RadarCam-Depth: Radar-Camera Fusion for Depth Estimation with Learned Metric Scale

ICRA 2024poster

We present a novel approach for metric dense depth estimation based on the fusion of a single-view image and a sparse, noisy Radar point cloud. The direct fusion of heterogeneous Radar and image data, or their encodings, tends to yield dense depth maps with significant artifacts, blurred boundaries,…

CLINS: Continuous-Time Trajectory Estimation for LiDAR-Inertial System

IROS 2021poster

In this paper, we propose a highly accurate continuous-time trajectory estimation framework dedicated to SLAM (Simultaneous Localization and Mapping) applications, which enables fuse high-frequency and asynchronous sensor data effectively. We apply the proposed framework in a 3D LiDAR-inertial syste…

Targetless Calibration of LiDAR-IMU System Based on Continuous-time Batch Estimation

IROS 2020poster

Sensor calibration is the fundamental block for a multi-sensor fusion system. This paper presents an accurate and repeatable LiDAR-IMU calibration method (termed LI-Calib), to calibrate the 6-DOF extrinsic transformation between the 3D LiDAR and the Inertial Measurement Unit (IMU). Regarding the hig…
