Feature choice for real-time mobile SLAM
WHAT IT TESTS: system-level feature trade-offs. OUTLINE: pick ORB for fast FAST keypoints and cheap binary descriptors matched by Hamming distance; accept reduced robustness versus SIFT for real-time, low-power operation.
WHAT IT TESTS: whether you can justify a feature pipeline under hard real-time and power constraints. ANSWER OUTLINE: real-time SLAM must detect, describe, and match features every frame within a tight budget, so ORB is the standard choice: FAST keypoints, oriented BRIEF binary descriptors, Hamming-distance matching, and patent-free. It trades some robustness to large scale and viewpoint change versus SIFT, but multi-scale pyramids and tracking continuity compensate. RED FLAG: insisting on SIFT without addressing the latency and battery cost.
