Hardware Optimization for Immersive Simulation & Photogrammetric Environment Generation – Authors: Jonathan Hawes (presenting) and Karl Rosenberger. Civilian and Department of Defense (DoD) organizations are leveraging immersive simulation to bring the furthest reaches of the globe to the front lines in training and preparedness. This effort to maximize training, and thus the capabilities that come with it, invokes difficulties when used in the field due to the size, weight, and power (SWaP) needed to rapidly reconstruct photogrammetric environments at the fidelities needed for soldiers or civilians to make real world decisions. Edge processing, like that done as part of a mobile operations center, typically overlooks purpose-built solutions in favor of a broader platform that may function adequately on a broad spectrum but doesn’t excel at any one task. With research and optimization in the hardware configuration used during processing, RAVE significantly decreased processing time while also decreasing the SWaP consumption of the system. The result is a Tower/4U (T4U) system employed directly with the user for training and operational use. The paper outlined issues, hardware and software processing benchmarks and data aggregation into a new system topology which offers server-grade reconstruction speeds in a workstation form factor. During I/ITSEC, both systems were on display with a screen comparing processing data configurations. Users were able to wear an HMD and virtually experience the real-world scenario data that was processed in a fraction of the time of traditional methods. This demonstration illustrated the mission-critical system performance and its potential infusion into the One World Terrain ecosystem.
