Indoor Heat Estimation from a Single Visible-Light Panorama
- 通过室内外HDR全景图推断光照与材质分布。
- 基于光热传递模型模拟出室内温度分布，与红外实测数据吻合。
- 适合做虚拟家居设计或建筑能耗分析的科研人员。
本文提出一种新型图像渲染技术，通过配对的室内外高动态范围（HDR）全景图，联合估计室内照明与热环境。利用室内全景图重建三维地板布局，对应室外全景图作为环境贴图，推断空间变化的光照与材料属性。假设室内表面为朗伯反射体，且所有热量源自室外可见光，建立光传输与热传导的关系，进行瞬态热仿真生成室内温度分布。模拟结果经红外相机采集的真实热成像数据验证。该方法支持物理驱动的逼真可视化，实现光照与热环境一体化估算，推动传统虚拟家装设计的发展。
原文摘要 · Abstract (English)
This paper introduces a novel image-based rendering technique for jointly estimating indoor lighting and thermal conditions from paired indoor-outdoor high dynamic range (HDR) panoramas. Our method uses the indoor panorama to estimate the 3D floor layout, while the corresponding outdoor panorama serves as an environment map to infer spatially-varying illumination and material properties. Assuming indoor surfaces are Lambertian and that all heat originates from outdoor visible light, we model the relationship between light transport and heat transfer, and perform transient heat simulations to generate indoor temperature distributions. The simulated heat maps are validated against real-world thermal images captured with an infrared camera. This approach supports photorealistic and physically informed visualization, enabling integrated light and heat estimation to advance traditional virtual home staging.
