| 摘要: |
| 针对传统成像系统大视场连续跟踪的问题,提出一种新的基于空间多路重叠成像技术的可直接判定宽视场中目标位置的目标跟踪方法,以实现大范围持久监视及多目标跟踪。首先,分析了多路成像探测、跟踪机理,提出利用球面透镜阵列设计一种空间多路、共焦平面、宽视场凝视成像系统结构,各透镜单元对应的视场之间有特定的空间重叠编码关系,以便同时成像之后解算目标位置。其次,重点研究了运动多目标解码跟踪原理,在提取所有重叠空间目标像点后,按照位置和速度判断准则对重叠空间目标像点进行分类,然后在这个分类集合上解码目标所在位置。最后,对目标解码算法做了仿真,结果表明,此方法能很好地实现在宽视场中对目标的解码跟踪。 |

| Abstract: |
| The traditional imaging system has some difficulty in tracking targets continuously over a large field of view. Therefore, we propose what we believe to be a novel multi-target tracking method that uses spatially multi-plexed superposition imaging, with which multiple targets can be directly located in a wide field of view, thus a-chieving a wide range of persistent surveillance and multi-target tracking. Then we design a staring imaging architec-ture with spatially multiplexed, confocal plane and wide field of view by using the spherical lens array;the staring imaging architecture we designed has overlap encoding relationship among the subfields of view of the lens unit so as to calculate the position of the target after simultaneous imaging. After analyzing the multiplexed imaging detection and tracking principles, we extract the pixels of all spatially superposed images of moving multi-targets and classify them according to their location and velocity judgment criteria and then decode the target location with the classifi-cation set. Finally we simulate the target decoding algorithm; the simulation results, given in Tables 1 and 2 and Figs. 5 through 8, and their analysis show preliminarily that our multi-target tracking method can effectively decode and track multiple targets in a wide field of view. |
