Dense field imaging
First Claim
1. An imaging system configured to capture digital images, comprising:
- a first imaging block configured to obtain and output a first image data set representative of a first portion of a light field, wherein the first image data set represents the first portion of the light field as a function comprising at least four dimensions as inputs to represent luminance or radiance as a function of space and direction;
a second imaging block physically separate from the first imaging block and configured to obtain and output a second image data set representative of a second portion of the light field, wherein the second image data set represents the second portion of the light field as a function comprising at least four dimensions as inputs to represent luminance or radiance as a function of space and direction;
one or more processors operably coupled to the first and second imaging blocks;
one or more memory devices operably coupled to the one or more processors, the one or more processors and one or more memory devices configured to;
combine at least the first image data set and the second image data set to derive a third image data set based on at least a spatial relationship between the first and second portions of the light field; and
store the third image data set in the one or more memory devices.

Abstract
Dense field imagers are disclosed which are configured to provide combined, aggregated, fused, and/or stitched light field data for a scene. A dense field imager can include a plurality of imaging elements configured to be joined into image blocks or facets that each provides light field data about a scene. The dense field imager can include a plurality of facets in a fixed or modular fashion such that the dense field imager is configured to combine, aggregate, fuse and/or stitch light field data from the plurality of facets. The facets can be mounted such that one or more facets are non-coplanar with other facets. The facets can be configured to provide a representation of the light field with overlapping fields of view. Accordingly, the dense field imager can provide dense field data over a field of view covered by the plurality of facets.

8. A method of compiling an image data set, comprising:
-
obtaining a first image data set representative of a first portion of a light field with a first imaging block, wherein the first image data set represents the first portion of the light field as a function comprising at least four dimensions as inputs to represent luminance or radiance as a function of space and direction; obtaining a second image data set representative of a second portion of the light field with a second imaging block that is physically separate from the first image block, wherein the second image data set represents the second portion of the light field as a function comprising at least four dimensions as inputs to represent luminance or radiance as a function of space and direction; with one or more processors, combining at least the first image data set and the second image data set to derive a third image data set that is based on at least a spatial relationship between the first and second portions of the light field; and storing the third image data set in one or more memory devices. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
