Abstract

The invention discloses a device and a method for fusing sensor information. The sensor-information fusion method comprises the steps of adopting a self-adaptive weighted-data fusion algorithm to allocate corresponding weight numbers for induction information from a plurality of sensors, adopting a Kalman filtering algorithm to perform optimal estimation to the induction information of the corresponding weight numbers so as to acquire the locally fused induction information, adopting a D-S theory estimation algorithm to perform interval estimation to the uncertain induction information in the locally fused induction information, adopting a multi-Bayesian estimation algorithm to perform individual association probability distribution for the induction information after interval estimation so as to synthesize a joint posteriori probability distribution function, and utilizing the joint distribution function to output a final fusion value of the induction information. The invention has the advantages of improving the reliability, confidence and efficiency of sensor information fusion.

Description

technical field [0001] The present invention relates to the field of information processing, in particular to a sensor information fusion device and method based on IIF (Intelligent Information Fusion, intelligent information fusion). Background technique [0002] A sensor is a detection device that can feel the measured information, and can convert the detected information into electrical signals or other required forms of information output according to certain rules, so as to meet the needs of information transmission, processing, storage, display, recording and control requirements. [0003] With the rapid development of sensor technology and the emergence of a large number of multi-sensor systems, complex engineering systems have a large amount of sensing information about the environment and the dynamic process being detected. IIF is created for the problem of processing a large amount of complex sensory information. IIF is a comprehensive discipline about the best c...
