First Claim
1. An unmanned aerial vehicle comprising:
- a frame;
a primary imaging device joined to the frame, wherein the primary imaging device comprises a primary lens module;
a secondary imaging device joined to an external surface of the primary lens module, wherein the secondary imaging device comprises a secondary lens module; and
a control unit having at least one computer processor configured to at least;
cause a plurality of primary images to be captured by the primary imaging device;
cause a plurality of secondary images to be captured by the secondary imaging device;
define at least one vector representative of motion of the secondary imaging device based at least in part on the plurality of secondary images; and
stabilize at least one of the plurality of primary images based at least in part on the at least one vector representative of the motion of the secondary imaging device.

Abstract
An aerial vehicle may include a first sensor, such as a digital camera, having a lens or other component that includes a second sensor mounted thereto. Information or data, such as digital images, captured using the second sensor may be used to determine or predict motion of the lens, which may include components of translational and/or rotational motion. Once the motion of the lens has been determined or predicted, such motion may be used to stabilize information or data, such as digital images, captured using the first sensor, according to optical or digital stabilization techniques. Where operations of the first sensor and the second sensor are synchronized, motion of the second sensor may be modeled based on information or data captured thereby, and imputed to the first sensor.

5. A method comprising:
-
capturing, by a first sensor, first data during an operation of the aerial vehicle, wherein the first sensor is mounted to the aerial vehicle; capturing, by a second sensor, second data during the operation of the aerial vehicle, wherein the second sensor is mounted to at least a portion of the first sensor; determining, by at least one computer processor, at least one vector representative of motion of the first sensor based at least in part on the second data; and modifying, by the at least one computer processor, the first data based at least in part on the at least one vector; and storing the modified first data in at least one data store. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
