Sensor Fusion

Definition

Sensor fusion is the process of combining data from multiple sensors to produce more accurate, reliable, and comprehensive information than that provided by any single sensor. This technique enhances data interpretation and decision-making by integrating various types of sensor data, such as optical, thermal, and electromagnetic signals, enabling improved performance in applications like energy management.
