Extended Data Fig. 1: The frustum-guided calibration design.
From: Glasses-free 3D display with ultrawide viewing range using deep learning
We leverage a frustum in 3D vision for calibration guidance, since it denotes the perspective viewing volume and describes the direction and extent of visible 3D space. Calibration is achieved when a precise alignment is observed, marked by the lines appearing darkest and thickest, indicating the ocular position aligns with the corresponding point in light-field space.
