Multi-sensor integration

Definition

Multi-sensor integration refers to the process of combining data from multiple sensors to enhance the perception and understanding of an environment. By merging information from different sources, such as vision, sound, or touch, this technique improves the accuracy and reliability of data interpretation, leading to better decision-making in robotic systems. This is particularly important for vision sensors, as they provide critical visual information that, when integrated with other sensor data, results in a more comprehensive view of the surroundings.
