Fig. 6: Benchmark with DJI Mavic 3.
From: Slope inspection under dense vegetation using LiDAR-based quadrotors
a DJI Mavic 3 exhibiting conservative behavior in Normal Bypass mode. Similar behavior is observed in Brake mode within the same environment. Despite a clear feasible corridor in the commanded direction (a1), the DJI Mavic 3 fails to follow the pilot’s commands (a2–a4) and remains hovering in place (a5). b Comparison of obstacle avoidance between the DJI Mavic 3 and our quadrotor when encountering fine nets. DJI Mavic 3 collides with the fine nets (b1) under the right command (b2). However, our quadrotor maintains a safe distance from the fine nets (b4) under the forward command (b3). c Obstacle avoidance performance of DJI Mavic 3 in Nifty Bypass mode. In this mode, it is easy to collide with branches (c1). When the pilot controls DJI Mavic 3 to fly forward and downward (c2), it collides with the wire rope (c3) and crashes (c4). d First-person view pictures taken by our quadrotor when inspecting the 11SE-B/ND1 slope next to Lei Yue Mun Estate. e In Nifty Bypass mode, DJI Mavic 3, despite its ability to perceive dynamic objects, cannot avoid them, resulting in crashes.
