摘要
在工地堆放木材物料时,室外环境容易导致木材表面出现受潮变形、干裂等异常状况。针对现有检测算法在木材物料表面异常检测方面精度欠佳、模型计算复杂度高等问题,提出一种以YOLOv8n为基础模型的轻量级小目标检测算法(YOLO-ESN)。该算法引入空间-通道重构卷积(SCConv)模块以及针对小目标检测的归一化Wasserstein距离(NWD)损失函数,同时将基于跨空间学习的高效多尺度注意力模块(EMA)嵌入主干网络,以此减轻遮挡及背景干扰带来的影响。改进后的算法在木材缺陷数据集上进行了实验验证,相较于原算法,其mAP@0.5提升了3.6%,参数量降低了23.3%,实现了对堆放木材物料异常情况的实时准确检测。
