Real-Time Compact Environment Representation for UAV Navigation

Perception for UAV: Vision-Based Navigation and Environment Modeling

Nowadays, cameras and other exteroceptive sensors are on board of a large variety of automatic platforms, such as Unmanned Aerial Vehicles (UAV), space exploration probes and missiles. However, apart from this latter application, they are mostly used as payload and not to pilot the vehicle itself. In this paper, we focus on the use of computer vision for UAV perception to navigate through the e...

Real-Time Navigation, Guidance, and Control of a UAV Using Low-Cost Sensors

Applying low-cost sensors for the Guidance, Navigation and Control (GNC) of an autonomous Uninhibited Aerial Vehicle (UAV) is an extremely challenging area. This paper presents the real-time results of applying a low-cost Inertial Measurement Unit (IMU) and Global Positioning System (GPS) receiver for the GNC. The INS/GPS navigation loop provides continuous and reliable navigation solutions to ...

Real Time Navigation Approach for Mobile Robot

Real time navigation is still challenge in mobile robotics. The challenge interacts with decision and optimization of obstacle avoidance and path distance respectively, when robot moves from initial position to target position in complex crowded environment. This paper develops the efficient navigational controller by using modified Firefly Algorithm (FA) which is studied over Normal Probabilit...

Specialized Hardware for Real-Time Navigation

I n this paper we propose a specialized hardware architecture for the real time visual navigation of a mobile robot. The adopted navigation method is based on a two-steps approach. Features are extracted and matched over an image sequence which is captured by a videocamera (mounted on a mobile robot) during its motion. As a result, a 2D motion field is recovered and used to extract ego-motion p...
