WIPO Patent Application WO/2020/121739
Kind Code:
A1
Abstract:
The present invention pertains to an image-matching process for carrying out positioning of a pattern on design data and a pattern in an image, and in particular pertains to an image-matching process in which there is used a model constructed by machine learning. This method includes: converting a CAD pattern, which was designated in design data, to a CAD image (301); inputting the CAD image (301) to a model constructed by machine learning; executing calculation in accordance with an algorithm defined by the model to thereby output a similar image (321) from the model; and determining a pattern in the similar image (321) that has a shape closest to the shape of the CAD pattern (322), from among a plurality of patterns in an image generated by an image generation device (100).
