卡尔曼滤波在相似材料模型数据处理中的应用

his article is about the comprehensive analysis of kalman filter model of discrete linear system. Model with similar material model data which received from industrial photogrammetry system, and calculate with Matlab, draw a conclusion that the de-noising effect of the kalman filter in similar material model data processing is obvious, and the subsidence curve can reflect more the actual situation. Then contrast analyse with the calculation of Logistic function fitting, show that the filter model is accuracy. In the end this article puts forward an idea of the combination of Logistic fuction and kalman filter model，which need further research.
