摘要

摘要

En 中文
随着环保意识的普及,环保领域对家电工厂塑料废弃物的回收利用日益关注。在此背景下,光谱技术,特别是光谱数据与基于深度学习的分类技术的结合,已逐渐成为解决塑料分类挑战的关键方案。然而,关于塑料分类模型的轻量化部署研究尚显不足,这成为未来研究的重要方向之一。本文提出了一种创新的特征提取方法,该方法在保留整体光谱特征的同时,局部消除噪声引起的精细特征。这一改进显著提升了算法的准确性,使精度提高了2%。为扩充数据集样本量,我们设计了一种塑料光谱生成模型(PSGM)用于生成合成数据。通过利用生成的光谱数据扩充数据集,最终算法的准确率进一步提升了3%。此外,本文还提出了一种轻量级塑料分类模型(LPCM),该模型仅占用0.77M空间,同时保持98%的准确率和0.003秒的检测速度。该模型不仅满足了工厂废旧电器回收的实用需求,还有望应用于嵌入式控制器,展现出广阔的应用前景。
