摘要: 在基于图像的目标跟踪系统中,跟踪器延迟对系统的稳定性和跟踪精度产生不利影响.通过对光电平台伺服系统的理想控制指令的分析,给出了一种基于自适应估计的跟踪器延迟补偿方法.该方法采用自适应估计器快速估计目标速度,预测目标位置,同时结合无人机位置和姿态信息预测控制指令实现延迟补偿.仿真结果表明:该方法在目标机动和载机机动情况下能够有效提高光电平台的跟踪精度.

Abstract: A harmful effect on stability and tracking accuracy of the system was produced by the time-delay of tracker in an image-based target tracking system. Analyzing the ideal control command of the electro-optical platform servo system, a delay compensation method based on adaptive estimation was proposed. This method used target position and unmanned aerial vehicle position and attitude to predict the control signals of the electro-optical platform. The target velocity was estimated by an adaptive estimation rapidly. The results of simulation show that the tracking accuracy of the electro-optic platform as the target maneuvers and the unmanned aerial vehicle maneuvers can be improved effectively.
