Stereo imaging using disparate imaging devices

摘要

Stereo imaging can be provided on an electronic device without the need for two matched, high resolution, large format cameras. In various embodiments, two or more cameras of disparate types can be used to capture stereoscopic images. Various processing algorithms can be used to adjust aspects such as the effective pixel size and depth of focus in order to provide for sufficient information to generate three-dimensional images without significant artifacts resulting from differences in the mismatched cameras.

主权项

1. A method of producing a stereoscopic image, comprising:
capturing a first image using a first camera having a first field of view and capturing a second image using a second camera having a second field of view, the second field of view at least partially overlapping the first field of view; capturing a third image using a third camera positioned on the electronic device to have a third field of view at least partially overlapping the first field of view and the second field of view, the third camera having at least one different imaging characteristic than each of the first camera and the second camera; generating, using at least one processor of the electronic device, a depth map including a depth value for each pixel location of the depth map using differences in a position of at least one object between the first image and the second image based at least in part on disparity information determined using at least one of edge matching, color matching, or texture matching of information in the first image and the second image; locating pixels in the third image that correspond to pixel locations of the depth map; and using, using the at least one processor of the electronic device, color information for each located pixel in the third image to determine a color value for a corresponding pixel location of the depth map, wherein a stereoscopic image is able to be created using depth information from the first and second cameras and color information from the third camera.
