| Abstract: | The paper describes the arith model of kalman filter and the method of confirming its initial values in details. Then introduces the application of kalman filter in dynamic surveying system, ascertain the arith model by anylazing the noise feature of the data, and achieves the functions in matlab. In conclusion of the application, kalman filter has high precision in forcasting and can be used in deformation monitoring and prediction of dam |
