BILL SOFTNESS RECOGNITION METHOD AND DEVICE

A bill softness recognition method and a bill softness recognition device are provided. The method includes: receiving bills; extracting and separating the bills to make the bills enter a bill channel in a separated manner; capturing a single-bill image and a bill background image of each of the extracted bills; rolling the extracted bill to make the bill press a plurality of prearranged force sensors; acquiring effective force signals fed back from the force sensors; acquiring an inclination angle of the bill based on the single-bill image and the bill background image; determining, based on the inclination angle, the force sensor that is pressed by the bill as an effective force sensor; and judging whether the effective force signal of the effective force sensor meets a preset softness condition, and determining the bill as a soft bill if the effective force signal meets the preset softness condition.
