SIMD and OpenMP optimization of EKF-SLAM

2014 International Conference on Multimedia Computing and Systems (ICMCS), 2014
SLAM algorithms are widely used by autonomous robots operating in unknown environments. Several works have presented optimizations mainly focused on the algorithm complexity. New computing technologies (SIMD coprocessors, multicore architecture) can greatly accelerate the processing time but require rethinking the algorithm implementation.

Integrated Exploration Based SRT-EKF

2010 Ninth Mexican International Conference on Artificial Intelligence, 2010
Real mobile robots should be able to build an abstract representation of the physical environment, in order to navigate and work in such environment. We propose a method for integrated exploration, where mobile robot incrementally build a map of this environment while simultaneously use this map to compute the absolute robot localization, and make ...

Sensorless control of induction motor using EKF: Analysis of parameter variation on EKF performance

2016 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2016
This paper deals with the investigation of the Extended Kalman Filter (EKF) for sensorless indirect vector control of an induction motor. The prime focus is low speed operation, when the EKF somewhat presents erroneous results. The effectiveness of the EKF as a speed estimator under machine parameter variations - change in stator resistance, rotor ...

A computationally efficient EKF-vSLAM

2008 16th Mediterranean Conference on Control and Automation, 2008
This paper presents an efficient extended Kalman filter implementation of a single-camera visual simulataneous localization and mapping (vSLAM) algorithm, vSLAM is a novel algorithm for simultaneous localization and mapping problem widely studied in mobile robotics field. The algorithm is vision and odometry-based.

IMPACT OF PERTURBATION ESTIMATOR ON EKF-SLAM RESULTS

IFAC Proceedings Volumes, 2007
Abstract This paper deals with the Simultaneous Localization and Map building (SLAM) problem using an Extended Kalman Filter with Perturbation Estimator (EKFPE). The perturbation estimator is used to take systematic errors into account. These disturbance estimates are added to vehicle states in a feedback loop to improve location and map estimates ...

An EKF Based Approach to Radar Inertial Odometry

2020 IEEE International Conference on Multisensor Fusion and Integration for Intelligent Systems (MFI), 2020
Accurate localization is key for autonomous robotics. Navigation in GNSS-denied and degraded visual environment is still very challenging. Approaches based on visual sensors usually fail in conditions like darkness, direct sunlight, fog or smoke.Our approach is based on a millimeter wave FMCW radar sensor and an Inertial Measurement Unit (IMU) as both ...

EKF-based estimation of SOC and temperature in ultracapacitors

2013 10th IEEE International Conference on Control and Automation (ICCA), 2013
In this paper, simultaneous estimation of state-of-charge (SOC) and temperature is achieved by applying extended Kalman filter (EKF) algorithm with only the terminal measurement of voltage and current. For the application of EKF algorithm, a nonlinear model which consists of a voltageand-thermal-dependent equivalent circuit model and a thermal model is

EKF monocular SLAM with relocalization for laparoscopic sequences

2011 IEEE International Conference on Robotics and Automation, 2011
In recent years, research on visual SLAM has produced robust algorithms providing, in real time at 30 Hz, both the 3D model of the observed rigid scene and the 3D camera motion using as only input the gathered image sequence. These algorithms have been extensively validated in rigid human-made environments -indoor and outdoor- showing robust ...
