S7379 - V-PANE: Large-Scale, Real-Time Textured Surface Reconstruction From Lidar, GPS/IMU, and Video

Session Speakers
Session Description

Dive deep into the design and implementation of V-PANE (Virtual Perspectives Augmenting Natural Experience), a 5-GPU system that performs truncated signed distance function (TSDF)-based 360-degree textured surface reconstruction using lidar with fused infrared and visible-spectrum video and renders the results in real time. The vehicle-mounted system updates its 3D model continuously, and simultaneously writes to disk all volume and texture data as the vehicle moves through the environment, reading parts of the model back into GPU memory when necessary. Learn about the system's bus bandwidth management and heavily optimized GPU activities: lidar resampling, lidar integration, pixel ray casting, video frustum projection, frame buffer assembly, and image compression and decompression.
