An imaging device can be mounted on a vehicle and used to capture images. The imaging device can include a camera assembly rotatable relative to a platform of the vehicle and about two or three camera axes. The camera assembly can include a camera and a mirror attached to the camera. The mirror can be rotatable relative to the camera and about one or two mirror axes, different from the camera axes. Users can provide input to controllers that operate the vehicle, the camera, and the mirror to control both flight and the line-of-sight of the camera. The controllers combine separate inputs as well as measured conditions, such as inertial angles, to coordinate control of vehicle, camera, and mirror parameters, such as yaw adjustments to both the camera and the mirror to achieve a desired line-of-sight.

1. An aircraft comprising: a platform;a camera assembly rotatable relative to the platform and about three camera axes, the camera assembly comprising: a camera; anda mirror attached to the camera, wherein the mirror is rotatable relative to the camera and about a mirror axis, different from the three camera axes;a first inertial measurement unit configured to measure inertial angles of the camera assembly; anda second inertial measurement unit configured to measure inertial angles of the mirror. 2. The aircraft of claim 1, further comprising a gimbal assembly for rotating the camera assembly about the three camera axes. 3. The aircraft of claim 1, further comprising a mirror gimbal for rotating the mirror about the mirror axis. 4. The aircraft of claim 1, wherein the camera is oriented to capture an image reflected by the mirror. 5. The aircraft of claim 1, wherein the three camera axes intersect at a first location and the mirror axis does not intersect the first location. 6. The aircraft of claim 1, further comprising: a vehicle controller for receiving input signals from a user and sending command signals to devices for controlling propulsion and/or orientation of the aircraft;a camera controller for receiving input signals from a user and sending command signals to control rotation of the camera assembly; anda mirror controller for receiving input signals from a user and sending command signals to control rotation of the mirror. 7. An aircraft comprising: a platform; anda camera assembly rotatable relative to the platform and about three camera axes, the camera assembly comprising: a camera; anda mirror attached to the camera, wherein the mirror is rotatable relative to the camera and about a mirror axis, different from the three camera axes, wherein the three camera axes intersect at a center of mass of the camera assembly. 8. An aircraft comprising: a platform; anda camera assembly rotatable relative to the platform and about three camera axes, the camera assembly comprising: a camera; anda mirror attached to the camera, wherein the mirror is rotatable relative to the camera and about a mirror axis, different from the three camera axes, wherein the mirror axis intersects a center of mass of the mirror. 9. An imaging device comprising: a camera assembly rotatable relative to a platform and about three camera axes, the camera assembly comprising: a camera; anda mirror attached to the camera, wherein the mirror is rotatable relative to the camera and about a mirror axis, different from the camera axes, wherein the three camera axes intersect at a first location and the mirror axis does not intersect the first location. 10. The imaging device of claim 9, further comprising a gimbal assembly for rotating the camera assembly about the three camera axes. 11. The imaging device of claim 9, further comprising a mirror gimbal for rotating the mirror about the mirror axis. 12. The imaging device of claim 9, wherein the three camera axes intersect at a center of mass of the camera assembly. 13. The imaging device of claim 9, wherein the mirror axis intersects a center of mass of the mirror. 14. The imaging device of claim 9, wherein the three camera axes intersect at a first location and the mirror axis does not intersect the first location. 15. A method of operating a vehicle, the method comprising: receiving a command at the vehicle, the vehicle comprising a platform and a camera assembly, the camera assembly being rotatable relative to a platform of the vehicle and about three camera axes, the camera assembly comprising a camera and a mirror attached to the camera, wherein the command is to capture a view reflected by the mirror;in response to the command, rotating the mirror relative to the camera and about a mirror axis, different from the camera axes, to obtain the view;after rotating the mirror, rotating the vehicle and further rotating the mirror to maintain the view; andwith the camera, capturing an image of the view reflected by the mirror. 16. The method of claim 15, wherein rotating the mirror comprises rotating the mirror with a mirror gimbal. 17. The method of claim 15, further comprising rotating the camera assembly in response to the command. 18. The method of claim 15, further comprising rotating the camera assembly in response to the command, and wherein rotating the mirror is to compensate for errors while rotating the camera assembly. 19. The method of claim 15, wherein further rotating the mirror is to compensate for errors while rotating the vehicle. 20. The method of claim 15, wherein the three camera axes intersect at a first location and the mirror axis does not intersect the first location.
