Embodiment Construction
[0070] A fast three-dimensional model part category automatic labeling method disclosed by the present invention specifically includes the following steps ( figure 1 is the flowchart of the whole method):
[0071] Step 1, rapid training of the 3D model annotation training set: the training set contains similar models and the parts in the model have been given standard annotations, where the annotation information includes the category annotation of each mesh patch in the 3D model belonging to the constituent parts and each Mesh edges are subject to category labeling of boundary edges. Such as Figure 2a As shown, it is the standard label of the patch. Figure 2b is the standard label for mesh edges. Each aircraft model mesh patch is marked by different label classes indicated by different colors, and the labels in the training set are standard labels. Through rapid training on the 3D model labeling training set, a fast patch labeling model and a boundary labeling model tha...
