System and methods for calibration of an array camera
First Claim
1. A method for manufacturing an array camera device, the method comprising:
- assembling an array of cameras comprising a plurality of imaging components that capture images of a scene from different viewpoints, where the plurality of imaging components comprises;
a set of one or more reference imaging components, each having a reference viewpoint; and
a set of one or more associate imaging components;
configuring the array of cameras to communicate with at least one processor;
configuring the processor to communicate with at least one display;
configuring the processor to communicate with at least one type of memory; and
performing a calibration process for the array of cameras, where the calibration process comprises;
capturing images of a test pattern using the array of cameras, where each of the plurality of imaging components captures an image from a particular viewpoint;
generating scene independent geometric corrections for reference image data captured by a reference imaging component using test pattern image data captured by the reference imaging component and data describing the test pattern using the processor;
generating a corrected test pattern image for the reference imaging component based on the scene independent geometric corrections for the reference image data and the image of the test pattern captured by the reference imaging component using the processor; and
generating scene independent geometric corrections for associate image data captured by an associate imaging component using test pattern image data captured by the associate imaging component and data for the corrected test pattern image using the processor; and
loading calibration information into the memory.

Abstract
Systems and methods for calibrating an array camera are disclosed. Systems and methods for calibrating an array camera in accordance with embodiments of this invention include the capturing of an image of a test pattern with the array camera such that each imaging component in the array camera captures an image of the test pattern. The image of the test pattern captured by a reference imaging component is then used to derive calibration information for the reference component. A corrected image of the test pattern for the reference component is then generated from the calibration information and the image of the test pattern captured by the reference imaging component. The corrected image is then used with the images captured by each of the associate imaging components associated with the reference component to generate calibration information for the associate imaging components.
