摘要
为实现对快速飞行目标的稳定跟踪,必须提高红外测量系统的实时信号处理速度和伺服系统闭环控制跟踪精度.因此,在新型红外成像测量系统设计中,提出了采用了 DSP 高速图像处理、双边缘跟踪等方法,提高系统成像跟踪处理器快速性和系统带宽等性能.提出伺服系统采用速度滞后和加速度滞后补偿,构成等效复合控制的方法,解决了红外跟踪器图像传输的滞后时延对系统跟踪精度的影响.实际应用表明,红外成像测量系统稳定跟踪能力大大提高.
The real-time processing speed and closed-loop control tracking accuracy of servo system based on closed-loop control must be increased in order to track flying object stably.Therefore,high-speed image processing based on DSP and twin-edge tracking is adopted in the design of new type of infrared imaging measuring system to improve the speed of imaging tracking processor,bandwidth of system,and so on.A method that adopts velocity lag compensation and acceleration lag compensation to form equivalent compound controlling in servo system is presented.The method eliminates the effect caused by time delay of image transmission lag.Applications show that stable tracing ability of infrared imaging measuring system is improved greatly.
