Homography in computer vision
In the field of computer vision, any two images of the same planar surface in space are related by a homography (assuming a pinhole camera model). This has many practical applications, such as image rectification, image registration, or camera motion—rotation and translation—between two images. … Meer weergeven We have two cameras a and b, looking at points $${\displaystyle P_{i}}$$ in a plane. Passing from the projection where $${\displaystyle {}^{a}z_{i}}$$ and Meer weergeven When the image region in which the homography is computed is small or the image has been acquired with a large focal length, … Meer weergeven • homest is a GPL C/C++ library for robust, non-linear (based on the Levenberg–Marquardt algorithm) homography … Meer weergeven • Direct linear transformation • Epipolar geometry • Feature (computer vision) • Fundamental matrix (computer vision) Meer weergeven • Serge Belongie & David Kriegman (2007) Explanation of Homography Estimation from Department of Computer Science and … Meer weergeven Web2.1.
