Pose and Motion Estimation Using Dual quaternion-based Extended Kalman Filtering

Quaternion Based Camera Pose Estimation From Matched Feature Points

We present a novel solution to the camera pose estimation problem, where rotation and translation of a camera between two views are estimated from matched feature points in the images. The camera pose estimation problem is traditionally solved via algorithms that are based on the essential matrix or the Euclidean homography. With six or more feature points in general positions in the space, ess...

Neuromorphic Event-Based 3D Pose Estimation

Pose estimation is a fundamental step in many artificial vision tasks. It consists of estimating the 3D pose of an object with respect to a camera from the object's 2D projection. Current state of the art implementations operate on images. These implementations are computationally expensive, especially for real-time applications. Scenes with fast dynamics exceeding 30-60 Hz can rarely be proces...

The event-camera dataset and simulator: Event-based data for pose estimation, visual odometry, and SLAM

New vision sensors, such as the Dynamic and Active-pixel Vision sensor (DAVIS), incorporate a conventional globalshutter camera and an event-based sensor in the same pixel array. These sensors have great potential for high-speed robotics and computer vision because they allow us to combine the benefits of conventional cameras with those of event-based sensors: low latency, high temporal resolut...

Event-triggered Feedback in Control, Estimation, and Optimization

Networked control systems often send information across the communication network in a periodic manner. The selected period, however, must assure adequate system performance over a wide range of operating conditions and this conservative choice may result in significant over-provisioning of the communication network. This observation has motivated the use of sporadic transmission across the net...
