Abstract

The invention discloses a multi-sensor data fusion method and device. The method first encapsulates the output data of each sensor within a period of time into a data element for storage, and then stores each data element in each sensor data element set. When the data type, time and content of the two data elements are the same, change the sensor identification of one of the data elements to the sum of the two and delete the other. Data element; when the data type and time of the two data elements are the same but the data content is different, change the sensor identification of the data element with a higher sensor level to the sum of the two and delete the other data element; in the two data elements When the data types are different but the data time is the same, the data element identity of the other party is added to the data content of the two data elements respectively. The invention has the advantages of high efficiency and supports multiple data sources, and provides a new idea for multi-sensor data fusion.

Description

technical field [0001] The invention relates to a method and device for multi-sensor data fusion, belonging to the field of sensor data fusion. Background technique [0002] At present, the research on multi-sensor fusion technology mainly focuses on the decision-making aspects of multi-sensor applications, and there is less research on multi-sensor data-level fusion technology. Therefore, sensor data fusion is a promising research direction in the information field. Research on multi-sensor data fusion is of great significance. Multi-sensor data fusion technology was formed in the 1980s. It is different from general signal processing, and also different from the monitoring and measurement of single or multiple sensors. It is a higher-level comprehensive decision-making based on the measurement results of multiple sensors. process. Multi-sensor data fusion technology is a technology that comprehensively processes and optimizes the acquisition, representation and internal r...
