Normalisation Approach for Capacitance Tomography Measurement Data

电容层析系统重建图像前通常要对电容测量值作归一化处理。目前通用的是基于并联模型的归一化处理方法。本文采用串联模型对测量数据进行了归一化处理 ,仿真结果表明 ,采用基于串联模型的归一化处理方法 ,可获得更好的重建图像质量。

The measured capacitances of electrical capacitance tomography system are usually normalised before used for image reconstruction. The conventional normalisation approach is based on parallel sensor model. In this paper, the measured capacitances are normalised using an approach based on series sensor model. Simulation results show that the quality of reconstructed images can be improved with the normalisation approach based on series sensor model
