Drug identification device, drug identification method and program, drug identification system, drug loading table, illumination device, imaging assistance device, trained model, and learning device

A drug identification method, comprising:

• an image acquisition step of acquiring a captured image generated by imaging at least one drug to be identified that is imparted with engraved mark and/or print;
• a drug detection step of detecting a region of the drug to be identified from the captured image;
• an engraved mark and print extraction step of processing at least the region of the drug to be identified in the captured image to acquire an engraved mark and print extraction image that is an image of the engraved mark and/or print of the drug to be identified extracted from the region of the drug to be identified;
• and
• a first drug type recognition step of receiving input of the engraved mark and print extraction image, and inferring a drug type of the drug to be identified to acquire at least one candidate of the drug type of the drug to be identified.

A learning device, comprising:

• a training data collection unit configured to collect a retraining data set including an engraved mark and print extraction image that is an extracted image of engraved mark and/or print of a drug to be identified, and information on a correct drug type of the drug to be identified, as a set;
• and
• a relearning unit configured to perform relearning of a second trained model by using the collected retraining data set, wherein
• the second trained model receives input of a second image that is an extracted image of the engraved mark and/or print of the drug and outputs a drug type of a drug corresponding to the engraved mark and/or print.

A drug identification device, comprising:

• an image acquisition unit configured to acquire a captured image generated by imaging at least one drug to be identified that is imparted with engraved mark and/or print;
• a drug detection unit configured to detect a region of the drug to be identified from the captured image;
• an engraved mark and print extraction unit configured to process at least the region of the drug to be identified in the captured image to acquire an engraved mark and print extraction image that is an image of the engraved mark and/or print of the drug to be identified extracted from the region of the drug to be identified;
• and
• a display control unit configured to display, on a display, at least one of:
• an image of at least the region of the drug to be identified in the captured image;
• the engraved mark and print extraction image;
• and an image of the drug to be identified with the engraved mark and/or print being emphasized, in a state where a direction of the engraved mark and/or print is made upright.
