中文摘要 |
针对基本粒子滤波方法存在的权值退化和计算效率低问题, 提出了一种基于信息分享机制的粒子滤波算法. 该方法将粒子群优化算法和蚁群优化算法的优化思想共同作用到粒子更新中, 实现粒子之间信息共享, 从而增强粒子的多样性和最优估计能力. 同时分析了该算法的收敛性. 视觉跟踪实验表明, 该算法能用较少的粒子实现单目标和多目标跟踪, 综合跟踪性能优于基本粒子滤波和基于粒子群优化的粒子滤波方法, 验证了本算法的有效性. |
英文摘要 |
To deal with the weight-degeneracy and computation efficiency in particle filter, we propose a novel particle filter algorithm based on the information-shared mechanism. This method combines particle swarm optimization and ant colony optimization to update particles to fully share the population information. The particles diversity is recovered and the estimation precision is improved. The convergence of this algorithm is analyzed. Visual tracking experiments show that the proposed algorithm realizes both single-object tracking and multi-object tracking with fewer particles and better comprehensive tracking-performance than classic particle filters and the particle filter based on particle-swarm optimization. |
