| 摘 要： | 为了有效地提高目标的捕获概率,进行红外图像目标跟踪时,必须预测目标的质心和姿态.采用CMAC估计器可以有效地解决常用预测算法运算量与预测精度之间的矛盾.CMAC估计器先用线性模型进行训练,然后预测目标的质心和姿态.CMAC每帧用实际误差训练一次,以减少其预测误差.CMAC具有很高的预测精度,且运算量少,适应目标跟踪的实时处理.实验表明:CMAC能精确预测目标的质心和姿态,适应模型变化,具有鲁棒性.

| Abstract: | The centroid and attitude of target must be predicted in target tracking of IR image for increasing capture probability. CMAC estimator can effectually resolve conflict between operational counts and predicting precision. CMAC estimator is trained with a linear model, then the centroid and attitude are predicted. It is trained once by actual error in each frame to reduce the estimate error. CMAC has excellent predicting precision and small operational counts, it adapts to real time processing for target tracking. The experimental results show that CMAC can accurately estimate the centroid and attitude of target. It adapts to change of model and has robustness. |
