Abstract：Aimingatthebotteneck problemof insufficientadaptabilityof traditionaldefectdetection methodsinautomated wood processng industry，research onintellgentdetectiontechnologybasedondeep learning iscarriedout，and adatasetcovering multi-species woodcharacteristicsand typicaldefecttypes is proposed.Applyingobjectdetectiontechnology to defect detection，using dilation wise residual（DWR）module to optimize C2f module，and proposing task aligned dynamic detection head （TADDH）and feature focusing spread pyramid network （FSPN） to impove YOLOv8 algorithm（DFT-YOLO）.The experimental results showed that a significant improvement in accuracy，reaching 96.8%， which was 7.9 higher than the original model.On the averageaccuracyof the keyevaluation indicators mAP50 and mAP50-95，the impoved model reached 93. 8% and 75.2% ，respectively，increasing by 6.8% and 17.5% ，respectively.While improving the detection accuracy，the number of parameters of the model had decreased by approximately 1/6 （ 16.2% ）.The impoved model can provide a lightweight detection method for wood defects.
