摘要
电阻层析成像技术在两相流测量中应用越来越广泛,在图像重建过程中,第一步要进行软场剖分。因为测量数据是离散的,需要采用有限元方法把连续的场离散化,通过有限元方法把场离散为多个三角形,根据分割的圈数来确定三角形的个数。为了验证分割的正确性及适用性,再用实际采集数据和滤波反投影算法进行场中物体位置的重建。
Electrical Resistance Tomography has been widely applied in the two - phase flow measurement. During the measurement process, the first step is to split the soft field. Because the measurement data is discrete, a continuous field need to be discretized by the finite element method. The method is used to divide the field for many discrete triangle. The number of triangle is decided to the number of Segmentation laps. In order to verify the accuracy and applicability of partition, we use the actual collection of data and the filtered back projection algorithm to reconstruct the object＇s position in the field.
