Graphical User Interface

In support the aforementioned research a user-friendly graphical user interface (GUI) was developed (Fig.U). This two-page GUI allows visualizing the real airdrop data, as well as analyzing emulated trajectories with the goal of assessing a visibility of enough geometry-based features (for pose estimation). Based on the DZ/KTM database the first page lets a user to choose any specific drop zone from the pop-up menu and the KTM constellation used in the specific drop (Fig.Ua). Then, the user navigates to the directory containing real-drop / emulated data. Next, he proceeds to the second page (Fig.Ub), where a 3D trajectory along with the simulated images from all (up to six) involved cameras is animated. The user can change the view point for the 3D trajectory (by moving azimuth and elevation sliders), “experiment” with a focal length of each camera, and “freeze” simulation at any instant of time.
