1.数据采集​​
通过企业自有摄像设备自行采集道路路面井盖图像，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（井盖状态）：正常/缺失/破损
​​二级标签（破损类型）：碎裂（裂纹数量≥3条）/下沉（相对路面高度差≥2cm）/移位（水平偏移≥5cm）
​​三级标签（危险等级）：轻度（可延缓维修）/中度（需计划维修）/重度（立即处置）
​​辅助标注：破损或丢失区域边界框坐标
3.模型选择与初始化​​
采用YOLOv8-Pose（关键点检测）+ Mask R-CNN（实例分割）混合架构，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，自定义锚框参数适配常见井盖形态
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，数据增强模拟夜间、雨雪、树叶遮挡等干扰场景。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：雨雾天气检出率

This dataset is primarily intended to improve the recognition ability and accuracy of AI models for municipal manhole cover status. Training on this dataset allows AI models to accurately identify defects such as missing or damaged manhole covers, and can be applied to urban road safety inspection scenarios such as intelligent inspection vehicles and unmanned aerial vehicles (UAVs). Meanwhile, this dataset can provide data support for municipal facility management systems, helping to realize automatic recognition of manhole cover defects.
1. Data Collection
Manhole cover images on road surfaces are collected using the enterprise's own photographic equipment, with synchronized recording of data including image ID, capture time, device model, geographic coordinates, lighting conditions, and weather conditions.
2. Data Preprocessing and Annotation
Eliminate blurry and duplicate images through data cleaning. Split the dataset into training/validation/test sets at a ratio of 7:2:1, and establish a hierarchical annotation system:
- Primary label (manhole cover status): Normal / Missing / Damaged
- Secondary label (damage type): Fragmentation (number of cracks ≥ 3), Settlement (relative height difference from the road surface ≥ 2 cm), Displacement (horizontal offset ≥ 5 cm)
- Tertiary label (danger level): Mild (maintenance can be delayed), Moderate (scheduled maintenance required), Severe (immediate disposal needed)
- Auxiliary annotation: Bounding box coordinates of damaged or missing areas
3. Model Selection and Initialization
Adopt a hybrid architecture of YOLOv8-Pose (keypoint detection) + Mask R-CNN (instance segmentation), initialize parameters and optimize hyperparameters: dynamically adjust the learning rate within 0.001-0.0001, dynamically adjust the batch size within 1-32, and customize anchor box parameters to adapt to common manhole cover shapes.
4. Model Training
Implement distributed training based on PyTorch, using mixed-precision training (FP16) to improve efficiency. Set training duration, and apply data augmentation to simulate interference scenarios such as nighttime, rain/snow, and leaf occlusion. Set up an early stopping mechanism (patience=15) and gradient clipping with max_norm=1.0.
5. Model Evaluation
During the model training process, use the validation set to adjust hyperparameters. After training is completed, evaluate the model performance on the test set. The evaluation metrics include:
- Basic performance: mAP@0.5, false positive rate
- Scene robustness test: Detection rate in foggy and rainy conditions
