摘　　要：在飞行器多发短间隔或多发齐射攻击目标的试验中,快速准确地计算出弹着点位置对现场指挥决策意义十分重大。首先选取单目摄像测量系统中飞行器命中目标时刻的特定影像,基于点位判读结果,提出一种基于规则形状模拟靶的弹着点快速计算方法。以长方形加十字靶心为例,针对有靶心和靶心炸毁两种情形,采用同帧画幅和标识物建立了弹着点计算模型,并给出了两种计算模型的误差快速修正方法。通过仿真分析和实际图像计算表明,这种计算方法相对简单,采用同帧画幅抵消了一定量的系统误差,定位速度快,具有良好的工程应用价值。Quickly and exactly impact point calculation is very important for spot command and decision in the multiple aircrafts launching test with short interval or salvo. Firstly, the shoot time special image of aircraft hitting target form the singlevision videometric system was selected. Then an impact point quickly calculation method based on regular shape simulationtarget was proposed using the location judge result. Taking the rectangle with cross center as the example, the impact pointcalculation model was established based on same-frame film and calibration aiming at the good center and destroyed center.Finally, the quickly error correction methods for the two calculation models were given. The simulation and test images validation results show that the proposed method is comparatively simple and can counteract some system error in the same-framefilm. The method can provide results quickly and can be used in the engineering well.
