What is sensor fusion software?

The sensor fusion software BSX provides orientation information in form of quaternion or Euler angles. The algorithm fuses the sensor raw data from 3-axis accelerometer, 3-axis geomagnetic sensor and 3-axis gyroscope in an intelligent way to improve each sensor's output.

What are the types of sensor fusion strategies?

With respect to the abstraction level of data processing, Multi-sensor fusion has been classified into three categories [6,18]: fusion at the data-level, fusion at the feature-level, and fusion at the decision-level.

How does a sensor fusion work?

Essentially, sensor fusion aims to overcome the limitations of individual sensors by gathering and fusing data from multiple sensors to produce more reliable information with less uncertainty. This more robust information can then be used to make decisions or take certain actions.

What is sensor fusion in machine learning?

Sensor fusion is the process of combining sensor data or data derived from disparate sources such that the resulting information has less uncertainty than would be possible when these sources were used individually.
