Web21 aug. 2024 · A homography, is a matrix that maps a given set of points in one image to the corresponding set of points in another image. The homography is a 3x3 matrix that maps each point of the first image to the corresponding point of the second image. See below where H is the homography matrix being computed for point x1, y1 and x2, y2 The homography can be estimated using for instance the Direct Linear Transform (DLT) algorithm (see 1 for more information). As the object is planar, the transformation between points expressed in the object frame and projected points into the image plane expressed in the … Meer weergeven The homography relates the transformation between two planes and it is possible to retrieve the corresponding camera displacement that allows to go from the first … Meer weergeven In this example, a source image will be transformed into a desired perspective view by computing the homography that maps the … Meer weergeven OpenCV 3 contains the function cv::decomposeHomographyMatwhich allows to decompose the homography matrix to a set of rotations, translations and plane … Meer weergeven

Web30 sep. 2024 · However, correspondence outliers and insufficient feature coverage will lead to unreliable local homography fitting. In this paper, we propose a novel method of multi-homography estimation and inference, driven by contour alignment. Our method uses explicit structural verification through contour alignment to eliminate incorrectly fitted ...

So can account e.g. for a back tilted plane. If your object is planar but can do out-of-plane rotations, the you need a homography to model that. If your mode is not planar, then the homography is not the true model.
