Iterative Camera-LiDAR Extrinsic Optimization via Surrogate Diffusion
Ni Ou, Zhuo Chen, Xinru Zhang +1
Cameras and LiDAR are essential sensors for autonomous vehicles. Camera-LiDAR data fusion compensate for deficiencies of stand-alone sensors but relies on precise extrinsic calibra…
TransForce: Transferable Force Prediction for Vision-based Tactile Sensors with Sequential Image Translation
Zhuo Chen, Ni Ou, Xuyang Zhang +1
Vision-based tactile sensors (VBTSs) provide high-resolution tactile images crucial for robot in-hand manipulation. However, force sensing in VBTSs is underutilized due to the cost…
Marker or Markerless? Mode-Switchable Optical Tactile Sensing for Diverse Robot Tasks
Ni Ou, Zhuo Chen, Shan Luo
Optical tactile sensors play a pivotal role in robot perception and manipulation tasks. The membrane of these sensors can be painted with markers or remain markerless, enabling the…
Deep Domain Adaptation Regression for Force Calibration of Optical Tactile Sensors
Zhuo Chen, Ni Ou, Jiaqi Jiang +1
Optical tactile sensors provide robots with rich force information for robot grasping in unstructured environments. The fast and accurate calibration of three-dimensional contact f…
