Claim:
1. A computer-implemented method of rectifying a stereoscopic pair of cameras for stereoscopic image capture, comprising: capturing, using the stereoscopic pair of cameras including a first camera and a second camera, a first image using the first camera and a second image using the second camera; analyzing, using at least one processor of a computing device, the first image and the second image to determine a presence of one or more objects and an amount of disparity for at least a portion of the one or more objects; determining, based at least in part on an environmental condition, a first suitability of a stereo image based segmenting technique; determining, based at least in part on the environmental condition, a second suitability of an infrared (IR) based segmenting technique; identifying a selected segmenting technique from the stereo image based segmenting technique and the IR based segmenting technique, based on the first suitability and the second suitability; segmenting, using the selected segmenting technique, the first image and the second image into at least a foreground portion and a background portion, the foreground portion including a foreground object and the background portion including a background object, the foreground object and the background object determined to be separated by at least a threshold distance as based at least in part on the amount of disparity; locating, for each of the first image and the second image, one or more feature points for each of the foreground object and the background object, each feature point of the one or more feature points represents a distinctive point that identifies a corresponding object; determining a mapping of the feature points of the foreground object and the feature points of the background object in the first image to corresponding feature points in the foreground object and feature points in the background object in the second image; generating a rectifying model based at least in part upon the mapping; and applying the rectifying model to one or more subsequent images captured by at least one of the first camera or the second camera to reduce misalignment in the one or more subsequent images, data in the one or more subsequent images capable of being used to generate one or more stereoscopic images.
