For example, the spatial relationship of a member such as a "door" needs to be determined currently, so that the layer corresponding to the member such as the "door" can be screened out through the screening operation. The target information is the layer corresponding to the member "door".
S103, determining a target picture according to the target information;

S104, extracting a target object from the target picture according to a target identification algorithm to obtain object information of the target object;
the image may be placed in a recognition model corresponding to a determined component type trained in advance to detect, so as to determine a target object and object information of the target object, that is, a component included in the determined component type is the target object, for example, the target object is a "door", and the object information may be pixel coordinate data of the target object, and the like.
S105, analyzing and processing the object information to obtain primitive information;

The primitive information is information that can accurately lock the position of the primitive in the drawing, and may be, for example, geometric coordinate information or vector information.

S106, determining a plurality of target objects from the drawing information according to the primitive information;
the drawing to be analyzed may include a plurality of target objects whose spatial position relationships need to be determined, for example, a plurality of members whose member types are "gates" included in one CAD drawing, and the primitive information corresponding to each target object is the same, so that a plurality of target objects may be determined according to the primitive information.
