Embodiment Construction

[0038] The present invention will be further described below with reference to the accompanying drawings.

[0039] The specific steps of the multi-sensor track fusion method that uses the target visibility to achieve track management are as follows:

[0040] Step 1, C Sensor (Radar) Adopts the Integrated Probability Data Association (IPDA) Algorithm to track the respective track, and compare the target visibility of tracking tracks and track upload conditions, will meet trail upload The conditions of the condition are each initial track set, uploaded to the integrated center, c is the number of sensors. Each track information in the initial track concentration includes state estimation, error covariance and target visibility. The target visibility is embodied in the form of probability. Assign 2 assignments to P; the first initial track collector is the primary initial track set τ, the first initial track set is used as the secondary initial track set η. The primary initial track ...

Abstract

The invention discloses a multi-sensor track fusion method for realizing track management by utilizing target visibility. The existing multi-sensor track fusion method uploads all possible tracks to the fusion center, which requires a large amount of communication and complex calculations. The present invention is as follows: 1. Two track sets are selected as the main track set and the auxiliary track set respectively. 2. The fusion center performs track association fusion on each track in the main track set and each track in the auxiliary track set respectively, to obtain the final fused track set. 3. Divide the trajectories in the fusion trajectories into target trajectories, terminated trajectories, and unknown identity trajectories. The invention can reduce the number of tracks sent by the sensor to the fusion center, reduce the communication amount between the sensor and the fusion center, and reduce the calculation amount of the fusion center. The track management function of the present invention can further speed up the confirmation of the target track in the fusion center, suppress false tracks, reduce the interference of false tracks on track association and fusion, and perform better in complex environments.

Description

Technical field [0001] The present invention belongs to the multi-sensor track association and the field of fusion technology, and more particularly to multi-sensor track fusion methods that utilize target visibility to realize track management, to solve multi-sensor tracks in complex environments such as high clutter, high leaks. Fusion issues can effectively improve the multi-sensor target tracking problem in complex environments, the target track confirmation speed of the integration center, and reduce the number of false tracks. Background technique [0002] Multi-sensor target tracking in complex environments is technically complicated, and multi-sensor target tracking generally has two system structures, which are generally divided into centralized systems and distributed systems. Since centralized integration has defects such as high communication cost, large amount of calculation and unstable system, generally adopted distributed systems as multi-sensor target tracking so...
