Zupt's 3D modeling service is built around a robust 3D reconstruction methodology, enabling the creation of dense, georeferenced point clouds for a wide range of subsea applications. At the core of this capability is the 3D Recon system, a self-contained, 4,000-meter-rated solution that integrates high-accuracy inertial navigation with real-time 3D model generation.

This service leverages Visual-Inertial SLAM (Simultaneous Localization and Mapping), combining synchronized machine vision cameras with a tightly integrated MEMS inertial measurement unit (IMU). This approach allows for accurate navigation and spatial mapping in unknown subsea environments, even in the absence of external positioning references.

Key Features:

• Real-Time 3D Model Output: Supports sparse model generation during live operations. Enables faster decision-making during inspection, repair, maintenance (IRM), and construction support.
• High-Precision Navigation: Provides metrology-level spatial accuracy—achieving up to 30mm precision over 30 meters—delivering survey-grade results for dimensional control and intervention planning.
• Field-Ready Hardware: Built with a titanium housing and modular design, the system integrates seamlessly with work-class ROVs and survey multiplexers. Embedded processing allows for real-time data delivery offshore.
• Performance in Challenging Environments: Designed to operate in low-visibility or feature-poor areas, maintaining tracking performance even under degraded visual conditions.

Applications Include:

• Free span and pipeline surveys
• Digital twin creation for integrity management
• Dimensional control and as-built modeling
• Subsea navigation and positioning support
• Mooring, hull, and SPAR inspections

By combining real-time navigation with advanced 3D reconstruction, Zupt's modeling service enables rapid, spatially accurate deliverables—reducing offshore campaign time, improving safety, and lowering overall costs.
