1.数据采集
通过企业自有摄像设备自行采集道路火灾图像，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：正常/火灾事件
二级标签：车辆自燃/货物燃烧/其他火源
辅助标注：火源边界框坐标、烟雾区域边界框坐标。
3.模型选择与初始化
采用YOLOv8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1-16动态调整，锚框参数适配火焰及烟雾特征；集成热成像分析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，数据增强模拟复杂场景，添加动态模糊、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。

基础性能指标：mAP@0.5、误报率
场景鲁棒性测试：夜间火灾检出率
并设置渐进式测试：小型火情→大型火灾，单一火源→多火源复合场景

This dataset is primarily designed to enhance the recognition accuracy and capability of AI models for sudden road fire incidents. Through training on this dataset, AI models can accurately identify sudden fire situations such as vehicle spontaneous combustion and cargo combustion, and can be applied to emergency monitoring scenarios in key traffic areas including expressways, urban main roads, and tunnels. Meanwhile, this dataset can provide decision-making support for the construction of smart cities such as urban fire early warning systems and emergency response mechanisms, thereby improving public safety prevention and control capabilities.

1. Data Collection
Road fire images are independently collected using the enterprise's own camera equipment, with simultaneous recording of data such as image ID, collection time, equipment model, geographic coordinates, lighting conditions, and weather conditions.

2. Data Preprocessing and Annotation
First, perform data cleaning to eliminate blurry and duplicate images. Divide the dataset into training set, validation set, and test set at a ratio of 7:2:1. Establish a multi-level annotation system:
- Primary label: Normal / Fire Incident
- Secondary label: Vehicle Spontaneous Combustion / Cargo Combustion / Other Fire Sources
- Auxiliary annotations: Coordinates of fire source bounding box, coordinates of smoke area bounding box.

3. Model Selection and Initialization
Adopt the pre-trained YOLOv8 model, initialize parameters and optimize hyperparameters: dynamically adjust the learning rate within 0.001-0.0001, dynamically adjust the batch size within 1-16, adapt anchor box parameters to the features of flames and smoke; integrate a thermal imaging analysis module to improve recognition accuracy.

4. Model Training
Implement distributed training based on PyTorch, adopt mixed precision training (FP16) to improve efficiency. Set training duration, use data augmentation to simulate complex scenarios, add effects such as dynamic blur and obstacle occlusion to simulate low-light nighttime and rainy/foggy weather conditions. Set an early stopping mechanism (patience=15) and gradient clipping (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 metrics: mAP@0.5, false positive rate
- Scenario robustness test: nighttime fire detection rate
And set progressive testing: small-scale fire → large-scale fire, single fire source → multi-fire source composite scenario.
