LPVR-DUO
LPVR-DUO: In-Vehicle AR/VR Visualization Solution
Overview
LPVR-DUO is an in-car AR/VR tracking system that fuses inertial measurement data using a special predictive algorithm based on a head motion model.
Building on the technology we developed for our IMU sensors and large-scale VR tracking systems, we have created a full motion tracking and rendering pipeline for virtual reality (VR) and augmented reality (AR) applications. The LPVR middleware is a full solution for AR / VR that enables headset manufacturers to easily create a state-of-the-art visualization pipeline customized to their product.
The tracking backend of the LPVR middleware solution for VR and AR is especially advanced in the aspect that it allows the flexible combination of multiple optical systems and inertial measurement units (IMUs) for combined position and orientation tracking. Specifically, this in-car VR tracking system enables the de-coupling of the head motion of a user and the motion of a vehicle the user might be riding in, such as a car or airplane.
In this way the interior of a vehicle can be displayed as static relative to the user, while the scenery in the environment of the vehicle moves with vehicle motion. For any application of augmented reality or virtual reality application in a moving vehicle, this functionality is essential to provide an immersive experience to the user. LP-Research is the industry leader for providing customized sensor fusion solutions for augmented and virtual reality.
