Can lunar rovers navigate using just one image every four seconds?

Lunar rovers face extreme power and compute constraints, making frequent camera updates infeasible. BEVIO uses bird's-eye-view image matching to enable reliable visual-inertial odometry with ultra-sparse updates (one frame every 4 seconds), robust across day-night transitions and severe lighting changes. Field tests on a half-scale rover in California demonstrated continuous day-night traverses, suggesting real applicability for upcoming lunar missions.
