📖 Overview
JHU-ULTRA-360 is collected at a University campus and aims to reconstruct and visualize the entire campus in 4D, with collected across the span of two years, where the video frames are calibrated with manual inspection and aligned to a consistent coordinate system.
Immersive Ground Acquisition: Both perspective and 360 panorama images on the ground level are collected and calibrated to facilitate immersive 3D reconstruction.
Large-Scale Calibration: Twelve academic buildings are collected across multiple elevations, camera models, and years, and are calibrated together.
TODO: update the calibration to RTK accuracy.
