Virtual Home Staging: Inverse Rendering and Editing an Indoor Panorama under Natural Illumination
This addresses the problem of virtual home staging for real estate or design applications, but it is incremental as it builds on existing inverse rendering and HDR techniques.
The paper tackles the problem of transforming indoor panoramas with new furniture layouts under natural illumination by proposing an inverse rendering method, resulting in a workflow demonstrated for different outdoor conditions and a new dataset of 137 calibrated HDR panoramas.
We propose a novel inverse rendering method that enables the transformation of existing indoor panoramas with new indoor furniture layouts under natural illumination. To achieve this, we captured indoor HDR panoramas along with real-time outdoor hemispherical HDR photographs. Indoor and outdoor HDR images were linearly calibrated with measured absolute luminance values for accurate scene relighting. Our method consists of three key components: (1) panoramic furniture detection and removal, (2) automatic floor layout design, and (3) global rendering with scene geometry, new furniture objects, and a real-time outdoor photograph. We demonstrate the effectiveness of our workflow in rendering indoor scenes under different outdoor illumination conditions. Additionally, we contribute a new calibrated HDR (Cali-HDR) dataset that consists of 137 calibrated indoor panoramas and their associated outdoor photographs.
