Claim 12:
13. An apparatus for determining a three-dimensional atomic level structure, comprising:
an atomic model generator that generates one or more three-dimensional atomic models corresponding to a nanomaterial to be measured;
a three-dimensional learning data generator that generates three-dimensional atomic structure tomogram volume data corresponding to the nanomaterial to be measured as three-dimensional learning data by simulating and reconstructing three-dimensional tomography based on the one or more three-dimensional atomic model;
a deep learning filter generator/learner that generates a deep learning filter by training a machine learning model using the three-dimensional learning data; and
a three-dimensional atomic level structure determiner that generates second three-dimensional atomic structure tomogram volume data, in which an atomic arrangement region with insufficient data is corrected, by filtering first three-dimensional atomic structure tomogram volume data acquired through electron microscopy measurement of the nanomaterial to be measured with the deep learning filter, and determines a three-dimensional atomic level nanostructure of the nanomaterial to be measured based on the second three-dimensional atomic structure tomogram volume data.
