Abstract: A system and method of generating an enhanced Lund and Browder chart and total body surface area burn score is described herein. In some embodiments, a plurality of images is obtained from of a patient using a camera system. The images may be taken by aligning the patient's body with pose templates presented on a display of the camera system.

Abstract: Systems and techniques for navigation in a GPS-denied environment that do not rely on locations of known points. Instead, the operator can measure distance and/or inclination as well as azimuth to arbitrary points on the visual horizon (or sub-horizon) from their location. These observations can then be compared to precomputed distances and inclinations for corresponding azimuths to the visual horizon of a grid of points based on known surface terrain data. The closest grid point to the observer's location obtained in this way can be refined using a model of the surrounding environment, allowing for the operators position to be quickly and accurately determined.
