Data from Insight reveals size of Mars's core

An international team of researchers studying seismic data collected by NASA's Insight spacecraft has used the data to calculate the size of Mars' core. The group plans to discuss their findings at this year's Lunar and Planetary ...

Slow motion precursors give earthquakes the fast slip

At a glacier near the South Pole, earth scientists have found evidence of a quiet, slow-motion fault slip that triggers strong, fast-slip earthquakes many miles away, according to Cornell University research published in ...

Scientists invent new sensing eye mask

From the team that invented physiology-sensing pajamas at the University of Massachusetts Amherst, now comes a new, lightweight eye mask that can unobtrusively capture pulse, eye movement and sleep signals, for example, when ...

MXene materials help photodetectors see the light

Photodetectors are the devices that convert information carried by light into an electric signal that can be processed by electronic circuits and computers. They are found in everyday devices, such as television remotes and ...

It's alive! Researchers create innovative 'living' bridge

Engineers at the University of New Hampshire have designed a unique living laboratory on a heavily traveled iconic bridge which could change the way infrastructure is viewed. The Memorial Bridge, which links Portsmouth, New ...

Sensor fusion

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. The term better in that case can mean more accurate, more complete, or more dependable, or refer to the result of an emerging view, such as stereoscopic vision (calculation of depth information by combining two-dimensional images from two cameras at slightly different viewpoints).

The data sources for a fusion process are not specified to originate from identical sensors. One can distinguish direct fusion, indirect fusion and fusion of the outputs of the former two. Direct fusion is the fusion of sensor data from a set of heterogeneous or homogeneous sensors, soft sensors, and history values of sensor data, while indirect fusion uses information sources like a priori knowledge about the environment and human input.

Sensor fusion is also known as (multi-sensor) Data fusion and is a subset of information fusion.
