Autonomous Flight of a Quadrotor Using Multi-Camera Visual SLAM
نویسندگان
چکیده
This paper presents the development and validation of a vision-based navigation and control system for a small unmanned quadrotor. The core of this system is a state estimator based on the so-called multi-camera parallel tracking and mapping algorithm, which provides accurate pose estimation for the quadrotor using multiple cameras. Built on cascaded proportional-integral-derivative control loops, a motion controller is designed to provide altitude, horizontal position, and yaw regulation. The performance of the proposed system is successfully demonstrated in fully autonomous flights in a variety of indoor and outdoor scenarios. Keywords— quadrotor, visual SLAM, PID control.

Visual-Inertial Navigation for a Camera-Equipped 25 g Nano-Quadrotor
We present a 25 g nano-quadrotor equipped with a micro PAL-camera and wireless video transmitter, with which we demonstrate autonomous hovering and figure flying using a visual-inertial SLAM system running on a ground-based laptop. To our knowledge this is the lightest quadrotor capable of visual-inertial navigation with off-board processing. Further we show autonomous flight with external pose...
متن کاملMonocular Vision Based Indoor Simultaneous Localisation and Mapping for Quadrotor Platform
An autonomous robot acting in an unknown dynamic environment requires a detailed understanding of its surroundings. This information is provided by mapping algorithms which are necessary to build a sensory representation of the environment and the vehicle states. This aids the robot to avoid collisions with complex obstacles and to localize in six degrees of freedom i.e. x, y, z, roll, pitch an...
متن کاملOff-board Visual Odometry and Control of an Ultralight Quadrotor MAV
In this paper, we propose an approach to autonomously control a quadrotor micro aerial vehicle (MAV). With take-off weight of 50 g and 8-min flight endurance, the MAV platform codenamed ‘KayLion’ developed by the National University of Singapore (NUS) is able to perform autonomous flight with pre-planned path tracking. The vision-based autonomous control is realized with a light weight camera s...
متن کاملAutonomous Approach and Landing for a Low-Cost Quadrotor Using Monocular Cameras
In this paper, we propose a monocular vision system for approach and landing using a low-cost micro aerial vehicle (MAV). The system enables an off-the-shelf Parrot AR.Drone 2.0 quadrotor MAV to autonomously detect a landpad, approach it, and land on it. Particularly, we exploit geometric properties of a circular landpad marker in order to estimate the exact flight distance between the quadroto...
متن کاملRobust Visual Simultaneous Localization and Mapping for MAV Using Smooth Variable Structure Filter
The work presented in this paper is a part of research work on autonomous navigation for Micro Aerial Vehicles (MAVs). Simultaneous Localization and Mapping (SLAM) is crucial for any task of MAV navigation. The limited payload of the MAV makes the single camera as best solution for SLAM problem. In this paper the Large Scale Dense SLAM (LSD-SLAM) pose is fused with inertial data using Smooth Va...
