Abstract: Aiming at the challenges of missed detection,false detection and arbitrary distribution of defect angles in smalltargetdefectdetectioninwelding extemaldefectimagedetection,anoptimizedand improvedmodelbasedonYOLOv8, YOLO-weld,isproposed.FirstlySPF-weldandC2f_DBB_CBAMmodulesaredesigned tonhancethecontextinfoation agregationabilityandmulti-scale featurefusioneffectofYOLO-weldmodel.Secondly,theOBBdetectionheadisintroduced toaccuratelycapturedirectionaldefects,soastoimprovethedetectionacuracy.Finalytheexperimentalresultshowthat compared with the YOLOv8 model, the YOLO-weld model improves the accuracy,recall,harmonic mean (F1) and mAP @0.5 by 3.2% 0 2.6% 0 4.0% and 3.9% ,respectively,which fully proves the effectiveness of the YOLO-weld model improvement.
