RCBEVDet: Radar-Camera Fusion in Bird's Eye View for 3D Object Detection [PDF]
Computer Vision and Pattern RecognitionThree-dimensional object detection is one of the key tasks in autonomous driving. To reduce costs in practice, low-cost multi-view cameras for 3D object detection are proposed to replace the expansive LiDAR sensors.

Simulation of hailstorm event using Mesoscale Model MM5 with modified cloud microphysics scheme [PDF]
Annales Geophysicae, 2008 Mesoscale model MM5 (Version 3.5) with some modifications in the cloud microphysics scheme of Schultz (1995), has been used to simulate two hailstorm events over Gangetic Plain of West Bengal, India. While the first event occurred on 12 March 2003 and

Multi-class Road User Detection with 3+1D Radar in the View-of-Delft Dataset
IEEE Robotics and Automation Letters, 2022 Next-generation automotive radars provide elevation data in addition to range-, azimuth- and Doppler velocity. In this experimental study, we apply a state-of-the-art object detector (PointPillars), previously used for LiDAR 3D data, to such 3+1D radar ...

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 ...

MetaRadar: Multi-target Detection for Reconfigurable Intelligent Surface Aided Radar Systems [PDF]
IEEE Transactions on Wireless Communications, 2022 As a widely used localization and sensing technique, radars will play an important role in future wireless networks. However, the wireless channels between the radar and the targets are passively adopted by traditional radars, which limits the ...
