AI Technical Summary
Existing weld seam recognition technologies are difficult to deploy efficiently on resource-constrained edge devices. Furthermore, traditional methods are sensitive to imaging noise, resulting in decreased recognition accuracy and insufficient generalization ability, making them difficult to adapt to various types of weld seams and complex working conditions.
Based on the YOLOv11-pose network architecture, the backbone network is replaced with the Starnet structure, and the FreqFusion feature fusion module is introduced into the neck network. Combined with the key point prediction branch and depthwise separable convolution, multi-task synchronous prediction is achieved.
While reducing computational complexity and the number of parameters, it improves the accuracy and efficiency of weld seam identification and positioning, making it suitable for deployment on edge devices with limited computing resources.
