Method and apparatus for correction of perspective distortion
First Claim
Patent Images
1. A method of correcting perspective distortion in an imaged scene, the method comprising:
- identifying a plurality of points in the imaged scene, wherein the plurality of points define a shape;
determining two vanishing points based on the plurality of points;
determining a first set of reference points within the shape defined by the plurality of points;
transforming the first set of reference points into a second set of reference points;
adjusting an aspect ratio associated with the first set of reference points;
transforming the imaged scene to reduce perspective distortion in the imaged scene;
rotating a displayed image associated with the first set of reference points if lines from a center point of a shape defined by the first set of reference points to the two vanishing points do not pass through adjacent sides of the shape defined by the first set of reference points.

Abstract
Perspective distortion in an imaged scene is corrected by identifying a group of points in the imaged scene such that the group of points define a shape. Two vanishing points are determined based on the group of points in the imaged scene. The process determines a first set of reference points within the shape defined by the group of points and transforms the first set of reference points into a second set of reference points. An aspect ratio associated with the first set of reference points is adjusted and the imaged scene is transformed to reduce perspective distortion in the imaged scene.
