Bill inspection method, device, terminal apparatus and storage medium

Abstract

The invention discloses a bill inspection method, device, terminal apparatus and a storage medium. According to the method, to-be-inspected bill images are inputted into a trained bill identificationmodel, so that the types, amounts and serial numbers of bills are identified; the identified data are compared with preset data; if bill information totally identical with the identified data exists,it is judged that the bills of the to-be-inspected bill images are repeated bills; and if bill information of which the type and serial number are identical with the identified data and of which the amount is different from the identified data exists, it is judged that a counterfeit bill exists in the bills of the to-be-inspected bill images and bills corresponding to third bill information; whena bill identification model is trained, various bills including handwritten bills and value-added tax invoices are taken as training samples, so that the bill identification model can recognize commonhandwritten bills and value-added tax invoices, the inspection efficiency of the handwritten bills is greatly improved, and manpower consumption is reduced.
