How Much Depth Information can Radar Contribute to a Depth Estimation Model? [PDF]
, 2022 Recently, several works have proposed fusing radar data as an additional perceptual signal into monocular depth estimation models because radar data is robust against varying light and weather conditions. Although improved performances were reported in prior works, it is still hard to tell how much depth information radar can contribute to a depth ...
