约翰内斯堡：街道燃气爆炸后用 LiDAR 无人机勘察地下管线隧道
2023年7月，约翰内斯堡市中心一条街道下方发生爆炸，损坏了地下管线隧道和管沟。Delta Scan 让搭载 LiDAR 和热成像相机、带保护笼的无人机穿过狭小开口，记录了人员无法进入处的损毁情况。所述作业时长前后不一，烟雾、灰尘和黑暗也妨碍了作业。
| 业主 | City of Johannesburg / emergency authorities |
| 服务商 | Delta Scan |
| 地点 | Lilian Ngoyi Street, Johannesburg CBD, South Africa |
| 机型 | Flyability Elios 3 with LiDAR payload; other drones for aerial imagery |
| 传感器 | LiDAR, visual camera, thermal camera (to check live cables), lighting rig |
引入前
先确保现场安全再进行常规检查，据称需要数周或数月。
引入无人机后
2023年7月爆炸后，无人机经小至 50×50 cm 的开口进入管线隧道，用 LiDAR 和热成像测绘损毁和空洞。
成果
| 指标 | 数值 | 依据 |
|---|---|---|
| duration | data collection about one week (the page also says the project took a few days) vs weeks or months | 报告值 |
| use of results | findings used by the city to plan rebuilding of the tunnels | 报告值 |
注意事项与局限
- Manufacturer case study; duration is stated inconsistently.
- Smoke, dust, debris and darkness hampered the work; success was partly credited to pilot skill.
- The cause (gas pipeline vs other) is not confirmed in the source.
