Embodiment Construction

[0021] refer to figure 1 . According to the present invention, in order to better understand the present invention, the characteristics and classification of multi-sensor measurement information are analyzed first. Track initiation and maintenance, track trimming and confirmation, assumption generation and management, track updating and merging, and track management and output are performed respectively. Set track initiation and maintenance module, track pruning and confirmation module, hypothesis generation and management module, track updating and merging module and track management output module in the heterogeneous multi-sensor multi-target tracking system; in order to reduce the follow-up calculation , the track initiation and maintenance module first performs rough classification of the measurement data according to the attribute characteristics of the received measurement data, and then performs rough correlation of position and grid according to the rough classificati...

Abstract

The invention proposes a heterogeneous multi-sensor multi-target tracking method, which can quickly start the target track, reduce the calculation amount, and improve the tracking accuracy and continuity of the track. The present invention is realized through the following technical solutions: a track initiation and maintenance module, a track pruning and confirmation module, a hypothesis generation and management module, a track updating and merging module and a track tracking module are set in a heterogeneous multi-sensor multi-target tracking system. The track management output module, the track start and maintenance module performs rough classification of the measurement data according to the attribute characteristics of the measurement data and the position grid. Points are sent to the track pruning and confirmation module as candidate points, the track confirmed by the sequence probability ratio test is sent to the hypothesis generation and management module for track clustering and hypothesis generation, and the target filter is determined by the track update and merge module Model, filter and update the track, and output the latest covariance information through the track management output module.

Description

technical field [0001] The present invention relates to heterogeneous multi-sensor fusion technology in the field of multi-target tracking, such as robots and intelligent instrument systems, information processing, image analysis and understanding, target detection and tracking, automatic target recognition, multi-source image compounding, and heterogeneous multi-sensor multi-target Tracking method. Background technique [0002] With the rapid development of information theory, cybernetics, computer technology, network technology, and sensor technology, the information entering the system has the characteristics of large amount of data, multiple sources, and multiple levels of correlation. Therefore, in the information processing center, the simple accumulation of multi-source observation information will not be allowed. The information processing center should effectively fuse and process multi-source observation information. The outstanding advantages and great success o...
