Multi-Camera Array with Adjacent Fields of View

摘要

Multiple cameras are arranged in an array at a pitch, roll, and yaw that allow the cameras to have adjacent fields of view such that each camera is pointed inward relative to the array. The read window of an image sensor of each camera in a multi-camera array can be adjusted to minimize the overlap between adjacent fields of view, to maximize the correlation within the overlapping portions of the fields of view, and to correct for manufacturing and assembly tolerances. Images from cameras in a multi-camera array with adjacent fields of view can be manipulated using low-power warping and cropping techniques, and can be taped together to form a final image.

主权项

1. An apparatus comprising:
a 2×2 camera array including four cameras, each camera including a plurality of lenses, an image sensor, and a housing securing the plurality of lenses and image sensor such that light passing through an aperture of the housing is directed by the plurality of lenses to be incident upon the image sensor; wherein each camera in the plurality of cameras is oriented at a pitch greater than 60 degrees and less than 80 degrees, roll greater than 30 degrees and less than 50 degrees, and yaw greater than 60 degrees and less than 80 degrees such that an image captured by a first camera in the plurality of cameras comprises an overlapping portion with at least one other camera in the plurality of cameras when images are synchronously captured by the plurality of cameras, and such that each camera in the plurality of cameras faces in a direction that converges in at least one dimension with a direction faced by at least one other camera in the plurality of cameras.
