摘要
针对天幕立靶弹着点坐标的测量问题,提出一种基于解析几何法的弹着点坐标测量算法。以天幕立靶为基础,建立弹着点坐标系,分别利用几何三角法和解析几何法推导简单双"N"形天幕立靶弹着点坐标测量公式,并给出了计算实例。分析结果证明:2种方法中,几何三角法适用于比较简单规则的双"N"形光幕,而解析几何法容易编制程序,适应于各种幕形。
According to the problem of the projectiles coordinates measurement, presents an algorithm with use of the analytic geometry theories. The measuring coordinate system was established in sky screens vertical target, and the derivative process of projectiles coordinates measuring formulas of simple double N-shape light screens was presented using triangulation and analytic geometry, and a computation example was given together. The analysis result shows that geometry triangles method is suitable to simple and regular dual N-shape light screens, and analytic geometry method is easy for compiling program and is suitable for varied screen shape.
