Phys.org  June 18, 2024 Existing methods for single-view 3D reconstruction with Neural radiance fields (NeRF) rely on either data prior to hallucinate views of occluded regions which may not be physically accurate, or shadows observed by RGB cameras which are difficult to detect in ambient light and low albedo backgrounds. A team of researchers in the US (MIT, industry) proposed using time-of-flight data captured by a single-photon avalanche diode to overcome these limitations models two-bounce optical paths with NeRF using lidar transient data for supervision. By leveraging the advantages of both NeRF and two-bounce light measured by lidar they reconstructed […]
