From the above table, it is possible to determine the component depth level of each component of the above target building, which represents the amount of information required for modeling of the component element, according to professional accuracy requirements, i.e. the examples listed in the table.
In a possible embodiment, the precision requirement may be an application phase precision requirement, where the application phase precision requirement includes precision requirements of a design phase, a construction phase, and an operation and maintenance phase, for example, a target user may set the precision requirement of the operation and maintenance phase as: the depth level of the civil structure is required to be LOD100 and only models of layer 2 to layer 5 mechatronic devices and pipes are shown. And is not particularly limited herein.

And 203, processing the engineering drawing according to the depth grade to generate a building information model according with the depth grade.
Wherein, the depth level may represent the depth levels of all the partial components, and an identification policy may be determined according to the depth level, the first feedback data and the second feedback data, that is, a first level of detail identification is performed on the first target component and the second target component with the depth level of LOD 100; performing a second level of detail identification on the first target component and the second target component having the depth level LOD 200; performing a third level of detail identification on the first target component and the second target component having the depth level LOD 300; performing a fourth level of detail identification on the first target component and the second target component having the depth level LOD 400; and performing fifth level of detail identification on the first target component and the second target component with the depth level of LOD500, wherein the identification precision from the first level of detail identification to the fifth level of detail identification is increased in sequence.
The specific identification method may be an image identification technology, or may also be a search according to a component identifier, where different component structures have different component identifiers, and the component structure may be at least one of the following: rectangular columns, circular columns, i-beams, structural walls, building walls, electromechanical devices, pipes, panels, and the like, without limitation. In the embodiment of the present application, each component in the engineering drawing may correspond to a component identifier, and the component identifier may be at least one of the following: reference numbers, names, location labels, etc., without limitation. Specifically, a component identification set in an engineering drawing can be obtained; and then, identifying and analyzing the target engineering drawing according to the component identification set to obtain component data required by building an information model.

The fourth level of detail identification and the fifth level of detail identification are not described in detail herein.
Therefore, the identification strategy can be determined, different identification modes are adopted in different areas, and the identification efficiency of the engineering drawing is improved.
Further, the identification range may be determined based on third feedback data of the target user, the third feedback data representing a range of the building information model. If the target user can select a modeling floor or a modeling range, the modeling range can be selected in a mode of selecting partitions through frames or only selecting an outer vertical surface range (selected in a mode of screening pull-down conditions), the background algorithm identifies a corresponding range image layer in a drawing through the corresponding pull-down conditions, an original image is copied, and other unnecessary image layers are deleted.
And finally, identifying the engineering drawing according to the identification strategy and the identification range so as to generate the building information model according with the depth grade.
