KEYSTONE CORRECTIONS WITH QUADRILATERAL OBJECTS

An example method includes receiving by a processor of an image capturing device, an image of a quadrilateral object captured by a camera of the image capturing device. A homography matrix is calculated by the processor based on the image of the quadrilateral object and a known dimension of the quad...

More Information
Summary:An example method includes receiving by a processor of an image capturing device, an image of a quadrilateral object captured by a camera of the image capturing device. A homography matrix is calculated by the processor based on the image of the quadrilateral object and a known dimension of the quadrilateral object. The processor performs a keystone correction based on the homography matrix to convert a subsequent image captured by the camera into a corrected image.
