Abstract：When the timber materialsare stackedontheconstruction site，theoutdoorenvironment is prone to abnormal problemssuchas moisture deformationand drycrackingonthe surfaceofthe timber.Aimingatthe problems ofpooraccuracy andhighcomputationalcomplexityoftheexisting detectionalgorithmsonthesurfaceof timber materials，alightweightsmall target detection algorithm（YOLO-ESN）basedonYOLOv8nis proposed.Thealgorithm introduces the SpatialandChannel ReconstructionConvolution （SCConv） module and the Normalized WassrsteinDistance （NWD）lossfunction forsmal target detection.Atthesametime，itembeds theEffcientMulti-ScaleAtention（EMA）modulebasedonCross-SpatialLeaminginto thebackbone network toreduce the impact ofoccusionandbackgroundinterference.Theimprovedalgorithmis experimentally verified on the timber defect dataset. Compared with the original algorithm，its is increased by 3 . 6 % ，and the parameter quantity is reduced by 23 . 3 % ，which realizes the real-time and accurate detection of the abnormal situation of stacked timbermaterials.
