1.数据采集
通过企业自有摄像设备自行采集道路排水口图像，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、过曝或严重遮挡图像。按6:2:2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：正常/异常
二级标签：完全堵塞/部分堵塞/结构损坏/异物覆盖/其他
辅助标注：堵塞区域边界框坐标、主要堵塞物类型（落叶/垃圾/泥沙等）、排水口类型
3.模型选择与初始化
采用Mask R-CNN实例分割模型，ResNet-50-FPN骨干网络，初始化参数并优化超参数：学习率0.01-0.001动态调整，批量大小1-16动态调整，锚框参数适配常见排水口形态；集成多尺度特征融合模块。
4.模型训练
基于PyTorch框架实施训练，采用混合精度训练（FP16）提升效率。设置训练时长，数据增强模拟不同水位状态，添加落叶、垃圾等遮挡物，模拟夜间低光照条件，设置早停机制（patience=12），使用OHEM处理样本不平衡问题。
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：
基础性能指标：mAP@0.5、误报率
场景鲁棒性测试：夜间检出率
并设置渐进式测试：单一堵塞→混合堵塞，明显堵塞→早期淤积

This dataset is primarily developed to improve the accuracy and capability of AI models in identifying abnormalities of urban road drainage systems. Through training on this dataset, AI models can accurately recognize abnormalities such as total blockage, partial blockage, structural damage and foreign matter coverage of drainage outlets via image analysis, and can be applied in scenarios including urban flood control management, municipal facility maintenance, intelligent traffic management and emergency management. Meanwhile, this dataset can provide intelligent monitoring means for flood control departments to prevent road waterlogging, provide waterlogging early warnings for traffic management departments, and allow emergency management departments to quickly locate high-risk drainage outlets, thereby comprehensively improving the operation and maintenance efficiency of urban drainage systems and emergency response capabilities, and effectively reducing economic losses caused by poor drainage.

1. Data Collection
Images of road drainage outlets are collected using the enterprise's own photographic equipment, while supporting data including image ID, collection time, device model, geographic coordinates, lighting conditions and weather conditions are synchronously recorded.

2. Data Preprocessing and Annotation
Blurry, overexposed or severely occluded images are removed through data cleaning. The dataset is split into training, validation and test sets at a ratio of 6:2:2. A multi-level annotation system is established:
- Primary label: "Normal/Abnormal"
- Secondary label: "Total blockage/Partial blockage/Structural damage/Foreign matter coverage/Others"
- Auxiliary annotations: Bounding box coordinates of blocked areas, main blockage types (fallen leaves/trash/sediment etc.), drainage outlet types

3. Model Selection and Initialization
The Mask R-CNN instance segmentation model with ResNet-50-FPN backbone network is adopted. Initialization parameters are set and hyperparameters are optimized: dynamically adjusted learning rate (0.01-0.001), dynamically adjusted batch size (1-16), anchor box parameters adapted to common drainage outlet shapes, and a multi-scale feature fusion module is integrated.

4. Model Training
Training is implemented based on the PyTorch framework, with mixed-precision training (FP16) adopted to enhance efficiency. Training duration is set, data augmentation is used to simulate different water level conditions, add occlusions such as fallen leaves and trash, simulate low-light nighttime conditions, an early stopping mechanism (patience=12) is configured, and OHEM (Online Hard Example Mining) is applied to address sample imbalance issues.

5. Model Evaluation
During the model training process, the validation set is used to adjust hyperparameters. After training is completed, model performance is evaluated on the test set. The evaluation metrics include:
- Basic performance metrics: mAP@0.5, False Positive Rate
- Scene robustness test: Nighttime detection rate
Progressive testing is also set up: Single blockage → Mixed blockage, Obvious blockage → Early siltation
