Realization of real-time automatic target reporting system for simulant airborneweapon attacking over ground

为了弥补传统人工报靶的不足,提高航空武器对地攻击训练中的报靶效率,并为实现战场打击实时自动评估探索新思路,运用光学交汇测量原理,通过CCD成像、图像分析对比等方法,提出了航空武器对地模拟攻击实时自动报靶系统设计方法,解决了多目标动态检测算法、图像畸变校正算法、图像阈值计算及打击目标重心(质心)提取等技术问题,实现了实时对模拟打击点的测量、计算、记录和分析。实验证明:该系统对视场内光点目标的捕获能力达到了97%以上,打击点测量坐标相对误差小于0.23%。

In order to remedy the traditional target reporting, improve the efficiency of target reporting in training of airborneweapon-attacking over the ground, and put forward new method to realize real-time automatic target reporting in battlefields, the design method of the realization of real-time automatic target reporting system for simulant airborneweapon attacking over the ground was put forward by using intersection measurement method theory and adopting CCD imaging principle, image analysis method, the function of pick up all dynamic target, the function of correcting for distortional image, calculation of image threshold and method of focus（center of mass） extraction were solved, and the real-time measurement, caclulation, record and analysysis of hit points were realized. The result of experiment has proved that the capture rate of this system for light spot in the field of view is more than 97%, the relative error of hit points′ coordinate is less than 0.23%.
