MATRICE 30 SERIES User Manual

Obstacle Sensing

Obstacle sensing works best when the lighting is adequate and the obstacle is clearly textured. It does

not work well with obstacles that are less dense such as twigs on a tree. The aircraft must y at a

speed below 17 m/s with a maximum tilt angel of 25° to ensure a sucient braking distance. Aircraft

cannot detect and avoid obstacles that are out of the detection range.

50°

Infrared Sensing System

The infrared sensing system can only be used to sense large or highly reective obstacles and rough

surfaces. Aircraft cannot sense obstacles that are out of the detection range. The downward infrared

sensing system is used for positioning and assisting with altitude calculations during takeo and landing,

while the infrared sensing system on the other ve sides is for obstacle sensing.

Warnings

The measurement accuracy of the vision system is easily aected by the light intensity and the surface

texture of the object. The infrared sensing system can only be used to sense large or highly reective

obstacles and rough surfaces. The vision system may NOT function properly in the following situations:

a. Flying over monochrome surfaces (e.g., pure black, white, red, or green) or those without clear

texture.

b. Flying over surfaces with strong reected light or images.

c. Flying over water, ice, or transparent surfaces.

d. Flying over moving surfaces or objects (e.g., moving crowds, or swaying reeds, shrubs, or grass).

e. Flying in an area where lighting changes frequently or drastically or with direct exposure to strong

light.

f. Flying over extremely dark (< 15 lux) or extremely bright (> 10,000 lux) surfaces.

g. Flying at high speeds below 2 m above the ground (e.g., faster than 14 m/s at a 2m height or 5 m/s

at a 1m height).

h. Small obstacles (e.g., iron wires, cables, tree branches, or leaves).

i. The lens is dirty (e.g., from raindrops or ngerprints).

j. In low-visibility environments (e.g., heavy fog or snow).
