Bayesian Filtering for Homography Estimation

IEEE Robotics and Automation Letters, 2023
This paper considers homography estimation in a Bayesian filtering framework using rate gyro and camera measurements. The use of rate gyro measurements facilitates a more reliable estimate of homography in the presence of occlusions, while a Bayesian ...

A semi-automated framework for homography estimation

Computer Graphics and Imaging / 798: Signal Processing, Pattern Recognition and Applications, 2013
Reliable estimation of the geometric transformation (homography)between different planes is a key step in a number of robotics applications. A common requirement is the homography estimation between a ground plane and a camera.

Multiple homography estimation with full consistency constraints [PDF]

2010 International Conference on Digital Image Computing: Techniques and Applications, 2010
A novel approach is presented to estimating a set of interdependent homography matrices linked together by latent variables. The approach allows enforcement of all underlying consistency constraints while accounting for the arbitrariness of the scale of ...

Unsupervised and interpretable track‐to‐track association based on homography estimation of radar bias

IET Radar, Sonar & Navigation
Track‐to‐track association methods based on machine learning and deep learning have greatly improved the association results, but the scope of application is limited by the poor interpretability and manual association labelling.

Deep homography estimation with pairwise invertibility constraint

, 2018
Recent works have shown that deep learning methods can improve the performance of the homography estimation due to the better features extracted by convolutional networks. Nevertheless, these works are supervised and rely too much on the labeled training
