Abstract
The present application provides a method and an apparatus for parsing and processing a three-dimensional CAD model, where the method includes: determining three kinds of adjacency relation information for each component in the three-dimensional model; performing aggregation processing on all components of the three-dimensional model, and generating three part hypothesis sets for the three-dimensional model; performing voxelization expression processing on each part hypothesis in each part hypothesis set, and generating voxelization information for each part hypothesis; inputting voxelization information of all part hypotheses in each part hypothesis set into an identification model to obtain a confidence score and a semantic category probability distribution for each part hypothesis; and constructing, according to the confidence score and the semantic category probability distribution of each part hypothesis in the part hypothesis sets, a high-order conditional random field model, and obtaining a semantic category analysis result for each component in the three-dimensional model.
