Abstract

In order to realize the rapid detection and imaging of dangerous goods with high dielectric constant at small and mediumsized express points, a three-dimensional imaging method for packaging inspection based on planar ECT technology was proposed; Firstly, the electrode matrix of traditional planar ECT is optimized, and a planar ECT sensor with linear detection electrode array is designed; Then, the simulation model of the package to be tested under different dielectric constants is established. During the detection, the electrode plate is placed on the top of the package and moved slowly to obtain the capacitance signal of the detection electrode plate in different areas of the package; Finally, the iso-surface method is used for partial and full 3D imaging of the object in the package. The experimental results show that the designed detection method can realize three-dimensional imaging of high water content in packaging and metal dangerous goods.
