基督城市议会：一天内用 LiDAR 无人机勘察约 265 m 的双线雨水管道
基督城市议会委托用 LiDAR 无人机测绘了约 265 m 的双排雨水管道。数据在一天内采集完成，无人进入管道。无人机测绘与 CCTV 结合使用而非取而代之，未给出成本数字。
| 业主 | Christchurch City Council (with AECOM as consultant) |
| 服务商 | InterGroup |
| 地点 | Christchurch, New Zealand |
| 机型 | Flyability Elios 3 with LiDAR payload and range extender |
| 传感器 | LiDAR, 4K camera, onboard lighting |
引入前
先高压水冲洗再做 CCTV 检测；对于这样的长度，需要数天工作并进入受限空间。
引入无人机后
无人机飞越 1,800 mm 和 1,200 mm 管道；带地理参考的点云和视频被导入 WinCan。
成果
| 指标 | 数值 | 依据 |
|---|---|---|
| data collection | 1 day vs likely multiple days for cleaning plus CCTV | 报告值 |
| length surveyed | 265.69 m (also given as 260 m / 265 m) | 报告值 |
| cost | described as more cost-effective, no figures | 报告值 |
注意事项与局限
- Manufacturer case study; year not stated; length is reported inconsistently.
- AECOM asked for the drone survey to be combined with CCTV, so it did not replace conventional pipe inspection.
- No cost data support the cost-effectiveness claim.
