基于曲线拟合的动目标位置预计方法

针对光电跟踪系统转入自动跟踪模式过程中目标图像提取困难的问题,探讨基于目标位置动态预计的过程控制方法,通过曲线拟合算法对目标运动轨迹进行预计。算法实现需依据观测次数必须大大超过待定参数、拟合点数选择应根据目标运动速度和外推点数决定、采样频率应随目标运动速度提高而提高的原则。经实验验证,该方法计算过程简单,易于工程实现,效果明显。

Method on Position Prediction of Curve-Fitting-Based Moving-Target

Aiming at problems of difficult target image identification during transition from optoelectronic tracking system to automatic tracking mode, discuss process control method based on target-position prediction, which predicts the target move through curve fitting. The algorithm is implemented according to the follows: the observation frequency should exceed the required parameter in great deal, the number of the fitting points should be selected based on both the target velocity and the number of points to b...
