Diver Augmented Vision Display (DAVD)
Overview
The Diver Augmented Vision Display (DAVD) is a complete end-to-end diver management solution incorporating critically a high-resolution see-through head-up display (HUD) embedded directly inside the diving helmet.
The HUD is controlled from the surface by the Dive Supervisor using the supplied 4G Underwater Survey Explorer—"DAVD Edition" software suite. He is able to control all information displayed to the diver, including the ability to show real-time 3D imagery of the diver's environment in a first —or third-person perspective, regardless of the water visibility conditions facing the diver.
In addition to providing Mixed Reality (MR) scene awareness, the dive supervisor can communicate seamlessly via real-time images, videos, technical drawings, text-style messaging and step-by-step instructional sets. Effectively, the diver has complete on-demand access to all the technical data, know-how, and support from the team on the surface to achieve the best outcome for the mission. Integrating the diver head tracker and low-light HD Camera further allows a complete understanding of the diver's motion, head orientation, and immediate real-time working scene. Replacement of the diver legacy communication with digital audio allows clearer audio, noise reduction, and voice command assistance with computer-aided instruction.
The DAVD system can be used in "rapid" deployment scenarios where minimal prior information is known or scanned or in "Simulation and Planning" scenarios where a detailed prior 3D map of the scene is created and then annotated by the Diver and Supervisor. The latter scenario affords the greatest functionality and is particularly beneficial for repeat dives on a work site, such as a salvage operation, where data, information and spatial context can be built in real time and incorporated into the mission for subsequent dives. Through the use of the 4G Underwater Survey Explorer DAVD Edition software package and the supporting equipment, the diver can then receive a range of real-time display information, including:
Visualise:
Complete 3D Spatial Environment with Live or Pre-Survey Sonar data, 3D Models and Technical Data
3D Waypoints with direct navigation
Images, Videos and Billboards within the 3D view
Simulated dive of 3D environment before the diver enters the water
Communicate:
Text, Voice and Video messaging with the Dive Supervisor team
Navigation and Direction instruction and symbology
Dive Timer, Geo-Triggers and Alerts
Distances and ranges to targets and hazards
Dive Telemetry data - including position, heading and bearing, elapsed time and decompression profiles
Assist:
Live 3D measurements of assets and targets of interest
GEO Tagging information around Hazards or key targets
Complete Dive Supervisor interaction with visual content seen by Diver
Workflow management - comprehensive step-by-step task instruction management
Augmentation of the 3D scene with hazards, 3D models and technical data
Manage:
Provide any Technical data to the diver in real-time and on-demand
"How to" On-Demand Instruction and Reference Material
Collect, present and annotate the live scene or any images, photos and media
