Data fusion

1 For example, sensor fusion is also known as (multi-sensor) data fusion and is a subset of information fusion.


Robotics - Control

1 The processing phase can range in complexity. At a reactive level, it may

translate raw sensor information directly into actuator commands. Sensor fusion may first be used to estimate parameters of interest

(e.g. the position of the robot's gripper) from noisy sensor data. An immediate task (such as moving the gripper in a certain direction) is inferred from these estimates. Techniques

from control theory convert the task into commands that drive the actuators.


Internet of Things - Criticism

1 Thus, massively parallel sensor fusion may undermine social

cohesion if it proves to be fundamentally incompatible with Fourth-Amendment guarantees against unreasonable search.

Sensor fusion

1 'Sensor fusion' is the combining of sensory data or data derived from sensory data from disparate sources such that the resulting information is in some sense better than would be possible when these sources were

used individually


Sensor fusion - Sensor fusion algorithms

1 Sensor fusion is a term that covers a number of methods and algorithms, including:


Inertial measurement unit - TIMU (Timing IMU) sensors

1 So these TIMU chips for Micro-PNT have integrated 3-axis gyroscope, 3-axis

accelerometer, and 3-axis magnetometer, and together with the integrated highly

accurate master timing clock it simultaneous measure the motion tracked

and combines that with timing from the synchronized clock, and with sensor fusion it makes a single chip that does absolute

position tracking, all without external transmitters/transceivers.

technology areas include: radar, active and passive electro-optical targeting systems,

navigation aids, automatic target recognition, sensor fusion, threat warning and threat

countermeasureshttps://store.theartofservice.com/the-sensor-fusion-toolkit.html

List of topics related to brain mapping - Integration

1 * Multisensory integration is the neurological process that organizes

sensation from one’s own body and the environment, thus making it possible to

use the body effectively within the environment. Specifically, it deals with

how the brain processes multiple sensory modality inputs into usable functional outputs. See also Sensor fusion, Data

fusion, and Information integration


Kalman filter - Overview of the calculation

1 The Kalman filter uses a system's dynamics model (e.g., physical laws of motion),

known control inputs to that system, and multiple sequential measurements (such as

from sensors) to form an estimate of the system's varying quantities (its State space

(controls)|state) that is better than the estimate obtained by using any one measurement alone. As such, it is a

common sensor fusion and data fusion algorithm.


Multi Autonomous Ground-robotic International Challenge - Technology

1 Key technology used by all teams was computer vision, sensor fusion, human-robot

interaction,


Non-negative matrix factorization - Relation to other techniques

1 Other extensions of NMF include joint factorisation of several data matrices and tensors where some factors are shared. Such models are useful for

sensor fusion and relational learning.


Micro air vehicle - Bio-inspiration

1 Biological systems are not only interesting to MAV engineers for their use of unsteady aerodynamics with flapping wings; they are increasingly inspiring engineers for other aspects

such as distributed sensing and acting, sensor fusion and information

processing


Defense Research and Development Organization - Command and control software and decision-making tools

1 *Radar netting and multi-sensor fusion software for linking the Indian Air Force's

network of radars and airbases which have been successfully operationalised. Other systems include sophisticated and highly

complex mission planning and C3I systems for missiles, such as the Agni and Prithvi ballistic missiles and the Brahmos cruise missile. These systems are common to all

three services as all of them utilize different variants of these missiles.


Heart monitor - Composition

1 More advanced models will offer measurements of heart rate

variability, activity, and breathing rate to assess parameters relating to

a subject's fitness. Sensor fusion algorithms allow these monitors to

detect core temperature and dehydration


Visual sensor network

1 The network generally consists of the cameras themselves, which have

some local image processing, communication and storage

capabilities, and possibly one or more central computers, where

image data from multiple cameras is further processed and sensor fusion|fused (this processing may, however,

simply take place in a distributed fashion across the cameras and their

local controllers)


Climate of Mars - Temperature

to a lesser extent 2001 Mars Odyssey's Thermal Emission Imaging

Earth microwave data


System safety - Safety engineering

1 Systems of systems, such as a modern military aircraft or fighting

ship with multiple parts and systems with multiple integration, sensor

fusion, networking and interoperable systems will require much partnering

and coordination with multiple suppliers and vendors responsible for

ensuring safety is a vital attribute planned in the overall system.


Dempster–Shafer theory - Overview

1 Often used as a method of sensor fusion, Dempster–Shafer theory is

based on two ideas: obtaining degrees of belief for one question from subjective probabilities for a related question, and Dempster's

ruleDempster, Arthur P.; A generalization of Bayesian inference,

GPS/INS - Applications

1 In general, 'GPS/INS' sensor fusion is a nonlinear filtering problem, which is commonly approached using the Extended Kalman Filter (EKF) or the

Unscented Kalman Filter (UKF)

broad range of applications such as such as intelligent sensors, sensor fusion, and sensor hub increasingly

prevalent in automotive,


Network-centric warfare - Some architectural and design challenges

1 * Accurate locational awareness is limited when maneuvering in areas where Global

Positioning System (GPS) coverage is weak or non-existent. These areas include the inside of buildings, caves, etc. as well

as built-up areas and urban canyons, which are also settings for many modern

military operations. Much work on reliable sensor fusion|fusion of positional data

from multiple sensors remains to be done.

several measurements are processed together. There may be dozens or even hundreds of

measurements. The interaction of the signals can be used for calculating new quantities that
