The paper introduces a self-calibrating, fully differentiable non-line-of-sight (NLOS) inverse rendering pipeline for reconstructing hidden scenes. The pipeline uses only measured illumination and operates in both time and frequency domains. By extracting geometric information from NLOS volumetric intensities, it can estimate the time-resolved illumination at the relay wall. The pipeline optimizes imaging parameters by minimizing the error between simulated and measured illuminations. The method proves robust in consistently reconstructing geometry and albedo, even under high noise levels.
