Can be found as line intersections of plane But having all those point on a plane (in 3D) dont know how to convert them into 2D (to get that trapezoid in XY): And how to convert image (pixels position) having that trapezoid?

Web24 apr. 2024 · This short piece describes equations for estimating a 3 × 3 homography matrix. We first discuss the computation from intrinsic and extrinsic camera parameters; … WebWide-baseline street image interpolation is useful but very challenging. Existing approaches either rely on heavyweight 3D reconstruction or computationally intensive deep networks. We present a lightweight and efficient method which uses simple homography computing and refining operators to estimate piecewise smooth homographies between input views.
