Embodiment Construction

[0028] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.

[0029] The working principle of data fusion can be summarized as: the use of computer technology to automatically analyze the observation information of several sensors obtained in time series under certain criteria, and the information processing process of completing the required decision-making and estimation tasks. From this level, it can be seen that the basis of data fusion is each sensor, the processing object is the multi-source information provided by the sensor, and the core is to coordinate, optimize and comprehensively process various information to reach a decision.

Abstract

The invention discloses a multi-sensor data fusion method, which comprises the following steps of: removing dirty data through coarse clustering and fine clustering, associating data with relatively high credibility, performing space-time alignment on target data in the same cluster, performing identity judgment on the target data after the space-time alignment, and performing data fusion on the target data after the space-time alignment. And deleting the target data which do not meet the identity from the cluster, and finally fusing the target data which passes the identity judgment in the cluster. According to the method, data fusion of a plurality of sensors and a plurality of targets is realized, the calculation amount of space-time alignment and identity judgment is reduced, the data fusion precision is effectively improved, and a relatively large error is avoided.

Description

technical field [0001] The present application belongs to the technical field of data fusion, and in particular relates to a multi-sensor data fusion method. Background technique [0002] Data fusion is to obtain the resource data of multiple sensors in the detection system, rationally control and use various observation target information of the system, and combine complementary information in space and time according to optimization criteria to achieve consensus on things and situations Sexual explanation and description, and send the fused target information to the upper-level business system for perception analysis and threat analysis. [0003] The existing technology is based on the target data reported by multiple sensors for data fusion. If the sensor report is a point track, it cannot be automatically fused after the navigation is established. The idea of ​​data fusion in this application is to fuse the same target information on other sensors based on the target in...
