概述

本项目研究基于YOLOV13的改进算法yolo13-C3k2-WDBB，应用于实验室石棉纤维形态识别目标检测任务。算法针对石棉检测特点进行了优化，采用C3k2和WDBB模块增强特征提取能力。系统使用QT作为前端技术栈，实现用户友好的交互界面。数据集包含4类石棉纤维标记：thick-dark-mark、thick-light-mark、thin-dark-mark和thin-light-mark，覆盖不同厚度和明暗特征的石棉纤维样本。该研究旨在提高石棉检测的准确性和效率，为实验室石棉分析提供自动化解决方案。

任务目标

石棉作为一种有害的矿物纤维材料，其准确检测对环境保护和人类健康具有重要意义。传统石棉检测方法依赖人工识别，存在效率低下、主观性强等问题。本研究旨在开发一种基于改进YOLOv13架构的石棉纤维检测算法，通过引入C3k2和WDBB模块增强特征提取能力，实现对四种不同形态石棉纤维（thick-dark-mark, thick-light-mark, thin-dark-mark, thin-light-mark）的精确识别。该研究不仅将提高石棉检测的自动化水平和准确率，还将为环境监测和职业健康防护提供技术支持，具有重要的理论价值和实际应用意义。

数据集信息

该数据集包含四种石棉纤维类别：thick-dark-mark（厚深色标记）、thick-light-mark（厚浅色标记）、thin-dark-mark（薄深色标记）和thin-light-mark（薄浅色标记）。这些类别涵盖了石棉纤维在不同厚度和颜色特征下的形态变化，全面反映了实际环境中石棉纤维的多样性。选择此数据集的优势在于其能够有效模拟真实场景中石棉纤维的复杂形态，为算法提供具有挑战性的训练样本。此外，该数据集的分类标准明确，便于算法对不同特征石棉纤维的精确识别，有助于验证改进YOLOv13架构结合C3k2和WDBB模块在特征提取方面的优越性，从而提升石棉检测的自动化水平和准确率。
