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 ...

Too many airplane systems rely on too few sensors

The apparent connection between fatal airplane crashes in Indonesia and Ethiopia centers around the failure of a single sensor. I know what that's like: A few years ago, while I was flying a Cessna 182-RG from Albany, New ...

Core technology for ultra-small 3-D image sensor

A KAIST research team developed a silicon optical phased array (OPA) chip, which can be a core component for three-dimensional image sensors. This research was co-led by Ph.D. candidate Seong-Hwan Kim and Dr. Jong-Bum You ...

Ship disasters avoided with big data statistics techniques

Companies can save millions by using advanced statistical methods to extract information from large amounts of collected data. One company that has adopted this new way of thinking is the international industrial group ABB. ...

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.
