Stacy Witbeck：在美国 86 处铁路走廊现场进行标准化的无人机与地面实景采集
美国铁路承包商 Stacy Witbeck 已在 86 个铁路走廊施工现场统一采用无人机和地面实景采集。该公司称这减少了在长线路上的现场驾车巡查。时间和成本节省未量化，而且仅靠航拍采集无法记录轨道和平交道口的状况。
| 业主 | Transit agencies (not named) |
| 服务商 | Stacy Witbeck (heavy civil rail contractor) |
| 地点 | California, United States (e.g. Los Angeles Sixth Street Viaduct, Van Nuys Boulevard) |
| 机型 | DJI Mavic 3 Enterprise with RTK |
| 传感器 | RGB photogrammetry, ground 360° capture |
引入前
常规测量设备加大量驾车巡查，无法适应 30–150 英里的线路。
引入无人机后
110 名内部飞手飞行采集轨道线形、道口和物料堆场；从卡车进行的地面采集覆盖无人机看不到的轨道和平交道口状况。
成果
| 指标 | 数值 | 依据 |
|---|---|---|
| programme scale | 86 sites, 5,594 flights, 1,048 maps and 1,204 design overlays | 报告值 |
| ground mapping | about 30 miles mapped from a truck on one design-build job, avoiding designer site visits | 报告值 |
| time / cost / safety | not quantified | 报告值 |
注意事项与局限
- Software vendor (DroneDeploy) promotional story; no accuracy, cost or schedule baseline.
- This is construction-phase reality capture of rail corridors rather than condition inspection of operating track.
- Aerial capture alone could not document track and at-grade conditions; ground capture was required. Airspace and hardware rules are tight on large projects.
关于事后对素材进行精修与规范化处理，参见在 DaVinci Resolve 中完成航拍素材的后期（航拍指南内）。
每个现场的每日记录可以保存在记录天气、人员、作业与照片的现场日报。
