1. An information processing device, comprising:
circuitry configured to:
acquire a polarized captured image of an abnormality detection target based on an imaging operation;
set a plurality of parameters that is used to generate a polarized rendered image of the abnormality detection target,
wherein the plurality of parameters includes a light source parameter related to a light source, a geometry parameter related to the abnormality detection target, a material parameter related to a polarization characteristic of the abnormality detection target, and a camera parameter associated with the acquisition of the polarized captured image;
generate the polarized rendered image of the abnormality detection target based on the plurality of parameters; and
detect an abnormal region of the abnormality detection target based on a difference between the acquired polarized captured image and the generated polarized rendered image.
