Patent ID: 11262315

Abstract:
An attached substance determination method causes a computer to determine whether or not an attached substance is attached to an inspection target object, in which the computer includes at least one processor, and the at least one processor is configured to (a) acquire, as learning data, a spectroscopic image obtained by imaging a first type sample having the attached substance attached to a base with a spectroscopic camera and a spectroscopic image obtained by imaging a second type sample having no attached substance attached to the base with the spectroscopic camera, in which spectroscopic images of a plurality of kinds of the first type samples having different kinds of the bases and different kinds of the attached substances and spectroscopic images of a plurality of kinds of the second type samples having different kinds of the bases are acquired as the learning data, (b) generate, based on the learning data, a determination model with a spectroscopic image of the inspection target object as an input and a determination result relating to presence or absence of the attached substance as an output, (c) acquire the spectroscopic image of the inspection target object, and (d) input the spectroscopic image of the inspection target object to the determination model and determine the presence or absence of the attached substance based on the determination result output from the determination model.
