Abstract

 

Drones are growing in popularity for their wide-ranging potential applications. The global drone market is expected to reach 5.5 billion dollar by 2020. While drones are popular and applied to a variety of areas, they have some rooms for improvement. Since drones are flown by operators and their batteries are also replaced or charged manually, it is a laborious and troublesome work to operate drones by hand for a long time. Additionally, we need to resolve some safety issues arising from communication interruption between an operator and a drone, and obstacle collision. In this regard, now is the time when an autonomous drone control system should be developed. In order to develop the autonomous drone control system, it is most important to achieve precise localization through 3 D perception technology. In this talk, we discuss how to construct high precision 3D maps for indoor and outdoor uses through LiDAR, composite sensors, and omnidirectional cameras. Indoor and outdoor localization systems based on composite 3D maps will be introduced together with real-time algorithms for aligning positions and directions among sensors, and estimating and compensating errors within sensors, with high precision GPS/INS integration technologies.
