实现卡尔曼滤波,可以看出,滤波过程是以不断地“预测—修正”的递推方式进行计算,先进行预测值计算,再根据观测值得到的新信息和kalman 增益(加权项),对预测值进行修正。由滤波值可以得到预测,又由预测可以得到滤波,其滤波和预测相互作用,并不要求存储任何观测数据,可以进行实时处理。-Kalman filtering, can be seen, the filtering process is constantly " forecast- Fixed" recursive mann

卡尔曼滤波器的算法C实现
最佳线性滤波理论起源于40年代美国科学家Wiener和前苏联科学家Kолмогоров等人的研究工作,后人统称为维纳滤波理论。从理论上说,维纳滤波的最大缺点是必须用到无限过去的数据,不适用于实时处理。为了克服这一缺点,60年代Kalman把状态空间模型引入滤波理论,并导出了一套递推估计算法,后人称之为卡尔曼滤波理论。卡尔曼滤波是以最小均方误差为估计的最佳准则,来寻求一套递推估计的算法,其基本思想是:采用信号与噪声的状态空间模型,利用前一时刻地估计值和现时刻的观测值来
