| 多尺度 (小波)分析具有时、频分析特性 ,把多尺度分析用于融合跟踪领域是一项值得深入研究的课题 .本文根据多尺度分析思想 ,把运动模型的动态系统分析与小波变换方法相结合 ,给出了不同尺度上的节点方差矩阵的一种快速求解方法 .在此基础上提出了一种多尺度自适应融合跟踪方法 .该方法根据目标的运动状态自动调整跟踪尺度 ,从而有效地利用检测数据 ,更准确地刻画出航迹变化 ,弥补了单一尺度的不足 ,实现了对动态目标的跟踪 . |
| 英文摘要 |
| Multi-scale (wavelet) analysis is characterized by its focus on time and frequency.It is a worthy attempt to apply the multi-scale analysis to the fusion tracking field.Based on the multi-scale analytical approach and combining the dynamic system analysis of movement model with wavelet transform method,a quick algorithm is given for node variance matrix on different scales.A multi-scale self-adaptive fusion tracking method is then presented.This method adjusts tracking scale automatically according to the state of model target.It uses detective data efficiently and more accurately to describe the variation of track;and thus it avoids the disadvantages of single scale and also realizes the tracking towards dynamic target. |
