Biological-Vision Inspired Dsa System for Uavs

Abstract

Uses of unmanned Aerial Vehicles (UAVs) have increased dramatically during the past several years, but currently still do not have convenient access to civil airspace because there is no onboard pilot, and it's impossible for UAVs to "see and avoid" other aircraft. So a Detect, Sense and Avoid system is needed to provide the UAV with instructions to steer the UAV clear of any potential collision with other traffic. An optical based DSA system is discussed in this paper to provide the UAV with "see and avoid" capability of at least equivalent to a piloted aircraft. DSA minimum detection range assessment, optical resolution requirement and image array size requirement are also discussed in this paper. Also an efficient natural vision system is presented in this paper for DSA system.
