NaviSuite VSLAM software comes standard with Voyis’ Discovery Stereo camera in a total solution 

... for seamless survey data acquisition, ROV piloting, quality control displays and camera control during visual inspections – all in the NaviSuite user interface

Voyis VSLAM Powered by EIVA NaviSuite is a computer vision software product which generates real-time QC displays of area coverage such as 3D point cloud and trajectory plot – using only your Discovery Stereo camera for input. The result is improved survey quality assurance during acquisition, as well as enhanced ROV visual inspection results by linking high-quality stills with true-scale 3D point clouds in real time.

Optimal acquisition with augmented ROV piloting

To minimise the risk of incomplete or inaccurate data collection, ROV pilots can look at real-time 3D point clouds and evaluate what was covered, as well as where to go next. For example, noise in trajectory plot data or holes in your point cloud will alert you to low quality data, and you can take action immediately, minimising time spent on re-survey. 
 
The real-time displays of trajectory plot also supplement navigation sensor setups for pilot situational awareness, such as sonar, enhancing your existing camera’s capabilities.

Streamlines your workflow when combined with NaviSuite software

No third-party software required – with Voyis VSLAM Powered by EIVA NaviSuite, your Discovery Stereo camera control, survey data acquisition, ROV piloting and surveying displays are all available on the topside computer. Surveyors using NaviPac Pro can benefit from the VSLAM solution’s seamless integration with their current navigation and control software user interface – in which you can register observations, take snapshots, as well as load background maps and 3D models. This helps you achieve a more streamlined workflow for efficient survey data acquisition.
 
During post-processing, the detailed 3D point cloud generated by the NaviSuite VSLAM software can be used as input to…
  • Third-party photogrammetry applications for generating a textured mesh
  • Data modelling software NaviModel for quantifiable change detection, measurement analysis and touchless metrology tools
In addition to the features included in this initial release of Voyis VSLAM Powered by EIVA NaviSuite, we will continue to develop more capabilities for future releases. Features we are developing to enable autonomous visual inspections include automated target recognition and tracking.
 
Please note: Each purchase of the Discovery Stereo Camera includes a one-year subscription licence to Voyis VSLAM Powered by EIVA NaviSuite.

    Quality control and situational awareness

    Want to optimally ensure comprehensive and accurate data collection? During visual inspections, Voyis VSLAM Powered by EIVA NaviSuite lets you display 3D point clouds and trajectory plots generated in real-time – alongside your RGB-D camera stills. With this, QC engineers can thoroughly evaluate the survey's coverage and identify any potential areas where data may be missing or insufficient. For example, if there is noise in the trajectory data or blank spaces in the point cloud, you can take corrective actions promptly, such as conducting additional scans or adjusting survey parameters.

    Monitor displays in an intuitive user interface

    Tailor your data display to suit your needs, whether piloting an ROV or performing quality control. You can customise the NaviSuite VSLAM software interface with several synchronised views, such as an overview map, RGB-D camera stills, video and 3D point cloud – of which you can create multiple 2D/3D views.

    Integration with Discovery Stereo

    Ensure high performance on a small form factor unit. Voyis’ Discovery Stereo camera’s edge computing reduces topside software computation and system latency, ensuring high-quality stills used by Voyis VSLAM Powered by EIVA NaviSuite. Camera outputs are partly processed in onboard software, yielding RGB-D images, rectified stereo pairs (aligned for ease of use in computer vision and metrology applications) and low latency video. 

    NaviSuite VSLAM algorithms are pre-calibrated to the camera and run directly on images as they are taken. Data is compressed before being sent to the topside computer, which greatly reduces bandwidth requirements and enables real-time video for the pilot display.

    What is VSLAM?

    How the VSLAM algorithm works

    Voyis VSLAM Powered by EIVA NaviSuite estimates the camera's position by analysing consecutive input frames and finding matching key points to determine camera movement between poses. It leverages previous trajectory knowledge to enhance estimations. It detects loops in camera movement and optimises previous poses for improved accuracy.
