Method and device for segmenting electric field line interface

The invention discloses a method and a device for segmenting an electric field line interface. The method comprises the following steps: acquiring electric field intensity data of each electric field line; forming a two-dimensional array of each electric field line based on the electric field intensity data of each electric field line; successively obtaining an electric field intensity distribution curve of each electric field line, a field intensity jump value of the data point and a field intensity jump curve of each electric field line based on the two-dimensional array of each electric field line; obtaining a boundary characteristic value of each electric field line based on the electric field intensity distribution curve of each electric field line and the field intensity jump curve of each electric field line; and comparing the absolute value of the field intensity jump value of each data point of each electric field line with the boundary characteristic value, determining a data point set on the interf
