Projective reconstruction of all visual primitives

摘要

We present a method to simultaneously reconstruct cameras, points, lines, degenerate quadrics and full-rank quadrics from a set of n uncalibrated views of a static scene. Our method is based on the use of Bundle Adjustment to refine an initial reconstruction. During the initialization stage, a novel algorithm was proposed for the conic outline correction in n views. Constrains derived from this algorithm were also integrated in the cost function of Bundle Adjustment to help preserve the right topology of the reconstructed quadrics.
