Systems and methods for stereo imaging with camera arrays
First Claim
1. A method of generating depth information for an object in a scene using two or more array cameras that each include a plurality of imagers where each imager captures an image of the scene, the method comprising:
- obtaining a first set of image data comprising image data of a scene captured from a first set of different viewpoints;
identifying an object of interest in the first set of image data;
determining a first depth measurement for the object of interest using at least a portion of the first set of image data;
determining whether the first depth measurement for the object of interest is above a predetermined threshold; and
when the depth for the object of interest is above the predetermined threshold;
obtaining a second set of image data comprising image data of the same scene from a second set of different viewpoints located known distances from at least one viewpoint in the first set of different viewpoints;
identifying the object of interest in the second set of image data; and
determining a second depth measurement for the object of interest using at least a portion of the first set of image data and at least a portion of the second set of image data.

Abstract
Systems and methods for stereo imaging with camera arrays in accordance with embodiments of the invention are disclosed. In one embodiment, a method of generating depth information for an object using two or more array cameras that each include a plurality of imagers includes obtaining a first set of image data captured from a first set of viewpoints, identifying an object in the first set of image data, determining a first depth measurement, determining whether the first depth measurement is above a threshold, and when the depth is above the threshold: obtaining a second set of image data of the same scene from a second set of viewpoints located known distances from one viewpoint in the first set of viewpoints, identifying the object in the second set of image data, and determining a second depth measurement using the first set of image data and the second set of image data.
