GMMCalib: Extrinsic Calibration of LiDAR Sensors using GMM-based Joint Registration [PDF]

IEEE/RJS International Conference on Intelligent RObots and Systems
State-of-the-art LiDAR calibration frameworks mainly use non-probabilistic registration methods such as Iterative Closest Point (ICP) and its variants.

Mathematical models for geometric calibration of a hyperemispheric camera for planetary exploration [PDF]

, 2023
openHyperemispheric lenses belong to the ultra-wide field-of-view optical objectives. The lens considered was firstly introduced in 2018. Its field of view is 360° on the azimuth and 135° for the off-boresight angle.

More Accurate Pinhole Camera Calibration with Imperfect Planar Target

, 2011
This paper presents a novel approach to camera calibration that improves final accuracy with respect to standard methods using precision planar targets, even if now inaccurate, unmeasured, roughly planar targets can be used.

Lattice‐Matched 2D Template Enables Efficient Cesium Tin Halide Perovskite Solar Cells

Advanced Materials, EarlyView.
Lattice‐matched 2D perovskite PEA2CsSn2I7 templates the out‐of‐plane growth of inorganic 3D γ‐CsSnI3 along the (110) plane, forming highly oriented 2D/3D tin halide perovskite heterostructures. With reduced trap states and mitigated δ‐phase impurities, the CsSnI3‐based solar cells achieve a power conversion efficiency of 15.27% and maintain stable ...

Extrinsic Calibration of LiDAR and Camera using Multiple Traffic Sings

, 2021
For fusing accurate multimodal measurements, an external calibration of various sensors is required. Extrinsic transformations, on the other hand, can drift slowly when driving or maintaining, reducing the precision of the sensory system.

Automatic Multi-Sensor Extrinsic Calibration For Mobile Robots [PDF]

IEEE Robotics and Automation Letters, 2019
In order to fuse measurements from multiple sensors mounted on a mobile robot, it is needed to express them in a common reference system through their relative spatial transformations. In this paper, we present a method to estimate the full 6DoF extrinsic calibration parameters of multiple heterogeneous sensors (Lidars, Depth and RGB cameras) suitable ...
