东京都住宅供给公社：用系留红外无人机勘察一栋 32 层公共住宅楼的外立面
JKK 东京在江东区一栋 32 层公共住宅楼试验了系留红外无人机外墙勘察。裂缝和缺损检出良好，瓷砖空鼓大多能检出，但栏杆和密封胶的热量造成了误报。日照较弱的北立面无法验证，因此仍需后续敲击检查。
| 业主 | Tokyo Metropolitan Government (Toei housing), managed by Tokyo Metropolitan Housing Supply Corporation (JKK Tokyo) |
| 服务商 | — |
| 地点 | Toei Shinonome 2-chome No. 2 Apartments, Koto-ku, Tokyo, Japan |
| 机型 | Small drone (about 900 g) on a two-point tether system |
| 传感器 | thermal infrared, RGB camera |
引入前
约每 10 年对瓷砖外墙进行一次全面敲击检查，通常使用吊篮，而吊篮在 60–110 m 的高楼上往往不可行。
引入无人机后
2022年3月允许使用红外无人机的规则变更后，对四个立面的 23–32 层在距墙约 4 m 处飞行，五天内共 96 次飞行，采用两点系留、地面警戒区和观察员。
成果
| 指标 | 数值 | 依据 |
|---|---|---|
| survey effort | 5 flying days, 96 flights, 4 faces; seven-role crew | 报告值 |
| surface defects | chipping and cracks identified well in visible images, checked on site | 报告值 |
| tile delamination | generally detected from thermal differences, with some false positives on sound areas | 报告值 |
| accuracy / cost | not quantified | 报告值 |
注意事项与局限
- False positives were caused by sun-heated metal railings, black sealant and different heat storage in steel, rebar and precast elements; expert interpretation and follow-up tapping are still needed.
- The north face had no detected delamination, so weak-sun accuracy could not be validated.
- Single-building trial of public rental housing (not an owner-occupied condominium); rooftop louvres had to be removed to fix the tether, and flight plans must be tailored per building.
