卡尔曼滤波在相似材料模型数据处理中的应用
首发时间:2010-09-07
摘要:综合分析离散线性系统的卡尔曼滤波模型,针对工业近景摄影系统所获得的相似材料模型数据进行建模,并运用Matlab软件进行编程求解。得出卡尔曼滤波在相似材料模型数据处理中具有明显的去噪效果,其下沉曲线更能反映模拟的实际情况。结合Logistic函数拟合对比分析,说明此滤波模型的准确性。提出将Logistic函数拟合与卡尔曼滤波模型相结合的设想,有待进一步研究。

The Application of Kalman Filter in Similar Material Model Data Processing
Abstract:This 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.
Keywords: industrial photogrammetry system kalman filter similar material model dynamic subsidence
