The application scenarios of the image training data for the UAV-based intelligent photovoltaic panel defect recognition algorithm model mainly focus on improving the AI model's recognition capability and accuracy for photovoltaic panel defects. Trained on this dataset, the AI model can effectively enable UAVs to accurately recognize various defect types including hot spot effect, hidden crystalline silicon cracks, and surface contamination. This dataset is built on geographic coordinates and a two-level annotation system. It can be linked with SCADA system data to automatically generate operation and maintenance (O&M) work orders and mark the geographic coordinates of abnormal components, forming an intelligent O&M closed-loop of "monitoring-diagnosis-maintenance", which meets the all-weather efficient inspection needs of new energy power stations in complex terrains and various climatic conditions.

1. Data Source: The original data is collected via self-developed intelligent UAVs. Collected data includes image ID, collection time, file path, acquisition equipment, geographic coordinates, shooting altitude, environmental parameters, bounding box groups, etc. Data cleaning is performed to ensure data quality.

2. Data Preprocessing and Annotation:
① The original data is divided into training set, validation set and test set at a ratio of 7:2:1;
② A multi-level annotation system is adopted: the first-level labels include hot spot, hidden crack, contamination and normal; the second-level labels include (local hot spot / overall hot spot, micro-crack / structural fracture, local contamination / overall contamination).
③ Annotated associated elements include key information such as junction box location and shadow occlusion.

3. Model Selection and Initialization: The pre-trained YOLOv5 model is adopted, with model parameters initialized and reasonable hyperparameters set: dynamically adjusted learning rate of 0.002 to 0.0001, batch size of 16, anchor box parameters optimized based on the characteristics of captured images; meanwhile, an attention mechanism is integrated to enhance small-object detection capability.

4. Model Training: Distributed training is implemented using the PyTorch framework, with training duration set. A transfer learning strategy is adopted, where the parameters of the underlying feature extraction layers are frozen. Mosaic data augmentation is introduced to improve adaptation to complex scenarios, and an early stopping mechanism (patience=15) is set to prevent overfitting.

5. Model Evaluation:
① A multi-dimensional evaluation system is constructed, including basic metrics (mAP@0.5), nighttime detection rate, false positive rate, and false negative rate.
② Progressive testing is set up, which includes four stages: single-panel detection → string analysis → array scanning → complex terrain testing.

6. Model Optimization: The inference engine is optimized to ensure inference speed, and a regional feature database mechanism is established.
