PL₁P - Point-line Minimal Problems under Partial Visibility in Three Views

no code implementations ECCV 2020 Timothy Duff, Kathlén Kohn, Anton Leykin, Tomas Pajdla

We present a complete classification of minimal problems for generic arrangements of points and lines in space observed partially by three calibrated perspective cameras when each line is incident to at most one point.

Learning to Solve Hard Minimal Problems

1 code implementation6 Dec 2021 Petr Hruby, Timothy Duff, Anton Leykin, Tomas Pajdla

The hard minimal problems arise from relaxing the original geometric optimization problem into a minimal problem with many spurious solutions.

Galois/monodromy groups for decomposing minimal problems in 3D reconstruction

no code implementations10 May 2021 Timothy Duff, Viktor Korotynskiy, Tomas Pajdla, Margaret H. Regan

We consider three classical cases--3-point absolute pose, 5-point relative pose, and 4-point homography estimation for calibrated cameras--where the decomposition and symmetries may be naturally understood in terms of the Galois/monodromy group.

Trifocal Relative Pose from Lines at Points and its Efficient Solution

1 code implementation23 Mar 2019 Ricardo Fabbri, Timothy Duff, Hongyi Fan, Margaret Regan, David da Costa de Pinho, Elias Tsigaridas, Charles Wampler, Jonathan Hauenstein, Benjamin Kimia, Anton Leykin, Tomas Pajdla

We present a new minimal problem for relative pose estimation mixing point features with lines incident at points observed in three views and its efficient homotopy continuation solver.
