Display Inverse Rendering Dataset

Introduction

This dataset is created for display inverse rendering, including multi-light stereo images captured by polarization cameras, and GT geometry (pixel-aligned point cloud and surface normals) scanned by high-precision 3D scanner.

Structure

• DIR-basic: The basic version of the dataset released with the paper. It includes stereo polarized RAW images, RGB images from a reference view, and ground-truth surface normals and point clouds. All images are captured under a multi-light configuration projected through 16×9 superpixels on the display.

• DIR-pms: This dataset follows the DiLiGeNT format and has the same composition as DIR-basic. It provides multi-light RGB images from the reference view along with related information and the ground-truth normal maps.
