4.2 Obstacle detection and collision avoidance technology
Drones are equipped with collision avoidance systems for safety purposes [9].
These systems consist of sensors that do not scan the environment but detect obsta-
cles. Data from the vision sensor,
ultrasonic, infrared, LiDAR, time-of-flight (ToF),
and monocular vision sensors transform images into 3D maps, allowing the flight
controller to detect and avoid the object. With the help of software algorithms and
SLAM
technology using this data, 6-way obstacles are detected, and necessary actions
are taken to prevent them.
