Description

technical field

[0001] The invention belongs to the technical field of sensor applications, and relates to the technical field of capacitive sensor applications, in particular to a positioning method for imaging reconstruction based on touch screen application iterative algorithms. Background technique

[0002] Capacitance imaging technology began to develop in the 1980s. Through the use of specially designed sensitive space array electrodes, the information of the sensitive field is obtained in a non-invasive or non-contact method, and the distribution of the medium in a certain section in the field is reproduced by the method of image reconstruction. State, and give the results of medium distribution in the form of images, among them, Electrical Capacitance Tomography (ECT) is a new monitoring technology that can visualize the distribution of medium in pipeline space.

[0003] The basic principle of ECT is to install capacitive sensors around industrial pipelines to measur...
