Estimating 6D Aircraft Pose from Keypoints and Structures
Remote Sensing, 2021 This article addresses the challenge of 6D aircraft pose estimation from a single RGB image during the flight. Many recent works have shown that keypoints-based approaches, which first detect keypoints and then estimate the 6D pose, achieve remarkable ...

Rethinking of learning-based 3D keypoints detection for large-scale point clouds registration
International Journal of Applied Earth Observation and Geoinformation, 2022 The main solution for large-scale point clouds registration is to first obtain a set of matched 3D keypoint pairs and then accomplish the point cloud registration task based on these matched keypoint pairs.

Triangular Regions Representations for Matching Images With Viewpoint Changes
IEEE Access, 2022 This paper proposes triangular region representations based on keypoints detected in images with viewpoint changes. The strongest keypoints in the reference and query images are allocated individually using a previously published contourlet-based ...

Viewpoints and keypoints [PDF]
2015 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2015 We characterize the problem of pose estimation for rigid objects in terms of determining viewpoint to explain coarse pose and keypoint prediction to capture the finer details. We address both these tasks in two different settings - the constrained setting with known bounding boxes and the more challenging detection setting where the aim is to ...
