Evaluating Panoramic 3D Estimation in Indoor Lighting Analysis
Zining Cheng Guanzhou Ji
This paper presents the use of panoramic 3D estimation in lighting
simulation. Conventional lighting simulation necessitates detailed modeling as
input, resulting in significant labor effort and time cost. The 3D layout
estimation method directly takes a single panorama as input and generates a
lighting simulation model with room geometry and window aperture. We evaluate
the simulation results by comparing the luminance errors between on-site High
Dynamic Range (HDR) photographs, 3D estimation model, and detailed model in
panoramic representation and fisheye perspective. Given the selected scene, the
results demonstrate the estimated room layout is reliable for lighting
simulation.
