一种车载光电平台图像跟踪系统设计

摘要

For guiding and attacking moving target accurately, design a set of new image tracking system to adapt to the platform. Based on the principle of image tracking system, discussed the complex technology of background tracking, update mechanism of the template, tracking technology of low contrast of dim and small target, memory tracking function, the typical target tracking function and so on.This paper introduced the measures taken, such as gate drift compensation, the goal of recapture and similar objective judgment,and completed tracking test of the photoelectric platform image tracking system on artillery reconnaissance vehicle. The results show that: the improved method of this system’s tracker is effective, tracking effect increased significantly.%为了对活动目标进行精确引导打击，设计一套新的图像跟踪系统以适应该平台。基于图像跟踪系统原理，论述了复杂背景下的跟踪技术、模板更新机制、低对比度下对弱小目标的跟踪技术、记忆跟踪功能以及对典型目标的跟踪功能等多项技术。介绍了所采取的波门漂移补偿、目标重新捕获和相似目标判断等措施，并以炮兵侦察车搭载该光电平台图像跟踪系统进行了多批次的跟踪试验。试验结果表明：该系统跟踪器的改进方法有效，整体跟踪效果提升显著。
