Title:
ENDOSCOPIC IMAGE PROCESSING SYSTEM AND ENDOSCOPIC IMAGE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/054419
Kind Code:
A1
Abstract:
This endoscopic image processing system imparts an acquired endoscopic image to a trained model, acquires position information and orientation information that indicate the position and orientation of an endoscope that captures the endoscopic image, and stores the acquired position information and orientation information in association with the endoscopic image, wherein the trained model has been machine-trained on the basis of a plurality of pieces of teacher data in which the correct answers of the position and orientation of the endoscope that has captured an endoscopic image for a teacher are associated with the endoscopic image for a teacher.
