Fig. 4: Our quadrotor performs slope inspection in field environments.
From: Slope inspection under dense vegetation using LiDAR-based quadrotors
The text in the lower-right corner of the image corresponds to the experimental location in Table 1. a Quadrotor performing close-range inspection of flexible debris-resisting barriers (a1–a3) and stones caused by landslides (a4). b Quadrotor avoiding thin dropping vines. c Quadrotor maneuvering through dense tree canopies. d Quadrotor navigating through narrow tree branches.
