介绍一种利用数字图像注入构建目标环境来完成目标捕获跟踪仿真训练任务的新方法,该方法通过模拟目标的理论航迹,实时接收并解算编码器输出值,同时与目标的运动方程做综合处理,计算出目标的位置信息,最后在背景中合成目标后按照红外图像的格式将数字图像注入到数字图像处理系统中。该方法可以在不开启红外相机的情况下,方便地完成手动及自动跟踪的训练任务,节约了训练成本,并已成功运用到某光电跟瞄设备的仿真训练系统中。

A simulation train method based on digital image injection was presented to complete the training task of capturing and tracking target and to build the target environment.By simulating the target flight path,the output values of an encoder were received and calculated in real time,a comprehensive treatment with the equations of target motion was completed,and the target location information in images was worked out.Then,the digital image was injected into a digital image processing system according to the format of infrared images after synthesizing the target into the background.This method can simply and conveniently complete the tracking tasks in manual and automatic methods without using the infrared cameras,and can significantly reduce training costs.The method has been successfully used in the simulation training system of a photoelectric tracking and pointing apparatus.
