Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific examples and with reference to the accompanying drawings.

[0024] Aiming at the problems of interval measurement uncertainty and target mobility uncertainty, the present invention uses an interactive multi-model method to process the sampling particles of each target state in the filter on the basis of the generalized label multi-Bernoulli filter. Prediction, and then update the prediction particles by introducing the generalized likelihood function combined with the GLMB filter update strategy. On this basis, combined with a fast implementation method, combining prediction and update, only one truncation process is required for each iteration, which reduces the calculation amount of the algorithm. The present invention can effectively detect and track maneuvering multi-targets in th...

Abstract

The invention discloses a fast tracking method of an interactive multi-mode generalized label Dobernoulli under interval measurement, Combining the interactive multi-modal method with the fast algorithm, Firstly, in the framework of generalized label Dobernoulli filter, For the target sampling particle prediction phase, combined with the interval measurement generalized likelihood function, the transfer prediction of all particles to different models is realized, and then the model interaction is carried out by calculating the model weight probability, and then the model interaction particlesare updated by GLMB filter update equation. On this basis, combined with the fast implementation method, the prediction and updating are combined, only one truncation process is needed for each iteration, which reduces the computational load of the algorithm, and ultimately solves the problem of maneuvering multi-target detection and tracking.

Description

technical field [0001] The invention relates to the technical field of target tracking, in particular to a multi-Bernoulli fast tracking method for interactive multi-mode generalized labels under interval measurement. Background technique [0002] The motion of a non-maneuvering target can be described by a fixed model, but to describe the motion of a maneuvering target, it may be necessary to combine motion models with different maneuvering characteristics. As the maneuvering target tracking technology has received more and more attention, the requirements for the maneuvering target tracking technology are also getting higher and higher. Multi-maneuvering target tracking has become an extremely difficult problem in the field of target tracking. [0003] In his paper "Target Tracking Algorithm of Box Particle Generalized Label Dobernoulli Filter" (Journal of Xi'an Jiaotong University, 2017, 51(10): 107-112.), Ji Hongbing proposed a box particle generalized label Dober Effo...
