## 设置模型

### 方式1: 符号链接（开发环境）
```bash
# 在项目根目录执行
ln -sf /path/to/fire_detection/models/best.pt models/fire_detection/
ln -sf /path/to/yolov/yolov8n.pt models/helmet_detection/
ln -sf /path/to/behavior_detection/Crowd-Gathering/models/yolov8l.pt models/crowd_detection/
ln -sf /path/to/behavior_detection/smoker-detection/models/smoking_yolov8n.pt models/smoking_detection/
ln -sf /path/to/behavior_detection/Loitering-Detection/yolov8n.pt models/loitering_detection/
```

### 方式2: 复制文件
```bash
cp /path/to/fire_detection/models/best.pt models/fire_detection/
cp /path/to/yolov/yolov8n.pt models/helmet_detection/
cp /path/to/behavior_detection/Crowd-Gathering/models/yolov8l.pt models/crowd_detection/
cp /path/to/behavior_detection/smoker-detection/models/smoking_yolov8n.pt models/smoking_detection/
cp /path/to/behavior_detection/Loitering-Detection/yolov8n.pt models/loitering_detection/
```

### 方式3: 使用初始化脚本
```bash
bash scripts/setup-models.sh
```
