5-20 meters, the initial precision value is smaller as the signal corresponding to the current environment information is stronger, and the initial precision value is larger as the signal corresponding to the current environment information is weaker, so that the problem image can be conveniently, accurately and rapidly associated with the inspection batch.
The method can be directly implemented on a mobile phone (corresponding app is installed on the mobile phone) or on a special handheld terminal.
The method is described below by way of a specific implementation scenario: inspection personnel carry out inspection to the second floor of the airport terminal building, the constructional column is found to be not in accordance with the inspection standard, the inspection personnel opens a corresponding app or browser on a mobile phone, the app or browser is accessed to carry out positioning, the handheld terminal can display zero, one or more pieces of inspection batch information generated by positioning coordinates, if zero, the inspection personnel can select to expand the searching range, if the positioning precision is improved to 15m from 5m until the inspection batch information appears, and the inspection personnel can manually select from all the displayed inspection batch information at the moment. If one or more check persons click to confirm or select, after confirming the check batch information, the handheld terminal displays the check batch information, such as corresponding check standards, construction units, parameter values, design indexes, mark numbers and the like, if problems are found, pictures, descriptions (which can be self-described or can be correspondingly described according to the check standards) and the like of the constructional column are uploaded, and the system can generate corresponding check reports or does not process the check reports and then send the check reports to a total package unit, a supervision unit or/and a corresponding sub-package unit and the like.
