AUGMENTED VIDEO SYSTEM PROVIDING ENHANCED SITUATIONAL AWARENESS
First Claim
1. A method for providing enhanced situational awareness to image data captured by an image capturing device carried by an unmanned aircraft vehicle system, the method comprising:
- storing, for at least one of a plurality of objects of interest, position data for the at least one object of interest;
storing, for at least one of a plurality of geographic areas, topographical data for the at least one geographic area;
receiving image data captured by the image capturing device carried by the unmanned aircraft vehicle, wherein at least one of a plurality of frames of the received image data has associated metadata comprising a timestamp, an orientation of the unmanned aircraft vehicle, an orientation of the image capturing device relative to the unmanned aircraft vehicle, configuration information for the image capturing device, a position for the unmanned aircraft vehicle, and a velocity for the unmanned aircraft vehicle; and
for at least one of a plurality of frames of the received image data,determining a transformation matrix based on metadata associated with the frame, andfor each of at least one overlay,applying the determined transformation matrix data to the overlay to transform the overlay, andproviding the transformed overlay for display in association with a display of the frame.

Abstract
A facility, comprising systems and methods, for providing enhanced situational awareness to captured image data is disclosed. The disclosed techniques are used in conjunction with image data, such as a real-time or near real-time image stream captured by a camera attached to an unmanned system, previously captured image data, rendered image data, etc. The facility enhances situational awareness by projecting overlays onto captured video data or “wrapping” captured image data with previously-captured and/or “synthetic world” information, such as satellite images, computer-generated images, wire models, textured surfaces, and so on. The facility also provides enhanced zoom techniques that allow a user to quickly zoom in on an object or area of interest using a combined optical and digital zoom technique. Additionally, the facility provides a digital lead indicator designed to reduce operator-induced oscillations in commanding an image capturing device.
