How to Calibrate Your Event Camera

2021-05-26 · Manasi Muglikar, Mathias Gehrig, Daniel Gehrig, Davide Scaramuzza

We propose a generic event camera calibration framework using image reconstruction. Instead of relying on blinking LED patterns or external screens, we show that neural-network-based image reconstruction is well suited for the task of intrinsic and extrinsic calibration of event cameras. The advantage of our proposed approach is that we can use standard calibration patterns that do not rely on active illumination. Furthermore, our approach enables the possibility to perform extrinsic calibration between frame-based and event-based sensors without additional complexity. Both simulation and real-world experiments indicate that calibration through image reconstruction is accurate under common distortion models and a wide variety of distortion parameters

Event Camera as Region Proposal Network

2023-05-01 · Shrutarv Awasthi, Anas Gouda, Richard Julian Lodenkaemper, Moritz Roidl

The human eye consists of two types of photoreceptors, rods and cones. Rods are responsible for monochrome vision, and cones for color vision. The number of rods is much higher than the cones, which means that most human…

Event Camera Calibration of Per-pixel Biased Contrast Threshold

2020-12-17 · Ziwei Wang, Yonhon Ng, Pieter van Goor, Robert Mahony

Event cameras output asynchronous events to represent intensity changes with a high temporal resolution, even under extreme lighting conditions. Currently, most of the existing works use a single contrast threshold to es…
