外文摘要：We proposed a hybrid imaging scheme to estimate a high-resolution absolute depth map from low photon counts.It leverages measurements of photon arrival times from a single-photon LiDAR and an intensity image from a conventional high-resolution camera.Using a tailored fusion algorithm,we jointly processed the raw measurements from both sensors and output a high-resolution absolute depth map.We scaled up the resolution by a factor of 10,achieving 1300 x 2611 pixels and extending～4.7 times the unambiguous range.These results demonstrated the superior capability of long-range high-resolution 3D imaging without range ambiguity.
