摘要
以圆形模块为研究对象,应用数据统计法分别提取出圆形模块及该圆形圆心的投影数据,并对这些数据进行拟合,得到函数图像,利用这些图像进行求解。建立了直接傅里叶反变换模型,在该模型中加入了卷积处理,有效降低了"噪声"效应。应用MATLAB软件进行编码,得出未知介质的几何形状。对参数标定模型精度和稳定性进行评价,设计出了新的双球型标定模块与相应的标参模型。
This paper takes the circular module as the research object.The projection data of the circular module and the circle center are extract respectively,and we use the function image obtained by these data to solve the problem.We effectively reduce the noise effect by establishing a direct inverse Fourier transform model with convolution processing.The geometry of the unknown medium is obtained by the MATLAB software.After evaluating the accuracy and stability of the parameter calibration model,a new double ball calibration module and its corresponding parameter calibration model are designed.
