Abstract

Images captured by multi-camera arrays with overlap regions can be stitched together using image stitching operations. An image stitching operation can be selected for use in stitching images based on a number of factors. An image stitching operation can be selected based on a view window location of a user viewing the images to be stitched together. An image stitching operation can also be selected based on a type, priority, or depth of image features located within an overlap region. Finally, an image stitching operation can be selected based on a likelihood that a particular image stitching operation will produce visible artifacts. Once a stitching operation is selected, the images corresponding to the overlap region can be stitched using the stitching operation, and the stitched image can be stored for subsequent access.

Description

BACKGROUND[0001]Technical Field[0002]This disclosure relates to camera arrays and, more specifically, to methods for stitching images captured by a camera array.[0003]Description of the Related Art[0004]Corresponding images captured by multiple cameras in a multi-camera array can be combined (or “stitched”) together to create larger images. The resulting stitched images can include a larger field of view and more image data than each individual image. Generating stitched images using a multi-camera array can be more cost-effective than capturing an image of a similar field of view and image data using a higher-resolution and / or higher-performance camera. However, the process of stitching images can produce stitched images with stitching artifacts at or near the stitch lines.BRIEF DESCRIPTIONS OF THE DRAWINGS[0005]The disclosed embodiments have other advantages and features which will be more readily apparent from the following detailed description of the invention and the appended c...
