A learning method, a learning device, and a welding defect detection device provided with the learning device.

摘要

PROBLEM TO BE SOLVED: To provide a learning method and a learning device of a classifier used in a welding defect detecting device capable of detecting welding defects easily and accurately without requiring specialized knowledge, and a welding defect detecting device including the learning device. I will provide a. An image acquisition step of acquiring an inspection image obtained by irradiating a welded portion with radiation, and a welding defect pixel corresponding to a welding defect and a normal state other than the welding defect pixel with respect to the pixels included in the inspection image. Based on the display processing process that executes the process for presenting the work screen that can be labeled according to each pixel to the user, and the result of the labeling performed on the work screen according to the input operation by the user. , To detect welding defects using a learning data set that combines the inspection image and the labeling image with the labeling image generation process that generates the welding defect pixel and the labeling image that divides the normal pixel from the inspection image. The discriminator learning step of repeatedly executing the learning of the discriminator used is included. [Selection diagram] Fig. 1
