对制导系统来说,常常需要选择目标上的薄弱部位或要害部位进行瞄准以增强杀伤效果。瞄准点是根据对目标的预先分析后确定的井将其预置于参考图中。在实时图象中选择瞄准点时应计算实时图象对于参考图在透视角、目标旋转角、放大量等方面的变化,并消除这些变化对瞄准点计算准确性的影响,最后,计算瞄准点的位置。本文是在上述思路基础上通过实践后写成的。 Of the guidance system, often need to select the target of the weak parts or key parts targeted to enhance the killing effect. The aiming point is preset on the reference map according to the well that has been pre-analyzed for the target. When selecting the aiming point in the real-time image, the changes of the reference image in the perspective, the target rotation angle, the magnification and so on should be calculated and the influence of these changes on the accuracy of the aiming point should be eliminated. Finally, s position. This article is written on the basis of the above ideas through practice.
