Japanese Patent JP2023080509
Kind Code:
A
Abstract:
To provide an annotation apparatus and a method that enables a simple and highly accurate annotation.SOLUTION: An annotation apparatus is configured using a calculator and annotates 3D shape data. The annotation apparatus includes an input unit that inputs a 3D CAD model, a text, and definition information of a label, an arithmetic unit that generates an annotation data set through annotation processing, a storage unit that stores the generated annotation data set, and an output unit that outputs a processing result of the arithmetic unit. The arithmetic unit includes an annotation unit that acquires annotation information including a partial shape of the 3D CAD model and a label according to a unique expression in the text or label definition information, and a metadata generation unit that generates metadata that associates the annotation information with the 3D CAD model and a partial shape of heterogeneous format data derived from the 3D CAD model. The annotation data set including the generated metadata, the 3D CAD model to which the metadata refers, and the text are stored in the storage unit.SELECTED DRAWING: Figure 1
