Infrared sensors are essential for reducing and eliminating safety risks when flying with a LiDAR UAV. An infrared obstacle avoidance sensor is composed of an infrared transmitter, an infrared receiver, and a potentiometer. These components are necessary for testing the component and subsystem of the UAV, as well as the UAV as a whole. In order to ensure safety requirements, sensors and measurements play a critical role in proposed solutions to increase the safety of unmanned aerial vehicles.
This includes testing new construction materials, accurately assessing performance, monitoring the condition of the vehicle, and quantifying injuries and collision damage from unmanned aerial vehicles. To reduce computing power and response times, detection and avoidance methods simplify the collision prevention process to detect and avoid individual obstacles. This helps to avoid collisions between unmanned aerial vehicles within a swarm, as well as between unmanned aerial vehicles and obstacles. A low-altitude obstacle detection framework for small unmanned aerial vehicles is based on the fusion of LiDAR and visible light camera data.
Geometric approaches analyze geometric attributes to simulate the trajectories of the UAV and obstacles, ensuring that the minimum allowable distance between UAVs and obstacles is not exceeded. Raw LiDAR data includes distance, azimuth, and elevation angle in the LiDAR polar coordinate system. Once an obstacle is perceived and detected, it can be avoided by following different approaches. The joint calibration of LiDAR and camera obtains three-dimensional coordinates of corner points in point clouds and coordinates of pixels in an image.
This allows for the adjustment of the coordinate conversion matrix between the LiDAR coordinate system and pixel coordinate system of the image. A non-repetitive three-dimensional scanning LiDAR is selected whose six lasers scan at the same time without repeating scan paths. This avoids deficiencies of traditional LiDAR with mechanical rotating structures in the vertical direction. In order to maximize safety when flying with a LiDAR UAV, it is important to use sensors integrated into the UAV as well as develop test procedures for evaluating performance of UAVs.
These sensors are essential for detecting obstacles in order to avoid collisions between unmanned aerial vehicles within a swarm, as well as between unmanned aerial vehicles and obstacles. The use of infrared sensors is key for obstacle detection when flying with a LiDAR UAV. These sensors are composed of an infrared transmitter, an infrared receiver, and a potentiometer which are necessary for reducing and eliminating safety risks during flight. Additionally, they are essential for testing the component and subsystem of the UAV, as well as the UAV as a whole.
In conclusion, solutions for increasing safety when flying with a LiDAR UAV involve development and use of sensors integrated in the UAV, as well as development of test procedures for evaluating performance of UAVs. The use of infrared sensors is key for obstacle detection when flying with a LiDAR UAV in order to reduce computing power and response times while avoiding collisions between unmanned aerial vehicles within a swarm or between unmanned aerial vehicles and obstacles.
