? Equipment Used

Deep Trekker’s REVOLUTION and

PIVOT ROVs were used in conjunction to provide extended battery life to last through the whole workday. Equipped with six thrusters, rotating camera heads, and tool platforms, they facilitat- ed lateral and vertical movements with- out adjusting pitch.

? Phase 1: Imaging

Facing challenges like Canadian win- ter conditions and dam-related risks,

Stantec used ROVs to conduct a quick- er underwater survey than traditional methods. The team captured extensive photo coverage by ? eld-swapping be- tween two vehicles in a grid pattern.

? Phase 2: Modeling

After capturing the necessary imagery, the team uploaded ? ndings to generate photogrammetric models using photo- grammetry software. Interactive models with millimetric accuracy were created, allowing comparisons against historical documents to track environmental im- pacts over time.

Key Takeaways

Using Deep Trekker ROVs, Stantec quickly, safely, and easily captured all modeling photos in a single day. ROVs empowered archaeologists to direct ve- hicles precisely, avoiding the need for extensive communication with a dive team. The result: high-detail 3D pho- togrammetric models of Nassau Mills dam without risks or repeating costs.
