基于数字微镜阵列的协同目标跟踪系统设计

Design of collaborative target tracking system using digital micro-mirror device

  • 摘要: 针对多镜头目标跟踪系统协同性差及单镜头系统目标跟踪观测过程中视场小、无法实现宽视场跟踪的现状,设计了能同时实现宽视场跟踪窄视场局部目标检测的协同跟踪系统。该系统基于数字微镜阵列高反射率、高性能视场分割的特点。验证实验中,宽窄视场分割系统实现了50 ms的协同成像周期;窄视场像中心调整系统不超过2%的绝对位置误差,为局部目标光束中心难以与窄视场成像系统视轴重合问题的解决提供了实验依据。

     

    Abstract: Aiming at the situation that the multi-lens target tracking systems have poor collaboration and the single-lens systems have narrow tracking view field which cannot realize wide field tracking, a coordination tracking system which can track target in wide field and observe local target simultaneously was designed. The system, based on the performance of high reflectivity and field segmentation of digital micro-mirror device (DMD), has good practicability, great realtime performance and simple structure etc. In validation experiments, the width field segmentation system realizes 50ms synergistic imaging cycle, and the less than 2% absolute position error of narrow filed image center adjustment system can make contributions to the solution of overlap problem between local targets beam center and narrow filed imaging system-s axis.
