Abstract

The invention discloses a multi-sensor data weighted fusion method, which is used for a distributed multi-sensor detection system and belongs to the technical field of multi-sensor information fusion.The method comprising the steps of 1) taking i (i=1, 2, 3,.., N) and all the data before the k-th time as a group, filtering and correcting the k-th measurement data according to the group data, replacing the k-th measurement data with the corrected data, and participating in the correction of the next measurement data; 2) carrying out weighted fusion among the N sensors on the corrected measurement data; 3) combining all the fused data into a fused data group, and performing secondary weighting fusion on the data of the fused data group. The method corrects the measured data of sensors and accurately calculates the data fusion weights of different sensors, so as to improve the data fusion accuracy of sensors, and make the results of distributed multi-sensor fusion closer to the actual situation and more reliable.

Description

technical field [0001] The invention relates to the field of multi-sensor information fusion, in particular to a multi-sensor data weighted fusion method. Background technique [0002] In a distributed multi-sensor detection system, multiple sensors are often used to measure the same parameter repeatedly, and the detection accuracy of the system is improved through data fusion. There are many methods for data fusion. Compared with the subjective arbitrariness and modeling limitations in the practical application of Bayesian decision-making and neural network and other fusion technologies, the weighted fusion method does not require prior information and has relatively high fusion accuracy. advantages have received widespread attention. However, the multi-sensor data weighted fusion methods in the prior art all use the original measurement data of the sensors for inter-sensor data fusion, and do not consider filtering the original measurement data of the sensors, resulting i...
