Fan blade surface defect detection method, device and system, and storage medium

Abstract

The application discloses a fan blade surface defect detection method and device, system and storage medium, and comprises the following steps: selecting and dividing a fan blade surface defect dataset to obtain a training set, a verification set and a test set; an improved YOLO11n target detection network is constructed, and the improvement comprises structural optimization of a backbone network and a neck network of the target detection network; an initial target detection model after structural optimization is trained through the training set and the verification set, and the trained target detection model is verified in performance through the test set, and the target detection model is obtained after verification; and the target detection model is used for fan blade surface defect detection.
