Application of Dempster-Shafer evidence theory in data fusion technology

This paper introduces the application of Dempster-Shafer evidence theory of multi-sensor data fusion technology.The multi-sensor system includes 4 types of sensors,such as acoustic sensors, vibration sensors, magnetic sensors and infrared sensors. This system acquires and processes the similar and heterogeneous sensor's signal. To present the data of processing results with the form of the probability. The function of data fusion in multi-sensor system further integration by Dempster-Shafer evidence theory. Using complementary and redundant information of multi-sensor, enhancing the effectiveness of the entire sensor system.
