POWERED BY EIVA NAVISUITE
Voyis VSLAM
Voyis VSLAM Powered by EIVA NaviSuite is a real-time visual acquisition and visualization tool for the Voyis Discovery Stereo Camera, giving ROV operators immediate feedback on survey data quality. Unlike traditional stereo systems that rely on post-processing, the VSLAM solution builds a 3D reconstruction live during acquisition, helping teams ensure they’re meeting coverage and image quality goals.
With new updates, the system now delivers real-time textured 3D visualizations using a voxel-based model – an industry first. This shift from point clouds improves clarity by revealing textures and contours as the inspection progresses, making it easier to spot gaps and fill them efficiently.
System controls, low-latency video, data metrics, and the textured 3D model are all integrated in the EIVA NaviSuite interface, enhancing pilot awareness and streamlining survey execution.

Combined delivery of video, stills, and 3D data for underwater inspection quality control
VSLAM UPDATES
Geo-Located Mapping
This technical advancement brings absolute geo-located mapping to real-time camera-based 3D reconstruction for subsea inspection and metrology. This new capability enables VSLAM-generated point clouds to be projected directly into global coordinates, from the moment an inspection mission begins.
This marks the first time that real-time visual mapping is natively aligned to global geodetic frames, bridging the gap between camera-based navigation and established industry survey standards.
Voyis VSLAM Powered by EIVA NaviSuite reads the initial global position from a connected INS, such as a Sonardyne SPRINT-Nav, and places the map into the selected geodetic frame at mission start. This global placement is preserved throughout the dive, even after relocalisation or loop closure events. While the VSLAM engine continues refining local map geometry, its global alignment remains stable.
VOYIS & EIVA
Powerful Collaboration
Voyis VSLAM Powered by EIVA NaviSuite is provided exclusively by Voyis for the Discovery Stereo, and interfaces directly with EIVA NaviSuite software to ensure a seamless data integration with wider survey operations. A tight integration between both software and hardware ensures that all available survey data is effectively leveraged in 3D reconstruction.
This initiative combines the expertise of two Covelya Group organizations: Voyis’ hardware expertise in supplying the highest quality calibrated image data is united with EIVA’s survey navigation, acquisition, processing and visualisation software, providing customers with an optimized workflow, data management tools, integrated into the NaviSuite toolbox.
Survey operators and pilots can use a common interface for both piloting and data acquisition
Low-latency video is combined with ROV visualization in the 3D environment, enabling augmented piloting and trajectory monitoring
Integrated Discovery Stereo acquisition controls combined with survey metrics including standoff distance and survey speed
VISUAL SIMULTANEOUS LOCALIZATION AND MAPPING
How It Works?
Voyis VSLAM Powered by EIVA NaviSuite processes stills images from the Discovery Stereo Camera, identifying and tracking features between sequential images to simultaneously reconstruct the environment and estimate the camera’s trajectory.
By leveraging stereo image calibration and shifts in perspective, the software generates a live 3D model of the structure as it is surveyed. The system automatically recognizes when previously observed features reappear, enhancing both the visual model accuracy and the navigation path.
In the newest version, this dense point cloud output has evolved into a real-time textured 3D voxel model, giving operators a clearer and more realistic view of the inspection scene. This augmented visualization enables ROV pilots to validate coverage with confidence, navigate with increased spatial awareness, and act immediately on identified gaps or anomalies.
The result is an accurate, continuous 3D model that ensures survey goals are being met, minimizing rework and maximizing mission success.
