Sensor and Data Fusion Training Bootcamp

sensor-data-fusion-techniques-image

Sensor and data fusion technology refers to the use of multiple sensors to collect data from the same target, analyze and synthesize the collected data using computer technology, and form data with high accuracy and low redundancy to support the decision-making process.

In general, the objective of data fusion is to improve overall system performance, including:

  • Improved decision making
  • Increased detection capabilities
  • Diminished number of false alarms
  • Improved reliability

Different data fusion methods have been developed in order to optimize the overall system output in a variety of applications for which data fusion might be useful: security (humanitarian, military), medical diagnosis, environmental monitoring, remote sensing, robotics, etc.

The concept of sensor fusion attempts to replicate the capability of the central nervous system to process sensory inputs from multiple sensors simultaneously.

Sensor and data fusion has a variety of applications such as in GPS/INS. In this applications, Global Positioning System and inertial navigation system data is fused using various different methods like the extended Kalman filter (EKF), the nonlinear version of the Kalman filter which linearizes about an estimate of the current mean and covariance.

Sensor and data fusion is also useful in determining the attitude of an aircraft using low-cost sensors.

Additionally, a data fusion approach can determine the traffic state (low traffic, traffic jam, medium flow) using road side collected acoustic, image and sensor data.

Although technically not a dedicated sensor fusion method, modern Convolutional neural network based methods can simultaneously process very many channels of sensor data (such as Hyperspectral imaging with hundreds of bands and fuse relevant information to produce classification results.

The fusion of radar sensor and multi-purpose camera data is also highly relevant for automated driving. The Bosch road signature makes it possible for automated vehicles to determine their precise position and enables highly accurate and robust vehicle localization based on road features.

Sensor and data fusion has also become prominent in artificial intelligence (AI).

The AI algorithm can employ sensor fusion to use the data from one sensor to compensate for weaknesses in the data from other sensors.

Consequently, the AI algorithm can classify the relevance of each sensor to specific tasks and minimize or ignore data from sensors determined to be less important.

The AI/sensor fusion relationship has several benefits, including:

  • The AI algorithm can employ sensor fusion to use the data from one sensor to compensate for weaknesses in the data from other sensors.
  • The AI algorithm can classify the relevance of each sensor to specific tasks and minimize or ignore data from sensors determined to be less important.
  • Through continuous training at the edge or in the cloud, AI/ML algorithms can learn to identify changes in system behavior that were previously unrecognized.
  • The AI algorithm can predict possible sources of failures, enabling preventative maintenance and improving overall productivity.

Sensor and Data Fusion Training Bootcamp Course by Tonex

Sensor and Data Fusion Training Bootcamp covers technologies, tools and methods to automatically manage multi sensor data filtering, aggregation, extraction and fusing data useful to intelligence analysts and war fighters.

Learn about application of artificial neural network technology to data fusion for target recognition, airborne target recognition, activity-based intelligence, C4ISR, Electronic Warfare (EW), radar and EO-IR thermal imaging sensors, missile defense, cyber warfare, air, space and maritime surveillance, net-centric warfare, Activity-based Intelligence, effects-based operations process control, proactive maintenance and industrial automation.

Data fusion is a data analysis technique that combines and correlates data about a single subject from different sources, to be able to derive additional insights and intelligence from that data.

The intelligence extracted from data fusion makes it easier for analysts to identify potential adversaries and their targets. By organizing and collecting large volumes of collected data, relevant patterns can be recognized using data fusion.

The artificial neural network based fusion architectures are discussed along with multi-source and multi-sensor data fusion, alternative learning algorithms, parallel distributed processing, real-time automatic target recognition decisions based on performance, and large volumes of structured, unstructured data from disparate sources and low vs. high-level fusion.
