Parallel Filtering-Communication mode: 网络通讯/融合与节点滤波计算同步进行 网络协同“一致性”研究如火如荼十余载,源起复杂网络控制,后发展至分布式滤波和跟踪。但是现有所有的分布式滤波基本都是“滤波-融合-再滤波-再融合”这种“你方唱罢我登台,轮番上阵”的串行方式,或者说“鸡生蛋,蛋孵鸡”这种相互依赖迭代模式:所融合的对象就是滤波结果,而下一轮滤波的先验就是融合结果。 0-1的突破: 提出了 “一边滤波一边通讯融合”并行模式(即网络通讯融合与节点滤波计算同步进行, Parallel Filtering-Communication mode ) ,难点在于:没有鸡(滤波)怎么来的蛋(融合)?没有蛋(融合)又怎么来的鸡(滤波)?这就是我们Engineer们 施展拳脚 了。。。 团队近期两篇论文 (全世界独此两篇?) : 第1篇基于粒子滤波,借助Importance Sampling方法,巧妙实现了 高度 Parallel Filtering-Communication ; 第2篇基于高斯混合GM滤波, Parallel Filtering-Communication 实现难度较大,所实现的融合对象仅仅是目标数cardinality的估计,融合层次教浅有待进一步研究。 两个工作分别对最具代表性的两类滤波后验近似形式进行了“滤波与通信并行”机制设计,可以推广到诸多以粒子滤波和高斯混合为基底的其他多传感实时滤波器设计。 网络通讯与节点滤波计算同步进行的优势自不必说, 甚至有些场景下是唯一选择 !比 如局部节点的滤波计算占据了整个传感器扫描周期,根本没有剩余时间去搞通讯和信息融合 ---- 而这将伴随着传感器扫描周期越来越快变得普遍。。即使有些剩余时间,因为平行通讯可以完成更多周期的信息交换,传播更远,网络收益更大。。 1 A Distributed Particle-PHD Filter with Arithmetic-Average PHD Fusion Tiancheng Li , Franz Hlawatsch (Submitted on 17 Dec 2017 ( v1 ), last revised 20 Dec 2018 (this version, v2)) We propose a particle-based distributed PHD filter for tracking an unknown, time-varying number of targets. To reduce communication, the local PHD filters at neighboring sensors communicate Gaussian mixture (GM) parameters. In contrast to most existing distributed PHD filters, our filter employs an `arithmetic average' fusion. For particles--GM conversion, we use a method that avoids particle clustering and enables a significance-based pruning of the GM components. For GM--particles conversion, we develop an importance sampling based method that enables a parallelization of filtering and dissemination/fusion operations . The proposed distributed particle-PHD filter is able to integrate GM-based local PHD filters. Simulations demonstrate the excellent performance and small communication and computation requirements of our filter.

A Parallel Filtering-Communication based Cardinality Consensus Approach for Real-time Distributed PHD Filtering Tiancheng Li ; Mahendra Mallick ; Quan Pan Abstract: This paper proposes a new cardinality consensus (CC) approach called “prior-CC” to distributed probability hypothesis density (PHD) filtering based on a decentralized sensor network. In our approach, network-wide average consensus is sought with respect to the prior cardinality estimate. Unlike existing serial filtering-communication approaches, the prior-CC scheme allows the internode communication to be performed in parallel with the local filter calculation and requires only a small amount of interfacing fusion calculation and communication. This enables real-time filtering that minimizes data delay and is of great significance in realistic tracking systems. We provide details of the Gaussian mixture implementation of the proposed prior-CC-PHD filter based on a diffuse target birth model and analyze the filtering-communication parallelization. In addition, we evaluate the gain of the prior-CC scheme with respect to the filtering accuracy in comparison with the standard CC scheme via simulations using a stationary linear sensor network and a dynamic nonlinear sensor network, respectively.

在几乎所有(有关传感器的)参数和(有关目标的)模型条件均未知的情况下,怎么做到:采用一个无线传感网(节点之间还可能非相互独立)去探测、跟踪未知数目的一群目标? 传统上来说,就是采用一个传感器去跟踪估计一个目标,滤波器的设计也往往要基于准确的传感器参数(比如噪声统计特性、杂波率、漏检率等)和相对准确的目标模型信息(否则就需要构建多模型或者自适应模型进行近似或学习逼近),这些所涉及的参数和模型,任何一个未知都会给估计跟踪带来很大困难!比如常常借助于有效的系统辨识或者参数学习机制等等,滤波器才能够有效运行。 那么一堆传感器(特别是分布式网络链接起来)和一堆目标呐,什么属性都完全未知的时候呐?不仅仅是数量的升级,还可能带来传感器之间和目标之间的交互关联等复杂问题!这就使得多传感器多目标跟踪成为一个更为棘手的难题!大道至简,难到一定程度的问题也许可以用简单的方法解决! 请看下文所提出的一中 Lazy Networking Approach: 轻松网络协作方法,只需要Flooding 和 Clustering两个操作, 就可以应对各种参数和模型未知,方法简单计算快、效果可以胜过提供了真实参数和模型信息的传统滤波器(也就是先不让滤波器去操心参数和模型未知的问题,给它们最理想的条件)! Distributed Flooding-then-Clustering: A Lazy Networking Approach for Distributed Multiple Target Tracking Authors: Tiancheng Li ; Juan M Corchado ; Huimin Chen Abstract: We propose a straightforward but efficient networking approach to distributed multi-target tracking, which is free of ingenious target model design. We confront two challenges: One is from the lack of statistical knowledge about the target appearance/disappearance and movement, and about the sensors, e.g., the rates of clutter and misdetection; The other is from the severely limited computing and communication capability of the low-powered sensors, which may prevent them from running a full-fledged tracker/filter. To overcome these challenges, a flooding-then-clustering (FTC) approach is proposed which comprises two components: a distributed flooding scheme for iteratively sharing the measurements between sensors and a clustering-for-filtering approach for target detection and position estimation from the local aggregated measurements. We compare the FTC approach with cutting edge distributed probability hypothesis density (PHD) filters that are modeled with appropriate statistical knowledge about the target motion and the sensors. A series of simulation studies using either linear or nonlinear sensors, have been presented to verify the effectiveness of the FTC approach.
