End-to-End Learnable Geometric Vision by Backpropagating PnP Optimization
Bo Chen, Alvaro Parra, Jiewei Cao +2
Deep networks excel in learning patterns from large amounts of data. On the other hand, many geometric vision tasks are specified as optimization problems. To seamlessly combine de…
Satellite Pose Estimation with Deep Landmark Regression and Nonlinear Pose Refinement
Bo Chen, Jiewei Cao, Alvaro Parra +1
We propose an approach to estimate the 6DOF pose of a satellite, relative to a canonical pose, from a single image. Such a problem is crucial in many space proximity operations, su…
Visual SLAM: Why Bundle Adjust?
Álvaro Parra, Tat-Jun Chin, Anders Eriksson +1
Bundle adjustment plays a vital role in feature-based monocular SLAM. In many modern SLAM pipelines, bundle adjustment is performed to estimate the 6DOF camera trajectory and 3D ma…
A Practical Maximum Clique Algorithm for Matching with Pairwise Constraints
Álvaro Parra, Tat-Jun Chin, Frank Neumann +2
A popular paradigm for 3D point cloud registration is by extracting 3D keypoint correspondences, then estimating the registration function from the correspondences using a robust a…
