And step S13, acquiring the initial component corresponding to the image element, and adjusting the initial component according to the label information of the image element to obtain the building component.
The BIM model generation equipment acquires an initial component corresponding to the image element, and adjusts the initial component according to the labeling information of the image element to obtain a building component; specifically, the method comprises the following steps:

And c3, if the sum of the first dimension is equal to the second dimension and the sum of the second dimension is equal to the third dimension, judging whether the elevation of the structure construction drawing is the same as the elevation of the building construction drawing.
If the sum of the first dimension is equal to the second dimension and the sum of the second dimension is equal to the third dimension, the BIM model generation equipment judges whether the elevation of the structure construction drawing is the same as the elevation of the building construction drawing; the elevation of the structure construction drawing is different from the elevation of the building construction drawing, and the structure construction drawing and/or the building construction drawing cannot be checked.
Step c4, if the elevation of the structure construction drawing is the same as the elevation of the building construction drawing, executing the following steps: and analyzing the structure construction drawing to obtain image elements in the structure construction drawing and the labeling information of each image element.

In this embodiment, after the BIM model generating device obtains the structure construction drawing and the building construction drawing, the structure construction drawing and the building construction drawing are analyzed to determine whether the structure construction drawing and the building construction drawing have errors, and when the structure construction drawing and the building construction drawing do not have errors, the structure construction drawing and the building construction drawing are further analyzed to generate the BIM model.
Further, on the basis of the above embodiments of the present invention, a third embodiment of the BIM model generation method of the present invention is provided.
This embodiment is a step after step S14 in the first embodiment, and is different from the above-described embodiments in that:
and d1, determining the starting position and the target position of the updating operation when the updating operation triggered based on the BIM model is received.
