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 and he is able to control all information displayed to the diver including the ability to show real-time 3D imagery of the divers environment in 1st or 3rd person perspective, regardless of the water visibility conditions facing the diver.

In addition to the provision of Mixed Reality (MR) scene awareness, the dive supervisor is able to communicate seamlessly via real-time images, videos, technical drawing, 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 effect the best outcome of the mission. The integration of the diver head tracker and low-light HD Camera further allow complete understanding of the Divers 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 computer aided instruction.

The DAVD system can be used either 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:

Visualize:

• 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
