sensor fusion

Sensor fusion is the intelligent combination of the measured values from different sensors. From this combined information of different or similar sensors, which are often interdependent, correlations and parameters for application control can be derived.

In addition, when multiple sensors of the same type are used, the accuracy of the sensor information can be improved. The result obtained from sensor fusion is better in outcome than if the readings from individual sensors were interpreted. It follows that the interpreted results are more accurate, the dependence of the physical quantities on each other is represented and their representation form can be multidimensional.

There are various mathematical methods for the interpretation and evaluation of the sensor fusion signals. These include, for example, correlating the different physical measured values or weighting them, or transforming the measured values for the purpose of analysis.

In a sensor fusion, for example, the pressure and the temperature can be combined, or the temperature and the humidity, or the distance, acceleration and velocity, and many other physical quantities.
