Information processing apparatus, learning device, information processing system, information processing method, and non-transitory storage medium

An information processing apparatus comprising:

• an input configured to input sample manufacture information of a sample;
• and
• a hardware processor configured to
• predict orientation information of the sample after having undergone learning, as a learning unit, by associating sample manufacture information of samples with a set of orientation information obtained based on Talbot images, and
• calculate, as a calculator, the predicted orientation information of the sample.

An information processing apparatus comprising:

• a hardware processor configured to
• obtain orientation information based on a Talbot image of a sample, and
• perform, as a structure analyzer, structural analysis of the sample based on the orientation information;
• and
• an output configured to output a result of the structural analysis.

A non-transitory computer readable storage medium storing instructions that, when executed, cause at least one hardware processor to perform an operation as a learning device, wherein

• the learning device comprises a first learning unit, a second learning unit, or both the first learning unit and the second learning unit,
• the first learning unit is configured to:
• obtain sample manufacture information of a sample;
• obtain a Talbot image obtained by imaging the sample with an X-ray Talbot imaging apparatus;
• and
• learn by associating the sample manufacture information of the sample with the Talbot image, and
• the second learning unit is configured to:
• obtain the sample manufacture information of the sample;
• obtain the Talbot image obtained by imaging the sample with the X-ray Talbot imaging apparatus;
• obtain orientation information based on the Talbot image;
• and
• learn by associating the sample manufacture information of the sample with the orientation information.

An information processing method of an information processing apparatus, the information processing method comprising:

• calculating orientation information based on a Talbot image of a sample;
• performing structural analysis of the sample based on the calculated orientation information;
• and
• outputting a result of the structural analysis.
