Evaluating Panoramic 3D Estimation in Indoor Lighting Analysis
This addresses the time and effort costs in indoor lighting analysis for professionals, but it appears incremental as it evaluates an existing method rather than introducing a new one.
The paper tackles the problem of labor-intensive lighting simulation by using panoramic 3D estimation to generate models from single panoramas, showing that the estimated layout is reliable for simulation with results compared to on-site HDR photographs and detailed models.
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.
