Claim Text:
1. A computer-implemented method, comprising: obtaining a first image including a first representation of a calibration object using a first camera, the calibration object including a first portion of alternating regions of a first intensity and one of a second intensity or a third intensity joined along a vertical axis at a specified angle with respect to a second portion of alternating regions of the first intensity and one of the second intensity or the third intensity, the first portion including one first region of the third intensity that intersects with one second region of the third intensity included in the second portion; obtaining a second image including a second representation of the calibration object using a second camera separated a distance from the first camera; locating a first reference point in the first image at which the first region and the second region intersect; locating a second reference point in the second image at which the first region and the second region intersect; locating first points, relative to the first reference point, in the first image corresponding to intersections of at least one of the first portion of alternating regions or the second portion of alternating regions; locating second points, relative to the second reference point, in the second image corresponding to the intersections; determining correlated points by correlating the first points to the second points using edges formed between at least one of the first portion of alternating regions or the second portion of alternating regions; determining a mapping of the correlated points to corresponding points of the calibration object; and storing the mapping for reducing at least one of misalignment or distortion effects from subsequent pairs of images captured by the first camera and the second camera, each subsequent pair of images capable of being used to generate a stereoscopic image.
