2、数据预处理与标注：①对原始数据按7:2:1比例划分训练集/验证集/测试集；②采用多级标注体系：一级标签（排污口/正常）、二级标签（工业废水/生活污水/雨污混排等）、三级标签（隐蔽式/明渠/压力管道等）。③关联要素标注包含管径、水流状态、水体色度异常值等关键信息。
3、模型选择和初始化：采用YOLOv5预训练模型，并初始化模型参数，设置合理的超参数：学习率0.002-0.0001动态调整，批量大小16，锚框参数根据拍摄图像特征优化；同时集成注意力机制增强小目标检测能力。

The application scenarios of the image training data for the drone intelligent recognition algorithm model of river sewage outfalls mainly focus on improving the AI model's recognition ability and accuracy for river sewage outfalls. Through training with this dataset, the AI model can effectively support drones in accurately identifying sewage discharge scenarios such as industrial wastewater, domestic sewage, and mixed sewage and rainwater discharge. This dataset is based on geographic coordinates and a three-level annotation system, which can provide decision support for environmental law enforcement departments in monitoring and early warning, pollution source location, etc., and support the construction of an integrated intelligent water environment supervision network.

1. Data Source: The original data was collected and captured by self-owned intelligent drones, recording data such as image ID, collection time, file path, collection equipment, geographic coordinates, shooting altitude, environmental parameters, and bounding box groups. Data cleaning was conducted to ensure data quality.

2. Data Preprocessing and Annotation:
① Divide the original data into training set, validation set and test set at a ratio of 7:2:1;
② Adopt a multi-level annotation system: first-level labels (sewage outfall/normal), second-level labels (industrial wastewater, domestic sewage, mixed sewage and rainwater discharge, etc.), third-level labels (concealed type, open channel, pressure pipeline, etc.);
③ Annotate associated key information including pipe diameter, flow state, abnormal water color values and other critical details.

3. Model Selection and Initialization: Use the pre-trained YOLOv5 model, initialize the model parameters, and set reasonable hyperparameters: dynamically adjust the learning rate from 0.002 to 0.0001, set batch size to 16, optimize anchor box parameters according to the characteristics of captured images; meanwhile integrate attention mechanisms to enhance the detection capability for small targets.

4. Model Training: Implement distributed training using the PyTorch framework, set the training duration, adopt a transfer learning strategy, freeze the parameters of the underlying feature extraction layer, introduce Mosaic data augmentation to improve adaptability to complex scenarios, and set an early stopping mechanism (patience=15) to prevent overfitting.

5. Model Evaluation:
① Build a multi-dimensional evaluation system: basic metrics (mAP@0.5), nighttime detection rate, false positive rate, false negative rate;
② Set progressive testing: four-stage scenario tests including single sewage outfall → densely distributed pipe network area → water eutrophication area → flood-submerged area.

6. Model Optimization: Optimize the inference engine to ensure inference speed, and establish a regional feature database mechanism.
