Voyis is releasing the VSLAM version 1.3 in collaboration with EIVA, powered by EIVA NaviSuite, designed for real-time subsea mapping with 3D visualization through voxel-based rendering and stereo vision technologies.
Version 1.3 introduces a next-generation voxel-based 3D mapping engine, enabling real-time textured visualizations of inspection environments. By projecting the ROV camera’s field of view onto the real-time 3D map, operators gain a detailed view of subsea scenes, providing spatial context and supporting navigational decisions during visual inspections.
Augmented Real-Time Visualisation for Piloting Support
The new default visualization overlays the system’s real-time depth map onto a structured voxel-based 3D map. This creates a real-time projection of the camera’s field of view, allowing ROV pilots to see the camera’s position within the environment and adjust their trajectory to areas not yet inspected.
This interface can assist in more efficient movement, better scene coverage, and gap-filling, particularly in large or complex subsea structures such as pipelines, hulls, and infrastructure.
Voxel-Based Mapping: Precision, Speed, and Clarity
Version 1.3 features a real-time point cloud engine using voxel modeling with a minimum resolution of 2.5 cm. Voxels, volumetric pixels, structure the map into a uniform 3D grid that stores both spatial and visual data. This representation reduces noise by aggregating multiple stereo measurements within each voxel, addressing isolated outliers often found in raw point clouds.
In addition to cleaner visuals, the voxel format enables faster map updates and more reliable loop closures during relocalization, providing a smoother experience as the system adjusts for positional drift.
Chris Gilson, CEO of Voyis, commented, “This release transforms the way ROV pilots interact with real-time data. By embedding live video perspectives into a continuously updating voxel map, we’re providing pilots with the ability to navigate more intelligently, cover more ground, and reduce data gaps in their inspection workflows.”
Supporting ROV Operators with Actionable Data
With this release, ROV pilots can quickly identify data gaps in real time, allowing them to adjust their trajectory before resurfacing. This reduces the need for rework, improves inspection quality, and helps ensure thorough scene documentation on the first pass. Whether inspecting wide-area infrastructure or confined spaces, the VSLAM 1.3 solution provides users with real-time spatial awareness and a clear understanding of their inspection progress.
Availability
Voyis VSLAM Powered by EIVA NaviSuite 1.3 will be available globally to existing users starting in late July 2025. For further details or to request a demo, please contact Voyis.
The latest VSLAM capabilities will be demonstrated live at EIVA Demo Days on September 24–25, 2025, in Aarhus, Denmark. Representatives from both Voyis and EIVA will be on-site to showcase the system’s real-time voxel-based mapping and visual navigation features. This event provides an opportunity to see the technology in action and interact with the development teams.
