7134 与传统点目标跟踪不同,扩展目标跟踪既要估计目标的运动状态,还需估计目标的扩展状态,包括目标的形状、大小、方向等信息。 Differs from the traditional point target tracking, target tracking is to estimate target motion state, still need to the expansion of the estimated target state, including information such as shape, size, direction of the target.
7135 针对扩展目标跟踪中存在的扩展状态估计不准确和非线性问题,提出一种基于随机超曲面模型(random hypersurface model,RHM)的扩展目标伯努利滤波算法。 Based on extension in the extended target tracking state estimation are not accurate and nonlinear problems, and put forward a model based on random hypersurface (random hypersurface model, RHM) extended target Bernoulli filtering algorithm.
7136 该算法首先采用RHM对目标量测源建模; The algorithm firstly USES the RHM source modeling of target measurement;
7137 然后,在扩展目标伯努利滤波框架下,实现对单扩展目标运动状态和扩展状态的实时估计; Then, in the extended target Bernoulli filtering framework, implementation of single extension to estimate target motion state and the expansion of state;
7138 最后,引入Gamma分布以提高量测率估计的准确性。 Finally, the Gamma distribution is introduced to improve the accuracy of the measurement rate is estimated.
7139 此外,为了降低计算复杂度,在量测更新中采用距离划分来减少所有可能的划分总数。 In addition, in order to reduce the computational complexity, used in the measurement update total distance divide to reduce all possible.
7140 实验结果表明,所提滤波算法在估计目标运动状态、扩展状态和量测率等方面优于现有的滤波算法,并且可用于实际视频跟踪场景。 The experimental results show that the proposed filter algorithm to estimate target motion state and expansion rate of state and measurement is superior to the existing filtering algorithm, and can be used in the actual video tracking scenarios.
7141 针对体系需求建模中使命模型在分解时无法引入属性参考,不便于检查分解的合理性,影响模型分析效果等问题,提出了基于本体的体系使命建模及分析方法。 Mission in the work of system requirements modeling model cannot be introduced during decomposition property reference, is not convenient to check the rationality of the decomposition, the effect the model analysis, put forward the mission system modeling and analysis method based on ontology.
7142 根据使命在体系需求建模中的关键作用,定义了使命的若干属性参数,并构建了体系的使命概念模型。 According to the mission in the key role of system requirements modeling, the attribute parameter defines the mission, the mission of the conceptual model and build the system.
7143 为了使使命分解更加科学严谨,设计了使命分解算法,在分解过程中引入了使命的相关属性值。 In order to make more scientific and rigorous mission decomposition, design the mission decomposition algorithm, introduces the relevant properties of mission in the process of decomposition.
