MATRICE 30 SERIES User Manual
The infrared sensing systems may NOT detect the distance accurately in the following situations:
a. Flying over surfaces that can absorb sound waves (e.g., asphalt road surfaces).
b. A large area of strong reectors situated at a distance of more than 15 m (e.g., multiple trac signs
placed side by side).
c. Small obstacles (e.g., iron wires, cables, tree branches, or leaves).
d. Mirrors or transparent objects (e.g., water or glass).
e. In low-visibility environments (e.g., heavy fog or snow).
Keep the vision sensors clean at all times. Any dirt or stain may aect their function.
The vision system relies on surface patterns or texture to process image data and obtain
position information. Make sure the surrounding environment has sucient lighting and clearly
textured ground.
The vision system cannot function properly in dark environments and over surfaces without
clear patterns or texture such as water and ice.
The aircraft cannnot avoid moving obstacles such as people, animals, or vehicles.
