A Laser Obstacle Warning and Avoidance system for Manned and Unmanned Aircraft

Abstract: In this paper we briefly review the research and flight test activities performed to develop and integrate the Laser Obstacle Avoidance and Monitoring (LOAM) system on helicopter platforms and focus on the recent research advances towards the development of a new scaled LOAM variant for small-to-medium size Unmanned Aircraft (UA) platforms. After a brief description of the system architecture and sensor characteristics, emphasis is given to the performance models and data processing algorithms developed for ob… Show more

“…Research groups on robotics have proposed different techniques for obstacle avoidance, based on sensors like LiDAR [4][5][6] and RGB-D [7,8], which show robustness to identifying obstacles; but implementing these devices in a compact MAV is difficult, expensive, and also, these consume additional electrical power. When we work with UAVs and want to implement other device onboard, we need to consider the payload that they can carry, limiting the use of any UAV.…”

“…In all cases, the agents are assumed to be small/mini unmanned systems [20], [21]; expected to operate in close proximity (≤ 500m) to one another. The experimental conditions used in the following studies are presented in Table II.…”

“…All UAVs are assumed to have a maximum characteristic size of r = 2.5m; the average size of a mini class UAV [21] and move at a typical cruise speed of 18m/s ≈ 40mph. The simulation time step is defined as 4Hz; the repetition frequency of existing Laser Obstacle Avoidance Marconi (LOAM) sensor devices [20].…”
