A Method for Data Fusion of Multi-Sensor
Yang Quan-sheng · Computer Technology and Development · 2008
In a measurement system with so many sensors,the accuracy of intelligent sensors is often influenced due to the various disturbances in the industry environment,which leads to the result that not all the time the data measured by a sensor is reasonable.As a result,only sensors with reasonable measure data should be picked to join the process of data fusion.In the process of the multi-sensor data fusion,the reliability degree of each sensor must be calculated before establishing the accurate relation matrix.The general method is to estimate whether the two sensors support each other with the threshold value.According to the fuzziness determining the relation matrix,a threshold interval is proposed to estimate the degree of the support among the sensors.In the end,prove that the method used in this paper is feasible and simple by an experiment.
