为了更好地对车间环境进行把控,同时针对车间目标像素级分割任务样本少、类别多、尺度变化大导致的语义分割精度低的问题,设计了一种改进的U-Net车间场景分割模型.改进的模型采用Rep-VGG轻量级主干网络,并在U-Net上采样阶段引入金字塔拆分注意力机制,以增加模型的特征表达能力及推理速度.模型训练则采用Dice-Cross Entropy组合损失函数以解决样本不均衡导致的难以训练的问题.实验数据表明该模型在自建的小样本车间数据集上可达到快速、轻量化及高精度的分割效果.
Workshop Scene Segmentation Method Basedon Improved U-Net
In order to better analyze the workshop environment and solve the problems of low semantic segmentation accuracy caused by few sample samples,many categories and large scale changes of the target pixel-level segmentation task of the workshop,an improved U-Net workshop scene segmentation model was designed.The improved model used Rep-VGG lightweight backbone network,and introduced the pyramid splitting attention mechanism in the sampling stage of U-net to increase the feature representation ability and reasoning speed of the model.In model training,Dice-Cross Entropy combination loss function was adopted to solve the problem of difficult training caused by unbalanced samples.Experimental data showed that the model could achieve fast,lightweight and high-precision segmentation on the self-built small-sample workshop dataset.
