- A multi - target data association approach for road vehicle tracking
一种用于道路车辆跟踪的多目标数据关联方法 - The fuzzy probabilistic data association of multiple targets tracking is presented in this paper , which define a target ? uzzy set on the measurement set at time k and then use fuzzy least mean square error method to estimate target states
给出了一种多目标跟踪的模糊概率数据关联方法，该方法在k时刻的回波集上定义一个目标模糊集，表示回波与目标之间的模糊关系。然后基于目标模糊集，利用模糊最小均方误差估计方法对目标状态作出估计。 - By employing the state - space model for pulse trains , kalman filter and probabilistic data association , the thesis develops a deinterleaving algorithm for tracking mode in chapter 5 . the interacting multiple models ( imm ) approach is implemented to simultaneously estimate the pulse train pris of multiple emitters
论文第五章引入了基于卡尔曼滤波和概率数据关联方法进行脉冲列分析和去交错的研究，为辐射源跟踪状态下的去交错技术提供了理论依据和评估标准。 - The methods of data association and tracking beginning and ending to single and multiple targets tracking in the multi - echo environment is listed . at the end of the thesis , a method is introduced , which is that based on the most closed principle , without the chosen echo , the current forecasting values added yawp based upon the former state values is considered as the target state estimated value . the value is an input of observation equation , the output of the observation equation is considered a chosen echo . and the method is validated in the simulation results
针对多目标跟踪问题,首先对多目标跟踪的原理和跟踪门的形成方法进行了概述,并对多回波环境下单目标跟踪和多目标跟踪的常用的数据关联方法和跟踪起始、跟踪终结方法进行了介绍,在本文的后半部分,对多目标的运动状态进行了仿真研究,提出了一种目标状态估计方法,该种方法的思想是当前时刻如果目标跟踪门内没有所期望的候选回波,首先计算出目标在前一时刻的运动状态下对当前时刻的预测值,并将该值叠加上系统噪声作为量测方程输入值,然后将观测值作为候选回波对目标进行状态估计。 - In this paper , we describe the study background , meaning and methods of passive acoustic detective network , summarize the basic theories and methods of target tracking and data association , analyze some tipical data association algorithms include the nearest neighbor algorithm ( nn ) , probabilistic data association filtering ( pdaf ) , joint probabilistic data association filtering ( jpdaf ) , multiple hypothesis tracking ( mht ) , and multidimensional s - d assignment algorithm . 2 . in detective network , sometimes a surveillance region have only single sensor
