[0091] In actual application, when the digital twin engine performs digital simulation on the target building, there may be some simulation problems, such as unreasonable model content layout, etc. The embodiment of the present invention assists the user in reviewing the digital model. During the review of the digital model, the user can input the review opinions, determine the model optimization target based on the review opinions, and import it into the digital twin engine. The digital twin engine will optimize the displayed digital model according to the model optimization target; based on the review opinions, determine the model optimization target, for example: if the review opinion is that the equipment model parameters in a certain model area are not comprehensive, then the model optimization target is to fully update the equipment model parameters in the model area.

[0093] Acquire multimodal data of the user; the multimodal data includes: proficiency in reviewing content types, management responsibilities, etc.;

[0094] Determining content constraints based on the multimodal data; the content constraints are to constrain the target content to be suitable for the user to view, such as the type of content that the user is good at viewing;

[0101] The standard set conditions include:

[0102] The straight-line distance between the content areas of each of the target contents in the target content set is less than or equal to a preset distance threshold; the distance threshold may be, for example, 20 meters; setting this standard set condition can ensure that the contents in the visualization sphere are closer together;

[0103] and / or,

[0104] The similarity between the first characterization vector in the target content set and the preset standard characterization vector corresponding to the user is greater than or equal to a preset similarity threshold. The similarity threshold can be, for example, 85%; the standard characterization vector is constructed in the form of a feature vector from the target content set (for example, three voltage device models) representing the upper limit of the content that the user can view at a single time; setting this standard set condition can ensure that the content within a visualization sphere can be viewed by the user at a single time.

[0105] Generally, when users inspect digital models, they need to perform operations and inspections themselves, which is very cumbersome and the inspection convenience is low.
