Inspection of a simulated Endurance spacecraft (axis-symmetric inertia symmetry, from Interstellar) using a simulated inspector spacecraft and the algorithms in [1]. Endurance model credit to [2]. Sped up 2.5X.
Legend:
(Top Left) Left stereo image with features shown in blue, frame-to-frame SURF feature matches shown in green (red when less than 6 matches). Loop closures shown in yellow.
(Top Right) Depth map (grey) with centroid (green), and feature search window (blue).
(Bottom Left) Map from current iSAM2 pose graph solution, with first inliers (purple), current inliers (green), geometric frame triad (red, green, blue), and inliers in order of detection (blue, green, orange, yellow). All features shown as small grey dots.
(Bottom Right) Visually-measured (purple) and gyroscope-measured (cyan) body angular velocities, with estimated intermediate frame triad (thin dashed) and estimated body frame triad (thick dashed). Fit conic projections (black), and true (o) and estimated (•) inertia ratios (bottom).
