Anti-Patterns to Avoid
需避免的反模式
1. "Single-Sensor Dependence"
1. "单传感器依赖"
Wrong: Using only RGB for fire detection.
Right: Multi-modal fusion (RGB + thermal) for high-confidence alerts.
| Detection Source | Confidence | Action |
|---|---|---|
| Thermal fire only | 70% | Alert + verify |
| RGB smoke only | 60% | Alert + investigate |
| Thermal + RGB | 95% | Confirmed fire |
错误做法：仅使用RGB进行火灾检测。
正确做法：多模态融合（RGB+热成像）以获得高置信度警报。
| 检测来源 | 置信度 | 行动 |
|---|---|---|
| 仅热成像火灾 | 70% | 警报+核实 |
| 仅RGB烟雾 | 60% | 警报+调查 |
| 热成像+RGB | 95% | 确认火灾 |
2. "Ignoring Hail Pattern"
2. "忽略冰雹模式"
Wrong: Counting damage without analyzing spatial distribution.
Right: True hail damage has RANDOM distribution. Linear or clustered patterns indicate other causes (foot traffic, age).
错误做法：仅统计损坏数量而不分析空间分布。
正确做法：真正的冰雹损坏具有随机分布特征。线性或集群模式表明其他原因（人为踩踏、老化）。
3. "Thermal Temperature Trust"
3. "盲目信任热成像温度"
Wrong: Using raw thermal values without calibration.
Right: Account for:
- Emissivity of materials (roof = 0.9-0.95)
- Atmospheric transmission (humidity, distance)
- Reflected temperature from surroundings
- Time of day (thermal lag)
错误做法：直接使用未校准的热成像数值。
正确做法：需考虑以下因素：
- 材料发射率（屋顶=0.9-0.95）
- 大气传输（湿度、距离）
- 周围环境的反射温度
- 时间（热滞后）
4. "3DGS Frame Overload"
4. "3DGS帧过载"
Wrong: Extracting every frame from drone video.
Right: Extract 2-3 fps with 80% overlap. More frames ≠ better reconstruction.
| Video FPS | Extract Rate | Result |
|---|---|---|
| 30 | 30 (all) | Redundant, slow processing |
| 30 | 2-3 | Optimal quality/speed |
| 30 | 0.5 | Insufficient overlap |
错误做法：提取无人机视频的每一帧。
正确做法：以2-3帧/秒的速率提取，重叠率80%。更多帧≠更好的重建效果。
| 视频帧率 | 提取速率 | 结果 |
|---|---|---|
| 30 | 30（全部） | 冗余、处理缓慢 |
| 30 | 2-3 | 质量/速度最优 |
| 30 | 0.5 | 重叠不足 |
5. "Insurance Claim Speculation"
5. "保险理赔猜测"
Wrong: Estimating costs without material identification.
Right: Identify material → Apply correct cost matrix.
| Material | Repair $/sqft | Replace $/sqft |
|---|---|---|
| Asphalt shingle | $5-10 | $3-7 |
| Metal | $10-15 | $8-14 |
| Tile | $12-20 | $10-18 |
| Slate | $20-40 | $15-30 |
错误做法：未识别材料就估算成本。
正确做法：先识别材料→应用正确的成本矩阵。
| 材料 | 维修费用 $/平方英尺 | 更换费用 $/平方英尺 |
|---|---|---|
| 沥青瓦片 | $5-10 | $3-7 |
| 金属 | $10-15 | $8-14 |
| 瓷砖 | $12-20 | $10-18 |
| 石板 | $20-40 | $15-30 |
6. "Defensible Space Zone Confusion"
6. "防护空间区域混淆"
Wrong: Treating all vegetation equally regardless of distance.
Right: CAL FIRE zones have different requirements:
| Zone | Distance | Requirement |
|---|---|---|
| 0 | 0-5 ft | Ember-resistant (no combustibles) |
| 1 | 5-30 ft | Lean, clean, green (spaced trees) |
| 2 | 30-100 ft | Reduced fuel (selective thinning) |
错误做法：不考虑距离，对所有植被一视同仁。
正确做法：CAL FIRE区域有不同要求：
| 区域 | 距离 | 要求 |
|---|---|---|
| 0 | 0-5英尺 | 抗余烬（无易燃物） |
| 1 | 5-30英尺 | 稀疏、整洁、常绿（树木间距合理） |
| 2 | 30-100英尺 | 减少燃料（选择性疏伐） |

保险工作流
1. Pre-Event Assessment (Underwriting)
├─ Satellite: Regional risk context
