Abstract: Disclosed herein are devices and methods for generating stereoscopic views of the eye (or any desired anatomic structure) using a dual-camera portable computing device. The locations of the two cameras are fixed, and the camera lenses may have different focal lengths. For example, the focal length of the second camera lens may be longer than the focal length of the first camera lens. One variation of a detachable imaging system comprises an objective lens and a relay lens that are disposed over the two cameras. The relay lens may be disposed over the first and second cameras, and have a focal length that is greater than the focal length of the first camera lens and less than or equal to the focal length of the second camera lens.

Abstract: Methods and systems describe remotely triggering the capture of media data. A navigator device at a server is connected with an operator device over a network, with the operator device being handled by an operator. Streaming media data is received at the server, and concurrently, the incoming streaming media data is analyzed to determine whether a match for one or more predefined visual landmarks can be identified. Upon a determination that a match cannot be identified, instructions are communicated, via the navigator device, for the operator to reposition the operator device. Upon a determination that a match for one or more predefined visual landmarks can be identified, capture of the streaming media data with the visual landmarks is triggered.
