POWERED BY EIVA NAVISUITE
Voyis VSLAM
The VSLAM solution is a visual acquisition and visualization software for the Voyis’ Discovery Stereo camera that provides the operator with real-time data quality feedback on the survey data collection process. Most stereo cameras require post-processing to generate the finalized 3D model, making it difficult to know if survey goals were achieved relating to coverage, image quality, and image overlap. The VSLAM solution generates a 3D model of the inspection environment in real-time, executing tracking, and dense point cloud generation, throughout the survey acquisition.
System controls, a video stream, data quality metrics, and the 3D model are all effectively displayed in the integrated EIVA NaviSuite interface. This provides the operator with a visual representation of the target to understand coverage and tracking effectiveness, while augmenting piloting with 3D spatial awareness.
Defects can be detected in the real-time 3D model, enabling operators to collect more detail on areas of interest
Accurate vehicle localization and 3D data is generated for advanced autonomy like obstable avoidance and dynamic path planning
Low-latency video for GVI and piloting, stills images for inspection, and real-time 3D reconstruction for survey QC
Robust target tracking for periods of degraded image quality using tight IMU integration
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, including IMU data, vehicle navigation, and high-dynamic-range images.
This initiative combines the expertise of two Covelya Group organizations to develop a revolutionary inspection and survey package. 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. This synergy provides client with a new level of confidence in their visual survey operations.
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
Standard NaviSuite functionalities including 3D eventing, measurements, and integration with other data types
VISUAL SIMULTANEOUS LOCALIZATION AND MAPPING
How It Works?
Voyis VSLAM Powered by EIVA NAviSuite accepts stills images from the Discovery Stereo Camera, identifies features in the data, and tracks the features between sequential images captured.
Utilizing the change in perspective between images along with the accurate Discovery Stereo calibration, the software builds up a 3D model of the target while simultaneously tracking the position of the camera. The VSLAM solution effectively detects loops in the trajectory, identifying a feature previously observed, to enhance model accuracy and limit the accumulated error.
The result is a dense 3D point cloud that is built up in the viewer as the subsea vehicle scans the structure with the camera. This provides the survey operator with situational awareness, as well as the ability to validate they have achieved full target coverage. An accurate real-time model validates the data quality is sufficient to achieve survey goals.
