OpenGV 2.0: Motion prior-assisted calibration and SLAM with vehicle-mounted surround-view systems
Kun Huang, Yifu Wang, Si'ao Zhang +4
The present paper proposes optimization-based solutions to visual SLAM with a vehicle-mounted surround-view camera system. Owing to their original use-case, such systems often only…
Cross-Modal Semi-Dense 6-DoF Tracking of an Event Camera in Challenging Conditions
Yi-Fan Zuo, Wanting Xu, Xia Wang +2
Vision-based localization is a cost-effective and thus attractive solution for many intelligent mobile platforms. However, its accuracy and especially robustness still suffer from…
Revisiting Event-based Video Frame Interpolation
Jiaben Chen, Yichen Zhu, Dongze Lian +7
Dynamic vision sensors or event cameras provide rich complementary information for video frame interpolation. Existing state-of-the-art methods follow the paradigm of combining bot…
Cross-modal Place Recognition in Image Databases using Event-based Sensors
Xiang Ji, Jiaxin Wei, Yifu Wang +2
Visual place recognition is an important problem towards global localization in many robotics tasks. One of the biggest challenges is that it may suffer from illumination or appear…
Globally-Optimal Contrast Maximisation for Event Cameras
Xin Peng, Ling Gao, Yifu Wang +1
Event cameras are bio-inspired sensors that perform well in challenging illumination conditions and have high temporal resolution. However, their concept is fundamentally different…
Globally-Optimal Event Camera Motion Estimation
Xin Peng, Yifu Wang, Ling Gao +1
Event cameras are bio-inspired sensors that perform well in HDR conditions and have high temporal resolution. However, different from traditional frame-based cameras, event cameras…
DEVO: Depth-Event Camera Visual Odometry in Challenging Conditions
Yi-Fan Zuo, Jiaqi Yang, Jiaben Chen +3
We present a novel real-time visual odometry framework for a stereo setup of a depth and high-resolution event camera. Our framework balances accuracy and robustness against comput…
Accurate calibration of multi-perspective cameras from a generalization of the hand-eye constraint
Yifu Wang, Wenqing Jiang, Kun Huang +2
Multi-perspective cameras are quickly gaining importance in many applications such as smart vehicles and virtual or augmented reality. However, a large system size or absence of ov…
Dynamic Event Camera Calibration
Kun Huang, Yifu Wang, Laurent Kneip
Camera calibration is an important prerequisite towards the solution of 3D computer vision problems. Traditional methods rely on static images of a calibration pattern. This raises…
Visual Odometry with an Event Camera Using Continuous Ray Warping and Volumetric Contrast Maximization
Yifu Wang, Jiaqi Yang, Xin Peng +5
We present a new solution to tracking and mapping with an event camera. The motion of the camera contains both rotation and translation, and the displacements happen in an arbitrar…
