Medic Web31 aug. 2024 · A by pass would be, that given 2 line, you'd use a finites sample of point on the lines to calculate the Homography. To derive the Homography given lines, the Math goes by: Consider a line l which obeys for any point x ∈ l that x T l = 0 ⇔ l T x = 0. On the same manner consider a line on the other image such that x ′ T l ′ = 0 ⇔ l ′ T x ′ = 0.
