A target detection algorithm for tree encroachment on transmission lines based on improved YOLOv11
An aerial image detection algorithm named MA-YOLOv11 is proposed based on YOLOv11. First,the SE-C3k2 module is designed to preserv the features of small branches while achieving lightweight. Second,the multi-scale shared convolution module replaces the SPPF module. Then,a novel HMA-Net network structure is constructed by incorporating the MAFPN architecture,adding a small target detection head P2,and reducing redundant paths. This enhances the interaction between shallow detail information and high-level semantic information,thereby improving the detection accuracy for small targets. Finally,a multi-scale attention detection head is employed to effectively handle scenes with leaf occlusion. Experimental results show that compared to the baseline model,the improved MA-YOLOv11 model increases of 4.2% in precision,4.1% in recall,and 5.2% in the mAP50 metric,validating the effectiveness of this method for treeencroachment detection.
