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：坑洼/裂缝/正常
​​二级标签：轻度（<2cm深）/中度（2-5cm）/重度（>5cm）
​​三级标签：横向裂缝/纵向裂缝/网状裂缝/块状裂缝
​​辅助标注：边界框坐标、裂缝像素面积、车道线相对位置
3.模型选择与初始化​​
采用YOLOv8s预训练模型，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1-32动态调整，锚框参数适配坑洼裂缝形态；集成形态估计模块提升识别准确率。
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，数据增强模拟逆光、积水反光等干扰情况，添加遮挡物干扰等特效，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：
基础性能：mAP@0.5、误报率
场景鲁棒性测试：雨天检出率

This dataset is primarily designed to enhance the recognition capability and accuracy of AI models for road surface defects such as potholes and cracks. Training on this dataset enables AI models to automatically classify and evaluate road defects including potholes and cracks, and can be applied to regular inspection and preventive maintenance of highways, municipal roads, bridges and tunnels. Meanwhile, this dataset can support decision optimization and resource scheduling for road maintenance departments, and help vehicle-mounted inspection systems and UAV inspection platforms realize disease geotagging, damage grading and maintenance priority assessment.
1. Data Collection
Road surface images are collected independently using the enterprise's own camera equipment, while data such as image ID, collection time, equipment model, geographic coordinates, lighting conditions and weather conditions are recorded synchronously.
2. Data Preprocessing and Annotation
Blurred and duplicate images are eliminated through data cleaning. The dataset is divided into training set, validation set and test set at a ratio of 7:2:1. A multi-level annotation system is established:
- Primary labels: Pothole / Crack / Normal
- Secondary labels: Mild (<2cm depth) / Moderate (2-5cm) / Severe (>5cm)
- Tertiary labels: Transverse crack / Longitudinal crack / Network crack / Block crack
- Auxiliary annotations: Bounding box coordinates, crack pixel area, relative position of lane lines
3. Model Selection and Initialization
The pre-trained YOLOv8s model is adopted, with initialization parameters and optimized hyperparameters: dynamically adjusted learning rate of 0.001-0.0001, dynamically adjusted batch size of 1-32, anchor box parameters adapted to the morphology of potholes and cracks; a morphology estimation module is integrated to improve recognition accuracy.
4. Model Training
Distributed training is implemented based on PyTorch, and mixed-precision training (FP16) is adopted to improve efficiency. Training duration is set, and data augmentation is used to simulate interference conditions such as backlight and water accumulation reflection, plus effects such as obstacle occlusion, to simulate nighttime low-light and rainy/foggy weather conditions. An early stopping mechanism (patience=15) and gradient clipping (max_norm=1.0) are set.
5. Model Evaluation
During model training, the validation set is used to adjust hyperparameters. After training is completed, the model performance is evaluated on the test set. The evaluation metrics include:
- Basic performance: mAP@0.5, false positive rate
- Scene robustness test: Detection rate in rainy weather
