1.数据采集
通过企业自有摄像设备自行采集道路路面图像，同步记录图像ID、采集时间、设备型号、地理坐标、光照条件、天气状况、车道编号等数据。
2.数据预处理与标注
通过数据清洗剔除模糊、重复图像。按7:2:1比例划分训练集/验证集/测试集。设置多级标注体系：
​一级标签（物体类型）：轮胎/货物/建筑废料/其他
​二级标签（尺寸分级）：小型（最长边<30cm）/中型（30-100cm）/大型（>100cm）
​三级标签（危险等级）：低危（可延缓处置）/中危（需警示标识）/高危（立即清除）
​辅助标注：物体边界框坐标
3.模型选择与初始化
采用YOLOv9+PointNet++多模态融合模型，初始化参数并优化超参数：学习率0.001-0.0001动态调整，批量大小16，自定义锚框参数适配长条形货物等特殊形态。
4.模型训练
基于PyTorch实施分布式训练，采用混合精度训练（FP16）提升效率。设置训练时长，数据增强模拟复杂场景，添加动态模糊、逆光、车辆遮挡等特效，模拟夜间低光照及雨雾天气条件。设置早停机制（patience=15），梯度裁剪：max_norm=1.0。
5.模型评估
在训练模型的过程中，使用验证集调整超参数，训练完成后在测试集上评估模型表现，评估指标包含：
基础性：mAP@0.5、误报率
场景鲁棒性测试：夜间检出率

This dataset is primarily designed to enhance the recognition capability and accuracy of AI models for road debris. Training on this dataset enables AI models to accurately identify traffic-hazardous foreign objects such as tires, cargo fragments, and construction waste, and can be applied to intelligent analysis systems for road patrol vehicles and surveillance cameras on highways and urban roads. Additionally, this dataset can provide data support for road safety management systems, helping to achieve automatic linkage of debris positioning and clearance systems.

1. Data Collection
Road surface images are collected independently using the enterprise's own camera equipment, with synchronized recording of data including image ID, collection time, device model, geographic coordinates, lighting conditions, weather conditions, and lane number.

2. Data Preprocessing and Annotation
Blurred and duplicate images are removed via data cleaning. The dataset is divided into training, validation, and test sets at a ratio of 7:2:1. A multi-level annotation system is established:
- Primary label (object type): Tire / Cargo / Construction Waste / Other
- Secondary label (size classification): Small (longest side < 30 cm) / Medium (30–100 cm) / Large (> 100 cm)
- Tertiary label (danger level): Low-risk (disposal can be delayed) / Medium-risk (warning signs required) / High-risk (immediate clearance needed)
- Auxiliary annotation: Object bounding box coordinates

3. Model Selection and Initialization
A YOLOv9 + PointNet++ multimodal fusion model is adopted, with initialization of parameters and optimization of hyperparameters: dynamically adjusted learning rate of 0.001–0.0001, batch size of 16, and custom anchor box parameters adapted to special shapes such as elongated cargo.

4. Model Training
Distributed training is implemented based on PyTorch, with mixed-precision training (FP16) used to improve efficiency. Training duration is set, and data augmentation is applied to simulate complex scenarios, including effects such as motion blur, backlighting, and vehicle occlusion, as well as conditions like nighttime low lighting and rain/fog weather. An early stopping mechanism (patience=15) is set, and gradient clipping is applied with max_norm=1.0.

5. Model Evaluation
During model training, the validation set is used to adjust hyperparameters. After training is completed, model performance is evaluated on the test set. Evaluation metrics include:
- Basic metrics: mAP@0.5, false positive rate
- Scenario robustness test: Nighttime detection rate
