Safety-focused training is essential for the operation and maintenance concentrated on reliability of critical infrastructures, such as power grids. This paper introduces evaluates a system substation operational by exploring interacting with realistic models in virtual worlds using serious games. The reality (VR) simulator used building information modelling (BIM) from 115 kV to develop scenario high technical detail suitable professional training. created interactive that could be explored...
Graphical Abstract
This article presents a real time Unmanned Aerial Vehicles UAVs 3D pose estimation method using planar object tracking, in order to be used on the control system of UAV. The explodes rich information obtained by projective transformation objects calibrated camera. algorithm obtains metric and components reference (landmark or helipad) with respect UAV camera coordinate system, robust tracking based homographies. is validated flights that compare estimated data against inertial measurement...
This work presents our initial approach to remote sensing and precision agriculture for monitoring crop fields in Colombia. Using an autonomous quadcopter UAV (unmanned aerial vehicle) equipped with a multispectral camera onboard, goal is provide farmers integrated tool measuring assessing live green vegetation by assembling terrain image mosaic based on capturing images of the terrain. paper how integrate UAV-based solution geo-tagged imagery methods compute mosaics. A field report shows...
A new method for power line detection based on computer graphics algorithms is presented. The algorithm uses geometric relationships that are inherent to the circle symmetry. detects segments linked in a posterior stage. For detection, we use Canny and Steerable Filters. We developed two tests validating proposed approach. first one synthetic images second real taken from UAVs. results show this not only efficient but it also takes compared with state of art short computing time without GPU
This paper describes the development of an aerial system applied for terrain mapping and geo-detection explosive landmine-like objects. In practice in Colombia, a large percentage anti-personnel mines that still remain across country are hand-crafted partially exposed on terrain's surface so they can be triggered. scenario facilitates use vision-based approach detection these artifacts. Our goal is to integrate computer vision algorithms within low-cost UAV robot suited Colombian scenario....
Leaf nitrogen (N) directly correlates to chlorophyll production, affecting crop growth and yield. Farmers use soil plant analysis development (SPAD) devices calculate the amount of present in plants. However, monitoring large-scale crops using SPAD is prohibitively time-consuming demanding. This paper presents an unmanned aerial vehicle (UAV) solution for estimating leaf N content rice crops, from multispectral imagery. Our contribution twofold: (i) a novel trajectory control strategy reduce...
Robotic-assisted systems have gained significant traction in post-stroke therapies to support rehabilitation, since these can provide high-intensity and high-frequency treatment while allowing accurate motion-control over the patient’s progress. In this paper, we tackle how active through a robotic-assisted exoskeleton by developing novel closed-loop architecture that continually measures electromyographic signals (EMG), order adjust assistance given exoskeleton. We used EMG acquired from...
This paper explores the possibilities to use robust object tracking algorithms based on visual model features as generator of references for UAV control. A scale invariant feature transform (SIFT) algorithm is used detecting salient points at every processed image, then a projective transformation evaluating obtained using version RANSAC algorithm, in which series matched key-points pairs that fulfill equations are selected, rejecting otherwise corrupted data. The system has been tested...
In this paper we introduce a real-time trinocular system to control rotary wing Unmanned Aerial Vehicles based on the 3D information extracted by cameras located ground. The algorithm is key features onboard UAV estimate vehicle's position and orientation. validated against sensors known positions, showing that proposed camera configuration robustly estimates helicopter's with an adequate resolution, improving estimation, especially height estimation. obtained results show suitable...
UAVs (unmanned aerial vehicles) are becoming more popular for civil task due to their unique flight capabilities. The video shows several capabilities of a platform used as main research testbed computer vision unmanned vehicles. Four major areas explored in the present work visual servoing, trajectory planning, power line inspection and stereo-based navigation.
This paper presents a Fuzzy Control application for landing task of an Unmanned Aerial Vehicle, using the 3D-position estimation based on visual tracking piecewise planar objects. allows UAV to land scenarios in which it is only possible use information obtain position vehicle. The homography permits realtime UAV's pose with respect helipad monocular camera. Logic definition model-free control system UAV. controller analyzes generate altitude commands develop task.
