| 摘 要： | 电容层析成像系统重建图像前要对电容测量值进行归一化处理.对于已知介电常数的成像对象,电容测量值采用0-1校验法进行归一化处理;对于未知介电常数的成像对象,电容测量值采用仿真校验法进行归一化处理,仿真结果表明,可获得很好的重建图像质量.

| Abstract: | The measured capacitances of electrical capacitance tomography system are usually normalized before used for image reconstruction.For knowing permittivity tomography target,the measured capacitances are normalized by 0-1 test.For unknown permittivity tomography target,the measured capacitances are normalized by simulated test.Simulation results show that the quality of reconstructed image satisfactory. |
