Target-free Extrinsic Calibration of Event-LiDAR Dyad using Edge Correspondences

Target-free Extrinsic Calibration of Event-LiDAR Dyad using Edge Correspondences

This paper proposes a novel method to calibrate the extrinsic parameters between a dyad of an event camera and a LiDAR without the need for a calibration board or other equipment. Our approach takes advantage of the fact that when an event camera is in motion, changes in reflectivity and geometric edges in the environment trigger numerous events, which can also be captured by LiDAR.

A New Stereo Fisheye Event Camera for Fast Drone Detection and Tracking

A New Stereo Fisheye Event Camera for Fast Drone Detection and Tracking

This paper presents a new compact vision sensor consisting of two fish eye event cameras mounted back to-back, which offers a full 360-degree view of the surrounding environment. We describe the optical design, projection model and practical calibration using the incoming stream of events, of the novel stereo camera, called SFERA.
