Abstract

The disclosure provides a multi-stage image mapping mechanism for mapping a distorted image to a rectified image. For example, the multi-stage image mapping mechanism can remove homography from a distorted image to reconstruct a rectified image in two-stages: (1) a first stage in which distortion is partially removed from a distorted image to generate an intermediate image, and (2) a second stage in which residual distortion is removed from the intermediate image to recover the rectified image.

Description

technical field [0001] Disclosed herein are devices, systems, and methods related to homography projection of rectified images for image processing applications. Background technique [0002] Digital images can be formed by many devices and used for many practical purposes. The device includes a camera with an image sensor operating on visible or infrared light, such as a charge coupled device (CCD) image sensor or a complementary metal oxide semiconductor (CMOS) image sensor, a line scan sensor, a flying spot scanner, Electron microscopes, X-ray devices including computed tomography (CT) scanners, magnetic resonance imagers, and other devices known to those skilled in the art. There are practical applications in industrial automation, medical diagnostics, satellite imaging for a variety of military, civilian, and scientific purposes, photographic processing, surveillance and traffic surveillance, document processing, and many other applications. [0003] To serve these ap...
