Systems and Methods for Synthesizing High Resolution Images Using Images Captured by an Array of Independently Controllable Imagers

摘要

Systems and methods in accordance with embodiments of the invention are disclosed that use super-resolution (SR) processes to use information from a plurality of low resolution (LR) images captured by an array camera to produce a synthesized higher resolution image. One embodiment includes obtaining input images using the plurality of imagers, using a microprocessor to determine an initial estimate of at least a portion of a high resolution image using a plurality of pixels from the input images, and using a microprocessor to determine a high resolution image that when mapped through the forward imaging transformation matches the input images to within at least one predetermined criterion using the initial estimate of at least a portion of the high resolution image. In addition, each forward imaging transformation corresponds to the manner in which each imager in the imaging array generate the input images, and the high resolution image synthesized by the microprocessor has a resolution that is greater than any of the input images.

1. An array camera, comprising:
an imager array including a plurality of imagers and control circuitry for independently triggering each imager, where:
each of the imagers receives light through a separate lens system and includes a sensor;the control circuitry controls the imaging parameters of the sensor of each imager; a processor; and memory containing an image processing pipeline software application and parameters defining a forward imaging transformation for the imager array; wherein the image processing pipeline software directs the processor to:
trigger the imagers in the imager array to obtain a plurality of input images and store the input images in memory;determine an initial estimate of at least a portion of a high resolution image from a plurality of pixels from the input images; anddetermine a high resolution image that when mapped through the forward imaging transformation matches the input images to within at least one predetermined criterion using the initial estimate of at least a portion of the high resolution image.
